    Publication Date: 2024-02-15
    Description: Con motivo de la renovación de la flota del Instituto Nacional de Investigación y Desarrollo Pesquero (INIDEP), surgió inmediatamente qué nombre se pondría al nuevo barco que se estaba construyendo en el Astillero Armón de Vigo, España, desde marzo de 2016. El nombre a un barco es como darle un nombre al hijo, donde los padres procuran homenajearlo con una designación significativa. En general los nombres de buques científicos se refieren a lugares geográficos, nombres en latín de organismos marinos interesantes y el nombre de algún investigador relacionado con las ciencias marinas a quien se desea recordar. En septiembre de 2016 la Dirección del INIDEP convocó a todo el personal para que propusieran posibles nombres para el nuevo barco. Posteriormente se hizo una votación sobre la lista presentada y resultó elegido el nombre "Víctor Angelescu". Las siguientes líneas se proponen mostrar quien fue el Dr. Víctor Angelescu a través de su actuación, sus trabajos, su personalidad y la opinión de quienes tuvimos el placer de conocerlo personalmente.

    Description: Abstract There is evidence that the tsunami as a destructive natural phenomenon has been known since antiquity. Although rare, tsunamis can affect densely populated areas, provoking heavy destruction and extensive casualties. A deep knowledge of their characteristics, such as generation mechanism, propagation, and effects is fundamental to assess the tsunami hazard of a region. Therefore, as for all natural events, also for tsunamis the observation and analysis of past occurrences is the basis of understanding the phenomenon. The study of historical tsunami records is the first step for hazard evaluation and for the calibration and validation of numerical models aimed at tsunami mitigation. This work wishes to emphasize the importance and limitations of historical data and catalogue in tsunami hazard assessment and to underline problems related to the critical interpretation and evaluation of historical sources.

    Description: Este artículo tiene por finalidad mostrar cómo un grupo de investigación dedicado a la etnobotánica resolvió el problema de conservar, ordenar y organizar una colección de material que no reúne las condiciones para ser incorporada en un herbario. Al mismo tiempo, se hace una breve revisión de varios tópicos y referencias sobre los distintos tipos de colecciones que realiza un etnobotánico y se sugieren ideas de cómo proceder con ellas.En apretada síntesis, el material documental que abarca la investigación etnobotánica compromete varios tipos de elementos, todos ellos habitualmente obtenidos in situ: a) material de herbario, b) órganos vegetales, trozos, fragmentos, material semielaborado (fibras, cordeles, etc.), c) material elaborado (artesanías, artefactos u objetos que conforman la cultura material), d) piezas complejas (tejidos, vestimentas, embarcaciones, mobiliario, adornos ceremoniales, etc. ), e) material de descarte o accesorio (tapones, tizones, envoltorios, parasoles, elementos de sostén o apoyo momentáneo, utensilios efímeros, etc.).

    Description: A través de esta nueva serie tratamos de conocer diferentes aspectos personales de los integrantes de la comunidad ictiológica iberoamericana.Esta iniciativa, comparte el espíritu y objetivo de las semblanzas nacionales buscando informalmente, otro punto de unión en la “comunidad de ictiólogos iberoamericanos”.Quizás esté equivocado en mi apreciación, pero creo que vale la pena este intento, ya que, con la colaboración generosa e insoslayable de los integrantes de este “universo”, señalaremos un registro en el tiempo de la Ictiología Neotropical.

    Description: Los anfípodos constituyen uno de los grupos de crustáceos peracáridos más importantes, tanto a nivel mundial como en Cuba. Se presentan los resultados de los estudios realizados sobre la taxonomía de los anfípodos cubanos. En la actualidad se registran cerca de 200 especies marinas, dulciacuícolas y troglobias. El archipiélago cubano, puede ser considerado como la zona del trópico americano donde el grupo resulta mejor conocido. También, donde se cuenta con un número mayor de especies nuevas descritas. Los anfípodos hipéridos (Suborden Hyperiidea), en particular, han permanecido muy poco estudiados en el país. Los bentónicos (Subórdenes Colomastigidea, Senticaudata y Amphilochidea) han sido el principal objeto de atención hasta el presente. Se presenta una breve historia, la morfología general de estos crustáceos, así como las claves y las 208 figuras originales para la clasificación de 197 especies distribuídas en 14 familias, 23 géneros y 35 especies de hipéridos; una familia, un género y siete especies de colomastígidos; 27 familias, 27 géneros y 98 especies de senticaudados y 19 familias, 30 géneros y 56 especies de anfiloquídeos. Lo anterior, hace un total de 61 familias, 81 géneros y 197 especies. Además, se registra por primera vez Dulichiella terminos, para Cuba. Finalmente, se adjunta, una tabla con las especies citadas hasta que comenzaron los estudios, en 1976, así como un glosario de términos.
    Description: Amphipods constitute one of the most important groups of peracarid crustaceans, both globally and in our country. The results of the studies carried out, since the beginning of our taxonomic investigations, of these interesting and abundant peracarid crustaceans are presented. Currently, slightly less than 200 marines, freshwater and troglobian species are registered. The Cuban archipelago can be considered as the area of the American tropics where the group is best known. Also, where there is a greater number of new species described. The hyperiid (Suborder Hyperiidea), in particular, have remained very little studied in the country. The benthic ones (Suborders Colomastigidea, Senticaudata and Amphilochidea), have been the main object of attention, until the present. A brief history, the general morphology, as well as the keys and the 208 original figures, for the classification of 197 species, distributed in 14 families, 23 genera and 35 Hyperiid species; a family, a genus and seven species of Colomastigids; 27 families, 27 genera and 98 species of Senticaudads, and 19 families, 30 genera and 56 species of Ampilochids, are presented. So a total of 61 families, 81 genera and 197 species are pointed out. In addition, Dulichiella terminos, is registered for the first time in Cuba. Finally, a table with the species cited until this studies began, in 1976, as well as a glossary of terms are offered.

    Description: We present to the international scientific community three important works by Father Maccioni adapted into English with several parts literally translated. The investigation into the existence of an electromagnetic (EM) seismic precursor was carried on in Italy in the beginning of the twentieth century and exploited the capabilities of a specifically designed coherer. For several reasons, both the work and the author are widely unknown even in Italy. We think this is likely to be the very first historical case of a study of a seismic precursor of the EM type

    Description: The Campi Flegrei volcano (or Phlegraean Fields), Campania, Italy, generated the largest eruption in Europe in at least 200 ka. Here we summarise the volcanic and human history of Campi Flegrei and discuss the interactions between humans and the environment within the “burning felds” from around 10,000 years until the 1538 CE Monte Nuovo eruption and more recent times. The region’s incredibly rich written history documents how the landscape changed both naturally and anthropogenically, with the volcanic system fuelling these considerable natural changes. Humans have exploited the beautiful landscape, accessible resources (e.g. volcanic ash for pulvis puteolana mortar) and natural thermal springs associated with the volcano for millennia, but they have also endured the downsides of living in a volcanically active region—earthquakes, signifcant ground deformation and landscape altering eruptions. The pre-historic record is detailed, and various archaeological sites indicate that the region was certainly occupied in the last 10,000 years. This history has been reconstructed by identifying archaeological fnds in sequences that often contain ash (tephra) layers from some of the numerous volcanic eruptions from Campi Flegrei and the other volcanoes in the region that were active at the time (Vesuvius and Ischia). These tephra layers provide both a relative and absolute chronology and allow the archaeology to be placed on a relatively precise timescale. The records testify that people have inhabited the area even when Campi Flegrei was particularly active.The archaeological sequences and outcrops of pyroclastic material preserve details about the eruption dynamics, buildings from Roman times, impressive craters that now host volcanic lakes and nature reserves, all of which make this region particularly mystic and fascinating, especially when we observe how society continues to live within the active caldera system. The volcanic activity and long record of occupation and use of volcanic resources in the region make it unique and here we outline key aspects of its geoheritage.

    Description: A discussion of several kinds of ether as they can be inferred from Geosciences, and what the existence of the ether could imply for Physics and Cosmology. A tribute to the memory of my mentor Franco Selleri.
    Description: This article is written in honor of my mentor Franco Selleri who has helped to consolidate my awareness of the existence of a medium subtended to ordinary matter, and from which everything comes. From my field, the Earth Sciences, come clues converging on an important role of the ether in the geological evolution of Earth and planets, as well as all the structures of the universe. Paleogeographic reconstructions allow a rough quantitative evaluation of the amount of new ordinary matter that is added to the planet in the unity of time, and the consequent statement of some cosmological consequences and on the inner energy balance of the Earth. The concept of central flow of ether defended here is different from the Lorentian stationary ether, but the two concepts could be made compatible.

