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

Ecosystem management has emerged in the past several years as the new paradigm for managing public and private land. It combines the principles of ecosystem-level ecology with the policy requirements of resource and public land management. This collection of selected readings will serve as an introduction to the concepts of biological diversity, ecological process, biotic integrity, and ecological sustainability that underlie ecosystem management.

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.

Whilst agricultural landscapes are products of the local ecosystem and community in which they are situated, they are becoming increasingly affected by the same global issues, and are converging under the dynamics of globalisation. Combining landscape ecological research and an examination of relevant public policy, this book investigates the dynamic relationship between agricultural landscapes and the global change processes, such as urbanisation, by which they are being transformed. Landscape change is analysed in the context of biophysical patterns, market dynamics, and specific public policy frameworks, through a series of case studies from different OECD countries spanning Europe, Asia Pacific and North America. Particular emphasis is placed upon the way that landscapes are changing under differing policies of agricultural subsidy including the EU Common Agricultural Policy. This is an ideal resource for graduate students and researchers in landscape ecology and agriculture as well as policy analysts working in the agricultural sector.

The growth of cities poses ever-increasing challenges for the natural environment on which they impact and depend, not only within their boundaries but also in surrounding peri-urban areas. Landscape ecology – the study of interactions across space and time between the structure and function of physical, biological and cultural components of landscapes – has a pivotal role to play in identifying sustainable solutions. This book brings together examples of research at the cutting edge of urban landscape ecology across multiple contexts that investigate the state, maintenance and restoration of healthy and functional natural environments across urban and peri-urban landscapes. An explicit focus is on urban landscapes in contrast to other books which have considered urban ecosystems and ecology without specific focus on spatial connections. It integrates research and perspectives from across academia, public and private practitioners of urban conservation, planning and design. It provides a much needed summary of current thinking on how urban landscapes can provide the foundation of sustained economic growth, prospering communities and personal well-being.

This volume represents a first attempt at holistically classifying and mapping ecological regions across all three countries of the North American continent. A common analytical methodology is used to examine North American ecology at multiple scales, from large continental ecosystems to subdivisions of these that correlate more detailed physical and biological settings with human activities on two levels of successively smaller units. The volume begins with an overview of North America from an ecological perspective, concepts of ecological regionalization. This is followed by descriptions of the 15 broad ecological regions, including information on physical and biological setting and human activities. The final section presents case studies in applications of the ecological characterization methodology to environmental issues. The appendix includes a list of common and scientific names of selected species characteristic of the ecological regions.

One of the most striking and persistent ways humans dominate Earth is by changing land-cover as we settle a region. Much of our ecological understanding about this process comes from studies of birds, yet the existing literature is scattered, mostly decades old, and rarely synthesized or standardized. The twenty-seven contributions authored by leaders in the fields of avian and urban ecology present a unique summary of current research on birds in settled environments ranging from wildlands to exurban, rural to urban. Ecologists, land managers, wildlife managers, evolutionary ecologists, urban planners, landscape architects, and conservation biologists will find our information useful because we address the conservation and evolutionary implications of urban life from an ecological and planning perspective. Graduate students in these fields also will find the volume to be a useful summary and synthesis of current research, extant literature, and prescriptions for future work. All interested in human-driven land-cover changes will benefit from a perusal of this book because we present high altitude photographs of each study area.

The past decade has seen a huge increase in the interest and attention directed toward sea ducks, the Mergini tribe. This has been inspired, in large part, by the conservation concerns associated with numerical declines in several sea duck species and populations, as well as a growing appreciation for their interesting ecological attributes. Reflecting the considerable research recently conducted on this tribe, Ecology and Conservation of North American Sea Ducks examines the 15 extant species of sea ducks from North America. Chapters are organized conceptually to focus on, compare, and contrast the ecological attributes of the tribe. Experts provide in-depth treatments of a range of topics, including: Population dynamics and genetics Infectious diseases and parasites Breeding costs and cross-seasonal affects Contaminant burdens Foraging behavior and energetics Migration strategies, molt ecology, and habitat affinities and dynamics Breeding systems and reproductive behavior Harvest history The book presents a comprehensive synthesis of sea duck ecology, documents factors that have caused population declines of some species, and provides managers with measures to enhance recovery of depressed populations of sea ducks in North America. Capturing the current state of knowledge of this unique tribe, it provides a benchmark for where we are in conservation efforts and suggests future directions for researchers, managers, students, conservationists, and avian enthusiasts.

Urban Wildlife Habitats was first published in 1994. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. In cities, towns, and villages, between buildings and parking lots, streets and sidewalks, and polluted streams and rivers, there is ever less space for the "natural," the plants and animals that once were at home across North America. In this first book-length study of the subject, Lowell W. Adams reviews the impact of urban and suburban growth on natural plant and animal communities and reveals how, with appropriate landscape planning and urban development, cities and towns can be made more accommodating for a wide diversity of species, including our own. Soils and ground surface, air, water, and noise pollution, space and demographics are among the urban characteristics Adams considers in relation to wildlife. He describes changes in the composition and structure of vegetation, as native species are replaced by exotic ones, and shows how, with spreading urbanization of natural habitats, the diversity of species of plants and animals almost always declines, although the density of a few species increases. Adams contends, however, that it is possible for a wide variety of species to coexist in the metropolitan environment, and he cites a growing interest in the practice of "natural landscaping," which emphasizes the use of native species and considers the structure, pattern, and species composition of vegetation as it relates to wildlife needs. Urban habitats vary from small city parks in densely built downtowns to suburbs with large yards and considerable open space. Adams discusses the opportunities these areas--along with school yards, hospital grounds, cemeteries, individual residences, and vacant lots--provide for judicious wildlife management and for the salutary interaction of people with nature. Lowell W. Adams is vice president of the National Institute for Urban Wildlife in Columbia, Maryland.
