Endemism in Vascular Plants


Book Description

The book is the first comprehensive analysis of the macroecology and geobotany of endemic vascular plants with case-studies and analyses from different regions in the world. Endemism is a pre-extinction phenomenon. Endemics are threatened with extinction. Due to international nature conservation policies and due to the perception of the public the concept’s importance is increasing. Endemism can result from different biological and environmental processes. Depending on the process conservation measures should be adapted. Endemic vascular plant taxa, in the setting of their species composition and vegetation types are important features of landscapes and indicators of the quality of relating habitats. The book is an important basis for biologists, ecologists, geographers, planners and managers of nature reserves and national parks, and people generally interested in nature conservation and biogeography of vascular plants.




Analytical Biogeography


Book Description

Biogeography may be defined simply as the study of the geographical distribution of organisms, but this simple definition hides the great complexity of the subject. Biogeography transcends classical subject areas and involves a range of scientific disciplines that includes geogra phy, geology and biology. Not surprisingly, therefore, it means rather different things to different people. Historically, the study of biogeogra phy has been concentrated into compartments at separate points along a spatio-temporal gradient. At one end of the gradient, ecological biogeography is concerned with ecological processes occurring over short temporal and small spatial scales, whilst at the other end, historical biogeography is concerned with evolutionary processes over millions of years on a large, often global scale. Between these end points lies a third major compartment concerned with the profound effects of Pleistocene glaciations and how these have affected the distribution of recent organisms. Within each of these compartments along the scale gradient, a large number of theories, hypotheses and models have been proposed in an attempt to explain the present and past biotic distribution patterns. To a large extent, these compartments of the subject have been non-interactive, which is understandable from the different interests and backgrounds of the various researchers. Nevertheless, the distribu tions of organisms across the globe cannot be fully understood without a knowledge of the full spectrum of ecological and historical processes. There are no degrees in biogeography and today's biogeographers are primarily born out of some other discipline.







Hotspots


Book Description

Includes sections on Polynesia and Micronesia, the California coast, the Caribbean, Choco-Darien Western Ecuador, the Mediterranean Basin, Brazilian Cerrado, Tropical Andes, Central Chile, Atlantic Forest Region, the Caucasus, the Mountains of South-Central China, India and Burma, Eastern Arc Mountains and Coastal Forests of Tanzania and Kenya, Guinean Forest of West Africa, Succulent Karoo, Cape Floristic Province, Madagascar and Indian Ocean Islands, Western Ghats and Sri Lanka, Sundaland, Wallecea, Southwest Australia, the Philippines, New Caledonia, and New Zealand.




Endemic Species


Book Description

This book consists of several thematic groups, including botany, zoology and topics related to human health. In regards to botany, chapters discuss endemic plants of Bolivia, Mexico, Italy and the Caribbean. They show the diversity, distribution and conservation of many species. In regards to zoology, the book highlights endemic primates and reptiles. Additionally, the book presents other environmental issues relevant to conservation. This volume also presents topics related to health, some of which are relevant for their implications on health and the economy, is the case of the presence of toxins in the Pacific plankton.All chapters present relevant content for future research or because they are fundamental for territorial management.







Perspectives on Spatial Data Analysis


Book Description

Spatial data analysis has seen explosive growth in recent years. Both in mainstream statistics and econometrics as well as in many applied ?elds, the attention to space, location, and interaction has become an important feature of scholarly work. The methodsdevelopedto dealwith problemsofspatialpatternrecognition,spatialau- correlation, and spatial heterogeneity have seen greatly increased adoption, in part due to the availability of user friendlydesktopsoftware. Throughhis theoretical and appliedwork,ArthurGetishasbeena majorcontributing?gureinthisdevelopment. In this volume, we take both a retrospective and a prospective view of the ?eld. We use the occasion of the retirement and move to emeritus status of Arthur Getis to highlight the contributions of his work. In addition, we aim to place it into perspective in light of the current state of the art and future directions in spatial data analysis. To this end, we elected to combine reprints of selected classic contributions by Getiswithchapterswrittenbykeyspatialscientists.Thesescholarswerespeci?cally invited to react to the earlier work by Getis with an eye toward assessing its impact, tracing out the evolution of related research, and to re?ect on the future broadening of spatial analysis. The organizationof the book follows four main themes in Getis’ contributions: • Spatial analysis • Pattern analysis • Local statistics • Applications For each of these themes, the chapters provide a historical perspective on early methodological developments and theoretical insights, assessments of these c- tributions in light of the current state of the art, as well as descriptions of new techniques and applications.




Balkan Biodiversity


Book Description

This is the first attempt to synthesize current understanding of biodiversity in the great European hot spot. A diverse group of international researchers offers perspective on biodiversity at the level of the gene, species and ecosystem, including contributions on temporal change. Biological groups include plants, mammals, spiders and humans, cave-dwelling organisms, fish, aquatic invertebrates and algae.




Mountain Biodiversity


Book Description

This book is the result of the first global conference on mountain biodiversity, and is a contribution to the International Year of Mountains, 2002. The Global Mountain Biodiversity Assessment program is a Special Target Area Region project of DIVERSITAS (UNESCO and UNEP). Biological diversity is essential for the integrity of mountain ecosystems and this dependency is likely to increase as environmental (climate) and social conditions change. Steep terrain and climate, and severe land-use pressure cause mountain ecosystems to rank among the world's most endangered landscapes. The 28 chapters in this book represent research on the biological riches in all major mountain ranges of the world, and synthesize existing knowledge on mountain biodiversity - from diversity of bacteria, plants and animals to human diversity. The book is divided into five sections: an introduction providing an overview of the issues; plant and animal diversity; climate change and mountain biodiversity; land use and conservation; and a synthesis.
