Providing a quantitative assessment of threatened plant populations, that holds for varying management scenarios, has become an essential part of conservation planning. Here, renowned plant ecologists provide information on: major threats to plants, when and where to conduct a plant viability assessment (PVA), what type of PVA to conduct, what alternative options to PVA are available, what information is required for which kind of viability assessment, what attributes of the population in question should be considered, and what the limits of the PVA would be. As such, this volume can be...

Sand dune dynamics play a key role in many arid deserts. This volume provides a thorough analysis of a specific sand dune ecosystem, the Nizzana site in the Middle East's Negev Desert. Describing its climate, as well as its geophysical/geochemical soil properties and ecology, this brilliant work draws out the relationships between the site's ecological and geomorphological processes, based on long-term monitoring, in situ experiments and satellite imagery.

Predation, one of the most dramatic interactions in animals' lives, has long fascinated ecologists. This volume presents carnivores, raptors and their prey in the complicated net of interrelationships, and shows them against the background of their biotic and abiotic settings. It is based on long-term research conducted in the best preserved woodland of Europe's temperate zone. The role of predation, whether limiting or regulating prey (ungulate, rodent, shrew, bird, and amphibian) populations, is quantified and compared to parts played by other factors: climate, food resources for prey,...

Coastal and marine ecosystems, some severely degraded, other still pristine, control rich resources of inshore environments and coastal seas of Latin America's Pacific and Atlantic margins. Conflicts between the needs of the region's nations and diminishing revenues and environmental quality have induced awareness of coastal ecological problems and motivated financial support for restoration and management. The volume provides a competent review on the structure, processes and function of 22 important Latin American coastal marine ecosystems. Each contribution describes the environmental...

In the first volume of this series (edited by D. E. REICHLE) an international panel of experts treated various aspects of ecosystems research, using deciduous forests of the temperate zone as an example. That collection of articles gave a general view of the extent of our present knowledge and established a conceptual framework for the analysis of an ecosystem. The present volume carries on from there, although it serves a different purpose. It is a report on their methods and their experiences by the members of a research group working as a team. Under the direction of Prof. ELLENBERG, one...

After the great achievements in the field of molecular foundations of genetics and protein synthesis, molecular biology undertook the successful deciphering of a number of other important biological problems. By this time ecology in its various branches was far enough advanced to tackle the problems arising at the level of molecular biology. The monograph of Professor Alexandrov, which takes as an example the adaptation of organisms to habitat temperatures, presents a vivid picture of this major ecological problem as viewed at the cellular and molecular levels. As main theme of the book the...

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. Ferdinand de Lesseps was a man straddling two epochs-the romantic utopism of Saint- Simon and the modern world of technocracy. The gigantic project was at its start shouldered by the crowds of tens of thousands of forced laborers still available and ended as a show-piece for modern mechanical earth-moving techniques. The canal builders themselves were still polyhistors in the...

The earth's landscapes are being increasingly impacted by the activities of man. Unfortunately, we do not have a full understanding of the consequences of these disturbances on the earth's productive capacity. This problem was addressed by a group of French and U.S. ecologists who are specialists at levels of integration extending from genetics to the biosphere at a meeting at Stanford, California, sponsored by the National Science Foundation and the Centre National de la Recherche Scientifique. With a few important exceptions it was found at this meeting that most man-induced disturbances of...

The unsaturated zone is the medium through which pollutants move from the soil surface to groundwater. Polluting substances are subjected to complex physical, chemical and biological transformations while moving through the unsaturated zone and their displacement depends on the transport properties of the water-air- porous medium system. Pollution caused by human activities, agriculture, and industry, has brought about a growing interest in the role of the unsaturated zone in groundwater pollution. Due to the complexity and the multidisciplinary nature of the subject, it is being investigated...