    Description: Zgodnie z zapowiedzią ukazała się książka Macieja Krzeptowskiego „Pół wieku i trzy oceany”, wydana przez Morski Instytut Rybacki w Gdyni z okazji swego 85-lecia. Książka przedstawia historię polskiego rybołówstwa dalekomorskiego, ale opowiedzianą przez tych, którzy ją tworzyli. W sposób interesujący pokazuje współpracę Morskiego Instytutu Rybackiego z rybołówstwem dalekomorskim w odkrywaniu nowych łowisk. W książce Czytelnik znajdzie również sporo relacji ze spotkań z żeglarzami, których trasy rejsów często prowadziły przez łowiska rybackie. Jedni i drudzy to twardzi ludzie, a łączy ich morze. Również autor tej książki, Maciej Krzeptowski jest nie byle jakim żeglarzem. S/y. „Marią” opłynął świat, co w odrębnej książce opisał. W tej zaś z całego morza wspomnień rybaków zebrał te, które dotyczyły polskiej działalności rybackiej na oceanach świata, aby ich cząstkę ocalić od zapomnienia. Książka jest świetnie napisana, ze swadą morskiego „Sabały”, co nie dziwi, bo Maciej Krzeptowski to góral z Sabałowego rodu. Zawiera wiele, często zabawnych wspomnień, jakie trudno znaleźć w innych publikacjach. Jest ilustrowana znakomitymi zdjęciami z różnych rejonów połowów. Według znanego historyka polskiego rybołówstwa prof. A. Ropelewskiego „lektura tej książki będzie sprawiała dużą przyjemność, tym zwłaszcza, którzy lata całe spędzali na pokładach statków łowczych, pomocniczych i badawczych polskiego rybołówstwa dalekomorskiego. Znajdą zapewne na kartach tej książki żywe echa własnych przeżyć i doznań, wyniesionych z pogoni za rybą na łowiskach całego świata”.

    Morski Instytut Rybacki | Gdynia, Poland
    Publication Date: 2021-05-19
    Description: W czerwcu 2001 roku mija osiemdziesiąt lat od powołania pierwszej polskiej placówki badań morza - Morskiego Laboratorium Rybackiego w Helu. Naukową opiekę nad Morskim Laboratorium Rybackim, początkowo podległym Morskiemu Urzędowi Rybackiemu w Wejherowie, sprawował Uniwersytet Poznański. Od 1925 roku Morskie Laboratorium Rybackie zostało podporządkowane Państwowemu Instytutowi Naukowemu Gospodarstwa Wiejskiego w Puławach, który podlegał z kolei Ministerstwu Rolnictwa. Sprawy przyszłości Laboratorium zaczęły się komplikować, kiedy w 1927 roku zagadnienia rybołówstwa morskiego przejęło Ministerstwo Przemysłu i Handlu, a w Warszawie w 1928 roku powołano stowarzyszenie Morski Instytut Rybacki subwencjonowane częściowo przez Ministerstwo Przemysłu i Handlu. W konsekwencji Morskie Laboratorium Rybackie znalazło się poza obszarem kompetencji zarówno Ministerstwa Przemysłu i Handlu, jak i Ministerstwa Rolnictwa, które redukując wydatki na badania naukowe w podległym mu Państwowym Instytucie Naukowym Gospodarstwa Wiejskiego, doprowadziło w 1931 roku do likwidacji Morskiego Laboratorium Rybackiego. Dobra materialne i intelektualne zlikwidowanego laboratorium przejęła Stacja Morska w Helu, powołana w 1932 roku w wyniku działań podjętych przez Ministerstwo Przemysłu i Handlu oraz Ministerstwo Wyznań Religijnych i Oświecenia Publicznego. W końcu 1938 roku Stacja Morska została przeniesiona do Gdyni. Po wojnie placówkę tę reaktywowano pod pierwotną nazwą Morskiego Laboratorium Rybackiego. W 1945 roku wznowiło również działalność stowarzyszenie Morski Instytut Rybacki pod komisarycznym zarządem państwowym, podporządkowe Ministerstwu Żeglugi. W 1949 roku nastąpiło włączenie Morskiego Laboratorium Rybackiego do Morskiego Instytutu Rybackiego, który przejął przedwojenną siedzibę Stacji Morskiej w Gdyni. Szczegółowy opis wszystkich perypetii organizacyjnych pierwszej polskiej placówki badań morza znajdą czytelnicy w oddawanej im właśnie do rąk pracy profesora Andrzeja Ropelewskiego. Pozwoliłem sobie na skrótowe przywołanie chronologii tych wydarzeń, aby wykazać, że pomimo licznych zmian instytucjonalnych i organizacyjnych w dziedzinie badań rybackich w Polsce zachowana została ich ciągłość oraz w pewnym zakresie również baza materialna, a tym samym istnieje uzasadnienie uroczystych obchodów jubileuszu osiemdziesięciolecia Morskiego Instytutu Rybackiego. Namawiając profesora Ropelewskiego do podjęcia się trudu przygotowania tej pozycji wydawniczej, zdawaliśmy sobie sprawę, że krąg ewentualnych odbiorców może ograniczać się do grona pracowników Morskiego Instytutu Rybackiego i ich rodzin, a przypuszczalnie również, choć w mniejszym stopniu, do ludzi związanych z polskim rybołówstwem w drugiej połowie ostatniego stulecia. Profesor Ropelewski ze skrupulatnością typową dla historyka stworzył nie tylko szczegółową kronikę wydarzeń z historii Morskiego Instytutu Rybackiego i jego pracowników, ale osadził ją w kontekście znacznie wykraczającym poza obszar spraw związanych z samym Instytutem i rybołówstwem. Mam więc nadzieję, że ta pozycja, adresowana początkowo do wąskiego grona czytelników, zamówiona i wydana dla uświetnienia Jubileuszu Instytutu, zainteresuje również szerszy krąg odbiorców. Mam tu na myśli tych wszystkich, którzy niekoniecznie byli lub są związani zawodowo z rybołówstwem, ale poczuwająsię do związków z szerzej pojmowaną gospodarką morską i nauką. Na przykładzie zmiennych kolei losu Morskiego Instytutu Rybackiego na przestrzeni omawianego osiemdziesięciolecia, obejmujących okresy rozwoju, stagnacji, a ostatnio stopniowego ograniczania zatrudnienia i zakresu działalności, baczny czytelnik zauważy zapewne analogie nie tylko do ogólnej sytuacji rybołówstwa, ale czasami również nauki, a nawet polityki morskiej państwa. Morski Instytut Rybacki był, jest i zapewne nadal będzie związany z rybołówstwem morskim. Doświadczenia osiemdziesięciu lat wykazują że to właśnie potrzeby tej branży w znacznym stopniu decydowały o wielkości zatrudnienia i profilu kadry naukowej Instytutu oraz tematyce i geograficznej lokalizacji prowadzonych badań. Ze względu na nieodwracalny spadek udziału i znaczenia połowów dalekomorskich polskiego rybołówstwa, a tym samym ograniczenie zasadniczych rejonów badań do Morza Bałtyckiego, przed Instytutem stoją w dalszym ciągu duże wyzwania. Wyzwania te przede wszystkim dotyczą konieczności sprostania nowym międzynarodowym wymogom związanym z przystępowaniem Polski do Unii Europejskiej. W największym uproszczeniu wymogi te dotyczą istotnej zmiany podejścia do badań rybackich, od dotychczasowych badań ukierunkowanych głównie na obiekt połowów - ryby, do badań interdyscyplinarnych obejmujących szeroki zakres relacji pomiędzy ekosystemem i rybołówstwem. Takie podejście promuje m. in. Międzynarodowa Rada Badań Morza i Organizacja do Spraw Wyżywienia i Rolnictwa Narodów Zjednoczonych. Zalecana zmiana profilu badań rybackich stanowić może szansę rozwoju Morskiego Instytutu Rybackiego, mimo zmniejszającej się roli rybołówstwa morskiego w gospodarce naszego kraju. W okresie osiemdziesięciu.lat swojej działalności MIR stał się instytucją, której dokonania znane są w kraju i zagranicą. Pomimo ogólnie znanych trudności finansowych nauki polskiej potencjał materialny i intelektualny Instytutu, tworzony przez tak długi okres, pozwala zachować pewien optymizm na przyszłość i mieć nadzieję, że nie zostanie on zmarnowany.

