Book Description
Madagascar is one of the most biologically diverse places on the planet, the result of 160 million years of isolation from the African mainland. More than 80% of its species are not found anywhere else on Earth. However, this highly diverse flora and fauna is threatened by habitat loss and fragmentation, and the island has been classified as one of the world’s highest conservation priorities. Drawing on insights from geography, anthropology, sustainable development, political science and ecology, this book provides a comprehensive assessment of the status of conservation and environmental management in Madagascar. It describes how conservation organisations have been experimenting with new forms of protected areas, community-based resource management, ecotourism, and payments for ecosystem services. But the country must also deal with pressing human needs. The problems of poverty, development, environmental justice, natural resource use and biodiversity conservation are shown to be interlinked in complex ways. Authors address key questions, such as who are the winners and losers in attempts to conserve biodiversity? And what are the implications of new forms of conservation for rural livelihoods and environmental justice?

Book Description
One needs to look at only a small portion of the enormous literature on plate tectonics published in the last 15 years to realize that there are many differences between the various reconstructions that have been presented. It becomes obvious that, although there is a general agreement about the presence of an assembly of continents (a Pangaea) in the early Mesozoic, there is considerable disagreement among earth scientists as to the configurement of the assembly and the manner and timing of the subsequent dispersal. While the revolution in geophysics was taking place, systematic work in paleontology and neontology was being carried out. This book is an attempt to incorporate the biological evidence into the theory of plate tectonics.The author traces the changing relationships among the various biogeographic regions and demonstrates how such changes may often be correlated with the gradual geographic alteration of the earth's surface. He analyses recent information about the distribution of widespread groups of terrestrial and freshwater vertebrates, invertebrates and plants, and discusses the biogeographical effects of the movement of oceanic plates.It is particularly important to obtain dependable information about certain critical times in the history of continental relationships. We need to know when the terrestrial parts of the earth were broken apart and when they were joined together. The present investigation makes it clear that we cannot depend entirely on evidence from plate tectonics nor will purely biological evidence suffice. This book thus provides much of interest to systematists working on contemporary groups of plants and animals, paleontologists, evolutionary biologists, and professors teaching courses in biogeography.

Book Description
"Near time" -an interval that spans the last 100,000 years or so of earth history-qualifies as a remarkable period for many reasons. From an anthropocentric point of view, the out standing feature of near time is the fact that the evolution, cultural diversification, and glob al spread of Homo sapiens have all occurred within it. From a wider biological perspective, however, the hallmark of near time is better conceived of as being one of enduring, repeat ed loss. The point is important. Despite the sense of uniqueness implicit in phrases like "the biodiversity crisis," meant to convey the notion that the present bout of extinctions is by far the worst endured in recent times, substantial losses have occurred throughout near time. In the majority of cases, these losses occurred when, and only when, people began to ex pand across areas that had never before experienced their presence. Although the explana tion for these correlations in time and space may seem obvious, it is one thing to rhetori cally observe that there is a connection between humans and recent extinctions, and quite another to demonstrate it scientifically. How should this be done? Traditionally, the study of past extinctions has fallen largely to researchers steeped in such disciplines as paleontology, systematics, and paleoecology. The evaluation of future losses, by contrast, has lain almost exclusively within the domain of conservation biolo gists. Now, more than ever, there is opportunity for overlap and sharing of information.

Book Description
This volume includes up-to-date field research on the longest-studied and best known of lemur species. It contains articles by scientists from America, Europe, Japan and Madagascar, who combine their knowledge to describe an animal which is unique among primates. The papers review past research and add new dimensions of research related to nutrition, health, hormonal biology, plant ecology, behavioral ecology, and demography of Lemur catta.

Book Description
Primate Biogeography is a subject rarely addressed as a discipline in its own right. This comprehensive source introduces the reader to Primate Biogeography as a discipline. It highlights the many factors that may influence the distribution of primates, and reveals the wide range of approaches that are available to understanding the distribution of this order. The biogeography of primates in the past is a major component of our understanding of their evolutionary history and is an essential component of conservation biology. This book will appeal to primatologists, physical anthropologists, zoologists, and undergraduates in these areas.

Book Description
Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.

Book Description
Molecular studies reveal highly ordered geographic patterns in plant and animal distributions. The tropics illustrate these patterns of community immobilism leading to allopatric differentiation, as well as other patterns of mobilism, range expansion, and overlap of taxa. Integrating Earth history and biogeography, Molecular Panbiogeography of the Tropics is an alternative view of distributional history in which groups are older than suggested by fossils and fossil-calibrated molecular clocks. The author discusses possible causes for the endemism of high-level taxa in tropical America and Madagascar, and overlapping clades in South America, Africa, and Asia. The book concludes with a critique of adaptation by selection, founded on biogeography and recent work in genetics.
