    Keywords: climate change
    Description / Table of Contents: This book provides an interdisciplinary view of how to prepare the ecological and socio-economic systems to the reality of climate change. Scientifically sound tools are needed to predict its effects on regional, rather than global, scales, as it is the level at which socio-economic plans are designed and natural ecosystem reacts. The first section of this book describes a series of methods and models to downscale the global predictions of climate change, estimate its effects on biophysical systems and monitor the changes as they occur. To reduce the magnitude of these changes, new ways of economic activity must be implemented. The second section of this book explores different options to reduce greenhouse emissions from activities such as forestry, industry and urban development. However, it is becoming increasingly clear that climate change can be minimized, but not avoided, and therefore the socio-economic systems around the world will have to adapt to the new conditions to reduce the adverse impacts to the minimum. The last section of this book explores some options for adaptation.

    Keywords: climate change
    Description / Table of Contents: This book offers an interdisciplinary view of the biophysical issues related to climate change. Climate change is a phenomenon by which the long-term averages of weather events (i.e. temperature, precipitation, wind speed, etc.) that define the climate of a region are not constant but change over time. There have been a series of past periods of climatic change, registered in historical or paleoecological records. In the first section of this book, a series of state-of-the-art research projects explore the biophysical causes for climate change and the techniques currently being used and developed for its detection in several regions of the world. The second section of the book explores the effects that have been reported already on the flora and fauna in different ecosystems around the globe. Among them, the ecosystems and landscapes in arctic and alpine regions are expected to be among the most affected by the change in climate, as they will suffer the more intense changes. The final section of this book explores in detail those issues.

    Description / Table of Contents: The term biodiversity has become a mainstream concept that can be found in any newspaper at any given time. Concerns on biodiversity protection are usually linked to species protection and extinction risks for iconic species, such as whales, pandas and so on. However, conserving biodiversity has much deeper implications than preserving a few (although important) species. Biodiversity in ecosystems is tightly linked to ecosystem functions such as biomass production, organic matter decomposition, ecosystem resilience, and others. Many of these ecological processes are also directly implied in services that the humankind obtains from ecosystems. The first part of this book will introduce different concepts and theories important to understand the links between ecosystem function and ecosystem biodiversity. The second part of the book provides a wide range of different studies showcasing the evidence and practical implications of such relationships.

    Description: Geography and associated hydrological, hydroclimate and land use conditions and their changes determine the states and dynamics of wetlands and their ecosystem services. The influences of these controls are not limited to just the local scale of each individual wetland, but extend over larger landscape areas that integrate multiple wetlands and their total hydrological catchment – the wetlandscape. However, the data and knowledge of conditions and changes over entire wetlandscapes are still scarce, limiting the capacity to accurately understand and manage critical wetland ecosystems and their services under global change. We present a new Wetlandscape Change Information Database (WetCID), consisting of geographic, hydrological, hydroclimate and land use information and data for 27 wetlandscapes around the world. This combines survey-based local information with geographic shapefiles and gridded datasets of large-scale hydroclimate and land-use conditions and their changes over whole wetlandscapes. Temporally, WetCID contains 30-year time series of data for mean monthly precipitation and temperature, and annual land use conditions. The survey-based site information includes local knowledge on the wetlands, hydrology, hydroclimate and land uses within each wetlandscape, and on the availability and accessibility of associated local data. This novel database can support site assessments, cross-regional comparisons, and scenario analyses of the roles and impacts of land use, hydroclimatic and wetland conditions and changes on whole-wetlandscape functions and ecosystem services.

    Notes: Abstract In Chlamydomonas reinhardtii there are three glutamate dehydrogenase isozymes which can use both NADH and NADPH as cofactors and respond differently to different nitrogen sources and several stress conditions. From data of induction of isozymes in different metabolic situations, we propose a possible physiological role for each of them in algal carbon and nitrogen metabolism.

    Notes: The isolation and characterization of an l-aspartate aminotransferase (AAT) activity (EC 2.6.1.1) in the unicellular green alga Chlamydomonas reinhardtii 6145c are reported for the first time. The enzyme transaminates aspartate with the 2-oxoglutarate-glutamate system, and exhibits maximum aminotransferase activity at pH 7.8 and 37°C. It has an Mr of 138 kDa, contains pyridoxal 5′-phosphate, and has a Km apparent for oxalacetate of 0.55 mM and exhibits positive co-operativity with l-aspartate with an S0.5 of 2.53 mM and a Hill coefficient of 1.57. In vivo, activity levels were affected by the carbon and nitrogen sources and by the change in the dark-light conditions. All these responses are interpreted in terms of a possible physiological regulation of AAT activity to keep the intracellular pools of glutamate and aspartate within margins compatible with environmental fluctuations.