    Description: We measured the personalities, values, and preferences of more than 19,000 people who ranged in age from 18 to 68 and asked them to report how much they had changed in the past decade and/or to predict how much they would change in the next decade. Young people, middle-aged people, and older people all believed they had changed a lot in the past but would change relatively little in the future. People, it seems, regard the present as a watershed moment at which they have finally become the person they will be for the rest of their lives. This "end of history illusion" had practical consequences, leading people to overpay for future opportunities to indulge their current preferences.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Quoidbach, Jordi -- Gilbert, Daniel T -- Wilson, Timothy D -- P01 AG020166/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2013 Jan 4;339(6115):96-8. doi: 10.1126/science.1229294.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Fund for Scientific Research, Brussels, Belgium.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23288539" target="_blank"〉PubMed〈/a〉

    Description: The vast majority of Mesozoic and early Cenozoic metatherian mammals (extinct relatives of modern marsupials) are known only from partial jaws or isolated teeth, which give insight into their probable diets and phylogenetic relationships but little else. The few skulls known are generally crushed, incomplete or both, and associated postcranial material is extremely rare. Here we report the discovery of an exceptionally large number of almost undistorted, nearly complete skulls and skeletons of a stem-metatherian, Pucadelphys andinus, in the early Palaeocene epoch of Tiupampa in Bolivia. These give an unprecedented glimpse into early metatherian morphology, evolutionary relationships and, especially, ecology. The remains of 35 individuals have been collected, with 22 of these represented by nearly complete skulls and associated postcrania. These individuals were probably buried in a single catastrophic event, and so almost certainly belong to the same population. The preservation of multiple adult, sub-adult and juvenile individuals in close proximity (〈1 m(2)) is indicative of gregarious social behaviour or at least a high degree of social tolerance and frequent interaction. Such behaviour is unknown in living didelphids, which are highly solitary and have been regarded, perhaps wrongly, as the most generalized living marsupials. The Tiupampan P. andinus population also exhibits strong sexual dimorphism, which, in combination with gregariousness, suggests strong male-male competition and polygyny. Our study shows that social interactions occurred in metatherians as early as the basal Palaeocene and that solitary behaviour may not be plesiomorphic for Metatheria as a whole.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ladeveze, Sandrine -- de Muizon, Christian -- Beck, Robin M D -- Germain, Damien -- Cespedes-Paz, Ricardo -- England -- Nature. 2011 Jun 2;474(7349):83-6. doi: 10.1038/nature09987.

    Description: We describe the Miocene–Quaternary geological–structural evolution of the region between the Salar de Uyuni and de Atacama, Andes of Chile and Bolivia. We recognized four main tectonic events based on fold geometry, fault kinematics and stratigraphic data. The oldest event, of Miocene age, is characterized by folding and reverse faulting of the sedimentary successions with an E–W direction of shortening in the northern part of the studied area and a WNW–ESE shortening in the southern part. The following two events, of Pliocene age, are characterized by lower shortening amounts; they occurred first by reverse faulting with a NW–SE-trending greatest principal stress (ó1, computed with striated fault planes) and a vertical least principal stress (ó3), followed by pervasive strike-slip faulting with the same NW–SE-trending ó1 and a horizontal NE–SW ó3. The fourth event, dating to the late Pliocene–Quaternary is characterized by normal faulting: the ó3 still trends NE–SW, whereas the intermediate principal stress ó2 exchanged with ó1. Volcanism accompanied both the contractional, transcurrent and extensional tectonic phases. The Mio–Pliocene compression appears directly linked to a rapid convergence and an apparently important coupling between the continental and oceanic plates. The E–W to WNW–ESE direction of shortening of the Miocene structures and the NW–SE ó1 of the Pliocene structures seem to be more linked to an intra-Andean reorientation of structures following the WNW-directed absolute motion of the South-American Plate. The extensional deformations can be interpreted as related to gravity forces affecting the highest parts of the volcanic belt in a sort of asymmetrical (SW-ward) collapse of the belt.

    Description: A large amount of unidentified material of the Neotropical genus Guatteria (Annonaceae) is lying on herbarium shelves around the world. Here twelve species are described in an attempt to reduce this amount of unidentified material. Next to this, previously unidentified material is now assigned to G. asplundiana, G. microcarpa, G. pastazae, and G. scalarinervia, four previously described but poorly known species, thus providing a clearer circumscription of these species. Furthermore, G. discolor and G. megalophylla appear to have a wider distribution than previously thought. Lastly, G. macrantha, a curious species only known from the type, is excluded from the genus and referred to Uvaria. With the description of twelve new species and the synonymizing of one, the total number of species in Guatteria adds up to over 300, thus rivalling Inga (Fabaceae) and Ocotea (Lauraceae) for the status of largest genus of Neotropical trees.

    Description: Coupled climate-carbon cycle models suggest that Amazon forests are vulnerable to both long- and short-term droughts, but satellite observations showed a large-scale photosynthetic green-up in intact evergreen forests of the Amazon in response to a short, intense drought in 2005. These findings suggest that Amazon forests, although threatened by human-caused deforestation and fire and possibly by more severe long-term droughts, may be more resilient to climate changes than ecosystem models assume.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Saleska, Scott R -- Didan, Kamel -- Huete, Alfredo R -- da Rocha, Humberto R -- New York, N.Y. -- Science. 2007 Oct 26;318(5850):612.

    Description: This paper deals with a famous private natural history collection of the court, transformed to a public collection of the state. Associated is a very important question: how cultural and political structures became a dimension of a collection. In order to establish a Court Natural History Cabinet of its own, separate from other collections (\xe2\x80\x9cPhysical Cabinet,\xe2\x80\x9d The Coin and Antique Collection), Emperor Franz Stephan von Lothringen (1708- 1765) decides in the middle of the 18th century to buy the famous \xe2\x80\x98museo\xe2\x80\x99 of Jean de Baillou, who had worked as a director of gardens and mines in Tuscany. The Collection of de Baillou consisted mainly of minerals, which were collected in Italy (some came from famous places all over the world), and fossils, particularly mussels, snails and crustaceans. It was one of the most famous and richest European collections of its type. It represented the Emperor\xe2\x80\x99s passion for science, modern \xe2\x80\x98know-how\xe2\x80\x99 and his self-confidence at being a personal centre, not for politics, but for special taste. The Emperor spent a lot of money on the collection. Furthermore, he sent naturalists to collect specimens and thus increase the collection. The Collection was the emperors private treasure and was placed near the Library of the Viennese court. De Baillou became managing director for life and after his death was succeeded by his son. In the first decades no catalogue was made. After twenty years, following the death of Franz Stephan von Lothringen, Maria Theresia wanted to have a survey about the collections of the court. Ignaz von Born, who had already made a name for himself at the Prague mint was appointed to write a first catalogue of the collection. He pointed out the low standard of the natural history collection and the scientific necessity of a rich mineral collection. It was also a time in which the government started to work against particularism in administration. The government also tried to get more evidence of minerals of all countries governed by the Habsburg Monarchy. The mining administration at Vienna ordered the mine inspectors in the periphery to send up documentation of minerals and rocks, which were found there. Thus, the transfer represents a new concept of scientific interest in a political dimension. Treasure no longer had priority.

