Available in PDF, EPUB and Kindle. Book excerpt: The majority of tallgrass prairie has been converted to agriculture over the past two centuries, making it one of the most threatened ecosystems globally. Agricultural conversion of prairie fragmented the landscape, causing declines and local extirpation of many grassland birds. Restoration projects have sought to increase the quality and size of prairie fragments by converting cultivated land back to prairie through revegetation and management with prescribed fire, hypothetically increasing breeding habitat for grassland birds. Bison and other grazers are now being reintroduced to prairie restorations as a final step in the restoration process to increase habitat heterogeneity. The goal of my dissertation was to determine how a recent bison reintroduction at Nachusa Grasslands impacted grassland bird nest success, nest predator composition, and grassland bird detection frequency and to see if it is similar to other studies. I measured daily survivorship rate, visual obstruction of vegetation around nests, and species composition of fourteen species of known avian breeders in areas with and without bison from 2014 to 2018 (Chapter 2). Reduced vegetation obstruction and Brown-headed Cowbird parasitism resulted in decreased nest success overall. Generalist nesters did not differ with respect to any measured variables, including presence of bison. In contrast, facultative and obligate grassland nesting birds occurred at lower nest densities and experienced reduced and more variable nest success in areas with bison. In addition, I constructed artificial nests and placed them at a set density in sites with and without bison and with varying fire frequencies over the same time period (Chapter 3). I found that nest success decreased, and total proportion of depredation events and proportion of Cricetid depredation events increased with prescribed fire. Yearly differences influenced nest success the most and were not related to precipitation during the experiment. I found less nest depredation in the sites with bison, but I found no interaction between fire and grazing. Lastly, I sought to quantify overall species richness and the detection frequency as a proxy for relative abundance of certain grassland bird species that are thought to be impacted by bison grazing (Henslow's Sparrows, Grasshopper Sparrows, Eastern Meadowlarks, Dickcissels, and Brown-headed Cowbirds) from 2016- 2018 (Chapter 4). I used stationary bioacoustics recorders to record the soundscape just after dawn and just before dusk during the summer breeding season in areas with and without bison. I found that species richness and detection frequency of the majority of my target species were not influenced by bison presence. Grasshopper Sparrows were the only species to respond to bison presence and prescribed fire with increase detection frequency in areas burned and grazed. Henslow's Sparrows also showed a species-specific response, but only to prescribed fire, where detection frequency was lower in areas burned. These results are consistent with other research in remnant prairie with both cattle and bison grazing. Site age was the predominant influence on detection frequency of Henslow's Sparrows, Dickcissels, and Eastern Meadowlarks likely due to the vegetation differences in sites that are planted versus remnant sites, with Brown-headed Cowbird abundance only influenced by year. My results suggest that nesting success and detection frequency may be being impacted by bison

Download or read book Prairie Conservation written by Fred B. Samson and published by Island Press. This book was released on 1996-08 with total page 358 pages. Available in PDF, EPUB and Kindle. Book excerpt: The area of native prairie known as the Great Plains once extended from Canada to the Mexican border and from the foothills of the Rocky Mountains to western Indiana and Wisconsin. Today the declines in prairie landscape types, estimated to be as high as 99%, exceed those of any other major ecosystem in North America. The overwhelming loss of landscape and accompanying loss of species constitute a real threat to both ecological and human economic health.Prairie Conservation is a comprehensive examination of the history, ecology, and current status of North American grasslands. It presents for the first time in a single volume information on the historical, economic, and cultural significance of prairies, their natural history and ecology, threats, and conservation and restoration programs currently underway. Chapters cover: environmental history of the Great Plains the economic value of prairie prairie types -- tallgrass, mixed grass, shortgrass, wetlands -- and the ecological processes that sustain each type prairie fauna -- invertebrates, fish and other aquatic creatures, amphibians and reptiles, birds, and mammals conservation programs such as the Great Plains Partnership, Canada's Prairie Conservation Action Plan, the U.S. Prairie Pothole Joint Venture, and others The book brings together knowledge and insights from a wide range of experts to describe and explain the importance of prairies and to position them in the forefront of North American conservation efforts. Praire Conservation is an essential reference for anyone interested in prairie ecology and conservation and will play a critical role in broadening our awareness and understanding of prairie ecosystems.

