Download or read book Urban Wildlife Habitats written by Lowell W. Adams and published by U of Minnesota Press. This book was released on 1994 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Winter and Spring Staging Ecology of Mallards in South Central Nebraska written by Dennis Gerald Jorde and published by . This book was released on 1981 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large numbers of mallards (Anas platyrhynchos) winter in or migrate through middle and northern latitudes of the midcontinent region in North America. Although an intensively studied species, the wintering and staging ecology of mallards north of traditional areas has received limited attention, leaving waterfowl administrators with limited information for developing management guidelines for mallard populations during these periods of the year. Mallard activity patterns, foraging strategy, and physcial condition were studied on the Platte River in south central Nebraska from mid-December to early April, 1978-80. Local movements, time budgets, food habits, physiology, and energetics during winter and early spring provided an improved perspective of mallard requirements during these stages of the annual cycle. Weather conditions had a major influence on habitat use. Mallard use of the Platte River rose markedly during the mild winter of 1980 and disparity of age and sex ratios was lowe.

Download or read book Urban Wildlife Conservation written by Robert A. McCleery and published by Springer. This book was released on 2014-11-11 with total page 408 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past, wildlife living in urban areas were ignored by wildlife professionals and urban planners because cities were perceived as places for people and not for wild animals. Paradoxically, though, many species of wildlife thrive in these built environments. Interactions between humans and wildlife are more frequent in urban areas than any other place on earth and these interactions impact human health, safety and welfare in both positive and negative ways. Although urban wildlife control pest species, pollinate plants and are fun to watch, they also damage property, spread disease and even attack people and pets. In urban areas, the combination of dense human populations, buildings, impermeable surfaces, introduced vegetation, and high concentrations of food, water and pollution alter wildlife populations and communities in ways unseen in more natural environments. For these ecological and practical reasons, researchers and mangers have shown a growing interest in urban wildlife ecology and management. This growing interest in urban wildlife has inspired many studies on the subject that have yet to be synthesized in a cohesive narrative. Urban Wildlife: Theory and Practice fills this void by synthesizing the latest ecological and social knowledge in the subject area into an interdisciplinary and practical text. This volume provides a foundation for the future growth and understanding of urban wildlife ecology and management by: • Clearly defining th e concepts used to study and describe urban wildlife, • Offering a cohesive understanding of the coupled natural and social drivers that shape urban wildlife ecology, • Presenting the patterns and processes of wildlife response to an urbanizing world and explaining the mechanisms behind them and • Proposing means to create physical and social environments that are mutually beneficial for both humans and wildlife.

Download or read book Bird Species written by Dieter Thomas Tietze and published by Springer. This book was released on 2018-11-19 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: The average person can name more bird species than they think, but do we really know what a bird “species” is? This open access book takes up several fascinating aspects of bird life to elucidate this basic concept in biology. From genetic and physiological basics to the phenomena of bird song and bird migration, it analyzes various interactions of birds – with their environment and other birds. Lastly, it shows imminent threats to birds in the Anthropocene, the era of global human impact. Although it seemed to be easy to define bird species, the advent of modern methods has challenged species definition and led to a multidisciplinary approach to classifying birds. One outstanding new toolbox comes with the more and more reasonably priced acquisition of whole-genome sequences that allow causative analyses of how bird species diversify. Speciation has reached a final stage when daughter species are reproductively isolated, but this stage is not easily detectable from the phenotype we observe. Culturally transmitted traits such as bird song seem to speed up speciation processes, while another behavioral trait, migration, helps birds to find food resources, and also coincides with higher chances of reaching new, inhabitable areas. In general, distribution is a major key to understanding speciation in birds. Examples of ecological speciation can be found in birds, and the constant interaction of birds with their biotic environment also contributes to evolutionary changes. In the Anthropocene, birds are confronted with rapid changes that are highly threatening for some species. Climate change forces birds to move their ranges, but may also disrupt well-established interactions between climate, vegetation, and food sources. This book brings together various disciplines involved in observing bird species come into existence, modify, and vanish. It is a rich resource for bird enthusiasts who want to understand various processes at the cutting edge of current research in more detail. At the same time it offers students the opportunity to see primarily unconnected, but booming big-data approaches such as genomics and biogeography meet in a topic of broad interest. Lastly, the book enables conservationists to better understand the uncertainties surrounding “species” as entities of protection.

Book excerpt: The author presents an illustrated and practical guide to the wide range of urban habitats and the flora and fauna that live within them. The important conservation and management issues presently being faced within our towns and cities are examined. Topics of concern to the conservationalist or habitat manager are explored, including: * the impact and monitoring of pollution * the effects of invasive species * guidelines for the ecological management of sites to enhance their nature conservation value. Urban Habitats is richly illustrated, features up-to-date references and data, and proposes a series of projects.
