Download or read book Population Fluctuations in Rodents written by Charles J. Krebs and published by University of Chicago Press. This book was released on 2013-04-19 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: How did rodent outbreaks in Germany help to end World War I? What caused the destructive outbreak of rodents in Oregon and California in the late 1950s, the large population outbreak of lemmings in Scandinavia in 2010, and the great abundance of field mice in Scotland in the spring of 2011? Population fluctuations, or outbreaks, of rodents constitute one of the classic problems of animal ecology, and in Population Fluctuations in Rodents, Charles J. Krebs sifts through the last eighty years of research to draw out exactly what we know about rodent outbreaks and what should be the agenda for future research. Krebs has synthesized the research in this area, focusing mainly on the voles and lemmings of the Northern Hemisphere—his primary area of expertise—but also referring to the literature on rats and mice. He covers the patterns of changes in reproduction and mortality and the mechanisms that cause these changes—including predation, disease, food shortage, and social behavior—and discusses how landscapes can affect population changes, methodically presenting the hypotheses related to each topic before determining whether or not the data supports them. He ends on an expansive note, by turning his gaze outward and discussing how the research on rodent populations can apply to other terrestrial mammals. Geared toward advanced undergraduate students, graduate students, and practicing ecologists interested in rodent population studies, this book will also appeal to researchers seeking to manage rodent populations and to understand outbreaks in both natural and urban settings—or, conversely, to protect endangered species.

Download or read book Land of Sweeping Plains written by Nicholas S. G. Williams and published by CSIRO PUBLISHING. This book was released on 2015-04-22 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Native temperate grasslands are Australia’s most threatened ecosystems. Grasslands have been eliminated from across much of their former extent and continue to be threatened by urban expansion, agricultural intensification, weed invasion and the uncertain impacts of climate change. Research, however, is showing us new ways to manage grasslands, and techniques for restoration are advancing. The importance of ongoing stewardship also means it is vital to develop new strategies to encourage a broader cross-section of society to understand and appreciate native grasslands and their ecology. Land of Sweeping Plains synthesises the scientific literature in a readily accessible manner and includes a wealth of practical experience held by policy makers, farmers, community activists and on-ground grassland managers. It aims to provide all involved in grassland management and restoration with the technical information necessary to conserve and enhance native grasslands. For readers without the responsibility of management, such as students and those interested in biodiversity conservation, it provides a detailed understanding of native grassland ecology, management challenges and solutions and, importantly, inspiration to engage with this critically endangered ecosystem. Practical, easy to read and richly illustrated, this book brings together the grassland knowledge of experts in ethnobotany, ecology, monitoring, planning, environmental psychology, community engagement, flora and fauna management, environmental restoration, agronomy, landscape architecture and urban design.
Download or read book The Urge to Disperse written by Sheila Newman and published by Lulu.com. This book was released on 2012-11-01 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A biology of land-use planning systems, a political economy of genetic diversity, and a tool for steady state economies, here is a key theory to the mystery of unwanted population growth and unbalanced ecological communities. With a new cross-disciplinary, cross-species theory of population, this book leaps beyond the old demographic transition and predator-prey models. Environmental sociologist, Sheila Newman links a default pattern controlling the population numbers and distribution of human and other species to human land-use planning and political systems. Favorably peer-reviewed by food and population scientist, Prof David Pimentel, and environmental law writer Dr Joseph Wayne-Smith. Incest avoidance and the little-known Westermarck Effect in population algorithms.

Download or read book Using Science to Improve the BLM Wild Horse and Burro Program written by National Research Council and published by National Academies Press. This book was released on 2013-10-04 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Using Science to Improve the BLM Wild Horse and Burro Program: A Way Forward reviews the science that underpins the Bureau of Land Management's oversight of free-ranging horses and burros on federal public lands in the western United States, concluding that constructive changes could be implemented. The Wild Horse and Burro Program has not used scientifically rigorous methods to estimate the population sizes of horses and burros, to model the effects of management actions on the animals, or to assess the availability and use of forage on rangelands. Evidence suggests that horse populations are growing by 15 to 20 percent each year, a level that is unsustainable for maintaining healthy horse populations as well as healthy ecosystems. Promising fertility-control methods are available to help limit this population growth, however. In addition, science-based methods exist for improving population estimates, predicting the effects of management practices in order to maintain genetically diverse, healthy populations, and estimating the productivity of rangelands. Greater transparency in how science-based methods are used to inform management decisions may help increase public confidence in the Wild Horse and Burro Program.

Download or read book Distribution Ecology written by Marcelo Hernán Cassini and published by Springer Science & Business Media. This book was released on 2013-03-02 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together a set of approaches to the study of individual-species ecology based on the analysis of spatial variations of abundance. Distribution ecology assumes that ecological phenomena can be understood when analyzing the extrinsic (environmental) or intrinsic (physiological constraints, population mechanisms) that correlate with this spatial variation. Ecological processes depend on geographical scales, so their analysis requires following environmental heterogeneity. At small scales, the effects of biotic factors of ecosystems are strong, while at large scales, abiotic factors such as climate, govern ecological functioning. Responses of organisms also depend on scales: at small scales, adaptations dominate, i.e. the ability of organisms to respond adaptively using habitat decision rules that maximize their fitness; at large scales, limiting traits dominate, i.e., tolerance ranges to environmental conditions.

Available in PDF, EPUB and Kindle. Book excerpt: This volume investigates how large herbivores not only influence the structure and distribution of the vegetation, but also affect nutrient flows and the responses of associated fauna. The mechanisms and processes underlying the herbivores' behavior, distribution, movement and direct impact on the vegetation are discussed in detail. It is shown that an understanding of plant/animal interactions can inform the management of large herbivores to integrate production and conservation in terrestrial systems.