    Description: A comparative analysis of 23 populations of the Brazil nut tree (Bertholletia excelsa) across the Brazilian, Peruvian, and Bolivian Amazon shows that the history and intensity of Brazil nut exploitation are major determinants of population size structure. Populations subjected to persistent levels of harvest lack juvenile trees less than 60 centimeters in diameter at breast height; only populations with a history of either light or recent exploitation contain large numbers of juvenile trees. A harvesting model confirms that intensive exploitation levels over the past century are such that juvenile recruitment is insufficient to maintain populations over the long term. Without management, intensively harvested populations will succumb to a process of senescence and demographic collapse, threatening this cornerstone of the Amazonian extractive economy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Peres, Carlos A -- Baider, Claudia -- Zuidema, Pieter A -- Wadt, Lucia H O -- Kainer, Karen A -- Gomes-Silva, Daisy A P -- Salomao, Rafael P -- Simoes, Luciana L -- Franciosi, Eduardo R N -- Cornejo Valverde, Fernando -- Gribel, Rogerio -- Shepard, Glenn H Jr -- Kanashiro, Milton -- Coventry, Peter -- Yu, Douglas W -- Watkinson, Andrew R -- Freckleton, Robert P -- New York, N.Y. -- Science. 2003 Dec 19;302(5653):2112-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centre for Ecology, Evolution and Conservation, School of Environmental Sciences, University of East Anglia, Norwich NR4 7TJ, UK.

    Description: Mitochondrial DNA sequences isolated from ancient dog remains from Latin America and Alaska showed that native American dogs originated from multiple Old World lineages of dogs that accompanied late Pleistocene humans across the Bering Strait. One clade of dog sequences was unique to the New World, which is consistent with a period of geographic isolation. This unique clade was absent from a large sample of modern dogs, which implies that European colonists systematically discouraged the breeding of native American dogs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Leonard, Jennifer A -- Wayne, Robert K -- Wheeler, Jane -- Valadez, Raul -- Guillen, Sonia -- Vila, Carles -- New York, N.Y. -- Science. 2002 Nov 22;298(5598):1613-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Organismic Biology, Ecology and Evolution, University of California, Los Angeles, CA 90095-1606, USA.

    Description: Long sediment cores recovered from the deep portions of Lake Titicaca are used to reconstruct the precipitation history of tropical South America for the past 25,000 years. Lake Titicaca was a deep, fresh, and continuously overflowing lake during the last glacial stage, from before 25,000 to 15,000 calibrated years before the present (cal yr B.P.), signifying that during the last glacial maximum (LGM), the Altiplano of Bolivia and Peru and much of the Amazon basin were wetter than today. The LGM in this part of the Andes is dated at 21,000 cal yr B.P., approximately coincident with the global LGM. Maximum aridity and lowest lake level occurred in the early and middle Holocene (8000 to 5500 cal yr B.P.) during a time of low summer insolation. Today, rising levels of Lake Titicaca and wet conditions in Amazonia are correlated with anomalously cold sea-surface temperatures in the northern equatorial Atlantic. Likewise, during the deglacial and Holocene periods, there were several millennial-scale wet phases on the Altiplano and in Amazonia that coincided with anomalously cold periods in the equatorial and high-latitude North Atlantic, such as the Younger Dryas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baker, P A -- Seltzer, G O -- Fritz, S C -- Dunbar, R B -- Grove, M J -- Tapia, P M -- Cross, S L -- Rowe, H D -- Broda, J P -- New York, N.Y. -- Science. 2001 Jan 26;291(5504):640-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Duke University, Division of Earth and Ocean Sciences, Durham, NC 27708, USA. pbaker@geo.duke.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11158674" target="_blank"〉PubMed〈/a〉

    Description: Amazonian rain forest-savanna boundaries are highly sensitive to climatic change and may also play an important role in rain forest speciation. However, their dynamics over millennial time scales are poorly understood. Here, we present late Quaternary pollen records from the southern margin of Amazonia, which show that the humid evergreen rain forests of eastern Bolivia have been expanding southward over the past 3000 years and that their present-day limit represents the southernmost extent of Amazonian rain forest over at least the past 50,000 years. This rain forest expansion is attributed to increased seasonal latitudinal migration of the Intertropical Convergence Zone, which can in turn be explained by Milankovitch astronomic forcing.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Mayle, F E -- Burbridge, R -- Killeen, T J -- New York, N.Y. -- Science. 2000 Dec 22;290(5500):2291-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geography, University of Leicester, Leicester LE1 7RH, UK. fem1@leicester.ac.uk〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11125139" target="_blank"〉PubMed〈/a〉

    Notes: Abstract Large-scale coral bleaching episodes are potentially major disturbances to coral reef systems, yet a definitive picture of variation in assemblage response and species susceptibilities is still being compiled. Here, we provide a detailed analysis of the bleaching response of 4160 coral colonies, representing 45 genera and 15 families, from two depths at four sites on reefs fringing inshore islands on the Great Barrier Reef. Six weeks after the onset of large-scale bleaching in 1998, between 11 and 83% of colonies along replicate transects were affected by bleaching, and mortality was 1 to 16%. There were significant differences in bleaching response between sites, depths and taxa. Cyphastrea, Turbinaria and Galaxea were relatively unaffected by bleaching, while most acroporids and pocilloporids were highly susceptible. The hydrocorals (Millepora spp.) were the most susceptible taxa, with 85% mortality. Spatial variation in assemblage response was linked to the taxonomic composition of reef sites and their bleaching history. We suggest, therefore, that much of the spatial variation in bleaching response was due to assemblage composition and thermal acclimation.

    Notes: Abstract The modern scientific study of desiccation tolerance began in 1702 when Anthony von Leeuwenhoek discovered that rotifers could survive without water for months. By 1860, the controversy over whether organisms could dry up without dying had reached such a pitch that a special French commission was convened to adjudicate the dispute. In 2000, we know that a few groups of animals and a wide variety of plants can tolerate desiccation in the active, adult stages of their life cycles. Among plants, this includes many lichens and bryophytes, a few ferns, and a very few flowering plants, but no gymnosperms nor trees. Some desiccation-tolerant species can survive without water for over ten years, recover from desiccation to unmeasurably low water potentials, and, when plants are desiccated, endure temperature extremes from −272 to 100 °C. Desiccation-tolerant plants occur on all continents but mainly in xeric habitats or microhabitats where the cover of desiccation-sensitive species is low. Two main puzzles arise from these patterns: What are the mechanisms by which plants tolerate desiccation? and Why are desiccation-tolerant plants not more ecologically widespread? Recent molecular and biochemical studies suggest that there are multiple mechanisms of tolerance, many of which involve protection from oxidants and from the loss of configuration of macromolecules during dehydration. Hypotheses to explain the restricted ecological range of desiccation-tolerance plants include inability to maintain a cumulative positive carbon balance during repeated cycles of wetting and drying and inherent trade offs between desiccation tolerance and growth rate.

    Notes: Abstract In 1824 Hering introduced an indicator-dilution method for measuring blood velocity. Not until 1897 was the method extended by Stewart to measure blood (volume) flow. For more than two decades, beginning in 1928, Hamilton and colleagues measured blood flow, including cardiac output. They proposed that the first-passsage indicator concentration-time curve could be recovered from observed curves that included recirculation by semilogarithmic extrapolation of the early downslope. Others followed with attempts to fit the complete first-passage curve by various forms, such as by the sum of three exponential terms (three well-stirred compartments in series). Stephenson (1948) thought of looking at indicator-dilution curves as convolutions of indicator input with a probability density function of traversal times through the system. Meier and I reached a similar conclusion, and extended it. The fundamental notion is that there exists a probability density function of transit times, h(t), through the system. We proved that mean transit time t=V/F, where V is volume in which the indicator is distributed. Thus, V, F, and t might all be calculated, or t alone might suffice if one wanted only to know relative blood flow. I extended the analysis to include residue detection of indicator remaining in the system, so that V, F, and t could be calculated by external monitoring. Chinard demonstrated the value of simultaneous multiple indicator-dilution curves with various volumes of distribution. Goresky extended the technique to study cell uptake and metabolism. He also found a transform of indicator-dilution output curves (equivalent to multiplying the ordinate by t and dividing the time by t) which made congruent the family of unalike curves obtained by simultaneous injection of indicators with different volumes of distribution. Bassingthwaighte showed the same congruency with the transform of outputs of a single indicator introduced into a system with experimentally varied blood flows. We showed the same congruency for the pulmonary circulation, adding a correction for delays. Success of these transforms suggests that the architecture of the vascular network is a major determinant of the shape of density functions of transit times through the system, and that there is in this architecture, a high degree of self-similarity, implying that the fractal power function is a component in shaping the observed density of transit times. I proposed that the distribution of capillary critical opening pressures, which describes recruitment of vascular paths, may be important in shaping indicator-dilution curves, and that h(t) may be derived from flow-pressure and volume-pressure curves under some circumstances. © 2000 Biomedical Engineering Society.PAC00: 8719Uv, 0630Bp

