    Description: This document, which is directed at the fishing sector, researchers, conservationists and fishery administrators, was developed by researchers who are members of the Specialists Group for Marine Turtle Research and conservation in the Southwestern Atlantic Ocean (SWA) in response to the urgent need to evaluate the impact generated on sea turtles by fisheries. Historically, sea turtle conservation efforts have focused almost exclusively on the protection of nesting beaches. Nevertheless, over the last decade, research has proved incidental mortality as a result of fishing activities to be one of the greatest threats to these animals. This type of interaction is not only problematic for turtles, but also generates financial losses for fishermen and businesses. In spite of the efforts that are currently underway, researchers still do not have a detailed understanding of the impact that bycatch produces on sea turtle populations in the SWA. We have a long way to go before its effects can be minimized. Further research is needed regarding the biology and ecology of the various turtle species as well as the effective application of mitigation measures. The life cycles of sea turtles are long and complex. Turtles occupy various ecosystems (nesting beaches, coastal, neritic and oceanic zones, as well as pelagic and demersal areas) throughout their lifetimes, transcending various Exclusive Economic Zones and International Waters. The five species that inhabit the SWA region perform vast feeding and reproductive migrations, traveling through areas where many different fishing fleets operate. Therefore, sea turtles in the SWA interact with virtually all fisheries. These circumstances make it necessary to carry out biological, fishing related and conservation studies on a regional level. The efficiency of the existing international and national legal instruments has yet to be determined, in terms of their effectiveness in protecting sea turtles. In some cases, legislation that is specifically related to the interaction between fisheries and turtles does exist, such as those laws requiring the mandatory use of turtle excluding devices (TEDs). There are also explicit bans on sea turtle capture. Nevertheless, none of these regulations prevent sea turtle bycatch. Although some regional legal instruments are needed, these and the existing legislation will only be effective if they are accompanied by a broader range of permanent education and control measures, to achieve the commitment of all the parties involved. The ecosystem approach is gaining popularity among fishery administration organizations. Research and conservation efforts should also be moving in that direction. A regional and international effort is required in order to compile information regarding the bycatch produced by the various types of fisheries and fleets operating in the area. The enormous increase in fishing pressure that these fleets are exerting in this area has not been accompanied by an increase in information regarding the bycatch of species that have no commercial value. Pelagic longlining is one of the fishing methods, which must be most closely monitored, due to the high levels of bycatch that it produces, as well its ample distribution throughout the region, and the high level of fishing effort that it accounts for. Coastal trawlers and gillnetters must also be considered critical players, because they too produce a large rate of bycatch. These are the three types of fisheries that are most broadly distributed throughout the region, accounting for the majority of the fishing effort. Most of the institutions that work toward sea turtle conservation in the area have only begun to address the issue of bycatch over the last decade. This timeframe is reflected in the scope and quantity of the available publications, as well as the progress of activities directed at mitigating this problem. All of the institutions that have been mentioned in this report have made the gathering of information regarding interaction between sea turtles and fisheries one of their top priorities. Some institutions are even developing working programs for monitoring fisheries and testing mitigation measures. Many of these institutions have managed to develop adequate relationships with fishermen, ship owners and administrators. Nevertheless, limited access to funding is an obstacle to the development and testing of mitigation measures. The SWA network, which is a very valuable instrument that was created in 2003, has allowed the region’s institutions and researchers to exchange information and share their experience, in addition to lending each other support in carrying out joint activities, thus strengthening sea turtle conservation efforts. The capacity demonstrated so far by the region’s researchers and institutions, testifies to their ability to continue to make progress in knowledge generation and tests of bycatch mitigation measures.

    Description: Este documento, dirigido al sector pesquero, investigadores, conservacionistas y administradores de las pesquerías, surge como respuesta de investigadores pertenecientes al Grupo de Especialistas en Investigación y Conservación de Tortugas Marinas en el Atlántico Sud Occidental (ASO) a la urgente necesidad de evaluar el impacto de las pesquerías sobre las tortugas marinas. Históricamente, los esfuerzos referidos a la conservación de las tortugas marinas se han dirigido casi exclusivamente a proteger las playas de anidación. Sin embargo en la última década se ha podido comprobar que una de las mayores amenazas es la mortalidad incidental causada por las pesquerías. Esta interacción no implica únicamente un problema para las tortugas, sino que también genera pérdidas económicas para los pescadores y las empresas.

    Description: El presente trabajo llama la atención a las recientes epidemias de intoxicación histamínicas reportadas en los Estados Unidos, debido al consumo del dorado (Coryphaena hippurus) o Mahi-Mah, contaminado. Esto dió como resultado la prohición de las importaciones de esta especie, proveniente de varios países entre ellos el Ecuador, y siendo el dorado una especie de relativa importancia económica en este país, dicha prohibición ha preocupado al sector pesquero. Los estudios llevados a cabo muestran claramente la susceptibilidad de esta especie a desarrollar histamina. Esto se debe principalmente a la temperatura a la que está expuesta, pues la demora antes de enhielar el pescado es la etapa crítica. Los resultados muestran un aumento exponencial de los niveles de histamina, en ciertos casos después de tan solo 9 horas de almacenaje a temperaturas ambientales entre 25-30°C. Los niveles de histamina en pescado muestreado en el mercado local fueron tan altos como 250 mg/100g de muestra. Se demuestra que el problema se debe fundamentalmente al mal manejo de la captura por parte de la flota artesanal, y la subsecuente falta de infraestructura adecuada para conservarla, es decir, no se enfría el pescado. Sin embargo, el estudio muestra que una reducción de la temperatura del pescado de solo 15° menos, podría dar como resultado un producto de mayor calidad. En el presente trabajo se hacen recomendaciones para establecer un nivel máximo permitido para la exportación de 10 mg%, y se comparan dos métodos rápidos de análisis.

    Description: 153 experimental sets were made with stackable Antillean fish traps in depths of 5 to 30 m in the waters around the Galápagos Island (Ecuador), between Octobre and April 1983. 1,885 fish were caught of 18 species mainly of the families Pomadasyidae, Acanthuridae, Sparidae and Serranidae. The mean catch rate was 5,5 Kg per lift or 0,4 Kg.h-1, and the mean weight of the fish caught was 0,45 Kg. The optimum set duration was found to be between 2 and 18 hours (possibly indicating a high rate of escape). This study took place during the period of the ”El Niño”, when catches of fish in this area generally were low, and it is not known what effect this had. The catches were good compared with other shallow areas, but the fishes caught were mainly of medium quality. It is thought that significant increases in the quantity and quality of the catch could be obtained with commercial traps in deeper areas, but the efficient use of these would require new vessels and equipment, and the resulting increase in fishing effort could lead to overfishing of the most acceptable species of reef fish. Hence the development of fishery using fish traps is not recommended for Galápagos. A study of the biology of the fish caught was carried out. A bibliography of references on fish traps and their use was compiled and is included.

