Available in PDF, EPUB and Kindle. Book excerpt: As the vast expanses of natural forests and the great populations of salmonids are harvested to support a rapidly expanding human population, the need to understand streams as ecological systems and to manage them effectively becomes increasingly urgent. The unfortunate legacy of such natural resource exploitation is well documented. For several decades the Pacific coastal ecoregion of North America has served as a natural laboratory for scientific and managerial advancements in stream ecology, and much has been learned about how to better integrate ecological processes and characteristics with a human-dominated environment. These in sightful but hard-learned ecological and social lessons are the subject of this book. Integrating land and rivers as interactive components of ecosystems and watersheds has provided the ecological sciences with impor tant theoretical foundations. Even though scientific disciplines have begun to integrate land-based processes with streams and rivers, the institutions and processes charged with managing these systems have not done so successfully. As a result, many of the watersheds of the Pacific coastal ecoregion no longer support natural settings for environmental processes or the valuable natural resources those processes create. An important role for scientists, educators, and decision makers is to make the integration between ecology and con sumptive uses more widely understood, as well as useful for effective management.

Download or read book Environmental Ecology written by Bill Freedman and published by Academic Press. This book was released on 1995 with total page 638 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like ecology, environmental science is multi- and interdisciplinary. The three major subdisciplines of environmental science are : Population, Resources, Environment. Of the above three major subdisciplines with environmental science, this book is more concerned with the third - the ecological effects of stressors, with particular reference to those associated with the activities of humans. A chapter deals with the use and abuse of biological resources and the emerging field of ecological economics. Some sections deal with environmental impact assessment; ecological monitoring; and the responsibilities of ecologists in environmental issues, environmental education, and the design of sustainable economic systems.

Available in PDF, EPUB and Kindle. Book excerpt: A practical guide that explains how we can design roads that are compatible with populations of small wildlife. Few of us think twice about driving on roads. Yet the very presence of roads and the act of driving on them can impact the ecological infrastructure that supports an animal's daily life. What chance does a turtle have of successfully laying its eggs when it needs to traverse a busy highway? Is it realistic to expect small mammals to breed when an interstate thoroughfare subdivides their population? These are the sorts of challenges faced by small, often slow-moving, animals, challenges that road engineers and ecologists are trying to address. For countless small species, vehicles traveling at high speeds are nothing less than missiles shooting across migration pathways. For too many animals, the danger can lead to the loss of populations, in part because they simply are not programmed to react to traffic. Salamanders faced with a two-lane road between the forest and their aquatic breeding site, for example, will typically cross that road regardless of the congestion. The result can be hundreds of flattened animals in a single night. Roads and Ecological Infrastructure is the first book to focus on reducing conflict between roads and small animals. Highlighting habitat connections and the challenges and solutions from both transportation and ecological perspectives, the volume covers various themes, including animal behavior related to roads and design approaches to mitigate the negative effects of roads on wildlife. The chapter authors—from transportation experts to university researchers—each promote a goal of realistic problem solving. Conceptual and practical, this book will influence the next decade or more of road design in ecologically sensitive areas and should prevent countless unnecessary wildlife fatalities.
