Book Description
Life began in the sea, and even today most of the deep diversity of the planet is marine. This is often forgotten, especially in tropical countries like Costa Rica, renowned for their rain forests and the multitude of life forms found therein. Thus this book focusing on marine diversity of Costa Rica is particularly welcome. How many marine species are there in Costa Rica? The authors report a total of 6,777 species, or 3. 5% of the world’s total. Yet the vast majority of marine species have yet to be formally described. Recent estimates of the numbers of species on coral reefs range from 1–9 million, so that the true number of marine species in Costa Rica is certainly far higher. In some groups the numbers are likely to be vastly higher because to date they have been so little studied. Only one species of nematode is reported, despite the fact that it has been said that nematodes are the most diverse of all marine groups. In better studied groups such as mollusks and crustaceans, reported numbers are in the thousands, but even in these groups many species remain to be described. Indeed the task of describing marine species is daunting – if there really are about 9 million marine species and Costa Rica has 3. 5% of them, then the total number would be over 300,000. Clearly, so much remains to be done that new approaches are needed. Genetic methods have en- mous promise in this regard.

Book Description
Natural History and Ecology of Mexico and Central America presents an interesting overview of the frontiers of biodiversity and ecological research in the geographical area of Mexico and Central America. Chapters cover such topics as biodiversity and ecology of plant communities, tropical subterranean ecosystems, floating Sargassum species, the endangered species Dioon edule, Kemp’s ridley sea turtles, fish and fisheries, urbanization and bats, and food and sustainable diet.

Book Description
Latin America and the Caribbean (LAC) region is exceptionally biodiverse. It contains about half of the world’s remaining tropical forests, nearly one-fifth of its coastal habitats, and some of its most productive agricultural and marine areas. But agriculture, fishing and other human activities linked to rapid population and economic growth increasingly threaten that biodiversity. Moreover, poverty, weak regulatory capacity, and limited political will hamper conservation. Given this dilemma, it is critically important to design conservation strategies on the basis of the best available information about both biodiversity and the track records of the various policies that have been used to protect it. This rigorously researched book has three key aims. It describes the status of biodiversity in LAC, the main threats to this biodiversity, and the drivers of these threats. It identifies the main policies being used to conserve biodiversity and assesses their effectiveness and potential for further implementation. It proposes five specific lines of practical action for conserving LAC biodiversity, based on: green agriculture; strengthening terrestrial protected areas and co-management; improving environmental governance; strengthening coastal and marine resource management; and improving biodiversity data and policy evaluation.

Book Description
This report synthesises key findings on biodiversity and ecosystem services from the Environmental Performance Reviews completed for Brazil, Chile, Colombia, Mexico and Peru between 2013 and 2017. The report aims to provide a sense of the common challenges facing these Latin American countries, the strategies being used to tackle them, the gaps that remain and how these can be addressed. Focusing on Latin America is particularly pertinent given the great wealth of biodiversity in the region and the growing pressures on its conservation and sustainable use.

Book Description
This book highlights key results and lessons learnt from two field sites, La Suerte in Costa Rica and Ometepe Nicaragua. It provides long term data on species abundance and distribution. Primates receive specific attention in this book, as they are flagship species and good indicators for the “health” of an ecosystem, but as well a money maker. Many primate species are sensitive to habitat alteration, and are often hunted out first. But they play an important role as seed dispersal agents for the regeneration of the forest. The book then compares results from the two field sites with regional trends, and explores potential solutions such as REDD+. This book strongly calls for new approaches in conservation, it makes the case for looking beyond the pure species biology and classic conservation angle and to take into account the economic and political realities.

Book Description
This is the only comprehensive guide to mammals in Central America and Southeast Mexico. Unlike most field guides, it covers smaller mammals in depth and also provides an extensive bibliography. In addition to detailed species accounts and range maps for all species, the book has 52 full-color plates. The 49 animal plates cover almost all the species in the region. 4 color maps are new to the second edition, detailing parks, elevations and biomes in the region.

Book Description
Abstract: "A "forest-hydrology-poverty nexus" hypothesis asserts that deforestation in poor upland areas simultaneously threatens biodiversity and increases the incidence of flooding, sedimentation, and other damaging hydrological processes. Nelson and Chomitz use rough heuristics to assess the applicability of this hypothesis to Central America. They do so by using a simple rule of thumb to identify watersheds at greater risk of hydrologically significant land use change: these are watersheds where there is a relatively large interface between agriculture and forest, and where this interface is on a steep slope. The authors compare the location of these watersheds with spatial maps of poverty and forests (for Guatemala and Honduras) and with maps of population and forests (for Central America at large). The analysis is performed for watersheds defined at different scales. The authors find plausible evidence for a forest-biodiversity-poverty connection in Guatemala, and to a lesser extent in Honduras. In the rest of Central America, there are relatively few areas where forest meets agriculture on steep slopes--either the forest or the slopes are lacking. And the ratio of these forest/agriculture/hillside interfaces to watershed area declines markedly as larger-scale watersheds are considered. This directs attention to relatively small watersheds for further investigation of the "nexus." This paper--a product of the Infrastructure and Environment Team, Development Research Group--is part of a larger effort in the group to understand the economics of conservation"--World Bank web site.
