This book was released on 2004 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ducks Unlimited's (DU) mission statement is focused on providing for the annual lifecycle needs of migratory waterfowl. The largest impacts to the success and numbers of continental populations are determined by their activities on the breeding grounds. To model and therefore manage habitats and landscapes for ducks (Anas and Aythya spp.) it is necessary to understand several characteristics of their behavior. This research builds a model of nest site selection from nest probability based on remotely sensed data, presence data and minimum threshold theory. The methods used are applicable to other sensor platforms as well as other target species or phenomenon. Using data compression techniques, logistic regression, and spatial statistical functions (Ripley's k-function, a global k-function, and Multiple Response Permutation Procedure) we tested the observed point patterns and developed a point process model to predict nesting patterns. The application of this type of fine resolution da.

Available in PDF, EPUB and Kindle. Book excerpt: Habitat fragmentation often has been cited as a cause for reduced reproductive success of grassland-nesting birds, including ducks, though results of many studies have been equivocal. As remotely sensed habitat data become increasingly available, an increased understanding of how habitat configurations affect demographic parameters will allow wildlife managers to make better decisions about habitat preservation and restoration. We used duck (Anas spp.) nesting data from 15 65-km2 study areas (n=6300 nests) dispersed throughout the aspen (Populus tremuloides) parklands of south-central Canada, to test hypotheses and build models that predict hatching rates and nest-site distributions in relation to landscape features. We constructed separate models using landscape features generated at 3 different spatial extents and using 3 different habitat classification schemes. Generalized linear mixed-modeling techniques were used to model hatching rates, and logistic regression was used to discr.

Available in PDF, EPUB and Kindle. Book excerpt: This book is a comprehensive study of nest-building behavior in birds. A much-needed synthesis of the previously scattered literature on this central aspect of avian biology, it is organized by behavior problems and focuses on evolution as its unifying theme. Originally published in 1984. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.

Download or read book The Natural History of an Arctic Oil Field written by Joe C. Truett and published by Elsevier. This book was released on 2000-06-09 with total page 461 pages. Available in PDF, EPUB and Kindle. Book excerpt: In spite of the harsh conditions that characterize the Arctic, it is a surprisingly fragile ecosystem. The exploration for oil in the Arctic over the past 30 years has had profound effects on the plants and animals that inhabit this frozen clime. The Natural History of an Arctic Oil Field synthesizes decades of research on these myriad impacts. Specialists with years of field experience have contributed to this volume to create the first widely available synopsis of the ecology and wildlife biology of animals and plants living in close association with an actively producing oil field. - First widely available synthesis of arctic oil field ecology and wildlife biology - Concise yet readable treatment of a diverse polar ecosystem - Useful for land managers, policy makers as well as ecologists, and population biologists - Chapters authored by recognized authorities and contributions are peer-reviewed for accuracy and scientific rigor - Illustrations attractively designed to enhance comprehension

Available in PDF, EPUB and Kindle. Book excerpt: Wildlife management specialists and landscape ecologists offer a new perspective on the important intersection of these fields in the twenty-first century. It's been clear for decades that landscape-level patterns and processes, along with the tenets and tools of landscape ecology, are vitally important in understanding wildlife-habitat relationships and sustaining wildlife populations. Today, significant shifts in the spatial scale of extractive, agricultural, ranching, and urban land uses are upon us, making it more important than ever before to connect wildlife management and landscape ecology. Landscape ecologists must understand the constraints that wildlife managers face and be able to use that knowledge to translate their work into more practical applications. Wildlife managers, for their part, can benefit greatly from becoming comfortable with the vocabulary, conceptual processes, and perspectives of landscape ecologists. In Wildlife Management and Landscapes, the foremost landscape ecology experts and wildlife management specialists come together to discuss the emerging role of landscape concepts in habitat management. Their contributions • make the case that a landscape perspective is necessary to address management questions • translate concepts in landscape ecology to wildlife management • explain why studying some important habitat-wildlife relationships is still inherently difficult • explore the dynamic and heterogeneous structure of natural systems • reveal why factors such as soil, hydrology, fire, grazing, and timber harvest lead to uncertainty in management decisions • explain matching scale between population processes and management • discuss limitations to management across jurisdictional boundaries and balancing objectives of private landowners and management agencies • offer practical ideas for improving communication between professionals • outline the impediments that limit a full union of landscape ecology and wildlife management Using concrete examples of modern conservation challenges that range from oil and gas development to agriculture and urbanization, the volume posits that shifts in conservation funding from a hunter constituent base to other sources will bring a dramatic change in the way we manage wildlife. Explicating the foundational similarity of wildlife management and landscape ecology, Wildlife and Landscapes builds crucial bridges between theoretical and practical applications.
