This condensed volume summarizes updated knowledge on the warm-monomictic subtropical Lake Kinneret, including its geophysical setting, the dynamics of physical, chemical and biological processes and the major natural and anthropogenic factors that affect this unique aquatic ecosystem. This work expands on a previous monograph on Lake Kinneret published in 1978 and capitalizes on the outcome of more than 40 years of research and monitoring activities. These were intensively integrated with lake management aimed at sustainable use for supply of drinking water, tourism, recreation and fishery. The book chapters are aimed at the limnological community, aquatic ecologists, managers of aquatic ecosystems and other professionals. It presents the geographic and geological setting, the meteorology and hydrology of the region, continues with various aspects of the pelagic and the littoral systems. Finally, the last section of the book addresses lake management, demonstrating how the accumulated knowledge was applied in order to manage this important source of freshwater. The section on the pelagic system comprises the heart of the book, addressing the major physical processes, external and internal loading, the pelagic communities (from bacteria to fish), physiological processes and the major biogeochemical cycles in the lake.

Fauna and flora oflakes are an integrative result of regional past history and present environmental factors. In the Lake Kinneret area where Prehistoric Man witnessed the last tectonic readj ustments of the Rift Valley, geological events do not belong only to the remote past but still strongly affect the lacustrine environment. It is therefore necessary to give a detailed picture of the regional background and limnological features of the lake (Parts I and II) before describing its planktic and benthic com munities (Parts III and IV) and the Vertebrate fauna of the lake and its surroundings (Part V). The trophic relationships between communities are beyond the scope of a Monograph and have consequently not been studied in detail but only mentioned occasionally. It is intentional that Man and his penetration into the Kinneret area have been treated on a purely zoological basis. It underlines the fact that Man, as any other living organism, is part of the ecosystem and ruled by its laws and that his activities have an automatic feed back on his environment. However, in contrast with other living organisms, Man is able to 'utilize' the lakes and their watersheds for his benefit if, by appropriate management, he minimizes the damaging influence of his activities. This is the main purpose of the research carried out presently on Lake Kinneret and its watershed and briefly described in Part VI.

Recent studies are proposed to be included to present the actual role together with practical implementation of the ecosystems aimed at water supply, agricultural development, ecological services, lake fishery management, tourism. recreation and nature protection.