    Description / Table of Contents: Résumé On a étudié les résultats comparatifs des réactions intradermiques à la tuberculine, histoplasmine et coccidioidine, pratiquées simultanément sur 644 malades tuberculeux hospitalisés dans les Sanatoriums „Simón Bolívar“, „Andrés Herrera Vegas“, „Luisa Cáceres de Arismendi“ et Padre Cabrera, population représentative de l'isolement hospitalier pour cette maladie dans le District Fédéral et l'Etat Miranda, sans faire de distinction de la classe de tuberculose présente dans les sujets, ni référence aux traitements en vigueur au moment des preuves. L'ensemble a été formé de: 132 enfants et 512 adultes, avec un nombre sensiblement égal d'hommes et de femmes, entre les âges de moins d'l an à 60 ans et plus avec une prédominance de l'âge juvénile de 15 à 40 ans. On classe comme réacteur toute induration intradermique palpable de 5 mm et plus. Dans la tuberculine on prouve qu'à la dose unique de 5 U. (0.0001 milligrammes T.P.P.D.), peu de cas échappent au signe de positivité, surtout chez les enfants jusqu'à 14 ans (99,2 %) et adultes jeunes. La fréquence générale de preuve pour tout âge fut de 96,2 %. A l'histoplasmine on vérifie une fréquence de réacteurs de 28 % pour tout âge; 30,5 % chez les hommes et 25,2 % chez les femmes. La positivité croit progressivement après 10 ans, avec prédominance de l'infection chez l'homme. Avec la Coccidioidine on a obtenu 2 % de réacteurs, 13 cas en total: 11 adultes et 2 enfants, positivité qui fut 9 fois chez les hommes et 4 fois chez les femmes. En ce qui concerne l'intensité des réactions, la fréquence des mesures démontra, qu'avec la tuberculine il y a prédominance des réactions de plus grandes dimensions, comme l'on pouvait s'y attendre dans des réacteurs stimulés par la maladie évolutive; ces mesures sont plus grandes que celles observées avec l'histoplasmine, dont les milieux d'induration sont supérieurs à ceux obtenus avec la Coccidioidine. Les réactions dimensionnelles de plus basse induration (5 à 8 millimètres) sont communes dans les résultats des trois épreuves, bien qu'avec des fréquences différentes: 5,4 % pour la tuberculine, 2,6 % pour l'histoplasmine et 0,31 % pour la coccidioidine, admettant comme certain que les réponses à la première preuve furent influencées par les sensibilisants de la maladie, la spécificité ne donnant lieu à aucun doute; le fait suggère que les réactions avec mesures de basse dimension n'ont aucune relation avec la spécificité des réponses. Nous détachons le fait en impliquant que, dans la pratique, on peut qualifier comme non spécifiques les réactions homologues de basse dimension obtenues avec d'autres antigènes sur des personnes saines. Dans la distribution comparée des mesures des réactions à la tuberculine, on a pu démontrer la plus grande intensité des réactions sur des enfants parce qu'il s'agit de l'expression allergique à la première infection. Pour les autres âges, de 15 à 60 ans, l'intensité des réactions s'accroit jusqu'à 39 ans et décroit sur les sujets de 40 à 60 ans, démontrant ainsi que l'allergie dans les tuberculoses suit un cours parallèle à celui observé avec l'allergie dans la maladie latente. Egalement, on démontre une plus grande dimension des mesures chez les femmes que chez les hommes, tant chez les enfants que chez les adultes, concept fréquemment tenu comme exclusif à cet âge. Avec l'histoplasmine on a démontré une intensité des réactions qui croît parallèlement à l'âge, jusqu'à 60 ans, ce qui a été interprêté comme une sensibilité stimulée dans le temps par des infections répétées et avec la preuve de ce que l'état de maladie tuberculeuse et son allergie n'influencent pas l'intensité des réactions à l'histoplasmine, maintenant que nous avons démontré un phénomène contraire avec la tuberculine. Avec la coccidioidine même avec le petit nombre de réacteurs à cette épreuve, on a pu apprécier une augmentation de l'intensité des réactions avec l'âge. On n'a pas observé d'influence du sexe dans les mesures observées avec l'histoplasmine, en plus avec la coccidioidine le milieu d'induration plus grand fut obtenu chez les hommes. La corrélation des résultats positifs dans les trois épreuves, fut inespérée, une association exagérée entre les réacteurs à la coccidioidine avec les cas de positivité à l'histoplasmine (C+H+). Le fait fut intéressant en ce sens qu'il nous a indiqué dans un autre travail la vérification de réactions positives non spécifiques à la coccidioidine sur des souris infectées avec l'Histoplasma capsulatum. Même avec cette similitude de faits, nous jugeons que la méthodologie pour mettre en évidence la non spécificité des réponses allergiques à ces champignons est très exigente et en dehors de la portée de la méthode epidémiologique.
