Book Description
This book shows that Holocene human ecosystems are complex adaptive systems in which humans interacted with their environment in a nested series of spatial and temporal scales. Using panarchy theory, it integrates paleoecological and archaeological research from the Eastern Woodlands of North America providing a paradigm to help resolve long-standing disagreements between ecologists and archaeologists about the importance of prehistoric Native Americans as agents for ecological change. The authors present the concept of a panarchy of complex adaptive cycles as applied to the development of increasingly complex human ecosystems through time. They explore examples of ecological interactions at the level of gene, population, community, landscape and regional hierarchical scales, emphasizing the ecological pattern and process involving the development of human ecosystems. Finally, they offer a perspective on the implications of the legacy of Native Americans as agents of change for conservation and ecological restoration efforts today.

Book Description
We live in a changing world; one in which there is much concern and discussion about the topics of global change, loss of biodiversity, and increasing threats to the sustainability of ecosystems. The effects these changes may have on the environment have lead governments and sCientists to make predictions as to how soon changes might occur, where, and with what impact for large and small regions of the Earth. Along with this concern for change in various regions has come the need to understand the role of boundaries between these regions and between landscape elements. Much previous ecological research has dealt with processes within relatively homogeneous landscape units or even the collective characteristics of a composite landscape. Now, however, there is an appreciation that abiotic and biotic components move across heterogeneous landscapes and that the boundaries between these units take on important control functions in this dynamic spatial system. Furthermore, landscape boundaries (or ecotones) are important not only in satisfying life-cycle needs of many organisms, but generally are characterized by high biological diversity.

Book Description
Understand the current concept of wetland and methods for identifying, describing, classifying, and delineating wetlands in the United States with Wetland Indicators - capturing the current state of science's role in wetland recognition and mapping. Environmental scientists and others involved with wetland regulations can strengthen their knowledge about wetlands, and the use of various indicators, to support their decisions on difficult wetland determinations. Professor Tiner primarily focuses on plants, soils, and other signs of wetland hydrology in the soil, or on the surface of wetlands in his discussion of Wetland Indicators. Practicing - and aspiring - wetland delineators alike will appreciate Wetland Indicators' critical insight into the development and significance of hydrophytic vegetation, hydric soils, and other factors. Features Color images throughout illustrate wetland indicators. Incorporates analysis and coverage of the latest Army Corps of Engineers delineation manual. Provides over 60 tables, including extensive tables of U.S. wetland plant communities and examples for determining hydrophytic vegetation.

Book Description
The primary focus of stormwater and urban runoff research during the past twenty-five years has been on the physical description and the chemical quality assessment of runoff events and the design and implementation of the best management practices to control these events. There is a definite need for more effective integration of receiving system issues in the management and regulation of stormwater runoff. This book successfully brings together a diverse group of environmental specialists to address the issues surrounding the assessment, management, and control of stormwater, and more specifically urban runoff, from a receiving system perspective. The book's emphasis on the receiving system is timely, coming during a period when the U.S. Environmental Protection Agency is placing increasing emphasis on wet weather conditions through a new permit program for stormwater runoff and a policy on combined sewer overflows. Stormwater Runoff and Receiving Systems covers biocriteria, assessment of receiving water integrity, and integrated watershed analysis-all aspects of current water quality management programs for both industrial and municipal areas. More than thirty chapters are divided into six sections, offering in-depth discussions on various issues relating to stormwater, urban runoff, and receiving systems; impacts; uncertainty and risk; study design; impact mitigation; and issues analysis. Anyone who deals with regulatory programs requiring stormwater effect assessment including more than sampling and analysis of chemical water quality parameters in effluents will find this reference particularly useful.

Book Description
Mark W. Schwartz Soon after we came into extensive meadows: and I was assured that those meadows continue for a hundred and fifty miles. being in winter drowned lands and marshes. By the dryness of the season they were now beautiful pastures, and here presented itself one of the most delightful prospects I have ever beheld; all low grounds being meadow, and without wood, and all of the high grounds being covered with trees and appearing like islands: the whole scene seemed an elysium. Capt. Thomas Morris. 1791 I am sitting in a 60-mile-an-hour bus sailing over a highway originally laid out for horse and buggy. The ribbon of concrete has been widened and widened until the field fences threaten to topple into the road cuts. In the narrow thread of sod between the shaved banks and the toppling fences grow the relics of what once was Illinois: the prairie.
