Southern Africa is certainly not a naturally bounded area so that there are several possibilities for delineating it and concepts about its extent. Wellington* discussed the various possibilities for delineation and suggested that one line stands out more clearly and definitely as a physical boundary than any other, namely the South Equatorial Divide, the watershed between the ZaIre, Cuanza and Rufiji Rivers on the one hand and the Z ambezi, Cunene and Rovuma Rivers on the other. This South Equatorial Divide is indeed a major line of separation for some organisms and is also applicable in a...

Leonard C. Beadle In contrast to the more sta bie oceans, inland waters are, on the geological time scale, short-lived and are subject to great fluctuations in chemical composition and physical features. Very few lakes and rivers have existed continuously for more than a million years, and the life of the majority is to be measured in thousands or less. Earth movements, erosion and long-term climatic changes in the past have caused many of them to appear and disappear. No wonder then that most freshwater organism are especially adapted to great changes and many even to temporary extinction of...

Each year the improvements in communication and transportation, the growing awarness that the resources of this earth are finite, the realization that the population explosion in any part of the world is a concern of all, and the increased economic interdependence of all countries, have increased importance of internationalism as opposed to nationalism. One of the first segments of our society to ignore political and geographic boundaries was that of medicine, particularly in the field of communicable diseases. Valient efforts have been made by some individuals at great personal sacrifice and...

The Pantanal of Pocone provides an in-depth analysis of the ecological relationships in the northern part of the world's largest wetland in a near-natural state. It is the only book available that offers a survey of the flora and fauna of the region, making it particularly interesting for researchers in biodiversity and the biogeography of the Neotropical Region. It stands out among the few books on this vast area of seasonally flooded plains in surveying all major taxa of plants and animals, providing data obtained during a study lasting nearly four years and information available in myriad...

The idea for this book was born at the June 1996 meeting of the IDEAL Steering Committee in Milwaukee, Wisconsin. We had just completed a successful and stimulating special symposium during the annual meeting of the American Society for Limnology and Oceanography, and enthusiasm was running high for the production of a volume that could assemble in one place the scientific findings that were starting to emerge from East Africa. IDEAL, an International Decade for the East African Lakes, had ended one round of field investigations, many of which had been centered on Lake Victoria. As the...

Reservoirs are specific aquatic ecosystems and have complex behaviors of both natural lakes and rivers, regulated significantly by their functions such as flood controlling, hydropower generation, irrigation and fishery. This volume offers a general description of reservoir limnology in tropical and subtropical China. It functions as a window opening to all the aquatic scientists with a main focus on reservoirs in southern China and at the same time also covering several important, large reservoirs such as the Three Gorge Reservoir and Danjiangko Reservoir. Topics discussed are...

Maritime canals dissolve natural barriers to the dispersal of marine organisms, thus providing novel opportunities for natural dispersal, as well as for shipping-mediated transport. The introduction of alien species has proved to be one of the most profound and damaging of anthropogenic deeds - with both ecological and economic costs.
This book is the first to assess the impacts of the world s three principal maritime canals the Kiel, the Panama, the Suez as invasion corridors for alien biota. These three canals differ in their hydrological regimes, the types of biotas they...

The Conference on Tropical Rainforest Research: Current Issues was organised by the University of Brunei Darussalam and The Royal Geographical Society, London, and held in Bandar Seri Begawan, Brunei Darussalam, over 8 days in April 1993. Over 160 participants from 22 countries attended the Conference, which was opened on the 9th April by the Brunei Darussalam Minister for Home Affairs, Yang Berhormat Pehin Orang Kaya Laila Setia Bakti Diraja Dato Laila Utama Haji Awang Isa bin Datu Perdana Menteri Dato Laila Utama Haji Awang Ibrahim. The conference was initially intended to provide a forum...

For a naturalist and limnologist, the Pantanal has the extreme fascination of an "ultima Thule" ofundisturbed and little known wilderness. The scientific world at large is almost unaware of its richness. In an age when scientific research is overstretched because of lack of funds and the hands are full of urgentconservationtasks, it is the amateurtourist who unveils the beauty and the interestof this largest wetland ofthe world. I had the privilege of an outsider, well enough familiarized with Brazil, its language and scientific life, but independent enough of the daily chores of a local...