Book excerpt: This book is open access under a CC BY-NC 2.5 license. This book provides an unprecedented synthesis of the current status of scientific and management knowledge regarding global rangelands and the major challenges that confront them. It has been organized around three major themes. The first summarizes the conceptual advances that have occurred in the rangeland profession. The second addresses the implications of these conceptual advances to management and policy. The third assesses several major challenges confronting global rangelands in the 21st century. This book will compliment applied range management textbooks by describing the conceptual foundation on which the rangeland profession is based. It has been written to be accessible to a broad audience, including ecosystem managers, educators, students and policy makers. The content is founded on the collective experience, knowledge and commitment of 80 authors who have worked in rangelands throughout the world. Their collective contributions indicate that a more comprehensive framework is necessary to address the complex challenges confronting global rangelands. Rangelands represent adaptive social-ecological systems, in which societal values, organizations and capacities are of equal importance to, and interact with, those of ecological processes. A more comprehensive framework for rangeland systems may enable management agencies, and educational, research and policy making organizations to more effectively assess complex problems and develop appropriate solutions.

Available in PDF, EPUB and Kindle. Book excerpt: Ecology of the Shortgrass Steppe: A Long-Term Perspective summarizes and synthesizes more than sixty years of research that has been conducted throughout the shortgrass region in North America. The shortgrass steppe was an important focus of the International Biological Program's Grassland Biome project, which ran from the late 1960s until the mid-1970s. The work conducted by the Grassland Biome project was preceded by almost forty years of research by U.S. Department of Agriculture researchers-primarily from the Agricultural Research Service-and was followed by the Shortgrass Steppe Long-Term Ecological Research project. This volume is an enormously rich source of data and insight into the structure and function of a semiarid grassland.

This book was released on 1988 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Adaptive Strategies and Population Ecology of Northern Grouse" was first published in 1988. Minnesota Archive Editions uses digital technology to make long-unavailable books once again accessible, and are published unaltered from the original University of Minnesota Press editions. This book is at once a major reference to the species of grouse that inhabit North America and the Holarctic and a synthesis of all the available data on their ecology, sociobiology, population dynamics, and management. The book undertakes to answer two long-standing questions in population ecology: what actually regulates the numbers within a population, and what are the breeding and survival strategies evolved in this northern environment? For Volume I, editors Arthur T. Bergerud and Michael W. Gratson have drawn together their own work and that of colleagues in North America, Iceland, and Norway--in all, eleven research studies, averaging six years' duration, on eight species of grouse. These studies deal with the blue and ruffed grouse of the forest habitat; the sharp-tailed grouse, prairie chicken, and sage grouse of the prairie or steppe; and the white-tailed, rick, and willow ptarmigan found in alpine and arctic tundras. The authors describe the rich repertoire of behavior patterns developed by the hen and the cock to achieve their two primary objectives--first, to stay alive, and then to breed. Volume II, primarily the work of Bergerud, synthesizes the evidence in Volume I and in the grouse research literature from a theoretical perspective. Several potentially controversial sociobiological hypotheses are advanced to account for flocking behavior, migration, dispersal, roosting and feeding behavior, mate choice and mating systems. The demographic analysis provides new insights into cycles of abundance, the limitation of numbers, and the demographic factors that determine densities. The contributors, besides Bergerud and Gratson: R.C. Davies, A. Gardarson, J.E. Hartzler, R.A. Huempfner, D.A. Jenni, D.H. Mossop, S. Myrberget, R.E. Page, R.K. Schmidt, W.D. Svedarsky, and J.R.