    Notes: Abstract A comparative study of the regeneration ecology ofthree lesser-known leguminous timber species wasconducted in the seasonally dry forests of SantaCruz, Bolivia to determine species regenerationstrategies and make silvicultural recommendationsfor these species. The study included arepresentative from each subfamily of Leguminosae:Anadenanthera colubrina (Vell. Conc.) Benth.(Mimosaceae), Copaifera chodatiana Kunth.(Caesalpinaceae), and Centrolobium microchaeteC. Martius (Fabaceae). After production in themid-late dry season, seeds of all species sufferedhigh (〉30%) rates of predation. For seedssurviving predation, Anadenanthera germinatedwithin three days after the first rains and a highgermination capacity (82%), but most seedlings diedfrom inadequate light or during subsequent periodsof drought. Copaifera germinated more slowlybut had high germination capacity (85%). Centrolobium had very low germination capacity(4%) and germinative energy. Most successfulregeneration of Centrolobium occurred viasprouting from damaged roots on or near loggingroads where it had a density of 261 root sprouts/ha.Anadenanthera regenerated best from seedin areas with soil disturbance or burning. Theregeneration of these species will likely increaseunder more intensive logging and/or post-harvestcompetition control treatments in logging gaps. Themore shade-tolerant Copaifera is most suitedto the current regime of light selective logging,but all three species are likely to be responsive topost-harvest competition control treatments. Impacts of controlled and natural fire were mixed,but generally seedling regeneration and growth wereeither not significantly affected or were increasedby fire.

    Notes: Abstract The Noel Kempff Climate Action Project in Bolivia, nowin its third year, is breaking ground to establishcredible and verifiable methods to quantify greenhousegas (GHG) benefits of land-use change and forestry (LUCF)projects. Developed under the United Nations FrameworkConvention Climate Change (FCCC) Activities ImplementedJointly pilot phase, the project conserves naturalforests that would otherwise have been subjected tocontinued logging and future agricultural conversion.Carbon (C) monitoring began with a C inventory of theproject area in 1997. The total amount of C in theproject area was 118 Tg (Tg = 1012g) ± 4%(95% confidence interval). Periodic monitoring ofrelevant C pools (occurring in 1999 and every 5 yrthereafter) occurs over the 30-year life of theproject to establish the difference between thewith-project and projected without-project scenarios. Permanent sample plots were established both insidethe project area to monitor changes in C pools overtime and in a proxy logging concession near theproject area to determine changes in C pools inforests that have been impacted by logging. Ground-based monitoring is complemented by datacollection on forest industry trends and land-usechange patterns. Remote sensing was used to developa vegetation stratification map of the area, and workis ongoing to investigate the potential application ofdual-camera aerial videography to improve theefficiency of monitoring over time.

    Notes: Abstract The origin of lunar craters has been discussed for centuries,since they were discovered by Galilei in 1609. The majority of researchers were of the opinion that they are volcanic structures, but a variety of “exotic” explanations that included tidal forces, circular glaciers, and coral atolls was also considered. The meteorite impact hypothesis had been discussed a few times, starting with Hooke in 1665, and formulated in more detail by Proctor in 1873 and Gilbert in 1893. However, this theory only gained momentum early in the 20th century, after the identification of Meteor Crater in Arizona as an impact structure, and after specific and plausible physical models for impact craters formation were devised by Öpik in 1916, Ives in 1919, and Gifford in 1924. Nevertheless, despite growing evidence for the interpretation that most craters formed by impact, proponents of the volcanic theory impact were still vociferous as late as 1965, just four years before the first samples were brought back from the moon. Important lessons could have been learned for the study of impact craters on the Earth, especially in view of evidence that large impactevents had some influence on the geologic and biologic evolution of the Earth.

    Notes: Abstract Overlapping patchworks of farm spatial units are characteristic of the mountain landscapes of Andean regions of Peru and Bolivia. Patchiness and overlap (200-600 m) are shaped by the broad tolerances of major crops, high variability/low predictability of habitat factors, multifaceted cropping rationales of cultivators including their linkages to extraregional influences, and, to varying extents, the sociospatial coordination of crop choice among farmers. Indian peasant farmers manage overlapping patchworks using a concept of farm spaces as loosely bounded. They apply a naming system to farm spatial units based primarily on topographic features in order to serve their cultural, social, and political purposes. Key processes suggest a regionalglobal model of overlapping patchworks. The model elucidates the roles of landscape flexibility and uncertainty in conservation-with-development. Implications are shown by farm units of diverse food plants and prospects for in situ conservation. Findings caution against universality of the zone model of mountain agriculture.

    Notes: Abstract The mechanisms underlying the photoperiodic entrainment of the endogenous circannual rhythm of maturation in the rainbow trout were investigated by subjecting December-spawning fish to abrupt changes in daylength which varied in their timing or magnitude. These protocols advanced spawning by up to 4 months. Maturation occurred in sequence in fish maintained on 18L:6D from January and February, and in fish exposed to 18L:6D from December, January and February, followed by 6L:18D in May, indicating that the abrupt increases in daylength were effective entraining cues. `Long' photoperiods of between 12 and 22 h applied in January, followed by shorter photoperiods of between 3.5 and 13.5 h from May, were equally effective in advancing maturation. Maturation was also advanced, though to a lesser extent, in fish maintained on photoperiods of 8.5 or 10 h from January, followed by a photoperiod of 1.5 h from May. In contrast, maturation was delayed in fish maintained under a constant 8.5-h photoperiod from January, and these fish also exhibited a desynchronization of spawning times characteristic of endogenous circannual rhythms in free-run. Collectively, these results indicate that photoperiodic history determines the reproductive response of rainbow trout to changes in daylength.

    Notes: Abstract Increasingly, there is greater appreciation of the impact of technology on marketing practice. Many strategies like mass customization, relationship marketing, interactive marketing, etc., have gained increased attention, in part, from advancements in manufacturing and information technology. In this paper, we formally examine how technology has made such strategies economically feasible through its impact on optimal segment size. We build on Lancaster's model of product differentiation to derive an equation that exposes the “invisible hand” of technology. This equation shows how technology influences marketing practice through its effect on optimal segment size. In addition, the equation provides a formal explanation for the apparent paradox of mass customization; that customized products can be mass-produced profitably, without the benefit of large production volumes. We then use this equation to gain a more insightful view of the history of segmentation.

    Notes: Abstract  This historical review of the progress of innovation in diamond research is discussed comparing it with the history of other materials. The innovation steps in current diamond technology are shaped by the fact that diamond is a functional material. This series of innovations was mainly brought about by the discovery of CVD methods of synthesizing diamond from the gas phase. Many kinds of expected applications have been proposed. Success in demonstrating diamond electronic devices has been achieved, and atomic scale observations on diamond growth are reported. Thus, even atomic scale control in synthesizing diamond looks quite realistic in the near future. Although such new data enhance the applications of diamond, most industrial applications of diamond still rely on its hardness. Innovation with diamond will be accelerated when a product using diamond as a functional material is used widely.

    Notes: Abstract. The paper addresses the issue of child labor in relation to the educational attainment of working children. The empirical analysis is based on household surveys in Bolivia and Venezuela. It was found that labor force participation is non-trivial among those below the legal working age or supposed to be in school. Working children contribute significantly to total household income. The fact that a child is working reduces his or her educational attainment by about 2 years of schooling relative to the control group of non-working children. Grade repetition, a common phenomenon in Latin America, is closely associated with child labor. JEL classification: J13, J21, I21

    Notes: Abstract Electrical and electromagnetic geophysical techniques have reached a high level of technological sophistication since they were first used in boreholes less than one hundred years ago. Borehole logging-the detailed determination of rock and fluid properties adjacent to the borehole, and borehole geophysics-extending the range of geophysical investigation large distances away from the borehole, are essential for exploration, assessment and production of earth resources, as well as for fundamental studies of the earth. Borehole electrical and electromagnetic methods incorporate 17 decades of the electromagnetic spectrum, from 1000-s geomagnetic studies, through resistivity and permittivity measurements, to high-resolution resistivity imaging, NMR and optical spectroscopy.

