The identification of inputs and outputs is the first and probably most important step in testing and analyzing complex systems.

In recent years, a number of books and reviews on the subject of chilling and frost resistance in plants have appeared: all of these publications, however, concentrate principally on the mechanisms of injury and resistance to freezing at the cellular or molecular level.

In view of the increasing problems of waste disposal in the Netherlands, plans were made to pipeline the waste to the Ems-Dollard estuary.

Nitrogen is a key element in ecosystem processes. Aspects of local and global changes in nitrogen in both undisturbed and disturbed conditions are discussed. Emphasis is placed on natural and anthropogenic transfer of nitrogen between ecosystems and also on the interaction of nitrogen with other bioelements.

Topics treated are - methods in multivariate analyses, ordination and classification, - modeling of temporal and spatial aspects of air- and soilborne diseases, - methods to analyse and describe competition among subpopulations, e.g.

The results, published in this book, present the outcome of a cooperative research between plant ecologists, physiologists and population geneticists. The project received generous financial support from the Foundation for Bio logical Research, which is subsidized by the Netherlands Organization for Scientific Research.

El Nino is a meteorological and oceanographic phenomenon, which occurs at irregular intervals in the eastern tropical Pacific. The responses of pinniped populations to the El Nino disturbance of the marine ecosystem also has important implications for the management and conservation of marine mammal populations.

Palms are tropical miracles. Heinrich Heine, the German poet, stated "Unter den Palmen wandert man nicht ungestraft", i.e., one does not wander unpunished under the palms. They will never be without palm nostalgia if and when living somewhere outside this world's tropical and subtropical palm belt.

Aspecial effort was made to evaluate thepotential and actual insight that have been or will bederived from work in related disciplines such as the ecologyof other fungal groups, stream ecology, or populationecology.

Acid rain is a serious international environmental problem. Long-Term Experiments with Acid Rain in Norwegian Forest Ecosystems is a lasting contribution to the literature on acid precipitation, and will be of interest to researchers in ecology, air pollution, forestry and environmental chemistry.

Rocky Mountain National Park was established in 1915, one year before the creation of the National Park Service.

With contributions by numerous experts

Over the past decade there has been considerable interest in the effects of atmospheric deposition on forest ecosystems. It involved intensive measurements of deposition and nutrient cycling at seventeen diverse forested sites in the United States, Canada, and Norway.

Continuous cultures, i.e. Sections onmetabolism and energetics in chemostats, growth models,competition and predator-prey interactions, as well as theapplication of rotifer continuous cultures to ecotoxicologyand their use in aquaculture are included.

It seems almost trite to introduce this book by saying that man has been exploiting the intertidal zone for food for a long time. Similar impressive evidence, going back to at least 100000 years, exists for prehistoric man's consumption of intertidal animals along the South African coast.

This book addresses basic questions concerning the ecological relationships and current conditions of the major river systems in Florida .

Its importance lies in the ubiquity of heterogeneity as a feature of ecological systems and in the number of questions it raises questions to which answers are not readily available. It is devoted to iden tification of the meaning, range of applications, problems, and methodol ogy associated with the study of heterogeneity.

The analysis of stable isotope ratios represents one of the most exciting new technical advances in environmental sciences.

This book addresses the question of what determines species richness in tropical animals by comparing and contrasting the communities of the five major classes of vertebrates in two environments considered to be the most species-rich on Planet Earth - the coral reef and the rainforest.

Our assessment in cludes background information on acidic deposition (Chapter 1), an in-depth discussion of the nature of soil acidity and ecosystem H+ budgets (Chapter 2), and a summary of rates of deposition in the Southeastern U.S. (Chapter 3).

Based on Papers Presented during a 3-Day Symposium Held in Athens, Georgia in October 1984 to Commemorate 50 Years of Research at the Coweeta Hydrological Laboratory

In this volume 19 leading experts offer a timely and coherent overview of the fundamental principles of ecosystem science.

Case Studies of Exosystem Dynamics Under a Spectrum of Land Use-Intensities

The synthesis presented in this volume is a direct outgrowth of our ten-year FORMAP Project (Forest Mapping Across Eastern North America from 20,000 yr B.P. Application of these calibrations to fossil pollen records for interpreting forest history thus represents a fundamental step beyond traditional summaries based upon pollen percentages.
