Ecological Genetics
Traditionally, studies in ecological genetics have involved both field observations and laboratory genetic analyses. Comparisons and cor relations between these two kinds of data have provided valuable in formation on the genetic strategies behind the evolutionary adapta tions of species and their component local populations. Indeed, much of our current understanding of the dynamics of evolutionary pro cesses has come fro~ syntheses of ecological and genetic information. Since the recent discovery of abundant markers in the form of protein polymorphisms, scientific interest in the connections between genetics and ecology has quickened considerably. This volume contains the proceedings of the...

Bivalve Filter Feeders
Bivalve filter-feeding mollusks are important components of coastal ecosystems because they remove large quantities of suspended material from the water and excrete abundant amounts of reactive nutrients. These animals are also major prey for numerous predators including birds, fish, mammals, and invertebrates; furthermore, they are significant food resources for humans. While studies on the organismic and population level have dominated bivalve ecology, the recent focus on the ecosystem roles of filter feeding systems has led to larger-scale investigations. With this approach the specific topics of physiology, grazing, predation, nutrient cycling, physical environment, computer simulation modeling, and environmental management are combined into a meaningful whole.

The Mussel Mytilus
Hardbound. Mussels, of the genus Mytilus are among the commonest of marine molluscs and constitute an important element in the ecology of coastal waters. The mussel's sessile habit makes it suited to cultivation and as filter-feeder an effective concentrator of trace toxic substances. They are thus excellent biomonitoring organisms of coastal water quality. The mussel has been extensively used in experimental studies and a vast body of data on its use in fundamental physiological, biochemical, genetic and toxicological investigations is available. More recently this knowledge has extended into the newer fields of nutrition, environmental monitoring, toxicology, disease, population genetics and biotechnology. This book presents a thorough compilation of state-of-the-art information on mussels in the form of critical review papers written by leading authorities in the field. For workers involved in both research and practical aspects of the biology

Regions at Risk
Human-induced environmental change is to be found throughout the world, but there are areas that scientists consider to be "critical regions" - regions that are particularly vulnerable to or suffering from environmental degradation. In this volume nine such "critical environmental regions" (Amazonia, the Aral Sea basin, the middle mountains of Nepal, Kenya's Ukambani region, the US Southern High Plains, the Mexico Basin, the North Sea, the Ordos Plateau of China, and the eastern Sundaland region of South-East Asia) are examined as case-studies. In chapter one the authors provide a detailed look into the concepts of environmental criticality and endangerment and propose formal definitions. Th...