    Notes: Abstract A field survey/collection trip to Bolivia was carried out in 1994 in order to examine the present status of the leguminous tuber/root crop Pachyrhizus ahipa. The germplasm available prior to the field trip was very limited, only one accession of known origin and two of unknown origin were available for genetic analysis and agronomic evaluation. However, in order to ensure that information on cultivation practices, genetic variation and the need for conservation initiatives would become available to the biosystematic Yam Bean Project (funded by the EU/STD3 Programme), a detailed questionnaire was developed and used in the survey. The field trip succeeded in establishing the urgent need for conservation measurements, the considerable genetic variation available within the extant landraces, and the objectives of any future breeding programme. This species possesses numerous agronomically attractive traits.

    Notes: Synopsis The geological and biological history of Asian great lakes, especially Lake Biwa in Japan, are reviewed. The origins and affiliations of endemic flora and fauna are interpreted in light of current understanding of Lake Biwa. Recent historical changes in the lake, including detrimental impacts on native fauna and water quality are summarized. The social and cultural values associated with Asian lakes are reviewed, and contrasted to those of lakes elsewhere. In general Asian great lakes are smaller than those elsewhere, with the notable exception of Lake Baikal. Furthermore, Asian lakes are typically more eutrophic, with higher primary productivity. Societal values in China and other Asian countries have tended to favour nutrient enrichment and increased cultured fish production from lakes. Asian societies, however, have long attached important artistic, poetic and cultural values to their lakes.

    Notes: Abstract Investigations into the much-discussed question of a historical manmade water storage lake within the Fayum depression were carried out in spring 1988. The results of the research into the dam between Itsa and Shidmuh indicate that there existed an artificial lake in the south-east of the Fayum as early as the 3rd Cent. B.C. The findings are in agreement with the reports of the classical writers. There is no reason not to identify this lake in the El-Mala'a basin with the lake the ancient (post-Ptolemaic) historians and geographers referred to as Lake Moeris. The question as to whether Herodotus in the 5th Cent. B.C. described the same lake or whether he saw the water level of the Birket el-Qarun at 19 to 21 m must, at present, remain unanswered.

H. Becquerel and M. Curie, radiology with its diagnostic and therapeutic methods was made possible. The medical physicist has an important task to fulfill in modern radiotherapy, nuclear medicine and radiodiagnostics. The longtime interdisciplinary collaboration has won the international recognition of medical physics as a scientific discipline, a health care profession and a university subject. Several incidents, including contemporary ones, show that the efforts made towards radiation protection must remain an important domain of the specialist.

    Notes: Abstract This study is focused on the endorheic Uyni-Coipasa Basin located in the southern Bolivian Altiplano. Stratigraphical and fossil diatom studies based on a detailed radiocarbon chrnology revealed six phases in water-level changes and paleosalinity variations. At 15,430±80 yr B.P., lacustrine conditions settled in the southern Bolivian Altiplano. A saline lake, characterized by benthic meso-metasaline species, reached ∼+4 m altitude above the present bottom of the basin. After 15,430±80 yr B.P., the level rapidly rose to ∼+27 m, as suggested by a tychoplanktonic mesosaline flora. Between ∼14,500 years and ∼13,000 years, finely lanminated sediments at ∼+32 m contained successively a dominance of epiphytic mesosaline to hypersaline species and tychoplanktonic oligosaline diatoms, indicating weak fluctuations in water-level and salinity. At 13,000 years, strong changes in the diatom flora occurred; epiphytic oligo-hypersaline diatoms were replaced by planktonic meso-polysaline species. They indicate a deep salt lake (the lake reached ∼+100 m). After ∼12,000 years, the lake level abruptly dropped, as suggested by fluviatile sediments with a benthic mesopolysaline diatom flora. The main lake was replaced by shallow saline ponds. A wet pulse occurred at ∼11,400 years, characterized by low water level (∼+7 m) and high salinity. This lacustrine phase remained until 10,400 yr B.P. These data indicate changes in Precipitation minus Evaporation (P-E). Our regional interpretations are based on a comparison with teh available data on the northern (Lake Titicaca) and southern (Lipez are) Bolivian Altiplano and on the northern Chilean Altiplano (Atacama Desert).

Está caracterizada por una mezcla de tipos de vegetación, que incluye desde bosques montanos tropicales hasta bosques de tierras bajas y sabanas. Se encuentra en un rango altitudinal de 400–1850 m, con un promedio de temperature de 24–28°C y una precipitación de 2000–5000 mm por año. La riqueza de palmas en esta región es la más alta reportada para Bolivia: 19 géneros, que significan el 70% del total de géneros de palmas registrado para Bolivia y 29 especies de palmas (34%). Tres elementos fitogeográficos están mezclados e integrados en el área: en ca. 4.5 ha se encuentran palmas de los Andes, de la Amazonia y del Centro brasileño (cerrado). Aproximadamente el 66% de las especies de palmas está concentrado en los bosques montanos entre 500–1800 m, que alcanzan su mayor límite altitudinal en el área y donde la especie más común es Iriartea deltoidea. Cerca al 55% de las especies de palmas es utilizado por la gente local—como el grupo originario Tacanas y colonos-para la obtención de material de construcción, diferentes calidades de techos, frutos para alimento y bebidas, fibras para productos artesanales, medicinas y artesanías.
    Notes: Abstract The study site is located in the southern part of the Iturralde Province, Department of La Paz, in western Bolivia. This area is generally characterized by mixed vegetation types from the tropical mountain forests as well as lowland forests and savannas. It lies in an altitudinal range of 400–1850 m, with an average temperature of 24–28°C and a rainfall of 2000–5000 mm per year. The richness in palms of this region is the highest reported for Bolivia; it comprises 19 genera, 70% of all genera known in Bolivia and 29 palm species (34%). Three main phytogeographic elements are mixed and integrated in the area; palms from the Andean, Amazonian, and Central Brazilian (Cerrado) units are found in approximately 4.5 ha. Nearly 66% of these palm species are concentrated in the mountain forests between 500–1800 m, reaching the highest altitudinal limit in this area, of which the most common species is Iriartea deltoidea. Approximately 55% of the palm species are used by local people — the original ethnic group, the Tacanas, and settlers— in order to get materials for construction, different qualities of thatching, fruit for food and beverages, fibres for artesanal products, medicines and handicrafts.

    Notes: Abstract In France and the United States it has been shown that strong linkages exist between vegetation and alluvial landforms within homogeneous river stretches characterized by geomorphological processes, flood duration, flood magnitude, flood frequency, and sediment size. Furthermore, perturbations induced by man (such as embankments and damming) have been shown to have an effect on both succession and plant distribution patterns. Yet, in numerous cases it is not possible to find either the communities or the plants whose presence might be predicted by reference to the river section characteristics (such as straight, braided, anastomosed, or meandering channels) or by reference to perturbation effects well known in piedmont valleys (such as variations of the water-table depth, variations of magnitude, and frequency and duration of floods). Unexpected species, new communities, and even new successional sequences are often observed. The presence of new alluvial forms explains these differences. An “artificial” substratum generated by an old human perturbation (limited in the time) has been established in the past; consequently, the natural distribution patterns of water and matter flows have been disturbed. Archive research has enabled a classification of abandoned systems that were commonly used during the 16th, 17th, 18th, and 19th centuries on European floodplains. Several case studies were chosen in order to illustrate and explain the importance of stream corridor history. The example of the Isère River valley, downstream from Albertville, is chosen to highlight the heterogeneity of the vegetation mosaïc pattern outside the dikes. The historical reconstruction explains the role of the additional disturbances that cause deviation from the system evolution patterns.

    Notes: The protected areas of Bolivia cover 10.2% of its territory, but only 60% of this surface is considered to be of conservation value. Protected areas are unevenly distributed over the eight phyto-geographic regions of Bolivia. The Pantanal is not represented in any conservation unit. Inventories and basic information are usually lacking as plant surveys have been carried out mostly outside protected areas.

    Notes: Summary We conducted joint Bolivia/The Netherlands/United States wild potato (Solanum sect. Petota Dumort.) germplasm collecting expeditions in Bolivia from February 1-April 15, 1993, and January 1-February 26, 1994. The goals of the expeditions were to collect germplasm and gather data for continuing taxonomic studies of the approximately 43 taxa of Bolivian wild potatoes accepted by current taxonomists. We made 223 collections, 135 as true seed collections, 54 as tubers, 19 only as herbarium collections. Two recent taxonomic treatments of Bolivian wild and cultivated potatoes have clarified the taxonomy and distribution of these plants, but there are continuing disagreements between treatments regarding species boundaries and interrelationships. These disagreements, and the variability we observed in natural populations, present problems for identifications. We summarize the state of germplasm collections for Bolivia, provide our field data regarding the taxonomy of Bolivian wild potatoes, provide recommendations for future collecting, and provide new chromosome counts for S. hoopesii, S. ugentii, and S. yungasense.

