Technical water management measures in the inundation region of southern Moravia significantly affected conditions of terrestrial and water ecosystems. Changes in ecological conditions and reaction of biota in the ecosystems of floodplain forests and meadows and regulated watercourses and retention reservoirs were studied within the UNESCO "Man and the Biosphere" programme for several years by a multi-disciplinary team of scientific workers. A broad extent of knowledge from many scientific disciplines enables a deeper insight into complexity of ecological relations after an intervention into landscape to ecologists, water managers, foresters, agronomists and biologists of different specializations.

Dynamic Aquaria is the outgrowth of years of research aimed at studying how to accurately model and construct living ecosystems in mesocosms, microcosms, and aquaria. It is a unique book, presenting scientifically sound information for a growing new area of science--synthetic ecology, or the construction of living ecosystems. At the same time, the authors present thoughtful perspectives on how knowledge gained by creating these smaller ecosystems helps us to understand our wild ecosystems and biosphere as a whole.

Carbon Isotope Techniques

Carbon Isotope Techniques is a hands-on introduction to using carbon isotope tracers in experimental biology and ecology. It provides an easy bench-top reference with many simple-to-follow protocols for studying plants, animals, and soils. The 11C, 12C, 13C, and 14C carbon isotopes are considered and standard techniques are described by established authors. This is a synthetic compilation of well-established techniques.Researchers and students in a wide range of disciplines spanning plant and soil science, agricultural chemistry, forestry, ecology, oceanography, limnology, biogeochemistry, anthropology, and archaeology will find Carbon Isotope Techniques a valuable resource.

This volume contains five papers dealing with a wide range of plant, animal, and soil biological topics.Gray and his colleagues describe the origin and spread of the salt marsh grass Spartina anglica. The result of a hybridization at the close of the last century, this genetically uniform species has been extremely successful in its particular niche and has a fascinating biology.Smith stresses the importance of gene-environment interactions in life-history theory in contrast to the resource constraint emphasis of the optimization approach. Experimental approaches to the subject are also discussed.Chanway and his colleagues examine the evidence for the importance of interactions between plants and micro-organisms in the rhizosphere in determining the outcome of plant competition and the establishment of community structure. Despite scarce evidence, real effects meriting further research do seem to exist.Brundrett also deals with an aspect of ecology in the soil. Most plants seem to have mycorrhizal associates and their importance is now widely appreciated. Much has been learned but more research is needed to determine the beneficial or after effects of mycorrhizae in natural systems.Richter and Babar review the diversity of tropical soils. They are in fact much more variable than is often thought, perhaps because too few ecologists are specialists in soils. Clearly, a proper knowledge and understanding of the many soil types is vital to conservation and development work in the tropics.

Volume 20 of this series deals with a variety of plant and animal ecology topics.**Despite much recent work on herbivory, little attention has been given to insect herbivores active below ground. Brown and Gange describe the ecological adaptations of insects to this abundant but poor quality food resource, and the responses of plants to this potentially very damaging grazing pressure.**Plants living at high altitude must be able to cope with extreme climatic conditions, low carbon dioxide levels, and high radiation doses. Friend and Woodward describe these adaptations and discuss the degree to which they are genetically determined or merely the product of physiological plasticity.**Thomas presents a modular concept of ecology in which modules contain a resource and its associated consumers, and goes on to examine the general principles which may reflect the various mutualisms between organisms in some example fresh water modular systems.**Finally, West examines the microphytic soil crusts of arid and semi-arid soils. Although information on them is currently limited, they are likely to be important in some ecosystems.

Volume 19 in this prestigious series is the second under the new editorial team and benefits once again from their own special interests. The scope of this volume is wide, spanning aspects of plant/insect interactions and arthropod population dynamics to palaeobotany, the evolution of photosynthesis, and marine community ecology. Of particular topical interest is an article on the impact of rising levels of atmospheric carbon dioxide on tree physiology.

This book disseminates the latest information on how humans, animals, insects, and marine life perceive complex odors and tastes. It tells how they use the information from these mixtures to analyze the food they eat, safety of their environment, reproductive status of partners, and how they respond to these complex stimuli.

In the last human generation we have learned that life existed on our earth for more than three billion years, yet man has done more to change the earth and its ability to support life in the last few centuries than preceding life forms have over hundreds of millions of years. And nearly all of these changes were brought about as unforeseen or unconsidered side-effects of our technologies.The editors of this book feel that rather than accepting environmental degradation as the wages of progress, today we are seeing "a more widely accepted idea that concern for the environment is simply good economics and planning."In a series of essays written by environmental, economic, and social scientists from around the world, Changing the Global Environment looks at the ecological problems facing us as we move into the next century and examines possible solutions suggested by such new techniques as remote sensing and the implementation of worldwide computer-based data systems.

This book provides an overview of the major chemical aspects of pesticides giving detailed descriptions of the various groups of pesticides in current use - insecticides, acaricides, nematocides, rodenticides, fungicides and herbicides. The organic syntheses are discussed in detail, as are the biochemical aspects of the effectiveness and mechanisms of action of these chemical agents. The ecological aspects of the use of pesticides - nowadays an important consideration - are also discussed.The main trends of development in the field are also dealt with, e.g. the development of insecticides which present less of a threat to human beings and animals than the ones presently used, whose point of attack is the nervous system. Research is now concentrated on developing chemical compounds which affect the biochemistry or the special behavioural features of insects, instead of acting upon their nervous system. Newly discovered chemicals with selective action which are still in the developmental and experimentational stages are also described.Because of its comprehensive character, the book will be a useful source of information to those engaged in practical work in this field, as well as to researchers in the agricultural sciences.
