In North America Juniperus woodlands occupy approximately 55 million hectares, an area larger than the state of Texas. Various species of Juniperus have been increasing in density and are expanding into associated grasslands, reducing the size of the grasslands. The reason for the Juniperus expansion is highly debated, but has important implications for global change and fire regime studies.
Western North American Juniperus Communities addresses various aspects of the biology, ecology, and management of Juniperus woodlands and savannas, by synthesizing past, current, and proposed...

The Alsea Logging and Aquatic Resources Study, commissioned by the Oregon Legislature in 1959, marked the beginning of four decades of research in the Pacific Northwest devoted to understanding the impacts of forest practices on water quality, water quantity, aquatic habitat, and aquatic organism popu- tions. While earlier watershed research examined changes in runoff and erosion from various land uses, this study was the first watershed experiment to focus so heavily on aquatic habitat and organism response to forest practices. The Alsea Watershed Study, as it came to be known, extended over...

Known as "a dream place for scientists" the Lamto savannas, located on the edge of the Cote d'Ivoire rain forests, are some of the only savannas in the world where ongoing ecological research has endured for over forty years. Drawing from and synthesizing this abundance of research, the book examines the structure, function, and dynamics of the Lamto humid savanna. Beginning with the history of the Lamto ecology station, proceeding on to an overview of the major enivronmental conditions of the site, and specifically examining the integrative view of energy and nutrient fluxes relative to...

In the late 1960s, I worked as a graduate teaching assistant in plant ecology for the late Dr. John Henry Davis at the University of Florida. On one of our visits to the Everglades, he mentioned to me that he had been studying problems of the Everglades since the early 1930s, and that rapid growth in Florida, unless checked, was about to doom the Everglades. He hoped his vegetation survey of the Everglades and his v- etation map could someday be used to help restore the Everglades to some semblance of what it had been prior to the turn of the century. These long-forgotten discussions with Dr....

Molecular biological techniques such as DNA/RNA extraction and purification, and especially the polymerase chain reaction, PCR, are rapidly gaining interest also in related fields, such as microbiology or environmental sciences. They offer new approaches and opportunities for the determination of microbial cells, DNA and RNA from soils, roots, rhizospheres, sediments and aquatic environments. Detailed protocols for these applications are described in this manual.

This book explores the relationship between cultural strategies and their biological outcomes, combining for the first time an ecosystems approach with cultural anthropological, archaeological and evolutionary behavioural concepts. Beginning with resource use and food procurement behaviour, the text examines major subsistence modes, the circumstances and dynamics of large-scale subsistence change, the effect of social differentiation on resource use and the effects of subsistence behaviour on population development and regulation.

Plant-animal interactions have become a focus of ecological research, with the processes of herbivory being of special interest. This volume examines the interactions of leaf-cutting ants with the rainforest vegetation on Barro Colorado Islands in Central America. It is the synthesis of field research on multiple scales extending over a period of several years. This work can serve as a model study summarizing and extending knowledge about herbivorous insect-plant relationships, and the resulting consequences on structural and functional features of tropical ecosystems. The text is an...

Human impact on natural landscapes through urbanization and agricultural expansion are becoming more and more dramatic and are the cause of serious environmental problems. This volume examines the effect of landscape disturbance on plant and animal diversity in the five mediterranean-climate regions of the world. It begins with three introductory chapters broadly reviewing the issues of landscape degradation. Further contributions describe regional land use conflicts in each of the five regions. Landscape disturbance and plant diversity, and landscape disturbance and animal diversity are...

Stimulated by the concern for environmental problems that arose during the 1970s and 1980s, related both to global and national questions of sustain ability, the German government committed itself to advancing ecosystem research as a central component of planning for environment- ally, economically, and socially sound policies and for resource manage- ment during the 21 st century. Ecosystem research has been promoted at institutions spread throughout the country and that are favorably struc- tured to conduct interdisciplinary studies. Research funding is derived from both the federal union...

During recent decades, large-scale effects of pollution on marine estuaries and even entire enclosed coastal seas have become apparent. One of the first regions where this was observed is the Baltic Sea, whereby the appearance of anoxic deep basins, extensive algal blooms and elimination of top predators like eagles and seals indicated effects of both increased nutrient inputs and toxic substances. This book describes the physical, biochemical and ecological processes that govern inputs, distribution and ecological effects of nutrients and toxic substances in the Baltic Sea. Extensive...