    Abstract: Summary The comparative results of intradermal tests are presented which were carried out with tuberculin, histoplasmin, and coccidioidin simultaneously on 644 tuberculous patients. They were hospitalized in the Sanatoria „Simón Bolívar, „Andrés Herrera Vegas“, „Luisa Cáceres de Arismendi, and „Padre Cabrera“. These patients were representative for the hospital population in the Federal District (Caracas) and in the State of Miranda. There was no distinction made what type of tuberculosis the patients had, nor what kind of treatment they received at the moment. The total encompassed 132 children and 512 adults, divided almost equally between male and female, in the age of 1 to 60 years, with a preponderance of the age between 15 and 40. The skin test was considered positive with an induration measuring 5 mm or more. The tuberculin test was positive with five units (0.0001 mg, T.P.P.D.) especially in the children up to 14 year of age (99.2 %) and in young adults. This test was positive for all ages in 96.2 %. The histoplasmin test was positive for all ages in 28 %; 30.5 % for the male and 25.2 % for the female. The positive reactions are increasing after 10 years of age, with the predominance of the infection in adult man. The coccidioidin test was positive in 2 %, in the total of 13 cases: 11 adults and 2 children, 9 times in the male and 4 times in the female. As to the intensity of the reaction in decreasing order: most intensive was the tuberculin test, followed by histoplasmin and the least with coccidioidin. The reactions with the smallest induration (5 to 8 mm occurred) 5.4 % for tuberculin, 2.6 % for histoplasmin and 0.31 % for coccidioidin. It is assumed with certainty that the first tests were influenced by sensitization factors of the disease, however, the specificity was beyond doubt. In the practice, however, one can consider as non-specific the homologous reactions with small induration which were obtained in healthy persons with other antigens. In the comparative distribution of the numerical size of the reactions the tuberculin test showed the greatest intensity in children as an expression of the allergic reaction to the first infection. For the ages of from 15 to 60 years, the intensity of the reaction is increasing up to the age of 39 years and decreasing in the years from 40 to 60, revealing that the allergy in tuberculosis follows a course parallel with the allergy in the latent disease. The reactions were more intensive in the female than in the male, both in children and in adults. With histoplasmin the intensity of the reaction increased parellel with the age, up to 60 years. This is interpreted as a sensibility stimulated in time by repeated infections and as an evidence that tuberculosis and its allergy does not influence the intensity of the reaction to histoplasmin. With coccidioidin the increase of the intensity of the reaction with age was observed even in these small number of cases. One did not observe the influence of sex in the size of the reaction with histoplasmin, while the largest reaction with coccidioidin was seen in the male. The correlation of the positive tests with the three antigens was unexpected: a high degree of cross reaction between coccidioidin and histoplasmin. This fact was interesting because in an experiment the mice infected withH. capsulatum showed a positive non-specific reaction to coccidioidin. Even with this similarity of facts, the methodology is too difficult to prove the non-specificity of the allergic reactions to these three fungi and it is certainly beyond the reach of the epidemiologic research.
