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.

Reviews the current status of plant conservation in the southwestern U.S., citing specific cases from surveys, and genetic, demographic, and ecological studies. In addition, broad issues affecting the paradigms of conservation of rare plants species in an ecosystem management context are reviewed. Contents: public involvement in plant conservation; demography; genetics; issues concerning rarity and preserving biodiversity; reproductive and pollination biology; autecology; strategies for protection in an ecosystem context; and surveys and monitoring. 40 papers. Illus.

Comprehensive illustrated guide to plant science and ecology of southern African vegetation.

Blending scientific and legal expertise, Kunich proves that a devastating ecological crisis is imminent or even underway already, and that conservation law has yet to catch up with biological science. He challenges readers with a hotspots wager, arguing that he have vastly more to gain than lose by legally protecting biological hotspots, and that foregoing them in favor of the relatively minor and immediate returns arising from their devastation is both foolish and, ultimately, dangerous. Legal thought lags behind modern science in focusing on and setting priorities for global conservation. An extinction spasm is imminent, many scientists argue, due to the ongoing global devastation of biological hotspots, home to a disproportionate share of all life forms, including perhaps millions of unknown species. These hotspots have already lost 88 percent of their primary vegetation and are likely to lose much more, yet few legal measures exist to protect them. Environmental legal protections are often incomprehensive and feebly enforced. Even worse, 62 percent of all hotspots are unprotected. Kunich provides a brief history and science of extinction. He discusses the importance of saving species from extinction and analyzes the legal measures directed toward preserving biodiversity in nations that harbor hotspots.

This is a comprehensive regional geography synthesis of the most important physical and human spatial processes that shaped Serbia and led to many interesting regional issues, not only to Serbia but to the Balkans and Europe. The book provides an overall view on the Serbian physical environment, its population and economy. It also highlights important regional issues such as regional disparities and depopulation, sustainable development and ecological issues and rural economy in the context of rural area development, which have been shaped by different political and historical processes. This highly illustrated book provides interesting and informative insights into Serbia and its context within the Balkans and Europe. It appeals to scientists and students as well as travelers and general readers interested in this region.

The novelty of the book is a strong focus on perception, perspectives and prediction by scientists with profound insight into the ecology of ecosystems or into human demands and activity. The challenge is to bridge from empirical data and the knowledge of the past to the possibilities of the performance in the future. We assume that there is scope for more cooperation between the fields of ecology and practical philosophy or other social sciences in organising ecosystems and shaping the cultural future of humankind, and that such collaboration should be accorded considerably more priority. This book deals with environmental processes seen within a framework of the nature of ecosystems and human cultures. The future of the environment, the development of ecosystems and effective nature conservation management are the essentials of this book. Human nature and culture, and in particular their interactions, are interpreted as a set of rules and as given. The aim is not only to assess the significance of human influence on species composition and biodiversity but also to weigh up the subsequent potentials for action. In this book we will analyze the problems independently of one another, even if they are interconnected. This book focuses on perspectives and prognoses for the impacts of anthropogenic activity on ecosystems and thus on species conservation. Its goal is to improve assessments of the impacts of human activity on the environment. We are aware that prognoses have very often proven to be false. It is difficult to impossible to be able to predict with precision how evolution and ecosystems will change in future under anthropogenic influence. This strengthens our resolve to attempt to retain the highest possible degree of scientific integrity and professionalism and not to shy away from expressing the uncertainty of our own ideas and prognoses. We venture prognoses in this book and we will fail. However, we hope that we will be wrong on the right side.

From the lush forests of Appalachia to the frozen tundra of Alaska, and from the tallgrass prairies of the Midwest to the subtropical rainforests of Hawaii, the United States harbors a remarkable array of ecosystems. These ecosystems in turn sustain an exceptional variety of plant and animal life. For species such as salamanders and freshwater turtles, the United States ranks as the global center of diversity. Among the nation's other unique biological features are California's coast redwoods, the world's tallest trees, and Nevada's Devils Hole pupfish, which survives in a single ten-by-seventy-foot desert pool, the smallest range of any vertebrate animal.Precious Heritage draws together for the first time a quarter century of information on U.S. biodiversity developed by natural heritage programs from across the country. This richly illustrated volume not only documents those aspects of U.S. biodiversity that are particularly noteworthy, but also considers how our species and ecosystems are faring, what is threatening them, and what is needed to protect the nation's remaining natural inheritance. Above all, Precious Heritage is a celebration of the extraordinary biological diversity of the United States.
