Available in PDF, EPUB and Kindle. Book excerpt: This open access book reviews the importance of ecological functioning within rangelands considering the complex inter-relationships of production agriculture, ecosystem services, biodiversity, and wildlife habitat. More than half of all lands worldwide, and up to 70% of the western USA, are classified as rangelands—uncultivated lands that often support grazing by domestic livestock. The rangelands of North America provide a vast array of goods and services, including significant economic benefit to local communities, while providing critical habitat for hundreds of species of fish and wildlife. This book provides compendium of recent data and synthesis from more than 100 experts in wildlife and rangeland ecology in Western North America. It provides a current and in-depth synthesis of knowledge related to wildlife ecology in rangeland ecosystems, and the tools used to manage them, to serve current and future wildlife biologists and rangeland managers in the working landscapes of the West. The book also identifies information gaps and serves as a jumping-off point for future research of wildlife in rangeland ecosystems. While the content focuses on wildlife ecology and management in rangelands of Western North America, the material has important implications for rangeland ecosystems worldwide.
Download or read book The Upland and Webless Migratory Game Birds of Texas written by Leonard A. Brennan and published by Texas A&M University Press. This book was released on 2017-02-09 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Authored by some of the state’s top wildlife scientists, The Upland and Webless Migratory Game Birds of Texas presents the most up-to-date and comprehensive information covering twenty-one species of game birds. Ranging from the most well-known, like the Wild Turkey and Mourning Dove, to the marsh-loving rails and other more elusive species, these birds have widespread appeal among both hunters and birders and underscore the diverse challenges facing wildlife scientists, land managers, and conservationists in Texas today. From cultural significance to taxonomy and evolutionary history, this volume provides a wealth of background information on these species. Additionally, the book offers illustrated species accounts, detailed range maps, and information about habitat and management requirements, hunting regulations, and research priorities. Readers will gain a deeper understanding of these game birds and the array of terrestrial and wetland landscapes key to their survival. This will serve as a convenient and thorough reference volume for wildlife biologists and enthusiasts, as well as landowners and hunters.

Download or read book Status Distribution and Principal Foods of Gambel s Quail in Trans Pecos Texas written by Michael Ross Sullins and published by . This book was released on 2006 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aside from a few unpublished documents, virtually no data exists regarding Gambel's quail (Callipepla gambelii) in Texas. Published information on the distribution of Gambel's quail in Texas is ambiguous and food habits are unknown. I initiated this study in order to assess distribution and status, and to determine the principal foods of Gambel's quail in Texas. Distribution occurs from El Paso County southeast to Brewster County below 1,350 m within the Rio Grande valley and intermountain basins along low elevation drainages supporting alluvial plant associations. Small sporadic populations also occur along major drainages on the east and west sides of the Beach and Sierra Diablo Mountains in Hudspeth and Culberson counties, north to Dell City, Texas. Food habits of 392 Gambel's quail were determined for a 24-month period in 2002 to 2004. Twenty foods constituted 91.1 % of the volume of all items consumed. These were: seeds of Salsola kali, Chilopsis linearis, Descurania pinnata, Verbesina enceloides, Mentzelia multifora, Setaria leucopila, Lepidium virginicum, Prosopis glandulosa, Acacia constricta, Acaciia greggii, Lupinus spp. Ambrosia spp., Oligomeris lineofolia, and Lesquerella spp.; fruits of Lycium berlandieri, Rhus microphylla, Condalia warnockii, and Celtis reticulata; green vegetation; and arthropods. Forb seeds were the most consumed food type followed by fruits of woody perennials, seeds of woody perennials, green vegetation, animal material, and grass seeds. Plant species that provided food for GQ also provided critical escape, loafing, and roosting cover. Promoting or protecting existing woody cover is critical to maintaining GQ habitat. Native brush removal should be weighed against loss of GQ habitat and possible reduction in quail numbers.

Book excerpt: "The two reports published here contain elements which contribute substantially to this broader spectrum of Southwestern cultural change. While primarily descriptive in nature, these two site reports, one from the western Kayenta area and one from the margin of the Mesa Verde area and the eastern Kayenta, suggest that the changes which occurred in the more centralized portions of these regions were directly related to what happened on the margins. That, while the site densities and population aggregates may not have been as high, the same factors affected these marginal areas. That conclusion could be expected, but what may not be expected is the differential response which appears to have occurred. After reading these two reports, it appears that it may be possible to discern elements of change in these fringe areas that, once defined, will provide new insight into what happened and why and in what are presently the better known areas of the Southwest. These two papers are important, in sum, not only because they are reports of work in poorly known areas, but because they do provide analyses of fringe areas, they help us to understand the Southwest generally"--From preliminary introduction.

Download or read book Southwestern Desert Resources written by William L. Halvorson and published by University of Arizona Press. This book was released on 2023-01-17 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: The southwestern deserts stretch from southeastern California to west Texas and then south to central Mexico. The landscape of this region is known as basin and range topography featuring to “sky islands” of forest rising from the desert lowlands which creates a uniquely diverse ecology. The region is further complicated by an international border, where governments have caused difficulties for many animal populations. This book puts a spotlight on individual research projects which are specific examples of work being done in the area and when they are all brought together, to shed a general light of understanding the biological and cultural resources of this vast region so that those same resources can be managed as effectively and efficiently as possible. The intent is to show that collaborative efforts among federal, state agency, university, and private sector researchers working with land managers, provides better science and better management than when scientists and land managers work independently.
Download or read book Endangered Species Threatened Convention written by Barnabas Dickson and published by Routledge. This book was released on 2013-11-05 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Convention on International Trade in Endangered Species (CITES) is the best known and most controversial of international conservation treaties. Since it came into force 25 years ago, debate has raged over its most basic assumptions. CITES treats the international trade in wildlife as the most important threat to the continued existence of wild species. It offers a prescription of trade bans and restrictions for endangered species. However, it is now generally acknowledged that for most species habitat loss is a much more significant threat. Some argue that the CITES remedy actually exacerbates the problem by removing the incentive to conserve wildlife habitat. This collection of essays, the first of its kind, charts the controversies and changes within CITES. It provides case studies of the way CITES has dealt with particular species and notes the growing role of the South in shaping the direction of the treaty. It considers the role of sustainable use, the precautionary principle and unilateralism within CITES. Finally, it examines options for the future of CITES. Implicit within a number of the contributions is the recognition that questions of wildlife conservation cannot be divorced from wider issues of land use, development and social justice. This book provides an essential resource for policy makers, practitioners, academics and students concerned with conservation, development and trade.
