Book Synopsis Population Ecology of Roosevelt Elk by : Butch Weckerly
Download or read book Population Ecology of Roosevelt Elk written by Butch Weckerly and published by University of Nevada Press. This book was released on 2017-09-27 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Roosevelt elk populate the parks along California’s north coast and comprise the largest land mammals in the parks, some weighing up to 1,200 pounds. They are a stable terrestrial land mammal population, a fixture in the parks, but still require ongoing stewardship and management. In a study spanning more than twenty years, Weckerly made key observations and conducted various investigations under a multitude of ecological conditions. Few authors have dedicated this much time and effort into a single research area. It is a testament to perseverance that his groundbreaking study of the Roosevelt elk was so successful. He was able to document the independent dynamics of several herds of female elk, experience the extinction of one of their subpopulations, and record scientific conclusions in the context of resiliency and redundancy of the elk population. This book will be of considerable interest to those who investigate the ecology of big game animals, including naturalists, hunters, and individuals with particular interest in Redwood State and National Parks. It is an important book that contributes substantially to the persistence and viability of Roosevelt elk in the parks and the surrounding area.
Book Synopsis Influence of a Population Irruption by Roosevelt Elk on a Vegetation Index by : Heath D. Starns

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the factors that influence population growth is central to the study of any species. Large herbivores can influence their food supplies through herbivory. Over 23 years just before and throughout an irruption by a Roosevelt elk population I assessed temporal and spatial patterns of the Normalized Difference Vegetation Index (NDVI). My objectives were to determine if elk herbivory was associated with NDVI and whether the plant community foraged by the irruptive population was tolerant or resistant to elk grazing. Using Landsat 5 Thematic Mapper imagery, I obtained estimates of NDVI for three areas of Redwood National and State Parks, each inhabited by distinct populations of Roosevelt elk. Each population exhibited a different pattern of growth through the time series of the study. One population underwent the irruptive growth pattern while the other two populations did not . Using piece wise regression, I detected temporal changes in NDVI for the area used by the irruptive population that suggested a decline in forage biomass during the end of the dry season but I detected no decline in NDVI at the peak of the growing season. My findings suggest that the area used by the irruptive elk population may have undergone changes in plant community composition favoring plants that were resistant to elk grazing.

Book Synopsis Complex Population Dynamics by : Peter Turchin
Download or read book Complex Population Dynamics written by Peter Turchin and published by Princeton University Press. This book was released on 2013-02-15 with total page 471 pages. Available in PDF, EPUB and Kindle. Book excerpt: Why do organisms become extremely abundant one year and then seem to disappear a few years later? Why do population outbreaks in particular species happen more or less regularly in certain locations, but only irregularly (or never at all) in other locations? Complex population dynamics have fascinated biologists for decades. By bringing together mathematical models, statistical analyses, and field experiments, this book offers a comprehensive new synthesis of the theory of population oscillations. Peter Turchin first reviews the conceptual tools that ecologists use to investigate population oscillations, introducing population modeling and the statistical analysis of time series data. He then provides an in-depth discussion of several case studies--including the larch budmoth, southern pine beetle, red grouse, voles and lemmings, snowshoe hare, and ungulates--to develop a new analysis of the mechanisms that drive population oscillations in nature. Through such work, the author argues, ecologists can develop general laws of population dynamics that will help turn ecology into a truly quantitative and predictive science. Complex Population Dynamics integrates theoretical and empirical studies into a major new synthesis of current knowledge about population dynamics. It is also a pioneering work that sets the course for ecology's future as a predictive science.

Download or read book Elk written by Erwin A. Bauer and published by Voyageur Press (MN). This book was released on 1995 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: A majestic symbol of the great outdoors, elk are widely admired nationwide. They inhabit some of the most rugged and beautiful areas of North America, lending spectacular backdrops to the award-winning photography that illustrates this volume. Like no other book before, Elk offers a complete introduction to the world of the North American elk. From habits to habitats, Erwin Bauer provides extensive coverage including the elk's ancestors and evolution, range, diet, behavior and instincts, physical characteristics, predators, and conservation issues. The Bauers capture elk in every season and in many environments from Yellowstone National Park to the Canadian wilderness. They chronicle the creation of such organizations as the Rocky Mountain Elk Foundation and the National Elk Refuge, and present readers with more than 100 gorgeous color photos, historical black-and-white images, and a range map. Elk is the source for complete details on this regal wild creature.

Book excerpt: California’s Roosevelt (Cervus canadensis rooseveltii) and tule elk (C. c. nannodes) populations have experienced a remarkable recovery after over-hunting and habitat loss nearly extirpated them from the state. Greater clarity of Roosevelt and tule elk habitat selection patterns would help managers continue to effectively support the recovery of these two iconic subspecies. As the manner in which elk populations balance their competing resource needs is unique to each population (Skovlin et al. 2002), I have examined Roosevelt and tule elk habitat selection patterns in separate analyses and present these results in independent chapters. In both cases, I examine the role behavior can play in influencing habitat selection and fitness. Habitat selection models rely on a number of assumptions, which have proven difficult to test, particularly in regards to how behavior relates to perceived habitat suitability and resource availability. In this thesis, I address some of these assumptions by accounting for variation in elk behavior and changing resource conditions. My results demonstrate the effect of behavioral and seasonal resource variation on habitat suitability predictions and its importance for consideration in population management decisions.

Book Synopsis The Elk of North America by : Olaus J. Murie
Download or read book The Elk of North America written by Olaus J. Murie and published by Stackpole Books. This book was released on 2017-09-15 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an outstanding treatise on one of America’s most widely hunted and most important big-game animals. Although thousands of sportsmen take to the field each year in quest of trophies, the perpetuation of elk hunting in America depends entirely upon proper management of the herds. Whether management succeeds or fails in future years will depend upon how well the public understands the problems of the game administrators and of the animals themselves. Everything the sportsman or naturalist would wish to know about the elk in included in this new volume. Habits, food preferences, seasonal movements, anatomy, antler development, and management problems are interestingly and thoroughly discussed. Written by one of America’s greatest field naturalists, this new book has behind it a lifetime spent in intimate study of the subject. Dr. Murie is recognized as the world’s foremost authority on the American elk and his comprehensive research on elk in the Jackson Hole National Monument forms the basis for this book. Everyone interested in America’s wildlife will want this volume in his library. The book is copiously illustrated with half-tone and original line drawings by the author.