    Description: Le domaine maritime sénégalais s’étend de 18°00 N, -20°00 W, -16°30 E, 12°15 S ; la presqu’île du Cap-Vert située entre 14°30 N et 15°00 N le divise en deux zones aux caractéristiques topographiques distinctes. Au nord, le plateau continental est peu étendu vers le large et orienté Nord-Nord/Est. Au sud de la presqu’île, le plateau s’élargit et le talus continental est orienté nord-sud. L’embouchure du fleuve Sénégal au Sénégal au Nord de la presqu’île du Cap-Vert et celles de la Gambie et de la Casamance au Sud constituent également un trait marquant de cette région. Les travaux réalisés au Sénégal en océanographie ont montré : - l’existence de deux saisons marines aux caractéristiques très différentes qui se succèdent : une saison chaude de juillet à octobre et une saison froide de décembre à mai. Ces deux saisons sont séparées par des périodes de transition. Pendant la saison froide, les alizés (vent de secteur nord-ouest à nord-est) s’établissent et engendrent à la côte une résurgence d’eau profonde (upwelling) vers la surface ; - la mise en évidence de systèmes de grands courants aux caractéristiques différentes : le courant des Canaries et le contre courant équatorial ; - la description de trois grandes houles au large du Sénégal : o la houle de Nord-Nord ouest qui a lieu toute l’année o la houle de Sud-Sud ouest apparaissant pendant l’hivernage o la houle d’ouest possible aux environs du mois de novembre. Le littoral sénégalais représente une zone d’intérêt stratégique à la fois sur le plan démographique, économique et environnemental. Les milieux naturels, dans un état de conservation relativement préservé, produisent des ressources vitales pour les 11 millions d’habitants peuplant le Sénégal. L’économie nationale sénégalaise est très dépendante de ces ressources côtières et marines qui constituent les principales recettes en devises, qu’il s’agisse de pêche ou de tourisme. L’analyse de la situation et des tendances montre que la zone côtière fait l’objet de pressions diversifiées et de plus en plus lourdes. Ces pressions se traduisent souvent par des conflits d’intérêts entre les différents secteurs et par des impacts qui génèrent une dégradation de l’environnement et des conditions de vie des populations. Cette évolution risque ainsi de compromettre les potentialités de développement offertes par les 700 Km de littoral sénégalais. La pression démographique se développe préférentiellement sur la zone côtière qui accueille déjà près de 60% des habitants, notamment dans les centres urbains et les capitale, toutes situées en bord de mer, et qui continuent à recevoir des populations en provenance de l’intérieur, réfugiés climatiques ou économiques, ou simplement jeunesse attirée par les « lumières de la ville ». Cet exode, à l’origine de dysfonctionnements des systèmes de production ruraux qui manquent peu à peu de main d’oeuvre, contribue à son tour à générer des perturbations au niveau des centres urbains où la misère se substitue parfois à la pauvreté.
    Description: Les besoins en matériaux de construction consécutifs à cette évolution démographique entraînent des prélèvements massifs de sable sur les plages qui ont à leur tour des conséquences négatives sur l’érosion et la protection du littoral. La fragilisation des cordons dunaires augmente ainsi les risques d’inondations des terres, la ville de Saint Louis étant particulièrement vulnérable à cet égard. Les besoins en développement ont conduit à la réalisation d’infrastructures le long du littoral. Ces constructions, qui tiennent trop rarement compte des contraintes environnementales, ont entraîné des répercussions structurelles sur l’équilibre de la zone côtière. Ainsi, les barrages anti-sel, tel le barrage de Diama sur le fleuve Sénégal, ont entraîné des répercussions sur le fonctionnement de certains écosystèmes côtiers. En condamnant les influences des apports d’eau douce ils appauvrissent les milieux situés en aval, stérilisant peu à peu des zones riches en ressources ainsi que les économies et les cultures qui en dépendent. Le ralentissement des courants et la baisse de salinité en amont du barrage favorisent l’apparition de certaines plantes envahissantes, telles que la bilharziose ou le paludisme. Les effectifs de poissons dépendant de milieux à salinité variable sont directement affectés, expliquant par exemple une chute de près de 70% des captures dans le bas delta du Sénégal. Les besoins du développement se traduisent également par l’amélioration ou la création d’axes routiers qui, dans la majorité des cas, longent la zone côtière. Ces ouvrages entraînent des impacts directs sur l’environnement, tels la destruction des mangroves là où les routes barrent l’écoulement des marées (exemple de la route Samba Dia – Djifère. Les systèmes de production traditionnels sont en règle générale peu préparés à faire face à des circuits de commercialisation organisés à une échelle régionale ou internationale, où à des technologies plus performantes, et éprouvent des difficultés à maintenir un contrôle sur leur terroir. Faute de pouvoir opérer une métamorphose rapide de leur système de production, le risque existe de voir peu à peu disparaître des savoir-faire d’une grande valeur dans la gestion même de ces territoires et de leurs ressources et , plus généralement, des cultures qui leur sont associées. Le développement industriel exerce des impacts potentiels ou réels de grande magnitude sur la zone côtière et marine. Les secteurs les plus significatifs à cet égard sont le tourisme et les hydrocarbures. Concernant le premier, les infrastructures, principalement orientées vers le tourisme balnéaire, sont en grande majorité installées à proximité directe de la zone côtière. L’absence quasi généralisée d’études d’impacts approfondies et indépendantes a conduit à de nombreux échecs. Ainsi, la plupart des projets ont été pensés et réalisés sans tenir suffisamment compte des contextes socio-économiques, culturels et environnementaux dans lesquels ils s’insèrent. Certaines réalisations ont été planifiées sur des secteurs soumis à une forte érosion littorale, compromettant de façon irrémédiable non seulement les investissements mais l’utilisation ultérieure du site, comme cela s’est produit sur les plages au sud immédiat du Cap Skirring. Les questions relatives à la disponibilité en eau douce qui se posent de façon cruciale dans le Saloum par exemple, à la gestion des déchets et des eaux usées ne sont que rarement prises en considération de façon structurelle et durable, conduisant à la dégradation de l’environnement ou à des conflits avec les communautés locales qui nuisent à la qualité même du tourisme. L’exploration et l’exploitation des ressources en hydrocarbures représentent aussi un secteur d’intérêt stratégique avec une généralisation des prospections. Si la découverte de gisement d’intérêt commercial représente une opportunité majeure pour l’économie nationale, elle soulève néanmoins un certain nombre de questions au regard de l’environnement. En effet les des puits. Parmi ces risques nous pouvons citer les impacts des études sismiques sur les organismes marins, notamment poissons et cétacés, le rejet de fluides toxiques et déblais de forage, le déversement des eaux de production et les pollutions aiguës dues à des accidents intervenant pendant le forage, le stockage ou le transport. Le Sénégal en ce moment, en est au stade de la prospection. Toutefois, pour ce qui concerne le transport d’hydrocarbures, plus de 90 000 0000 de tonnes d’hydrocarbures transitent par les côtes sénégalaises. Les modèles de dérive des nappes élaborés par la Compagnie pétrolière Woodside en relation avec le champ de Chinguetti, actuellement en cours de production au large de la Mauritanie, montrent des probabilités d’impact sur les côtes allant du golfe d’Arguin jusqu’à Dakar, en cas d’accident. La surexploitation des ressources halieutiques constitue également un problème au niveau de l’environnement marin et côtier. En effet, si une partie de la fluctuation des biomasses peut s’expliquer par les changements du régime des upwellings, la baisse des captures s’explique par un effort de pêche excessif, que ce soit dans le sous-secteur industriel ou artisanal. A cette surcapacité vient s’ajouter la présence de flottes illicites non déclarées et non réglementées. L’utilisation de certains engins ou pratiques de pêche contribue à aggraver la situation : la pêche crevettière est à l’origine de prises accidentelles qui représentent jusqu’à 85 % du total des captures, incluant des espèces protégées comme les tortues marines, et qui sont rejetés à la mer . Les chaluts de fonds, qui vont pêcher jusqu’à 800 m de profondeur, ainsi que les dragues à coquillages entraînant des dégâts structurels sur les écosystèmes De plus l’influence des marchés à l’exportation exerce des pressions sélectives sur certaines espèces, les espèces démersales de poissons, céphalopodes étant les plus recherchées sur le marché. Les changements climatiques ont également des impacts négatifs sur l’environnement marin et côtier. On sait que l’élévation du niveau marin aura des répercussions directes sur les installations humaines littorales ainsi que sur les écosystèmes insulaires et côtiers. Des zones de mangroves entières qui ne disposent pas des conditions écologiques pour s’adapter peuvent disparaître, entraînant des risques accrus d’érosion et d’inondation. Ces mêmes risques se multiplient avec la fréquence accrue des épisodes météorologiques exceptionnels tels que les ondes de tempêtes capables de drosser les pirogues à la côte ou de provoquer la rupture de cordons dunaires. On sait par ailleurs que le réchauffement de la température des mers influe négativement sur la productivité des océans et la dynamique des courants tels que le courant profond originaire de l’antarctique et qui exporte vers le Sénégal et les autres pays de la sousrégion des sels nutritifs présents dans les upwellings. On observe également une diminution de la puissance des alizés qui pourrait avoir des répercussions directes sur la force des upwellings et donc sur la productivité des pêcheries et du milieu marin en général. La stratégie de réponse proposée combine une protection des zones côtières importantes et un reboisement des dunes littorales dans les secteurs de la côte nord et de la Flèche de Sangomar particulièrement menacés. L’évaluation économique de cette stratégie montre qu’elle est coûteuse mais nettement en deçà de la valeur économique des terres qu’elle sera amenée à protéger. Des efforts complémentaires devront cependant être faits pour évaluer le coût d’autres solutions de protection telles que le nourissement artificiel des plages. Par ailleurs, la stratégie envisagée ne répondant qu’à l’un des impacts des changements climatiques, à savoir les inondations, toute une série de mesures dites d’accompagnement ont été suggérées qui visent à diminuer la vulnérabilité en gérant mieux les ressources présentes dans la zone côtière, en développant les techniques de récupération des sols salés et en prenant des mesures législatives et institutionnelles appropriées. Enfin, il est très important de souligner que ces différentes mesures ne devraient être envisagées que dans un cadre plus global de gestion intégrée des zones côtières, seul à même d’assurer la participation de l’ensemble des acteurs concernés, l’éducation, la recherche et l’information environnementales mais aussi la cohérences et le suivi des mesures.

