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
From two scientists who have been at the forefront of manatee research for over three decades, The Florida Manatee offers an engaging, accessible introduction to manatee biology, including communication, diet, long-distance migration, and much more. This second edition is updated with new scientific research, as well as discussions of recent conservation efforts—largely driven by manatee injuries and deaths resulting from boat collisions—that have contributed to the robust growth of manatee numbers in Florida. It also includes the latest predictions for manatee populations and health in the future, both in Florida and worldwide. This is the perfect book for anyone seeking the most comprehensive, current information on this fascinating marine mammal.

Book Description
This important scientific volume comprehensively explores the biology and ecological status of manatees and dugongs in all of the geographic regions where they can be found today, from the Caribbean to Eastern Africa, from Arabia to the Amazon, and from Japan through the South Pacific to Australia. Many of these dwindling populations are situated in developing countries--locales that have previously received little attention in the scientific literature. In these areas, people occupying rivers or coastlines still capture sirenians for food and other uses (oil, bones for carving, leather). In addition, disruption, erosion, or complete loss of sirenian habitat occurs because of dredge and fill, coastal run-off, chemical pollution, and damage from boat propellers. Sirenian Conservation features contributions from an international group of scientists who are working to address the many challenges to manatee and dugong food supply, environment, reproduction, and survival. They share stories of programs that rescue, rehabilitate, release, and monitor these animals; offer reports on practical, replicable, and cost-effective management techniques; and summarize current research strategies.

Book Description
This volume brings together perspectives from scholars of different scientific backgrounds endeavouring to understand and debate the interactions and relationships between humans, nonhuman species and natural ecosystems in order to overcome the classic human/environment dichotomy. Through discussions informed by the humanities, arts, social and natural sciences, the book deals with the way different disciplines approach this relationship. These diverse perspectives are compared to enable a cross-cutting analysis of human/nature interface throughout history. Changes forced by the utilization of resources and habitats, as well as climate changes are analysed and discussed, enhancing the importance of a multifaceted approach for a better understanding of the complexity of both the human/world relationship and diverse interspecies connections and impacts.
