The tropics surround the Equator limited in latitude by the Tropic of Cancer in the northern hemisphere and the Tropic of Capricorn in the southern hemisphere. The tropics include all the regions on Earth where the Sun reaches a point directly overhead at least once during the solar year. The subtropics are geographic and climate zones located between the tropic circle of latitude and the 38th parallel in each hemisphere. The tropics and subtropics are home to about 75% of the global human population. Cultural, economic, and political circumstances vary enormously across this vast geography of some 170 countries and territories. The regions not only harbor the world's poorest countries but their human populations are growing disproportionally faster than in temperate zones. Some countries are developing rapidly - Brazil, China, India, and Mexico being obvious examples, while others still remain in the poverty trap.This region contains an astonishing proportion of global biodiversity; some 90% of plant and animal species by some measures. Its contribution to human well-being is astounding. It was the birthplace for our species; and it hosts a myriad of plant and animal species which products feed us, keep us healthy, and supply us with a variety of material goods. The tropics and subtropics are also a natural laboratory where some of humanity's most important scientific discoveries have been made. Such biodiversity has enormous implications for research priorities, capacity building, and policy to address the challenges of conserving this region.Tropical Conservation: Perspectives on Local and Global Priorities drew the majority of its contributors from this growing pool of scientists and practitioners working in Latin America, Africa, and Asia. It introduces important conservation concepts and illustrates their application as the authors directly capture real world experiences in their home countries in preventing biodiversity loss and sustaining ecological health. Today, no part of the world can be viewed in isolation, and we further codify and integrate a range of approaches for addressing global threats to nature and environmental sustainability, including climate change and emerging diseases. Five sections structure the major themes.

This book provides complete, comprehensive, and broad subject-based reviews for students, teachers, researchers, policymakers, conservationists, and NGOs interested in the biodiversity and conservation of woody plants. Forests cover approximately 31 percent of the world’s total landmass; 93 percent is natural forest and only 7 percent consists of planted trees. Forest decline is progressing at an alarming rate worldwide. In addition to human activities (logging, deforestation, and exploiting forest lands for agriculture and industrial use), a number of other factors – including pests and diseases, drought, soil acidity, radiation, and ozone – are cumulatively contributing to global forest decline.  The present situation forces us to focus on forest conservation strategies for the present and future. Gene conservation and maintaining genetic diversity in forest ecosystems are crucial to the preservation of forest genetic resources. This calls for integrated action to implement both the in situ (on site) preservation of forest stands and ex situ (distant from the original site) strategies for the conservation of woody plants’ genetic resources. Selected priority areas include: 1) assessing patterns of genetic diversity and threats, 2) understanding the biological processes regulating genetic diversity, 3) assessing the impact of human activities and climate change on genetic diversity, and 5) finding methods for prioritizing species and populations for the conservation of forest trees genetic resources. All chapters were written by leading scientists in their respective fields, which include: woody plant diversity, ecology and evolution; assessment of genetic diversity in forest tree populations; conservation planning under climate change; and in situ and ex situ strategies, including biotechnological approaches, for the conservation of woody plants genetic resources.

This book presents extensive and new information on the Cenozoic marine and continental systems of one of the most important world heritage sites of Southern South America: The Península Valdés. From an interdisciplinary approach, that includes geological, biological and archeological perspectives of more than 30 specialists, an integrated description and analysis of the Cenozoic environments of the study region is carried on. The volume brings together an update of the geology, climate, geomorphology, soils, biodiversity, archeology and human impact of the Península Valdés. The scope of this book extends to any natural science researcher of the world interested on the Cenozoic history of the Península Valdés.

Hubert REEVES est astrophysicien. Ancien conseiller scientifique à la NASA Institute for Space Studies, Prix de la Société française de Physique, Prix Albert Einstein, il est nommé en 2016 par le Ministère de l’Environnement Président d’honneur de l’Agence française pour la Biodiversité. Cette même année, après le succès de son livre L’Univers expliqué à mes petits-enfants, il commence sa collaboration avec le dessinateur Daniel casanave en publiant L’Univers dans la collection de La Petite Bédétèque des Savoirs aux Éditions du Lombard.

This entirely updated second edition provides an overview on the biology, ecology and biodiversity of extremophiles. Unusual and less explored ecosystems inhabited by extremophiles such as marine hypersaline deeps, extreme cold, desert sands, and man-made clean rooms for spacecraft assembly are presented. An additional focus is put on the role of these highly specialized microorganism in applied research fields, ranging from biotechnology and nanotechnology to astrobiology. Examples such as novel psychrophilic enzymes, compounds from halophiles, and detection strategies for potential extraterrestrial life forms are discussed in detail. The book addresses researchers and advanced students in the fields of microbiology, microbial ecology and biotechnology.