    Description: This paper examines the arrival of a new group of fishermen on the Kenyan coast and what this has meant for the state of fishery resources. It reviews four subject areas: access and the number of fishermen; the fishermen’s identity; the choice of fishing gear; and the fishing grounds selected. Data were collected from a small number of fishing households in the villages of Uyombo and Takaungu in Kilifi District, using mainly qualitative research methods. Local households on the Kenyan coast face increasing pressure on land as well as on marine resources. The declining economic situation and greater pressure on land have made people turn to fishing as an income-generating activity. This group of fishermen is referred to as the ‘new’ generation of fishermen as they have been involved in fishing for only one or two generations (including the current one) in contrast to the ‘old’ generation from families who have been fishing or in fishingrelated activities for much longer. The old generation of fishermen and their households have also diversified their incomes, with many fishing households turning to farming, for example, with women and grown-up children involved in various activities. The new generation of fishermen, mainly of the Mijikenda population group, has often been blamed for the loss of traditional access regulations and for using harmful fishing gear. This paper discusses the new generation of fishermen and their identity as they perceive it and relates this to employment generation as a policy measure for marine conservation.

    Description: L’étude porte sur l’évolution du pH et de la température au cours de la transformation artisanale du Cymbium, ainsi que sur les perspectives de valorisation du produit transformé. Les expérimentations menées au site de transformation artisanale de Joal ont permis de constater que : Après 12 heures de séjour en bac (1ère nuit), le Cymbium est encore en phase de rigor mortis. Le pH moyen affiché à l’issue de cette première nuit est de 7,6 ; donc proche de celui du mollusque vivant ; Le pH moyen du produit fini est légèrement acide et se situe entre 6,3 et 6,4. Donc le yeet de Joal est très peu fermenté ; Les difficultés de séchage notées sont dues : soit au manque de maîtrise des paramètres tels que, la température, l’humidité relative et la vitesse de l’air, soit à l’absence de protection du produit en cours de séchage contre les intempéries. Les essais sur les perspectives de valorisation montrent que : 47,64% du poids du Cymbium dépourvu de sa coquille font l’objet de rejets sous forme de rebuts (surtout en milieu industriel) ; Les enzymes végétales que sont, la bromélaïne, contenue dans le jus d’ananas, et la papaïne, contenue dans le latex de papaye, ainsi que les acides organiques contenus dans le vinaigre et le jus de citron, favorisent l’acidification et accélèrent la fermentation, tout en améliorant le goût, l’odeur et la texture du produit fini ; Les meilleurs résultats sont obtenus dans le cas de la fermentation sous température contrôlée, au laboratoire, où le pH du produit fini se situe entre 4,3 et 4,7. Enfin, sur l’ensemble de l’étude, il est prouvé que les rendements obtenus pour les produits ayant subi un processus de transformation complète (dans le cas des essais sur les perspectives de valorisation) sont faibles par rapport à ceux transformés à Joal. Ces rendements vont de : 2,88 à 28,57% pour le premier groupe de produits ct 31,4 à 58,3% pour le second groupe de produits.

    Description: Hominid fossils predating the emergence of Australopithecus have been sparse and fragmentary. The evolution of our lineage after the last common ancestor we shared with chimpanzees has therefore remained unclear. Ardipithecus ramidus, recovered in ecologically and temporally resolved contexts in Ethiopia's Afar Rift, now illuminates earlier hominid paleobiology and aspects of extant African ape evolution. More than 110 specimens recovered from 4.4-million-year-old sediments include a partial skeleton with much of the skull, hands, feet, limbs, and pelvis. This hominid combined arboreal palmigrade clambering and careful climbing with a form of terrestrial bipedality more primitive than that of Australopithecus. Ar. ramidus had a reduced canine/premolar complex and a little-derived cranial morphology and consumed a predominantly C3 plant-based diet (plants using the C3 photosynthetic pathway). Its ecological habitat appears to have been largely woodland-focused. Ar. ramidus lacks any characters typical of suspension, vertical climbing, or knuckle-walking. Ar. ramidus indicates that despite the genetic similarities of living humans and chimpanzees, the ancestor we last shared probably differed substantially from any extant African ape. Hominids and extant African apes have each become highly specialized through very different evolutionary pathways. This evidence also illuminates the origins of orthogrady, bipedality, ecology, diet, and social behavior in earliest Hominidae and helps to define the basal hominid adaptation, thereby accentuating the derived nature of Australopithecus.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, Tim D -- Asfaw, Berhane -- Beyene, Yonas -- Haile-Selassie, Yohannes -- Lovejoy, C Owen -- Suwa, Gen -- WoldeGabriel, Giday -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):75-86.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Evolution Research Center and Department of Integrative Biology, 3101 Valley Life Sciences Building, University of California, Berkeley, CA 94720, USA. timwhite@berkeley.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810190" target="_blank"〉PubMed〈/a〉

    Description: A diverse assemblage of large mammals is spatially and stratigraphically associated with Ardipithecus ramidus at Aramis. The most common species are tragelaphine antelope and colobine monkeys. Analyses of their postcranial remains situate them in a closed habitat. Assessment of dental mesowear, microwear, and stable isotopes from these and a wider range of abundant associated larger mammals indicates that the local habitat at Aramis was predominantly woodland. The Ar. ramidus enamel isotope values indicate a minimal C4 vegetation component in its diet (plants using the C4 photosynthetic pathway), which is consistent with predominantly forest/woodland feeding. Although the Early Pliocene Afar included a range of environments, and the local environment at Aramis and its vicinity ranged from forests to wooded grasslands, the integration of available physical and biological evidence establishes Ar. ramidus as a denizen of the closed habitats along this continuum.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉White, Tim D -- Ambrose, Stanley H -- Suwa, Gen -- Su, Denise F -- DeGusta, David -- Bernor, Raymond L -- Boisserie, Jean-Renaud -- Brunet, Michel -- Delson, Eric -- Frost, Stephen -- Garcia, Nuria -- Giaourtsakis, Ioannis X -- Haile-Selassie, Yohannes -- Howell, F Clark -- Lehmann, Thomas -- Likius, Andossa -- Pehlevan, Cesur -- Saegusa, Haruo -- Semprebon, Gina -- Teaford, Mark -- Vrba, Elisabeth -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):87-93.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Human Evolution Research Center and Department of Integrative Biology, 3101 Valley Life Sciences Building, University of California, Berkeley, CA 94720, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810193" target="_blank"〉PubMed〈/a〉

