Book excerpt: The southwestern Amazon basin, centering on the Territory of Rondönia and the State of Acre, is symbolically if not exactly geographically, the Wild Wild West of Brazil's northern rainforest fron tier. In Brazil the name Rondönia evokes exaggerated images of lawlessness, land feuding, and indigent peasants in search of a homestead. Despite the problems and the perception, the region has pushed ahead, in the view of the govern ment, with large-scale deforestation and the establishment of cattle ranches and agricultural farms raising manioc, rice, bananas, and other cash crops. The mining industry has been launched with the exploitation oftin stone, and the recent gold rush has attracted thousands of miners that are sifting alluvial deposits along the rivers for the precious ore. In an energy-short world, the region boasts of its large hydroelectric potential waiting development in the rivers falling off the Brazilian Shield and draining into the Rio Madeira. Planners are optimistic that Rondönia's resources, once developed, will more than justify, at least in this corner of the rainforest frontier, the Economic Conquest ofthe Amazon. Sandwiched between the economic take-off and the dream, however, are the biological resources - the plants and animals - that must serve as sources of energy and food until human dominated ecosystems replace naturaiones. These resources are, ofnecessity, being heavily attacked to support the shaky economy of the region, but they are very poorly understood in terms of potential productivity and proper management.

Available in PDF, EPUB and Kindle. Book excerpt: This paper is concerned specifically with the problems of river fisheries and associated management issues. It deals in particular with the scope for building on traditional practices, through the participation of traditional fishing communities, as a means of improving the quality of river fishery management. The paper reviews the most frequently encountered problems of riverine fisheries such as over-fishing due to population pressure or migration, and artifically induced environmental factors such as dams, pollution and deforestation. It lays stress on the importance of studying fishing communities, as well as strictly biological factors, and presents a four-stage analysis of the evolution of traditional riverine fisheries. Several undesirable consequences of this typical evolution, both on the resource itself and on traditional fishing communities, are identified and illustrated by case studies from the Amazon and the Zambesi. Certain types of traditional management strategies are examined and assessed for their future utility. The current ineffectiveness of many existing government river fisheries management policies is noted, either as a result of lack of resources or because they are inappropriate, often rooted in outdated colonial legislation. The lack of both limited access measures and of participation by local fishing communities are highlighted as major deficiencies. The paper concludes by linking these two features as crucial components of durable river management strategies for the future, although other possibilities for management are also reviewed and assessed. The paper contains a comprehensive bibliography for further reading.

Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the ecology of running waters has come a long way during the past few years. From being a largely descriptive subject, with a few under tones concerned with such things as fisheries, pollution or control of blackflies, it has evolved into a discipline with hypotheses, such as the River Continuum Concept (Vannote et a/. 1980), and even a book suggesting that it offers opportunity for the testing of ecological theory (Barnes & Minshall 1983). However, perusal of the literature reveals that, although some of the very early studies were concerned with large rivers (references in Hynes 1970), the great mass of the work that has been done on running water has been on streams and small rivers, and information on larger rivers is either on such limited topics as fisheries or plankton, scattered among the journals, or not available to the general limnologist. The only exceptions are a few books in this series of publications, such as those on the Nile (Rz6ska 1976), the Volga (Morduckai Boltovskoi 1979) and the Amazon {Sioli 1984), and the recent compendium by Whitton (1984) on European rivers, among which there are a few that rate as large.

This book was released on 2012-12-06 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: This special volume is dedicated to the contributions of women ichthyologists. Three colleagues were selected to represent all women ichthyologists, Ethelwynn Trewavas (ET), Rosemary Lowe-McConnell (Ro) and Eugenie Clark (Genie). All have had distinguished professional careers and have contributed in their own ways to their science. The career of each is highlighted by a personal interview with one of the editors of the volume, a bibliography of their lifetime publications, and a biography of their careers. Questions of historical inequities and current controversies in the treatment of women ichthyologists by their peers are raised and addressed by the women themselves. The personal and professional influences of these three women, and other women ichthyologists, are highlighted. A survey article by Pat Brown brings a number of women ichthyologists to the attention of a broader audience, and points the way for a more comprehensive historical consideration of the accomplishments and contributions of women ichthyologists. The volume continues with 16 solicited and contributed papers. ET's studies of taxonomy and life history are echoed in papers on the taxonomy and systematics of marine angelfishes, and of freshwater bitterlings, a review of reproduction in the North Atlantic ichthyofauna, and a comparison of reproductive styles and systematics of African minnows. Ro's studies on ecology, life history and behaviour are paralleled by papers on growth and metabolism in piranha, the community structure in tide pool fishes, and the social system and reproductive patterns in groupers. Genie's pioneering work on sexual roles and sex change, and her field studies of the behaviour of marine fishes are reflected in papers on gonadal structure and environmental sex determination in brook lamprey, sexual patterns in hawkfish, reproduction and systematics in phallostethids, gonadal structure and systematics in gobiids, reproductive and predator avoidance behaviour in razorfish, early ontogeny of an African mouth brooder, and alternative life histories in killifish.

Available in PDF, EPUB and Kindle. Book excerpt: Feeding Ecology of Fish establishes a comprehensive framework for the variable ecological patterns exemplified by feeding fishes. The author, a former president of the American Fisheries Society, devotes special attention to synthesizing empirical studies in categorizing feeding patterns. This book shows how remarkably adaptable fish can be with regard to selecting food, often from trophic levels not usually occupied. Relying on a thorough literature survey, Feeding Ecology of Fish will be an invaluable reference for both fishery scientists and ecological theorists. Organization by trophic level Emphasis on empirical studies Broad coverage of a diverse field
