Available in PDF, EPUB and Kindle. Book excerpt: DIVThe decline of bird species in a wide range of North American habitats—forests, prairies, shrublands, mountain regions, marshes, and deserts—has inspired two decades of intense scientific study of bird ecology and conservation. But for professional scientists and amateur birders alike, interpreting the results of these diverse studies is often complex and bewildering. This accessible book pulls together recent research on bird species and habitats to show how basic ecological principles apply in seemingly different situations. Robert A. Askins provides an engaging introduction to bird ecology and concepts of landscape ecology, focusing on such intriguing species as Bachman’s Warbler, Red Crossbill, Mountain Plover, and Marbled Murrelet. Understanding the ancient landscapes of North America and how humans have changed them, Askins says, is essential for devising plans to protect and restore bird populations. In addition to such obvious changes to the landscape as the clearing of forests and plowing of prairies, more subtle changes also dramatically affect birds. Species may disappear when we interrupt natural disturbances by suppressing wildfires or trapping out beaver, or when we disrupt habitat with roads and housing developments. Askins challenges some of the assumptions that underlie current conservation efforts and offers concrete recommendations, based on sound ecological principles, for protecting the rich natural diversity of North America’s birds./div

Download or read book Precious Heritage written by Bruce A. Stein and published by Oxford University Press. This book was released on 2000-03-16 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Urban Bird Ecology and Conservation written by Christopher A. Lepczyk and published by Univ of California Press. This book was released on 2012-10-26 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Now that more than half of the world’s population lives in cities, the study of birds in urban ecosystems has emerged at the forefront of ornithological research. An international team of leading researchers in urban bird ecology and conservation from across Europe and North America presents the state of this diverse field, addressing classic questions while proposing new directions for further study. Areas of particular focus include the processes underlying patterns of species shifts along urban-rural gradients, the demography of urban birds and the role of citizen science, and human-avian interaction in urban areas. This important reference fills a crucial need for scientists, planners, and managers of urban spaces and all those interested in the study and conservation of birds in the world’s expanding metropolises.

Available in PDF, EPUB and Kindle. Book excerpt: The emergence of landscape ecology during the 1980s represents an impor tant maturation of ecological theory. Once enamored with the conceptual beauty of well-balanced, homogeneous ecosystems, ecologists now assert that much of the essence of ecological systems lies in their lumpiness. Patches with differing properties and behaviors lie strewn across the land scape, products of the complex interactions of climate, disturbance, and biotic processes. It is the collective behavior of this patchwork of eco systems that drives pattern and process of the landscape. is not an end point This realization of the importance of patch dynamics in itself, however. Rather, it is a passage to a new conceptual framework, the internal workings of which remain obscure. The next tier of questions includes: What are the fundamental pieces that compose a landscape? How are these pieces bounded? To what extent do these boundaries influence communication and interaction among patches of the landscape? Will con sideration of the interactions among landscape elements help us to under stand the workings of landscapes? At the core of these questions lies the notion of the ecotone, a term with a lineage that even predates ecosystem. Late in the nineteenth century, F. E. Clements realized that the transition zones between plant communi ties had properties distinct from either of the adjacent communities. Not until the emergence of patch dynamics theory, however, has central signif icance of the ecotone concept become apparent.

Download or read book Forest Patches in the Tropical Landscape the Conservation of Migratory Birds written by John Schelhas and published by . This book was released on 1993 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Each year, billions of birds move between the forests of North America & tropical America. Many scientists are concerned with the decline of the magnificent migration systems as habitats are degraded on both ends of the flyways. The Smithsonian Migratory Bird Center is initiating a series of monographs addressing critical issues facing the conservation of migratory birds. Healthy populations of migratory birds depend upon the condition of habitats, which is in turn the result of good stewardship of the land. The SMBC will focus this series on land use & conservation issues that affect both migratory birds & the diversity of life in general. Most importantly, the SMBC recognizes that humans are an inseparable part of the habitat for migratory birds. The papers will present a synthetic, interdisciplinary approach to the biological conservation & social problems involved with the critical land use issues facing migratory bird conservation. The Series first contribution, FOREST PATCHES IN THE TROPICAL LANDSCAPE & THE CONSERVATION OF MIGRATORY BIRDS, will address the conservation of patches of native vegetation in the tropical landscape as a strategy for conserving migratory birds as well as an important component of sustainable land use.

Download or read book Ecology and Conservation of Birds in Urban Environments written by Enrique Murgui and published by Springer. This book was released on 2017-02-10 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides syntheses of ecological theories and overarching patterns of urban bird ecology that have only recently become available. The numerous habitats represented in this book ranges from rows of trees in wooded alleys, to wastelands and remnants of natural habitats encapsulated in the urban matrix. Authored by leading scientists in this emergent field, the chapters explore how the characteristics of the habitat in urban environments influence bird communities and populations at multiple levels of ecological organization and at different spatial and temporal scales, and how this information should be incorporated in urban planning to achieve an effective conservation of bird fauna in urban environments. Birds are among the most conspicuous and fascinating residents of urban neighborhoods and provide urban citizens with everyday wildlife contact all over the world. However, present urbanization trends are rapidly depleting their habitats, and thus knowledge of urban bird ecology is urgently needed if birds are to thrive in cities. The book is unique in its inclusion of examples from all continents (except Antarctica) in an effort to arrive at a more holistic perspective. Among other issues, the individual chapters address the censusing of birds in urban green spaces; the relationship between bird communities and the structure of urban green spaces; the role of exotic plant species as food sources for urban bird fauna; the influence of artificial light and pollutants on bird fauna; trends in long-term urban bird research, and transdisciplinary studies on bird sounds and their effects on humans. Several chapters investigate how our current knowledge of the ecology of urban bird fauna should be applied in order to achieve better management of urban habitats so as to achieve conservation of species or even increase species diversity. The book also provides a forward-looking summary on potential research directions. As such, it provides a valuable resource for urban ecologists, urban ecology students, landscape architects, city planners, decision makers and anyone with an interest in urban ornithology and bird conservation. Moreover, it provides a comprehensive overview for researchers in the fields of ecology and conservation of urban bird fauna.