    Description: Like many species, the model plant Arabidopsis thaliana exhibits multiple different life histories in natural environments. We grew mutants impaired in different signaling pathways in field experiments across the species' native European range in order to dissect the mechanisms underlying this variation. Unexpectedly, mutational loss at loci implicated in the cold requirement for flowering had little effect on life history except in late-summer cohorts. A genetically informed photothermal model of progression toward flowering explained most of the observed variation and predicted an abrupt transition from autumn flowering to spring flowering in late-summer germinants. Environmental signals control the timing of this transition, creating a critical window of acute sensitivity to genetic and climatic change that may be common for seasonally regulated life history traits.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilczek, Amity M -- Roe, Judith L -- Knapp, Mary C -- Cooper, Martha D -- Lopez-Gallego, Cristina -- Martin, Laura J -- Muir, Christopher D -- Sim, Sheina -- Walker, Alexis -- Anderson, Jillian -- Egan, J Franklin -- Moyers, Brook T -- Petipas, Renee -- Giakountis, Antonis -- Charbit, Erika -- Coupland, George -- Welch, Stephen M -- Schmitt, Johanna -- New York, N.Y. -- Science. 2009 Feb 13;323(5916):930-4. doi: 10.1126/science.1165826.

    Description: Environmental perturbations during mass extinctions were likely manifested differently in epicontinental seas than in open-ocean-facing habitats of comparable depth. Here, we present a dissection of origination and extinction in epicontinental seas versus open-ocean-facing coastal regions in the Permian through Cretaceous periods, an interval through which both settings are well represented in the fossil record. Results demonstrate that extinction rates were significantly higher in open-ocean settings than in epicontinental seas during major mass extinctions but not at other times and that origination rates were significantly higher in open-ocean settings for a protracted interval from the Late Jurassic through the Late Cretaceous. These patterns are manifested even when other paleogeographic and environmental variables are held fixed, indicating that epicontinental seas and open-ocean-facing coastlines carry distinct macroevolutionary signatures.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Miller, Arnold I -- Foote, Michael -- New York, N.Y. -- Science. 2009 Nov 20;326(5956):1106-9. doi: 10.1126/science.1180061.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Geology, University of Cincinnati, Post Office Box 210013, Cincinnati, OH 45221, USA. arnold.miller@uc.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19965428" target="_blank"〉PubMed〈/a〉

    Description: Although mean rates of spread for invasive species have been intensively studied, variance in spread rates has been neglected. Variance in spread rates can be driven exogenously by environmental variability or endogenously by demographic or genetic stochasticity in reproduction, survival, and dispersal. Endogenous variability is likely to be important in spread but has not been studied empirically. We show that endogenously generated variance in spread rates is remarkably high between replicated invasions of the flour beetle Tribolium castaneum in laboratory microcosms. The observed variation between replicate invasions cannot be explained by demographic stochasticity alone, which indicates inherent limitations to predictability in even the simplest ecological settings.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Melbourne, Brett A -- Hastings, Alan -- New York, N.Y. -- Science. 2009 Sep 18;325(5947):1536-9. doi: 10.1126/science.1176138.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, CO 80309, USA. brett.melbourne@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19762641" target="_blank"〉PubMed〈/a〉

    Description: Sediments containing Ardipithecus ramidus were deposited 4.4 million years ago on an alluvial floodplain in Ethiopia's western Afar rift. The Lower Aramis Member hominid-bearing unit, now exposed across a 〉 9-kilometer structural arc, is sandwiched between two volcanic tuffs that have nearly identical 40Ar/39Ar ages. Geological data presented here, along with floral, invertebrate, and vertebrate paleontological and taphonomic evidence associated with the hominids, suggest that they occupied a wooded biotope over the western three-fourths of the paleotransect. Phytoliths and oxygen and carbon stable isotopes of pedogenic carbonates provide evidence of humid cool woodlands with a grassy substrate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉WoldeGabriel, Giday -- Ambrose, Stanley H -- Barboni, Doris -- Bonnefille, Raymonde -- Bremond, Laurent -- Currie, Brian -- DeGusta, David -- Hart, William K -- Murray, Alison M -- Renne, Paul R -- Jolly-Saad, M C -- Stewart, Kathlyn M -- White, Tim D -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):65e1-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Earth Environmental Sciences Division, Los Alamos National Laboratory, Los Alamos, NM 87545, USA. wgiday@lanl.gov〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810191" target="_blank"〉PubMed〈/a〉

    Description: Thousands of vertebrate specimens were systematically collected from the stratigraphic interval containing Ardipithecus ramidus. The carcasses of larger mammals were heavily ravaged by carnivores. Nearly 10,000 small-mammal remains appear to be derived primarily from decomposed owl pellets. The rich avifauna includes at least 29 species, mostly nonaquatic forms. Modern analogs of the most abundant birds and of a variety of rodents are associated with mesic woodland environments distant from large water bodies. These findings support inferences from associated geological, isotopic, invertebrate, and large-vertebrate assemblages. The combined results suggest that Ar. ramidus occupied a wooded Pliocene habitat.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Louchart, Antoine -- Wesselman, Henry -- Blumenschine, Robert J -- Hlusko, Leslea J -- Njau, Jackson K -- Black, Michael T -- Asnake, Mesfin -- White, Tim D -- New York, N.Y. -- Science. 2009 Oct 2;326(5949):66e1-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Iziko South African Museum, Natural History Department, Cenozoic Palaeontology Collections, Box 61, Cape Town 8000, South Africa.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19810192" target="_blank"〉PubMed〈/a〉

    Description: La creciente importancia que los recursos de calamar han adquirido en 105 últimos 30 años, los sitúa actualmente entre los más importantes recursos pesqueros del mundo. En consecuencia, paises tradicionalmente no explotadores o consumidores de productos de calamar, han orientado sus esfuerzos hacia el logro de un mejor conocimiento de las especies de cefalópodos que habitan su ambiente marino. En este sentido el aporte de disciplinas tales como la biología ha sido decisivo para desarrollar en forma exitosa pesquerías de calamar, entre otras.El programa de investigaciones del Instituto Nacional de Pesca para 1980 incluyó el estudio integral de la explotación de los calamares como un primer paso hacia el desarrollo de una pesquería del recurso. Este trabajo presenta los resultados de un estudio de los aspectos biológicos de la especie más importante del área: Illex argentinus y forma parte de una serie de tres documentos técnicos escritos por el autor referentes a recursos de calamar. Dichos documentos están relacionados con la tecnología de captura y la producción y comercialización del calamar en el Uruguay.
    Description: The growing importance of the squid resources during the last 30 years place them among the more important fish resources of the world. Therefore countries traditional1y non exploiters or consumers of squid products gave steps toward a better knowledge of the species of cephalopods inhabiting their marine environment. For instance, the contribution of subjects such as the biology lead to a successful development of squid fisheries, among others. The 1980 research program of the National Fisheries Institute included an integral study of the exploitation of the squids as a first step toward the development of a squid fishery. This paper presents the results of a study on the biological aspects of the principal species of the area: Illex argentinus. It is part of three technical reports written by the author on squid resources. These reports are fishery technology and production & marketing of squids in Uruguay.

