This book was released on 2002 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbivory is an important process in plant communities because herbivores have the ability to affect plant abundance, productivity, composition, diversity, and succession. In the grassland ecosystem, the effects of small-mammal herbivores on the plant community are beginning to be understood, but there is little understanding about what factors may influence small-mammal herbivory patterns. This research investigated two factors, wooded edges and plant diversity, that may affect herbivory of native tallgrass prairie seedlings by the small-mammal Microtus pennsylvanicus (the meadow vole). The first study investigated the impact of wooded edges on meadow vole distributions in Iowa tallgrass prairie reconstructions, and their subsequent effect on native prairie vegetation. Voles were less abundant at the wooded edge, resulting in less herbivory on seedlings near the edge. These results indicate that the wooded edges of prairie reconstructions may be refuges for native seedling establishment. The second study investigated the relationship between plant diversity and meadow vole herbivory in native and reconstructed prairies. We found a negative relationship between diversity and herbivory, with decreased herbivory on seedlings as diversity increased. These results suggest that the foraging behavior of voles is not only influenced by diversity, but that diversity may be perpetuated via vole herbivory. In high-diversity prairies, herbivory per species is low, and plant diversity is maintained. However, herbivory per species is great in low-diversity prairies, resulting in the perpetuation, and perhaps accentuation, of low diversity. Together, these studies show that wooded edges and plant diversity have an effect on meadow vole herbivory patterns. Consequently, both of these factors have the potential to change the plant community by altering predation pressure on seedlings. Studying the way in which wooded edges and plant diversity influence vole herbivory has helped our understanding of how prairies function in fragmented ecosystems and how important plant diversity is to prairie ecosystems.

Download or read book Mammals of Colorado Second Edition written by David M. Armstrong and published by University Press of Colorado. This book was released on 2011-05-18 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: Co-published with the Denver Museum of Nature & Science. Thoroughly revised and updated, Mammals of Colorado, Second Edition is a comprehensive reference on the nine orders and 128 species of Colorado's recent native fauna, detailing each species' description, habitat, distribution, population ecology, diet and foraging, predators and parasites, behavior, reproduction and development, and population status. An introductory chapter on Colorado's environments, a discussion of the development of the fauna over geologic time, and a brief history of human knowledge of Coloradan mammals provide ecological and evolutionary context. The most recent records of the state's diverse species, rich illustrations (including detailed maps, skull drawings, and photographs), and an extensive bibliography make this book a must-have reference. Amateur and professional naturalists, students, vertebrate biologists, and ecologists as well as those involved in conservation and wildlife management in Colorado will find value in this comprehensive volume.

Available in PDF, EPUB and Kindle. Book excerpt: Most people do not realize it, but the Midwest has been at the forefront of ecological restoration longer than perhaps any other region in the United States, dating back to the 1930s. Because of its industrial history, agricultural productivity, and natural features such as the Great Lakes, the Midwest has always faced a unique set of ecological challenges. Focusing on six cutting-edge case studies that highlight thirty restoration efforts and research sites throughout the region— Iowa, Indiana, Illinois, Wisconsin, Michigan, Minnesota, and Ohio— editors Christian Lenhart and Peter “Rocky” Smiley Jr. bring together a group of scholars and practitioners to show how midwestern restoration efforts have developed, as well as where they are headed. Whether cleaning up contamination from auto plants in Ohio, or restoring native prairie grasses along the Iowa highway, the contributors uncover a vast network of interested citizens and volunteer groups committed to preserving the region’s environment. This study, intended for researchers, students, and practitioners, also provides an updated synthesis of restoration theory and practice, and pinpoints emerging issues of importance in the Midwest, such as climate change and the increase in invasive species it will bring to the region. Though focusing exclusively on the Midwest, the contributors demonstrate how these case studies apply to restoration efforts across the globe. Contributors: Luther Aadland, David P. Benson, Andrew F.

Book excerpt: This open access book describes the serious threat of invasive species to native ecosystems. Invasive species have caused and will continue to cause enormous ecological and economic damage with ever increasing world trade. This multi-disciplinary book, written by over 100 national experts, presents the latest research on a wide range of natural science and social science fields that explore the ecology, impacts, and practical tools for management of invasive species. It covers species of all taxonomic groups from insects and pathogens, to plants, vertebrates, and aquatic organisms that impact a diversity of habitats in forests, rangelands and grasslands of the United States. It is well-illustrated, provides summaries of the most important invasive species and issues impacting all regions of the country, and includes a comprehensive primary reference list for each topic. This scientific synthesis provides the cultural, economic, scientific and social context for addressing environmental challenges posed by invasive species and will be a valuable resource for scholars, policy makers, natural resource managers and practitioners.
