The first half of this book is primarily a systematic survey of the snails, beginning with glossaries, keys for identification to genera and a checklist of species. This is followed by a synopsis of species, with brief notes on ecology, distribution and parasites. Relationships are then described between snails and schistosomes and with other parasites. The book goes on to consider the factors affecting snail populations and possible methods for population control.

Tropical diseases pose an increasing problem for US and international travellers who travel to tropical regions. Physicians need to be aware of the wide spectrum of tropical, infectious, and parasitic diseases that patients may be exposed to. This issue of Infectious Disease Clinics includes articles written by global experts and includes topics such as range/classification of tropical diseases, venomous bites and stings, malaria, and bacterial gastrointestinal infections.

This book provides a comprehensive review of the ecology of freshwater bivalves and gastropods worldwide. It deals with the ecology of these species in its broadest sense, including diet, habitat and reproductive biology, emphasising in particular the tremendous diversity of these freshwater invertebrates. Following on from these introductory themes, the author develops a life history model that unifies them, and serves as a basis for reviews of their population and community ecology, including treatments of competition, predation, parasitism and biogeography. Extensively referenced and providing a synthesis of work from the nineteenth century onwards, this book includes original analyses that seek to unify previous work into a coherent whole. It will appeal primarily to professional ecologists and evolutionary biologists, as well as to parasitologists.

This assessment is the first overview of the conservation status of 877 northern African freshwater species belonging to five taxonomic groupsfish, molluscs, dragonflies and damselflies, freshwater crabs and aquatic plantsin accordance with the IUCN regional Red List guidelines. Species at risk of regional extinction are mapped and conservation measures are proposed to reduce the probability of future declines.

The purpose of this book is to provide an overview of the biology of the planorbid snail Biomphalaria glabrata mainly as related to the snail’s role as a host of larval trematodes . This snail is of great importance in medical and economic zoology as a vector of important trematode (fluke) diseases in human and veterinary medicine and in wildlife biology. Moreover, this snail is a useful model for numerous basic studies in biology and chemistry. A book that provides modern coverage of diverse topics from the molecule to the community of this snail as related to larval trematode parasitism is not available. This book should appeal to a wide audience of biologists, ecologists, biochemists, malacologists, parasitologists, public health workers, epidemiologists, and graduate and advanced undergraduate students in biomedical and allied health sciences.

Supplying sustenance for millions of the poorest people in the world, freshwater flora and fauna also contribute to overall economic well-being by means of export commodity trade, tourism, and recreation. As sources of high-quality nutrients, freshwater flora and fauna of edible value represent a viable option for alleviating the problems related to malnutrition in developing and underdeveloped countries. Although the nutritional benefits of freshwater flora and fauna are well known, there has long been a need for a book that supplies an assessment of their nutritional qualities. Well-illustrated with approximately 325 photographs, this book fills that need. Nutritional Freshwater Life details the characteristics of more than 300 species of nutritionally important freshwater animals and plants. The book covers algae and plants, crustaceans (prawns, crayfish, and crabs), mollusks (bivalves and gastropods), fish, and frogs. For each species of freshwater life identified, the book provides a photograph and details its characteristics such as scientific name, common names, habitats, global distribution, nutritional facts, and biological features.

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 certain geographical sense, though it does not possess the slightest significance for many other groups of organisms, ecosystems or geographical and physical features of Africa. The placing of the northern boundary of southern Africa differs in fact strongly per scientific dis cipline and is also influenced by practical considerations regarding the possibilities of scientific work as subordinate to certain political realities and historically grown traditions. This is illustrated, for example, in such works as the Flora of Southern Africa, where the northern boundary of the area is conceived as the northern and eastern political boundaries of South West Africa, South Africa and Swaziland. Botswana, traditionally included in the area covered by the Flora Zambesiaca, thus forms a large wedge in 'Southern Africa'.

Freshwater Biodiversity is a much underestimated component of global biodiversity, both in its diversity and in its potential to act as models for fundamental research in evolutionary biology and ecosystem studies. Freshwater organisms also reflect quality of water bodies and can thus be used to monitor changes in ecosystem health. The present book comprises a unique collection of primary research papers spanning a wide range of topics in aquatic biodiversity studies, and including a first global assessment of specific diversity of freshwater animals. The book also presents a section on the interaction between scientists and science policy managers. A target opinion paper lists priorities in aquatic biodiversity research for the next decade and several reactions from distinguished scientists discuss the relevance of these items from different points of view: fundamental ecology, taxonomy and systematics, needs of developing countries, present-day biodiversity policy at European and at global scales. It is believed that such a platform for the interaction between science and science policy is an absolute necessity for the efficient use of research budgets in the future.