    Description: Durante las últimas décadas se ha observado un incremento de la captura (descartada y retenida) de condrictios en las pesquerías artesanales e industriales, conjuntamente con un rápido crecimiento de las pesquerías no reguladas, lo cual ha ocasionado una disminución en muchas poblaciones de este grupo de peces en todos los mares del mundo. La sobrepesca y los elevados niveles de mortalidad ocasionados por la captura incidental, asi como la degradación y contaminación de áreas costeras donde se ubican las zonas de alimentación, reproducción y cría para muchas especies de condrictios, han colocado a este grupo de peces en una situación difícil. Estos hechos, combinados con el bajo potencial reproductivo y la estrategia de vida de la mayoría de las especies de condríctios, no permiten una recuperación de las poblaciones, cuando las mismas se ven enfrentadas a períodos de sobreexplotación. En las aguas de Uruguay ocurren aproximadamente 100 especies de condrictios, muchas de las cuales son capturadas por diferentes pesquerias, tanto de forma incidental como dirigida. Debido a la preocupación a nivel internacional sobre la sustentabilidad de las pesquerías de tiburones, la FAO en 1998 realizó una consulta internacional a expertos y desarrolló un “Plan de Acción Internacional para la Conservación y el Manejo de los Tiburones” (PAI - Tiburones), el cual fue adoptado en 1999. El objetivo del PAI - Tiburones es asegurar la conservación, el manejo y el uso sustentable a largo plazo de los tiburones. Al hacer referencia a “tiburones”, se incluyen a todos los condrictios (tiburones, batoideos y quimeras). Este documento se divide en dos Capítulos y cuatro Anexos. El primer capítulo incluye los objetivos del PAN - Condrictios Uruguay y las medidas propuestas para alcanzar los mismos. El segundo capítulo contiene un diagnóstico general de los condrictios, las pesquerías y el marco jurídico. Como anexos se incluyen una lista de especies de condrictios citadas para Uruguay junto a su status en las listas rojas de la UICN, una reseña biológica de las especies consideradas prioritaras, una lista de abreviaturas, y listas de instituciones y personas que participaron de las reuniones desarrolladas durante el proceso de elaboración del PAN – Condrictios Uruguay. Las medidas propuestas por el PAN - Condrictios Uruguay se deberán aplicar a todas las pesquerías efectuadas por buques de bandera uruguaya, incluso los que operan fuera de la zona económica exclusiva de Uruguay.

    Description: La captura incidental en pesquerías comerciales ha sido identificada como una de las principales amenazas para la conservación de este grupo de aves, siendo los albatros (familia: Diomedeidae) y los petreles (familia: Procellariidae) las especies más afectadas. Debido a que los albatros y petreles presentan una gran longevidad y una baja fecundidad, pocas crías y un lento desarrollo, sus poblaciones son muy sensibles al aumento en la tasa de mortalidad causado por la captura incidental en las pesquerías. Anualmente son capturadas y muertas miles de aves marinas en las pesquerías comerciales que operan con diferentes configuraciones de palangre alrededor del mundo. Este arte, entre otras causas, está contribuyendo al descenso de varias poblaciones de albatros y preteles, configurando un claro riesgo de extinción de estas especies, si se permite que las tendencias actuales persistan. Las pesquerías de arrastre también interactúan con las aves marinas provocando la mortalidad de las mismas en un importante número. Otras pesquerías que capturan aves marinas son las que operan con redes de enmalle, redes de cerco y poteras. Respondiendo a la necesidad de reducir la mortalidad de aves marinas la Organización de las Naciones Unidas para la Agricultura y la Alimentación (FAO) desarrolló un Plan de Acción Internacional para Reducir la Captura Incidental de Aves Marinas en las Pesquerías de Palangre, el cual propicia la elaboración de Planes de Acción Nacionales en cada uno de sus países miembros. El objetivo del Plan de Acción Nacional – Aves Marinas de Uruguay es presentar un marco general que permita instrumentar medidas para la reducción de la captura incidental de aves marinas en todas las pesquerías de Uruguay.

    Description: In this study, we develop a framework for measuring the value of harmful algal bloom (HAB) predictions. The framework captures the effects of both private and public responses to HABs. Using data from the New England nearshore commercial shellfish fishery and impact estimates for a large-scale HAB event in 2005, we illustrate how the potential value of HAB forecasts may be estimated. The results of our study suggest that the long-term value of a HAB prediction and tracking system for the Gulf of Maine is sensitive to the frequency of HAB events, the accuracy of predictions, the choice of HAB impact measures, and the effectiveness of public and private responses.

    Description: Emerging infectious diseases (EIDs) are a significant burden on global economies and public health. Their emergence is thought to be driven largely by socio-economic, environmental and ecological factors, but no comparative study has explicitly analysed these linkages to understand global temporal and spatial patterns of EIDs. Here we analyse a database of 335 EID 'events' (origins of EIDs) between 1940 and 2004, and demonstrate non-random global patterns. EID events have risen significantly over time after controlling for reporting bias, with their peak incidence (in the 1980s) concomitant with the HIV pandemic. EID events are dominated by zoonoses (60.3% of EIDs): the majority of these (71.8%) originate in wildlife (for example, severe acute respiratory virus, Ebola virus), and are increasing significantly over time. We find that 54.3% of EID events are caused by bacteria or rickettsia, reflecting a large number of drug-resistant microbes in our database. Our results confirm that EID origins are significantly correlated with socio-economic, environmental and ecological factors, and provide a basis for identifying regions where new EIDs are most likely to originate (emerging disease 'hotspots'). They also reveal a substantial risk of wildlife zoonotic and vector-borne EIDs originating at lower latitudes where reporting effort is low. We conclude that global resources to counter disease emergence are poorly allocated, with the majority of the scientific and surveillance effort focused on countries from where the next important EID is least likely to originate.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Jones, Kate E -- Patel, Nikkita G -- Levy, Marc A -- Storeygard, Adam -- Balk, Deborah -- Gittleman, John L -- Daszak, Peter -- R01 AI079231/AI/NIAID NIH HHS/ -- R01 TW005869/TW/FIC NIH HHS/ -- T32 HD007338/HD/NICHD NIH HHS/ -- England -- Nature. 2008 Feb 21;451(7181):990-3. doi: 10.1038/nature06536.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Zoology, Zoological Society of London, Regents Park, London NW1 4RY, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18288193" target="_blank"〉PubMed〈/a〉

    Description: Extinction risk in natural populations depends on stochastic factors that affect individuals, and is estimated by incorporating such factors into stochastic models. Stochasticity can be divided into four categories, which include the probabilistic nature of birth and death at the level of individuals (demographic stochasticity), variation in population-level birth and death rates among times or locations (environmental stochasticity), the sex of individuals and variation in vital rates among individuals within a population (demographic heterogeneity). Mechanistic stochastic models that include all of these factors have not previously been developed to examine their combined effects on extinction risk. Here we derive a family of stochastic Ricker models using different combinations of all these stochastic factors, and show that extinction risk depends strongly on the combination of factors that contribute to stochasticity. Furthermore, we show that only with the full stochastic model can the relative importance of environmental and demographic variability, and therefore extinction risk, be correctly determined. Using the full model, we find that demographic sources of stochasticity are the prominent cause of variability in a laboratory population of Tribolium castaneum (red flour beetle), whereas using only the standard simpler models would lead to the erroneous conclusion that environmental variability dominates. Our results demonstrate that current estimates of extinction risk for natural populations could be greatly underestimated because variability has been mistakenly attributed to the environment rather than the demographic factors described here that entail much higher extinction risk for the same variability level.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Melbourne, Brett A -- Hastings, Alan -- England -- Nature. 2008 Jul 3;454(7200):100-3. doi: 10.1038/nature06922.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Ecology and Evolutionary Biology, University of Colorado, Boulder, Colorado 80309, USA. brett.melbourne@colorado.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18596809" target="_blank"〉PubMed〈/a〉