    Notes: Resumen Se estudiaron los resultados comparativos de las reacciones intradérmicas a la Tuberculina, Histoplasmina y Coccidioidina, practicadas simultáneamente a 644 enfermos tuberculosos hospitalizados en los Sanatorios „Simón Bolívar“, „Andrés Herrera Vegas“, „Luisa Cáceres de Arismendi“ y „Padre Cabrera“, población representativa del aislamiento hospitalario para esta enfermedad en el Distrito Federal y Estado Miranda, sin hacer distinción de la clase de tuberculosis presente en los sujetos, ni referencia a los tratamientos vigentes en el momento de las pruebas. El conjunto lo formó: 132 niños y 512 adultos, con un número sensiblemente igual de varones y hembras, entre las edades de menos de 1 a 60 años y más con un predominio de la edad juvenil de 15 a 40 años. Se clasificó como reactor toda induración intradérmica palpable de 5 mms. y más. En la Tuberculina se comprobó que a la dosis única de 5 U. (0.0001 miligramos de T.P.P.D.), muy pocos casos escapan al signo de positividad, sobre todo en niños hasta los 14 años, (99,2 %) y adultos jóvenes. La frecuencia general de la prueba para toda edad fué de 96,2 %. A la Histoplasmina se comprobó una frecuencia de reactores de 28 % para toda edad; 30,5 % en varones y 25,2 % en hembras. La positividad crece progresivamente después de los 10 años, con predominio de la infección en el hombre. Con la Coccidioidina se obtuvo un 2 % de reactores, 13 casos en total; 11 adultos y 2 niños, positividad que fué 9 veces en varones y 4 en hembras. En lo que respecta a la intensidad de las reacciones, la frecuencia de las medidas demostró: que con la tuberculina hay predominio de reacciones de mayores dimensiones, lo que era de esperarse en reactores estimulados por la enfermedad evolutiva; mayores estas medidas de lo observado con la histoplasmina, cuyos promedios de induración superan al obtenido con la Coccidioidina. Son comunes en los resultados a las tres pruebas las reacciones dimensionales de más baja induración (5 a 8 milímetros) aunque con frecuencias diferentes: 5,4 % para la tuberculina, 2,6 % para la Histoplasmina y 0,31 % para la Coccidioidina, aceptando como cierto que las respuestas a la primera prueba estuvieron influenciadas por los sensibilizantes de la enfermedad, por lo que su especificidad no dió lugar a dudas; el hecho sugiere que las reacciones con medidas de baja dimensión, no tienen relación con la especificidad de las respuestas. Destacamos el hecho por las implicaciones que en la práctica pueda tener el calificar como inespecíficas reacciones homólogas de baja dimensión obtenidas con otros antígenos en personas no enfermas. En la distribución comparada de medidas de las reacciones a la tuberculina, pudo demostrarse la mayor intensidad de las reacciones en niños por tratarse en éstos, de la expresión alérgica a la primera infección. En las otras edades 15 a 60 años la intensidad de las reacciones se incrementa hasta los 39 años y decrece en los sujetos de 40 a 60 años, demostrándose con ello que la alergia en los tuberculosos sigue en curso paralelo a lo observado con la alergia en la enfermedad latente. También se demostró mayor dimensión de las medidas en las hembras que en los varones, tanto en niños como adultos, concepto tenido frecuentemente como exclusivo de esta edad. Con la Histoplasmina se demostró una intensidad de las reacciones que se incrementa paralelo a la edad hasta los sesenta años, lo que se interpretó como una sensibilidad estimulada en el tiempo por repetidas infecciones y como una prueba de que el estado de enfermedad tuberculosa y su alergia no influencia la intensidad de las reacciones a la histoplasmina ya que hemos demonstrado un fenómeno contrario con la tuberculina. Con la Coccidioidina aún con el escaso número de reactores a esta prueba, se pudo apreciar un incremento de la intensidad de las reacciones con la edad. No hubo influencia del sexo en las medidas observadas con la Histoplasmina, más, con la Coccidioidina el promedio de induración mayor se obtuvo en varones. La correlación de resultados positivos en las tres pruebas, resultó inesperada, una exagerada asociación entre los reactores a la Coccidioidina con los casos de positividad a la Histoplasmina (C+ H+). El hecho cobra interés por haber informado nosotros en otro trabajo la comprobación de reacciones positivas inespecíficas a la Coccidioidina en ratones infectados conHistoplasma capsulatum. Aún con esta similitud de hechos, juzgamos que la metodología para evidenciar la inespecificidad de las respuestas alérgicas a estos hongos es muy exigente y fuera del alcance del método epidemiologico.
