There are few achievements of modern man which can compare to the Suez Canal. In Egypt-the land of the most famous wonders of antiquity-the Suez Canal was built as the first technical wonder ofthe industrial revolution.

The basic problem in natural resource development is how to transfer the high productivity and stability characteristic of natural ecosystems to managed ecosystems whose yield is in more useable form.

This volume is concerned with many kinds of links between terrestrial and aquatic ecosystems. These volumes, especially Volume 7 on the evolutionary adaptation of ecosystems to mediter ranean types of climates, are concerned with the ecosystem's strategies of using water, which nature provides on a very seasonal basis.

The acid metabolism of certain succulent plants, now known as Crassulacean Acid Metabolism (CAM) has fascinated plant physiologists and biochemists for the last one and a half centuries.

The purpose of a theoretical model is to use it to explain observed facts and to make predictions beyond the realm of observation which can be verified or denied by further observation.

In 1971 the International Society of Tropical Ecology and the International Association for Ecology held a meeting on Tropical Ecology, with an emphasis on organic production in New Delhi, India.

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.

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.