    Description: Stomatal pores, formed by two surrounding guard cells in the epidermis of plant leaves, allow influx of atmospheric carbon dioxide in exchange for transpirational water loss. Stomata also restrict the entry of ozone--an important air pollutant that has an increasingly negative impact on crop yields, and thus global carbon fixation and climate change. The aperture of stomatal pores is regulated by the transport of osmotically active ions and metabolites across guard cell membranes. Despite the vital role of guard cells in controlling plant water loss, ozone sensitivity and CO2 supply, the genes encoding some of the main regulators of stomatal movements remain unknown. It has been proposed that guard cell anion channels function as important regulators of stomatal closure and are essential in mediating stomatal responses to physiological and stress stimuli. However, the genes encoding membrane proteins that mediate guard cell anion efflux have not yet been identified. Here we report the mapping and characterization of an ozone-sensitive Arabidopsis thaliana mutant, slac1. We show that SLAC1 (SLOW ANION CHANNEL-ASSOCIATED 1) is preferentially expressed in guard cells and encodes a distant homologue of fungal and bacterial dicarboxylate/malic acid transport proteins. The plasma membrane protein SLAC1 is essential for stomatal closure in response to CO2, abscisic acid, ozone, light/dark transitions, humidity change, calcium ions, hydrogen peroxide and nitric oxide. Mutations in SLAC1 impair slow (S-type) anion channel currents that are activated by cytosolic Ca2+ and abscisic acid, but do not affect rapid (R-type) anion channel currents or Ca2+ channel function. A low homology of SLAC1 to bacterial and fungal organic acid transport proteins, and the permeability of S-type anion channels to malate suggest a vital role for SLAC1 in the function of S-type anion channels.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2858982/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2858982/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vahisalu, Triin -- Kollist, Hannes -- Wang, Yong-Fei -- Nishimura, Noriyuki -- Chan, Wai-Yin -- Valerio, Gabriel -- Lamminmaki, Airi -- Brosche, Mikael -- Moldau, Heino -- Desikan, Radhika -- Schroeder, Julian I -- Kangasjarvi, Jaakko -- P42 ES010337/ES/NIEHS NIH HHS/ -- P42 ES010337-070008/ES/NIEHS NIH HHS/ -- R01 GM060396/GM/NIGMS NIH HHS/ -- R01 GM060396-07/GM/NIGMS NIH HHS/ -- England -- Nature. 2008 Mar 27;452(7186):487-91. doi: 10.1038/nature06608.

    Description: The human distal gut harbours a vast ensemble of microbes (the microbiota) that provide important metabolic capabilities, including the ability to extract energy from otherwise indigestible dietary polysaccharides. Studies of a few unrelated, healthy adults have revealed substantial diversity in their gut communities, as measured by sequencing 16S rRNA genes, yet how this diversity relates to function and to the rest of the genes in the collective genomes of the microbiota (the gut microbiome) remains obscure. Studies of lean and obese mice suggest that the gut microbiota affects energy balance by influencing the efficiency of calorie harvest from the diet, and how this harvested energy is used and stored. Here we characterize the faecal microbial communities of adult female monozygotic and dizygotic twin pairs concordant for leanness or obesity, and their mothers, to address how host genotype, environmental exposure and host adiposity influence the gut microbiome. Analysis of 154 individuals yielded 9,920 near full-length and 1,937,461 partial bacterial 16S rRNA sequences, plus 2.14 gigabases from their microbiomes. The results reveal that the human gut microbiome is shared among family members, but that each person's gut microbial community varies in the specific bacterial lineages present, with a comparable degree of co-variation between adult monozygotic and dizygotic twin pairs. However, there was a wide array of shared microbial genes among sampled individuals, comprising an extensive, identifiable 'core microbiome' at the gene, rather than at the organismal lineage, level. Obesity is associated with phylum-level changes in the microbiota, reduced bacterial diversity and altered representation of bacterial genes and metabolic pathways. These results demonstrate that a diversity of organismal assemblages can nonetheless yield a core microbiome at a functional level, and that deviations from this core are associated with different physiological states (obese compared with lean).〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2677729/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2677729/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Turnbaugh, Peter J -- Hamady, Micah -- Yatsunenko, Tanya -- Cantarel, Brandi L -- Duncan, Alexis -- Ley, Ruth E -- Sogin, Mitchell L -- Jones, William J -- Roe, Bruce A -- Affourtit, Jason P -- Egholm, Michael -- Henrissat, Bernard -- Heath, Andrew C -- Knight, Rob -- Gordon, Jeffrey I -- AA09022/AA/NIAAA NIH HHS/ -- DK78669/DK/NIDDK NIH HHS/ -- ES012742/ES/NIEHS NIH HHS/ -- HD049024/HD/NICHD NIH HHS/ -- P01 DK078669/DK/NIDDK NIH HHS/ -- P01 DK078669-01/DK/NIDDK NIH HHS/ -- P30 DK056341/DK/NIDDK NIH HHS/ -- P30 DK056341-07/DK/NIDDK NIH HHS/ -- P30 DK056341-08/DK/NIDDK NIH HHS/ -- P50 ES012742/ES/NIEHS NIH HHS/ -- P50 ES012742-049001/ES/NIEHS NIH HHS/ -- R01 AA009022/AA/NIAAA NIH HHS/ -- R01 AA009022-10/AA/NIAAA NIH HHS/ -- R01 HD049024/HD/NICHD NIH HHS/ -- R01 HD049024-01/HD/NICHD NIH HHS/ -- T32 GM065103/GM/NIGMS NIH HHS/ -- T32 GM065103-07/GM/NIGMS NIH HHS/ -- UL1 TR000448/TR/NCATS NIH HHS/ -- England -- Nature. 2009 Jan 22;457(7228):480-4. doi: 10.1038/nature07540.

    Description: The biogeographic variation of life has predominantly been studied using taxonomy, but this focus is changing. There is a resurging interest in understanding patterns in the distribution not only of taxa but also of the traits those taxa possess. Patterns of trait variation shed light on fundamental questions in biology, including why organisms live where they do and how they will respond to environmental change. Technological advances such as environmental genomics place microbial ecology in a unique position to move trait-based biogeography forward. We anticipate that as trait-based biogeography continues to evolve, micro- and macroorganisms will be studied in concert, establishing a science that is informed by and relevant to all domains of life.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Green, Jessica L -- Bohannan, Brendan J M -- Whitaker, Rachel J -- New York, N.Y. -- Science. 2008 May 23;320(5879):1039-43. doi: 10.1126/science.1153475.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for Ecology and Evolutionary Biology, Department of Biology, University of Oregon, Eugene, Oregon 97403, USA. jlgreen@uoregon.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18497288" target="_blank"〉PubMed〈/a〉

    Description: The management and conservation of the world's oceans require synthesis of spatial data on the distribution and intensity of human activities and the overlap of their impacts on marine ecosystems. We developed an ecosystem-specific, multiscale spatial model to synthesize 17 global data sets of anthropogenic drivers of ecological change for 20 marine ecosystems. Our analysis indicates that no area is unaffected by human influence and that a large fraction (41%) is strongly affected by multiple drivers. However, large areas of relatively little human impact remain, particularly near the poles. The analytical process and resulting maps provide flexible tools for regional and global efforts to allocate conservation resources; to implement ecosystem-based management; and to inform marine spatial planning, education, and basic research.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Halpern, Benjamin S -- Walbridge, Shaun -- Selkoe, Kimberly A -- Kappel, Carrie V -- Micheli, Fiorenza -- D'Agrosa, Caterina -- Bruno, John F -- Casey, Kenneth S -- Ebert, Colin -- Fox, Helen E -- Fujita, Rod -- Heinemann, Dennis -- Lenihan, Hunter S -- Madin, Elizabeth M P -- Perry, Matthew T -- Selig, Elizabeth R -- Spalding, Mark -- Steneck, Robert -- Watson, Reg -- New York, N.Y. -- Science. 2008 Feb 15;319(5865):948-52. doi: 10.1126/science.1149345.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, 735 State Street, Santa Barbara, CA 93101, USA. halpern@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18276889" target="_blank"〉PubMed〈/a〉

