Download or read book The Wildlife Techniques Manual written by Nova J. Silvy and published by JHU Press. This book was released on 2020-07-28 with total page 1401 pages. Available in PDF, EPUB and Kindle. Book excerpt: The #1 selling wildlife management book for 40 years, now updated for the next generation of professionals and students. Since its original publication in 1960, The Wildlife Techniques Manual has remained the cornerstone text for the professional wildlife biologist. Now fully revised and updated, this eighth edition promises to be the most comprehensive resource on wildlife biology, conservation, and management for years to come. Superbly edited by Nova J. Silvy and published in association with The Wildlife Society, the 50 authoritative chapters included in this work provide a full synthesis of methods used in the field and laboratory. Chapter authors, all leading wildlife professionals, explain and critique traditional and new methodologies and offer thorough discussions of a wide range of relevant topics. To effectively incorporate the explosion of new information in the wildlife profession, this latest edition is logically organized into a 2-volume set: Volume 1 is devoted to research techniques and Volume 2 focuses on pragmatic management methodologies. Volume 1 describes research design and proper analytic methods prior to conducting research, as well as methods and considerations for capturing and handling wild animals and information on identification and marking of captured animals. It also includes new chapters on nutritional research and field sign identification, and on emerging topics, including structured decision-making. Finally, Volume 1 addresses measurements of wildlife abundance and habitat and research on individual animals. Volume 2 begins with a section on the relationship between research and management including public outreach, described in a context that encourages engagement prior to initiation of management. An adaptive management approach is described as a cornerstone of natural resource management, followed by a section on managing landscapes and wildlife populations. The volume also includes new chapters on ethics in wildlife science and conservation, conflict resolution and management, and land reclamation. A standard text in a variety of courses, the Techniques Manual, as it is commonly called, covers every aspect of modern wildlife management and provides practical information for applying the hundreds of methods described in its pages. This deft and thorough update ensures that The Wildlife Techniques Manual will remain an indispensable resource, one that professionals and students in wildlife biology, conservation, and management simply cannot do without.

This book was released on 2021-06-02 with total page 667 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is focused on the marine mammalian groups the Otariidae and the Odobenidae, otherwise known as fur seals, sea lions and the walrus. In 30 chapters, more than 60 authors from 30 institutions and 13 nationalities, discuss a broad suite of topics from maternal care and mating behavior, through play, cognition and personality, to adaptation to life in the Anthropocene. The authors explore the behaviors that have allowed these semi-aquatic mammals to thrive in the marine realm. Many populations have recovered following historical decimation, with interesting evolutionary consequences which are explored. Detailed, selected, individual species descriptions are also provided, showcasing the behavioral diversity of this engaging, adaptive and highly successful group of marine mammals.

Download or read book Behavior and Ecology of the Northern Fur Seal written by Roger L. Gentry and published by Princeton University Press. This book was released on 2014-07-14 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Covering the behavior and ecology of the northern fur seal, this book is a model long-term study of marine mammals, one that tests theory through both observation of undisturbed behavior and manipulative experiments on individuals. Here Roger Gentry draws on nearly two decades of research on three different islands to show how behavior among these seals changes with population size, sex ratio, and environment, to explain the behavior of the population beginning with individuals, and to generalize the results to other members of the eared seal family. In so doing, he offers one of the most comprehensive studies of its kind on any marine mammal species to date. Gentry shows that the species is driven by very different behavioral traits than have been assumed for it in the past. His book analyzes behavior on scales of hours to lifetimes, investigates the mating system, considers processes that underlie the mating system (site fidelity, behavioral estrus, and the development of territoriality), and addresses specific aspects of maternal strategy (female attendance behavior, pup growth, seasonal influences, and the effects of continental shelf width). Gentry contributes to knowledge about marine mammals by providing a very specific basis for interspecies comparisons, and he suggests a link between population trend and environmental regime shifts. He also guides the debate over seal mating systems from an interpretive to an empirical or experimental basis. Originally published in 1997. 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 Report of the Alaska Region and Alaska Fisheries Science Center Northern Fur Seal Tagging and Census Workshop written by Sharon Ruth Melin and published by . This book was released on 2006 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The northern fur seal is listed as 'depleted' in U.S. waters under The Marine Mammal Protection Act of 1972. Under the Marine Mammal Protection Act, a conservation plan is required for all depleted species to assist management and research agencies in recovering the population. In 1993, the Northern Fur Seal Conservation Plan was adopted and has guided northern fur seal research over the past decade. In 2005, the conservation plan was reviewed and updated to reflect the current trends in the population and new biological information. One recommendation of the revised conservation plan was to gather current demographic information on northern fur seal populations. This workshop was convened to outline an approach for a robust marking program that can provide the demographic data necessary to build population models that are needed to assist management in the recovery process for the northern fur seal population. The working group evaluated permanent marking methods including various tagging options, tattoos, hot branding, freeze branding, radio frequency identification tags (RFIDs), natural markings, and new technologies to uniquely identify northern fur seals. The workshop participants also discussed study designs and statistical methods to obtain and analyze demographic data. In addition, the working group examined the current methods of estimating abundance based on direct counts and shear-sampling mark-recapture of pups and discussed alternative methods of population assessment. The working group agreed that a combination of longitudinal and cross-sectional permanent marking of live animals would provide a complete dataset of population parameters for demographic models. The working group determined that in the near-term, external flipper tags are the most feasible method for marking large numbers of northern fur seals. However, tag loss remains a significant problem with the current tags available and a new tag needs to be developed. The working group acknowledged that the future of unique identification of fur seals lies in the development of electronic tags and remote data recorders. This technology is not yet applicable to the unique habitat, life history, distribution, and environmental conditions of pinniped species. The working group discussed the need to encourage manufacturers to develop an electronic tagging system that would be applicable to the needs of the fur seal and sea lion research community. The working group concluded that the current census methods of shear-sampling and direct counts of pups were sufficient but alternative methods for estimating abundance (e.g., medium format photography or infra-red imaging) may be useful in combination with the current methods to refine estimates."--Executive summary.