    Notes: Abstract This paper provides quantitative information concerning the response of ostracods to environmental variability in order to reconstruct past environments. Ostracod faunas from modern sediments of Bolivian lakes and swamps were studied. Ostracod distribution is controlled by several ecological characteristics such as lake-level and water chemistry. Statistical results indicate that three transfer functions (on water depth, Total dissolved Salts and water in Mg/Ca ratio) can be developed, from ostracod species frequencies in lacustrine sediments, with some restrictions for the two last ones.

    Notes: Abstract The Late Pleistocene to Holocene eruptive history of Pico de Orizaba can be divided into 11 eurptive episodes. Each eruptive episode lasted several hundred years, the longest recorded being about 1000 years (the Xilomich episode). Intervals of dormancy range from millenia during the late Pleistocene to about 500 years, the shortest interval recorded in the Holocene. This difference could reflect either changes in the volcano's activity or that the older stratigraphic record is less complete than the younger. Eruptive mechanisms during the late Pleistocene were characterized by dome extrusions, lava flows and ash-and-scoria-flow generating eruptive columns. However, in Holocene time plinian activity became increasingly important. The increase in dacitic plinian eruptions over time is related to increased volumes of dacitic magma beneath Pico de Orizaba. We suggest that the magma reservoir under Pico de Orizaba is stratified. The last eruptive episode, which lasted from about 690 years bp until ad 1687, was initiated by a dacitic plinian eruption and was followed by effusive lava-forming eruptions. For the last 5,000 years the activity of the volcano has been gradually evolving towards such a trend, underlining the increasing importance of dacitic magma and stratification of the magma reservoir. Independent observations of Pico de Orizaba's glacier early this century indicate that some increase in volcanic activity occurred between 1906 and 1947, and that it was probably fumarolic.

    Notes: Abstract This paper creates a framework for the study of the history of tourism for climate and health. It traces the ways in which people have both moved away from detrimental health conditions and towards places thought to provide climatic cures. It brings to light the complex issues that have affected the course of the tourist trade. In this way it helps to explain that the modern geographical distribution of the highly fashionable resort areas of the world owe a great deal to past and present interpretations of the HippocraticCorpus.

    Notes: Abstract The benthic invertebrates fauna of most of the saline lakes of the Sud Lipez region (Bolivia, Altiplano) has been until now quite unstudied. Samples collected during an extensive survey of 12 lakes and two small inflow rivers allow a first list of the main macroinvertebrates living in these biotopes. The heterogeneous nature of these saline lakes with their freshwater springs and phreatic inflows offers a variety of habitats to macroinvertebrates. The benthic fauna in lakes with salinities 〉 10 g l−1 is not so low in density but includes few species and is dominated by Orthocladiinae and Podonominae larvae. In contrast, the freshwater springs and inflows are colonized by a diverse fauna, with a mixture of both freshwater and saline taxa, but dominated by Elmidae and Amphipoda. The lakes are quite isolated and, apart from some cosmopolitan organisms, their fauna can be quite distinctive.

    Notes: Synopsis The international phase of coelacanth research, meaning substantial activity and involvement by people from countries other than the Comoros, France and South Africa, began in 1961. In that year UNESCO initiated detailed planning for a multinational, multiyear investigation of many aspects of the physical, chemical and biological environments of the Indian Ocean that was called the International Indian Ocean Expedition (IIOE). In response to a request for proposals for the United States' program in biology in the IIOE the author, early in 1961, initiated a plan for what became a 3-month long expedition by 15 scientists from three countries on board the R/V TE VEGA. In 1964 the expedition went to northern Madagascar and the Comoro Islands. Efforts to capture and study at least one specimen of Latimeria were a major component of the activities. This paper describes important aspects of the preparations leading up to this expedition and the events that occurred during the expedition, in the context of the search for the coelacanth. The expedition did not capture a fish itself, but arrangements made during the trip resulted in a specimen (CCC no. 37), partly fixed in formalin and then frozen, being sent to the author in early 1965. A detailed study of the fats and oils contained in this fish resulted in a prediction concerning the probable neutral buoyancy of Latimeria that has been supported by the recent behavioral observations from submersibles. The paper concludes with a brief account of the activities of the Committee on Latimeria that was sponsored by the U.S. National Academy of Sciences from 1968–1972.

    Notes: Abstract Most proof methods for reasoning about concurrent programs are based upon theinterleaving semantics of concurrent computation: a concurrent program is executed in a stepwise fashion, with only one enabled action being executed at each step. Interleaving semantics, in effect, requires that a concurrent program be executed as a nondeterministic sequential program. This is clearly an abstraction of the way in which concurrent programs are actually executed. To ensure that this is a reasonable abstraction, interleaving semantics should only be used to reason about programs with “simple” actions; we call such programs “atomic”. In this paper, we formally characterise the class of atomic programs. We adopt the criterion that a program isatomic if it can be implemented in a wait-free, serialisable manner by a primitive program. A program isprimitive if each of its actions has at most one occurrence of a shared bit, and each shared bit is read by at most one process and written by at most one process. It follows from our results that the traditionally accepted atomicity criterion, which allows each action to have at most one occurrence of a shared variable, can be relaxed, allowing programs to have more powerful actions. For example, according to our criterion, an action can read any finite number of shared variables, provided it writes no shared variable.

    Notes: Abstract Intraplate seismic activity in Bolivia is mainly located in the central region (16°–19°S, 63°–67°W) which includes the East Andean Cordillera and the Sub-Andean Sierras. At this region there is a bend in the trend of the main geological structures from NW-SE in the north to N-S in the south. Focal mechanisms have been calculated for 10 earthquakes of magnitudes 4.9–5.6, using first motionP-waves from long period instruments. Their solutions correspond to reverse faulting, some with a large component of strike-slip motion. Their solutions can be grouped into two types; one with pure reverse faulting on planes with azimuth NW-SE and the other with a large strike-slip component on planes with azimuths nearly N-S or WNW-ESE. The maximum stress axis (P-axis) is practically horizontal (dipping less than 5°) oriented in a mean N56°E direction. This orientation may be related with the direction of compression resulting from the collision of the Nazca plate against the western margin of the South American continent. Wave-form analysis of long-periodP-waves for one event restricts the focal depth to 8 km in the Sub-Andean region. Seismic moments and source dimensions determined from spectra of Rayleigh waves are in the range of 1016–1017Nm and 17–24 km, respectively. The Central Bolivia region can be considered as a zone of intraplate deformation situated between the Bolivian Altiplano and the Brazil shield.

    Notes: Abstract A histological study of the pulmonary vasculature in a young male high-altitude Aymara Indian revealed four aspects of interest. There was muscularization of the terminal portion of the pulmonary arterial tree to involve pulmonary arterioles as small as 15 μm in diameter, thus forming a basis for the slightly increased pulmonary vascular resistance of native highlanders. Intimal longitudinal muscle was found in pulmonary arteries and arterioles and thought to be due to chronic alveolar hypoxia. Inner muscular tubes similar to those found in chronic obstructive lung disease were present. Pulmonary veins and venules also showed intimal muscularization suggesting that alveolar hypoxia affects vascular smooth muscle cells per se irrespective of their situation. The nature of the remodelling in a pulmonary blood vessel depends on a combination of hypoxia and haemodynamics.

    Notes: Abstract Biometeorology in Austria has been shaped by concepts, personalities, and technology. In early times, the branches of biometeorology that are usual today were already evident: agricultural and forest meteorology, phenology, medical biometeorology and balneology, aerial biometeorology, urban housing and stabling meteorology all started to emerge several centuries ago. From the 1920 up to 1936, Wilhelm Schmidt at the Agricultural University of Austria laid the foundations of modern biometeorology. He was followed by Franz Sauberer, who headed a Department of Biometeorology at the National Weather Service and devoted his active life totally to biometeorology. Several years after his untimely death, the Department was dissolved. Not until 1981 was biometeorology taken up again at the Agricultural University, where the tradition of Schmidt and Sauberer now lives on in several courses within the area of applied biometeorology: Micro-and Topoclimatology, Agricultural and Forest Meteorology and Atmospheric Radiation. Biometeorology, being an experimental science, has also been influenced by new technological developments. The early period was exclusively observational. During the late nineteenth and early twentieth centuries mechanical and simple electric instruments were used with strip-chart recorders. These time consuming methods have now been replaced by electronic devices, including data loggers and portable computers along with many new electronic sensors, which provide additional insight into biometeorological problems. Since computers also make it possible to solve some of the complicated equations of biometeorology, the future of this science seems to be bright, not only in Austria but throughout the world.