    Description: It has previously been thought that there was a steep Cretaceous and Cenozoic radiation of marine invertebrates. This pattern can be replicated with a new data set of fossil occurrences representing 3.5 million specimens, but only when older analytical protocols are used. Moreover, analyses that employ sampling standardization and more robust counting methods show a modest rise in diversity with no clear trend after the mid-Cretaceous. Globally, locally, and at both high and low latitudes, diversity was less than twice as high in the Neogene as in the mid-Paleozoic. The ratio of global to local richness has changed little, and a latitudinal diversity gradient was present in the early Paleozoic.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Alroy, John -- Aberhan, Martin -- Bottjer, David J -- Foote, Michael -- Fursich, Franz T -- Harries, Peter J -- Hendy, Austin J W -- Holland, Steven M -- Ivany, Linda C -- Kiessling, Wolfgang -- Kosnik, Matthew A -- Marshall, Charles R -- McGowan, Alistair J -- Miller, Arnold I -- Olszewski, Thomas D -- Patzkowsky, Mark E -- Peters, Shanan E -- Villier, Loic -- Wagner, Peter J -- Bonuso, Nicole -- Borkow, Philip S -- Brenneis, Benjamin -- Clapham, Matthew E -- Fall, Leigh M -- Ferguson, Chad A -- Hanson, Victoria L -- Krug, Andrew Z -- Layou, Karen M -- Leckey, Erin H -- Nurnberg, Sabine -- Powers, Catherine M -- Sessa, Jocelyn A -- Simpson, Carl -- Tomasovych, Adam -- Visaggi, Christy C -- New York, N.Y. -- Science. 2008 Jul 4;321(5885):97-100. doi: 10.1126/science.1156963.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉National Center for Ecological Analysis and Synthesis, University of California-Santa Barbara, 735 State Street, Santa Barbara, CA 93101, USA. alroy@nceas.ucsb.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18599780" target="_blank"〉PubMed〈/a〉

    Description: Minerals are more complex than previously thought because of the discovery that their chemical properties vary as a function of particle size when smaller, in at least one dimension, than a few nanometers, to perhaps as much as several tens of nanometers. These variations are most likely due, at least in part, to differences in surface and near-surface atomic structure, as well as crystal shape and surface topography as a function of size in this smallest of size regimes. It has now been established that these variations may make a difference in important geochemical and biogeochemical reactions and kinetics. This recognition is broadening and enriching our view of how minerals influence the hydrosphere, pedosphere, biosphere, and atmosphere.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Hochella, Michael F Jr -- Lower, Steven K -- Maurice, Patricia A -- Penn, R Lee -- Sahai, Nita -- Sparks, Donald L -- Twining, Benjamin S -- New York, N.Y. -- Science. 2008 Mar 21;319(5870):1631-5. doi: 10.1126/science.1141134.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Center for NanoBioEarth, Department of Geosciences, Virginia Polytechnic Institute and State University (Virginia Tech), Blacksburg, VA 24061-0420, USA. hochella@vt.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18356515" target="_blank"〉PubMed〈/a〉

    Description: Studies suggest that populations of different species do not decline equally after habitat loss. However, empirical tests have been confined to fine spatiotemporal scales and have rarely included plants. Using data from 89,365 forest survey plots covering peninsular Spain, we explored, for each of 34 common tree species, the relationship between probability of occurrence and the local cover of remaining forest. Twenty-four species showed a significant negative response to forest loss, so that decreased forest cover had a negative effect on tree diversity, but the responses of individual species were highly variable. Animal-dispersed species were less vulnerable to forest loss, with six showing positive responses to decreased forest cover. The results imply that plant-animal interactions help prevent the collapse of forest communities that suffer habitat destruction.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Montoya, Daniel -- Zavala, Miguel A -- Rodriguez, Miguel A -- Purves, Drew W -- New York, N.Y. -- Science. 2008 Jun 13;320(5882):1502-4. doi: 10.1126/science.1158404.

    Description: What genes and regulatory sequences contribute to the organization and functioning of neural circuits and molecular pathways in the brain that support social behavior? How does social experience interact with information in the genome to modulate brain activity? Here, we address these questions by highlighting progress that has been made in identifying and understanding two key "vectors of influence" that link genes, the brain, and social behavior: (i) Social information alters gene expression in the brain to influence behavior, and (ii) genetic variation influences brain function and social behavior. We also discuss how evolutionary changes in genomic elements influence social behavior and outline prospects for a systems biology of social behavior.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3052688/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3052688/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Robinson, Gene E -- Fernald, Russell D -- Clayton, David F -- NS045264/NS/NINDS NIH HHS/ -- NS34950/NS/NINDS NIH HHS/ -- R01 GM073644/GM/NIGMS NIH HHS/ -- R01 GM073644-01A1/GM/NIGMS NIH HHS/ -- R01 NS034950/NS/NINDS NIH HHS/ -- R01 NS034950-16A2/NS/NINDS NIH HHS/ -- R01 NS045264/NS/NINDS NIH HHS/ -- R01 NS045264-01/NS/NINDS NIH HHS/ -- R01 NS051820/NS/NINDS NIH HHS/ -- R01 NS051820-10A1/NS/NINDS NIH HHS/ -- New York, N.Y. -- Science. 2008 Nov 7;322(5903):896-900. doi: 10.1126/science.1159277.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, University of Illinois at Urbana-Champaign, 505 South Goodwin Avenue, Urbana, IL 61801, USA. generobi@illinois.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18988841" target="_blank"〉PubMed〈/a〉

    Description: Atlantic bluefin tuna populations are in steep decline, and an improved understanding of connectivity between individuals from eastern (Mediterranean Sea) and western (Gulf of Mexico) spawning areas is needed to manage remaining fisheries. Chemical signatures in the otoliths of yearlings from regional nurseries were distinct and served as natural tags to assess natal homing and mixing. Adults showed high rates of natal homing to both eastern and western spawning areas. Trans-Atlantic movement (east to west) was significant and size-dependent, with individuals of Mediterranean origin mixing with the western population in the U.S. Atlantic. The largest (oldest) bluefin tuna collected near the northern extent of their range in North American waters were almost exclusively of western origin, indicating that this region represents critical habitat for the western population.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Rooker, Jay R -- Secor, David H -- De Metrio, Gregorio -- Schloesser, Ryan -- Block, Barbara A -- Neilson, John D -- New York, N.Y. -- Science. 2008 Oct 31;322(5902):742-4. doi: 10.1126/science.1161473.

    Description: Imagine that the neighborhood you are living in is covered with graffiti, litter, and unreturned shopping carts. Would this reality cause you to litter more, trespass, or even steal? A thesis known as the broken windows theory suggests that signs of disorderly and petty criminal behavior trigger more disorderly and petty criminal behavior, thus causing the behavior to spread. This may cause neighborhoods to decay and the quality of life of its inhabitants to deteriorate. For a city government, this may be a vital policy issue. But does disorder really spread in neighborhoods? So far there has not been strong empirical support, and it is not clear what constitutes disorder and what may make it spread. We generated hypotheses about the spread of disorder and tested them in six field experiments. We found that, when people observe that others violated a certain social norm or legitimate rule, they are more likely to violate other norms or rules, which causes disorder to spread.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Keizer, Kees -- Lindenberg, Siegwart -- Steg, Linda -- New York, N.Y. -- Science. 2008 Dec 12;322(5908):1681-5. doi: 10.1126/science.1161405.

