A Field Guide to Butterflies of the Greater Yellowstone Ecosystem
Yellowstone and Grand Teton National Parks, while mostly noted for grizzly bears, elk, moose, and other large mammals, also host a high species diversity of butterflies, owing to the ecosystem's vast area of pristine habitat. Many of the nearly 120 butterflies described can also be found elsewhere in the Northern Rockies, making the book useful beyond the artificial borders of the public lands. Illustrated with color plates of each species, A Field Guide to Butterflies of the Greater Yellowstone Ecosystem also provides basic information on butterfly anatomy and natural history, as well as the proper way to "catch and release" butterflies—though with a stern reminder that netting butterflies is not permitted in the national parks.
From the Corn Belt to the Gulf
Nutrients from farms in the Mississippi River Basin are the leading cause of the Gulf of Mexico‘s 'Dead Zone,' a 5,000 to 7,000 square mile region where declining oxygen levels are threatening the survival of marine life. From the Corn Belt to the Gulf explores how new agricultural policy can help alleviate this problem, and at the same time improve water quality overall, enhance biodiversity, improve the quality of life for the people who live and work in Corn Belt communities, and relieve downstream flooding. The themes of the book are the far-reaching environmental impacts of Corn Belt agriculture, including associated economic and social effects at multiple spatial scales - and the pot...
The Princeton Guide to Ecology
The Princeton Guide to Ecology is a concise, authoritative one-volume reference to the field's major subjects and key concepts. Edited by eminent ecologist Simon Levin, with contributions from an international team of leading ecologists, the book contains more than ninety clear, accurate, and up-to-date articles on the most important topics within seven major areas: autecology, population ecology, communities and ecosystems, landscapes and the biosphere, conservation biology, ecosystem services, and biosphere management. Complete with more than 200 illustrations (including sixteen pages in color), a glossary of key terms, a chronology of milestones in the field, suggestions for further readi...
The Rural Midwest Since World War II
J.L. Anderson seeks to change the belief that the Midwest lacks the kind of geographic coherence, historical issues, and cultural touchstones that have informed regional identity in the American South, West, and Northeast. The goal of this illuminating volume is to demonstrate uniqueness in a region that has always been amorphous and is increasingly so. Midwesterners are a dynamic people who shaped the physical and social landscapes of the great midsection of the nation, and they are presented as such in this volume that offers a general yet informed overview of the region after World War II. The contributors—most of whom are Midwesterners by birth or residence—seek to better understand ...
Monitoring Ecological Condition in the Western United States
The monitoring of point sources by the Environmental Protection Agency (EPA), the states, and the tribes has documented and helped reduce the levels of chemical stressors affecting our ecosystems. With the controls on point sources reducing chemical contamination, new environmental challenges associated with nonpoint sources have emerged. To adequately deal with these new problems, EPA's Office of Research and Development recognized the need to develop an overall under standing of the condition of our ecological resources, the trends in their condition, and the stressors affecting these systems on a broad scale. Toward this end, the En vironmental Monitoring and Assessment Program (EMAP) was...
Ecological Indicators
Today environmental problems of unprecedented magnitude confront planet earth. The sobering fact is that a whole range of human activities is affecting our global environment as profoundly as the billions of years of evolution that preceded our tenure on Earth. The pressure on vital natural resources in the developing world and elsewhere is intense, and the destruction of tropical forests, wildlife habitat, and other irreplaceable resources, is alarming. Climate change, ozone depletion, loss of genetic diversity, and marine pollution are critical global environmental concerns. Their cumulative impact threatens to destroy the planet's natural resources. The need to address this situation is u...
Ecology of Fragmented Landscapes
Ask airline passengers what they see as they gaze out the window, and they will describe a fragmented landscape: a patchwork of desert, woodlands, farmlands, and developed neighborhoods. Once-contiguous forests are now subdivided; tallgrass prairies that extended for thousands of miles are now crisscrossed by highways and byways. Whether the result of naturally occurring environmental changes or the product of seemingly unchecked human development, fractured lands significantly impact the planet’s biological diversity. In Ecology of Fragmented Landscapes, Sharon K. Collinge defines fragmentation, explains its various causes, and suggests ways that we can put our lands back together. Resear...
