The loss and fragmentation of natural habitats is one of the major issues in wildlife management and conservation. Habitat "corridors" are sometimes proposed as an important element within a conservation strategy. Examples are given of corridors both as pathways and as habitats in their own right. Includes detailed reviews of principles relevant to the design and management of corridors, their place in regional approaches to conservation planning, and recommendations for research and management.
That is what this book is about. It is a framework for planning, in which habitat is the key to managing wildlife and making forest managers accountable for their actions. This book is based on the collective knowledge of one group of resource professionals and their understanding about how wildlife relate to forest habitats. And it provides a longoverdue system for considering the impacts of changes in forest structure on all resident wildlife.
Small enough to carry in a backpack, this comprehensive guide explores the many diverse natural communities of Michigan, providing detailed descriptions, distribution maps, photographs, lists of characteristic plants, suggested sites to visit, and a dichotomous key for aiding field identification. This is a key tool for those seeking to understand, describe, document, conserve, and restore the diversity of natural communities native to Michigan.
Close to 80 percent of the U.S. population lives in urban areas and depends on the essential ecological, economic, and social benefits provided by urban trees and forests. However, the distribution of urban tree cover and the benefits of urban forests vary across the United States, as do the challenges of sustaining this important resource. As urban areas expand across the country, the importance of the benefits that urban forests provide, as well as the challenges to their conservation and maintenance, will increase. The purpose of this report is to provide an overview of the current status and benefits of America's urban forests, compare differences in urban forest canopy cover among regions, and discuss challenges facing urban forests and their implications for urban forest management.
A leading expert in the emerging field of fire ecology, James Agee analyzes the ecological role of fire in the creation and maintenance of the natural forests common to most of the western U.S. In addition to examining fire from an ecological perspective, he provides insight into its historical and cultural aspects, and also touches on some of the political issues that influence the use of fire. Although the focus of chapters on the ecology of specific forest zones is on the Pacific Northwest, much of the book addresses issues that are applicable to other regions. Illustrations, tables, index.
TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 305: Interaction Between Roadways and Wildlife Ecology summarizes existing information related to roadway planning, design, construction, operation, and maintenance practices being used successfully and unsuccessfully, nationally and internationally, to accommodate wildlife ecology given the challenging background of rapid growth and diminishing natural resources.
Ecological morphology examines the relation between an animal's anatomy and physiology—its form and function—and how the animal has evolved in and can inhabit a particular environment. Within the past few years, research in this relatively new area has exploded. Ecological Morphology is a synthesis of major concepts and a demonstration of the ways in which this integrative approach can yield rich and surprising results. Through this interdisciplinary study, scientists have been able to understand, for instance, how bat wing design affects habitat use and bat diet; how the size of a predator affects its ability to capture and eat certain prey; and how certain mosquitoes have evolved physiologically and morphologically to tolerate salt-water habitats. Ecological Morphology also covers the history of the field, the role of the comparative method in studying adaptation, and the use of data from modern organisms for understanding the ecology of fossil communities. This book provides an overview of the achievements and potential of ecological morphology for all biologists and students interested in the way animal design, ecology, and evolution interact.
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.
The Migration Ecology of Birds, Second Edition covers all aspects of this absorbing subject, including migratory processes, problems of navigation and vagrancy, timing and physiological control of migration, large-scale movement patterns, the effects of recent climate change, the problems that migrants face, and the factors that limit their populations. This book provides a thorough and in-depth review of the state of the science, with the text supplemented by abundant tables, maps and diagrams. Written by a world-renowned avian ecology and migration researcher, this book reveals the extraordinary adaptability of birds to the variable and changing conditions across the globe. This book represents the most updated and detailed review of bird migration, its evolution, ecology and bird physiology. Written in a clear and readable style, it will appeal not only to migration researchers in the field and ornithologists, but to anyone with an interest in this fascinating subject. - Features updated and trending ecological aspects, including various types of bird movements, dispersal and nomadism, and how they relate to food supplies and other external conditions - Contains numerous tables, maps, diagrams, a glossary, and a bibliography of more than 3,000 up-to-date references - Written by an active researcher with a distinguished career in avian ecology, including migration research
