Die Datenmengen, die bei der Modellierung, der Simulation und der Überwachung von Umweltprozessen anfallen, sind heute schon so groß, daß sie nur noch mit Supercomputersystemen in verantwortbaren Zeiten sinnvoll bearbeitet werden können.
Supercomputing is an important science and technology that enables the scientist or the engineer to simulate numerically very complex physical phenomena related to large-scale scientific, industrial and military applications.
Rarely have the many mechanisms that might underlie neural plasticity been examined as explicitly as they are in this broad, lavishly illustrated treatment of plasticity in the somatosensory system.
Starting with the description of meteorological variables in forest canopies and its parameter variations, a numerical three-dimentional model is developed.

All relevant ecological aspects of plankton, especially seasonal changes in the species composition, the role of competition for limiting resources in species replacements, the role of parasitism, predation and competition in seasonal succession are treated in detail considering phytoplankton, zooplankton and bacteroplankton.
Volume 5 presents a detailed survey of the synthesis of pyrethroids and of almost every of the respective patent applications for synthetic pyrethroid active ingredients.
In a very real sense, much of North American physiological plant ecol- ogy began in the Basin and Range and has been researched there over the last four decades.
Environments at Risk is designed as an introductory text and uses case histories of environmental impact assessment to raise issues important in controlling environmental problems.
This book is based on our two books, published in the USSR and translated in a number of other countries Conservation of living nature: problems and perspectives (1983) and The levels of conservation of living nature (1985).
This book is the fruit of a study group on perception and action that worked at the Center for Interdisciplinary Research (ZiP) of the University of Bielefeld, FRG in the academic year 1984-1985.
Ecophysiology of Desert Arthropods and Reptiles starts with a new classification of the world's deserts, based upon the type of precipitation and the effect on their faunas of arthropods and reptiles.
Infectious diseases are transmitted through variousdifferent mechanisms including person to personinteractions, by insect vectors and via verticaltransmission from a parent to an unborn offspring.
A massive phytoplankton bloom, locally termed "e;brown tide"e;, suddenly appeared in Long Island marine bays in 1985, colored the water a dark brown, decimated eelgrass beds and caused catastrophic starvation and recruitment failure of commercially important bay scallop populations.
There is a growing need for cooperation between disciplines, not only to deal with the burning problems of the present, but to study the interaction of societies and their ecosystems in the past.
In July 1989 a symposium was held at the Physiology Department of the Georg August University, G6ttingen, on the physiological, biophysical, biochemical, and technical principles of the coding of chemical substances both in nervous systems and artificial devices.
Individual cell and particle analysis in aquatic sciences isinvolved in many aspects of oceanography and limnology,including optical physics of particles, phytoplanktonphysiology and ecology, marine and aquatic microbiology andfood web interactions.
Behavioural Mechanisms of Food Selection examines animals belonging to diverse trophic groups, from carnivores, herbivores, micro-algal grazers, to filter-feeders and detritus-feeders.
Algal systematists, geologists and evolutionary biologists provide a synthesis of the evolutionary biogeography of red, brown, and green algae of the North Atlantic Ocean also considering their relationships with species and genera in the Arctic and Pacific Oceans as well as other subtropical and tropical seas.
Seasonal Snowpacks examines the processes which control the chemistry of seasonal snowcover and provides detailed information on the biogeographical distribution of snow (e.
