Download or read book Research Techniques in Animal Ecology written by Luigi Boitani and published by Columbia University Press. This book was released on 2000-06-01 with total page 668 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present biodiversity crisis is rife with opportunities to make important conservation decisions; however, the misuse or misapplication of the methods and techniques of animal ecology can have serious consequences for the survival of species. Still, there have been relatively few critical reviews of methodology in the field. This book provides an analysis of some of the most frequently used research techniques in animal ecology, identifying their limitations and misuses, as well as possible solutions to avoid such pitfalls. In the process, contributors to this volume present new perspectives on the collection, analysis, and interpretation of data. Research Techniques in Animal Ecology is an overarching account of central theoretical and methodological controversies in the field, rather than a handbook on the minutiae of techniques. The editors have forged comprehensive presentations of key topics in animal ecology, such as territory and home range estimates, habitation evaluation, population viability analysis, GIS mapping, and measuring the dynamics of societies. Striking a careful balance, each chapter begins by assessing the shortcomings and misapplications of the techniques in question, followed by a thorough review of the current literature, and concluding with possible solutions and suggested guidelines for more robust investigations.

Download or read book Trout written by Sergio Polakof and published by Nova Science Pub Incorporated. This book was released on 2013 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trout are generally considered to be cool, freshwater fish species that belong phylogenetically to the rather young group of fin-rayed or Teleost fishes in the Family Salmonidae. Trout have significant economic, social and scientific importance. This book examines two 'trout', the rainbow trout Oncorhynchus mykiss and the brown trout Salmo trutta. This book came from the editor's interest to bring together some of the major areas that have made 'trout' such an important and enduring model species. The chapters have been carefully crafted by their authors to ensure that they cover as much of the topic as possible including references that support the information.

Download or read book Circle of Fire written by John D. McDermott and published by Stackpole Books. This book was released on 2003-07-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: The year 1865 was bloody on the Plains as various Indian tribes, including the Southern Cheyenne and the Southern Sioux, joined with their northern relatives to wage war on the white man. They sought revenge for the 1864 massacre at Sand Creek, when John Chivington and his Colorado volunteers nearly wiped out a village of Southern Cheyenne and Arapaho. The violence in eastern Colorado spread westward to Fort Laramie and Fort Caspar in southeastern and central Wyoming, and then moved north to the lands along the Wyoming-Montana border.

Book excerpt: "Recognizing the lack of comprehensive information on river ice environmental problems, the National Research Council of Canada's Subcommittee on Hydraulics of Ice Covered Rivers recommended in 1988 that a Task Force be form to investigate the environmental aspects of river ice. The Task Force has assembled this state-of-the-art report in order to document current knowledge and develop recommendations for research. ... This state-of-the-art report comprises contributions by Task Force members and is organized under three major chapters: physical, chemical and biological. The editors have re-arranged original material and inserted new text to enhance the degree of coverage, to maximize consistency among authors' presentations, and to better link the various sections. A subsequent publication "Proceedings of the Workshop on Environmental Aspects of River Ice" will be published following the release of this science report at the workshop of the same name"--Introduction, pages 1-2.

Download or read book Sustaining Marine Fisheries written by National Research Council and published by National Academies Press. This book was released on 1999-03-19 with total page 189 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluctuations and declines in marine fish populations have caused growing concern among marine scientists, fisheries managers, commercial and recreational fishers, and the public. Sustaining Marine Fisheries explores the nature of marine ecosystems and the complex interacting factors that shape their productivity. The book documents the condition of marine fisheries today, highlighting species and geographic areas that are under particular stress. Challenges to achieving sustainability are discussed, and shortcomings of existing fisheries management and regulation are examined. The volume calls for fisheries management to adopt a broader ecosystem perspective that encompasses all relevant environmental and human influences. Sustaining Marine Fisheries offers new approaches to building workable fisheries management institutions, improving scientific data, and developing management tools. The book recommends ways to change current practices that encourage overexploitation of fish resources. It will be of special interest to marine policymakers and ecologists, fisheries regulators and managers, fisheries scientists and marine ecologists, fishers, and concerned individuals.

Download or read book Genetic Management of Fragmented Animal and Plant Populations written by Richard Frankham and published by Oxford University Press. This book was released on 2017 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the greatest unmet challenges in conservation biology is the genetic management of fragmented populations of threatened animal and plant species. More than a million small, isolated, population fragments of threatened species are likely suffering inbreeding depression and loss of evolutionary potential, resulting in elevated extinction risks. Although these effects can often be reversed by re-establishing gene flow between population fragments, managers very rarely do this. On the contrary, genetic methods are used mainly to document genetic differentiation among populations, with most studies concluding that genetically differentiated populations should be managed separately, thereby isolating them yet further and dooming many to eventual extinction Many small population fragments are going extinct principally for genetic reasons. Although the rapidly advancing field of molecular genetics is continually providing new tools to measure the extent of population fragmentation and its genetic consequences, adequate guidance on how to use these data for effective conservation is still lacking. This accessible, authoritative text is aimed at senior undergraduate and graduate students interested in conservation biology, conservation genetics, and wildlife management. It will also be of particular relevance to conservation practitioners and natural resource managers, as well as a broader academic audience of conservation biologists and evolutionary ecologists.

Download or read book Effects of Trawling and Dredging on Seafloor Habitat written by National Research Council and published by National Academies Press. This book was released on 2002-08-09 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concerns over the potential ecological effects of fishing have increased with the expansion of fisheries throughout the marine waters of the United States. Effects of Trawling and Dredging on Seafloor Habitat describes how assessment of fishing impacts depends on gear type, number and location of bottom tows, and the physical and biological characteristics of seafloor habitats. Many experimental studies have documented acute, gear-specific effects of trawling and dredging on various types of habitat. These studies indicate that low mobility, long-lived species are more vulnerable to towed fishing gear than short-lived species in areas where the seabed is often disturbed by natural phenomena. Trawling and dredging may also change the composition and productivity of fish communities dependent on seafloor habitats for food and refuge. The scale of these impacts depends on the level of fishing effort. This volume presents color maps of fishing effort for all regions with significant bottom trawl or dredge fisheries-the first time that such data has been assembled and analyzed for the entire nation.