    Description: Most prior studies have found that substituting biofuels for gasoline will reduce greenhouse gases because biofuels sequester carbon through the growth of the feedstock. These analyses have failed to count the carbon emissions that occur as farmers worldwide respond to higher prices and convert forest and grassland to new cropland to replace the grain (or cropland) diverted to biofuels. By using a worldwide agricultural model to estimate emissions from land-use change, we found that corn-based ethanol, instead of producing a 20% savings, nearly doubles greenhouse emissions over 30 years and increases greenhouse gases for 167 years. Biofuels from switchgrass, if grown on U.S. corn lands, increase emissions by 50%. This result raises concerns about large biofuel mandates and highlights the value of using waste products.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Searchinger, Timothy -- Heimlich, Ralph -- Houghton, R A -- Dong, Fengxia -- Elobeid, Amani -- Fabiosa, Jacinto -- Tokgoz, Simla -- Hayes, Dermot -- Yu, Tun-Hsiang -- New York, N.Y. -- Science. 2008 Feb 29;319(5867):1238-40. doi: 10.1126/science.1151861.

    Description: Analyses of the KNM-WT 15000 Homo erectus juvenile male partial skeleton from Kenya concluded that this species had a tall thin body shape due to specialized locomotor and climatic adaptations. Moreover, it was concluded that H. erectus pelves were obstetrically restricted to birthing a small-brained altricial neonate. Here we describe a nearly complete early Pleistocene adult female H. erectus pelvis from the Busidima Formation of Gona, Afar, Ethiopia. This obstetrically capacious pelvis demonstrates that pelvic shape in H. erectus was evolving in response to increasing fetal brain size. This pelvis indicates that neither adaptations to tropical environments nor endurance running were primary selective factors in determining pelvis morphology in H. erectus during the early Pleistocene.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Simpson, Scott W -- Quade, Jay -- Levin, Naomi E -- Butler, Robert -- Dupont-Nivet, Guillaume -- Everett, Melanie -- Semaw, Sileshi -- New York, N.Y. -- Science. 2008 Nov 14;322(5904):1089-92. doi: 10.1126/science.1163592.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Anatomy, Case Western Reserve University School of Medicine, Cleveland, OH 44106-4930, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/19008443" target="_blank"〉PubMed〈/a〉

    Description: Spatial fingerprints of climate change on biotic communities are usually associated with changes in the distribution of species at their latitudinal or altitudinal extremes. By comparing the altitudinal distribution of 171 forest plant species between 1905 and 1985 and 1986 and 2005 along the entire elevation range (0 to 2600 meters above sea level) in west Europe, we show that climate warming has resulted in a significant upward shift in species optimum elevation averaging 29 meters per decade. The shift is larger for species restricted to mountain habitats and for grassy species, which are characterized by faster population turnover. Our study shows that climate change affects the spatial core of the distributional range of plant species, in addition to their distributional margins, as previously reported.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Lenoir, J -- Gegout, J C -- Marquet, P A -- de Ruffray, P -- Brisse, H -- New York, N.Y. -- Science. 2008 Jun 27;320(5884):1768-71. doi: 10.1126/science.1156831.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉AgroParisTech, UMR 1092, Laboratoire d'Etude des Ressources Foret-Bois (LERFoB), 14 rue Girardet, F-54000 Nancy, France. jonathan.lenoir@agroparistech.fr〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18583610" target="_blank"〉PubMed〈/a〉

    Description: The exploitation status of cardinalfish (Epigonus crassicaudus) yielded in Chile between 33° to 41°S was analyzed. An indirect assessment was performed between 1997 and 2003 through size-structured model with a transition matrix defining the changes among sizes. The model was calibrated using size structures, official landings, catch-per-unit of effort (CPUE) taken from commercial fishing logbooks and standardized by generalized linear models (GLM). After 7 years of an intense fishery activity, we concluded that the cardinalfish resource in Chile is on the recruitment overfishing limit. On 2003, the spawning biomass with respect to the virginal spawning biomass is close to 40%. The biological references points (BRP) based on spawning per recruit biomass (SPR) support this assesment because the fishing mortality level on 2003 (Fact) was very close to fishing mortality level of 40% of SRP at virginal value (F40%).

    Description: The first year of the New England Regional Fisheries Management Council has been marked by its experimental aura. Neither the Council nor the various sectors (representatives of the Federal and State agencies, members of the fishing industry, the public at large) were clear as to exactly what they were to do and how they were to do it--except in the broadest, most flexible (ambiguous?) terms. This created certain operational difficulties, and confusion for those whose livelihood was affected by the Council's operation. This latter group, particularly the fishermen, knew little of what went on, save in terms of the 'public facet of the Council--i.e., that portion of the Council's performance which occurred during the monthly meetings which were open to the public and which, supposedly, received public input at that time. This study defines that public face, deliberately avoiding the presentation of any data which was not accessible to the average audience participant, in an attempt to present some of the behavior which all participants demonstrated and which generated responses and reactions on the part of the other sectors. It uses standard anthropological techniques of data gathering and analysis to show the degree to which impression management on the part of all the actors operated in a systematic fashion to produce action, reaction, and counter-action. Particularly emphasized is the communication aspects.

    Description: Fish and fishermen appear to be in a serious decline in New England. The haddock are overfished, inshore herring stocks are depleted, yellowtail flounder and lobster are scarce. The popular image is of grizzled fishermen, their boats chipped, scarred, old-fashioned hulks of wood tied up two and three abreast along the rotting wharves and piers of New England's depressed port towns. In this research project, we wanted to determine the state of the New England fishing industry and to propose acceptable methods for the management of the fishery. During our early discussions with the fishing industry people, we mentioned that we were interested in limited effort programs as they might be applied to New England fishermen. We carefully, and probably tediously, explained the "theory of limited effort" and we were generally thought to be daft. We were told we had things backwards--that the fishing industry needed more fish, more men, more boats - and that the way to accomplish this was to get a 200-mile fishing limit and kick the foreigners out. One of these wishes has come true - in the spring of 1976, P.L. 94-265 established a 200-mile fishing zone off the United States, with regional management councils to make management plans and allocate the resources first to United States fishermen, with surpluses to foreign fishermen.

    Description: Population dynamics and evolutionary change are linked by the fundamental biological processes of birth and death. This means that population growth may correlate with the strength of selection, whereas evolutionary change can leave an ecological signature. We decompose population growth in an age-structured population into contributions from variation in a quantitative trait. We report that the distribution of body sizes within a population of Soay sheep can markedly influence population dynamics, accounting for up to one-fifth of observed population growth. Our results suggest that there is substantial opportunity for evolutionary dynamics to leave an ecological signature and visa versa.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pelletier, Fanie -- Clutton-Brock, Tim -- Pemberton, Josephine -- Tuljapurkar, Shripad -- Coulson, Tim -- P01 AG 22500/AG/NIA NIH HHS/ -- P01 AG022500/AG/NIA NIH HHS/ -- P01 AG022500-04/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2007 Mar 16;315(5818):1571-4.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Division of Biology and the Natural Environment Research Council (NERC) Centre for Population Biology, Imperial College London, Silwood Park, Ascot, Berkshire, SL5 7PY, UK.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17363672" target="_blank"〉PubMed〈/a〉

    Description: Understanding the relationship between diversity and stability requires a knowledge of how species interact with each other and how each is affected by the environment. The relationship is also complex, because the concept of stability is multifaceted; different types of stability describing different properties of ecosystems lead to multiple diversity-stability relationships. A growing number of empirical studies demonstrate positive diversity-stability relationships. These studies, however, have emphasized only a few types of stability, and they rarely uncover the mechanisms responsible for stability. Because anthropogenic changes often affect stability and diversity simultaneously, diversity-stability relationships cannot be understood outside the context of the environmental drivers affecting both. This shifts attention away from diversity-stability relationships toward the multiple factors, including diversity, that dictate the stability of ecosystems.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ives, Anthony R -- Carpenter, Stephen R -- New York, N.Y. -- Science. 2007 Jul 6;317(5834):58-62.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Zoology, University of Wisconsin, Madison, WI 53706, USA. arives@wisc.edu.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17615333" target="_blank"〉PubMed〈/a〉