    Notes: Abstract Increased activity of the hypothalamic-pituitary-adrenocortical axis is part of the response to the stress of initial exposure to hypoxia, but there is evidence to suggest that it persists after homeostatic stability has been regained and acclimatization achieved. The adrenal glands of five lifelong residents of La Paz, Bolivia, who had lived at altitudes in the range 3600–3800 m, were significantly larger than those in age-matched controls from sea level (15.3g vs 10.4g;P〈0.001) and appeared hyperplastic. The pituitary glands of the highlanders were not significantly different in size from those of the controls (0.67 g vs 0.51 g), but contained larger populations of corticotrophs expressed in terms of the total cell population of their anterior lobes (25.6% vs 19.4%;P〈0.001). In conjunction with other studies of this endocrine axis in man and animals exposed to a hypoxic environment, these data suggest that greater amounts of adrenocorticotrophic hormone (ACTH) are required to maintain normal adrenocortical function under such circumstances, probably as a result of hypoxic inhibition of adrenocortical sensitivity to stimulation. Physiological hyperplasia of the adrenal cortex may be common in people living at high altitude.

    Notes: Abstract The development of the ecosystem concept illustrates the search for order in science and shows how individuals and the social-cultural environment of the science influence concept evolution. Ecosystem was coined in 1935 and replaced a variety of inappropriate terms which all referred to a system of biotic and inorganic interactions in nature. It was popularized after the second World War and became a dominant paradigm in ecology world wide. As such, it dominated the development of productivity studies within the International Biological Program. The ecosystem concept became mature when it was realized that the ecosystem was an object that could be studied directly, using conventional scientific methods. Currently the ecosystem concept exists along side a variety of ecological concepts which represent the guiding research foci of ecological subfields.

    Notes: Abstract A male weanling rabbit of the New Zealand White strain, born and living at an altitude of 3800 m in La Paz, Bolivia, developed right ventricular hypertrophy. This was found to be associated with growth of vascular smooth muscle cells in the intima of pulmonary arterioles, and contrasted with muscularization of the walls of pulmonary arterioles, without extension into the intima, found in a healthy, high-altitude control rabbit of the same strain. A low-altitude control showed no such muscularization. It is concluded that alveolar hypoxia, acting directly or through an intermediate agent, is a growth factor for vascular smooth muscle cells in pulmonary arterioles. This is the first report of pulmonary vascular disease due to high altitude in rabbits.

Factor analysis of correspondences and cluster analysis are used to classify the diatom assemblages. New methods are proposed to establish the qualitative and quantitative relationships between diatom floras and ecological parameters. Diatom assemblages are linked more to the ionic elements than to the salinity, pH, depth, temperature or elevation. Environmental variables are divided into three modalities which allow considerations of many different variables not under the same units.

    Notes: Abstract Critics of the computational connectionism of the last decade suggest that it shares undesirable features with earlier empiricist or associationist approaches, and with behaviourist theories of learning. To assess the accuracy of this charge the works of earlier writers are examined for the presence of such features, and brief accounts of those found are given for Herbert Spencer, William James and the learning theorists Thorndike, Pavlov and Hull. The idea that cognition depends on associative connections among large networks of neurons is indeed one with precedents, although the implications of this for psychological issues have been interpreted variously — not all versions of connectionism are alike.

    Notes: Abstract Some historical notes are presented on the start and early development of the Working-Group for Data-Processing, now Working-Group for Theoretical Vegetation Science, of the International Association for Vegetation Science. One of the major outcomes of the first period of activities in the Working-Group has been the creation of a phytosociological coding and retrieval system to be used in combination with multivariate methods. One branch of classical phytosociology which could have profited much from the Working-Group's achievements, i.e. syntaxonomy, never developed fully into a numerical syntaxonomy and, in fact, it did not develop much at all over the last 20 yr. The next phase in the development of the Working Group is characterized by a strong emphasis on vegetation dynamics. First, these dynamical studies concentrated on real sequences of data from permanent plots, which were treated with the numerical methods available. Later, dynamical models started to be developed in order to predict succession and other forms of long-term vegetation dynamics, for which real data are not available. The third phase, which has been entered only recently, is characterized by an overall emphasis on vegetation theory, from which both the most appropriate choice of numerical methods in any particular case, and dynamical phenomena can be approached. Moreover, vegetation theory is of fundamental importance for the development of the plant community concept and of vegetation typology. In addition, some remarks are made on the growing need for vegetation ecology to cooperate with experimental ecophysiology and population ecology.

    Notes: Abstract A definition of vegetation science is given, spanning 6 levels of integration and stressing the interrelations among them. The problems of realism are discussed. The selection of levels is related to the adequate correspondence between conceptualization and research aims. Pattern and process are introduced as the central concepts of vegetation science. The perception of reality is dependent on the spatial and temporal scale chosen. The concept of noise is discussed in relation to stochasticity and randomness of events. Traces of essentialism are found both in classification of communities and habitat ecology. Classification is important, particularly the coexistence of alternative classification approaches. Organicism as a basis of vegetation research is rejected because the organismic view is inadequate on higher integration levels. The concept of function is redefined in a non-teleologic way. Present vegetation ecological research is inductivistic. One possible alternative to inductivism is falsificationism. The major domain of this approach is hypothesis testing, which will become more important. Progress can only be reached by a maximum degree of communication among scientific individuals. Predictive ecology is partly based on historic explanation, partly on complementary approaches. Characters of vegetation worthwhile to be predicted are listed and the necessary requirements for vegetation science to become predictive are discussed. A major requirement is the development of succession and life-history theory. A further elaboration of the individualistic concept will be a main task of vegetation science in the near future.

    Notes: Abstract An index is presented of 375 articles which appeared in Vol. 51–73 of Vegetatio. A Source index is followed by a Keyword index, a Discipline index, a Vegetation type index, a Geographical index, and a Latin name index for taxa and syntaxa. The codes used for discipline, vegetation type and geographic area are the same as those used in the Index Vol. 1–50. After a short introduction a history of the journal is presented, followed by some statistics on the origin of the authors and the type of article, for seven periods covering the entire history of the journal since 1948. Finally the codes are elucidated.

    Notes: Synopsis It all started about 400 million years ago, when representatives of a group of fish-like fleshy-finned creatures appeared in the fossil record (or was it through a childhood dream shared by all of us that we would one day study the coelacanth?). Many of the coelacanth's characters placed them close to the ancestry of terrestrial vertebrates. About 70 million years ago they disappeared from the fossil record. The discovery in 1938 of the first living coelacanth, in 1952 of the second and until now over 200 specimens parallels in excitement an encounter with a live dinosaur on a weekend walk, and in significance even more than that. For this year's 50th anniversary of the famous discovery of the first living coelacanth, we retraced the routes and visited the main actors of this zoological drama. New insights into coelacanth natural history were facilitated by novel interpretation of earlier data and our expeditions to the Comoro Islands, retracing the route of the second specimen, measuring unrecorded specimens, interviewing fishermen and describing their fishing crafts, and taking part in recent events on land and water near the only known habitat of the living coelacanth. Entry into this habitat and observations from the research submersible GEO opened up a new era in coelacanth research. Past studies of preserved specimens, which were caught as an incidental bycatch, were supplemented for the first time by studies of free-living coelacanths in their natural habitat. The first film footage taken from the submersible revealed the entirely unfishlike movements of this creature. Its mode of locomotion is a combination of flying and gliding, interspersed with head stands and belly-up drifts which appear to defy gravity. The narrow range of habitat in which the coelacanth has been encountered has led us to realize how vulnerable this ancient relict is. The members of our expeditions therefore cooperated in establishing an international organisation to coordinate efforts to conserve the coelacanth.
