This volume contains selected papers from the 9th Symposium on Aquatic Oligochaeta, 6-10 October 2003, Wageningen, The Netherlands. 18 contributions deal with the biology of aquatic oligochaetes, and represents a mixture of the fields of taxonomy, anatomy, morphology and physiology, life history, ecology, sludge studies and toxicology. This wide scope is in line with the recent trends in oligochaete research, with a special interest in sludge studies. Research teams from France, Japan, United States, Czech Republic, The Netherlands, Spain, Italy, Germany, Hungary and China present the latest developments on annelid studies and also reflect a balanced mixture of geographical areas, as well as biological topics.

1 2 2,3 MARTÍN H. IRIONDO , JUAN CÉSAR PAGGI , AND MARÍA JULIETA PARMA 2 The great Paraná basin (2,600,000 km) covers a large portion of the Neotropical Realm, extending from the Andes to the Atlantic coast and c- necting the central regions of South America along 2,200 km in a north-south direction. Most of the basin is under subtropical climates, which range from desertic in the west to humid in the east. The Middle Paraná is a broad, complex floodplain extending 600 km in the heart of the interior lowlands of the continent. This system of river channels, shallow lakes, islands, and wetlands remains unoccupied by man and basically unaltered. From a systemic point of view, this area can be considered to be the most important link and collector of the fluvial chain that conveys huge volumes of nutrients, sediments, and salts from the continent to the South Atlantic Ocean. The influence of the Paraná upon the Atlantic is very important. It has been 2 calculated that a sediment deposit 400 m thick and 1 million km in area ac- mulated in the platform and nearby oceanic bottom over the last 2 million years, with a similar amount of dissolved salts contributed by the river to the ocean. This book details the recent advances in the knowledge of the most important segment of the Parana River, organized according to the scientific structure of the National Institute of Limnology of Argentina (INALI-CONICET-UNL).

Modern North American sturgeons and paddlefish are the result of 100 million years of evolution. Once an integral part of aboriginal culture, their numbers were decimated by overfishing and habitat destruction during the past two centuries. This book details the extensive science aimed at helping these remarkable species recover from the brink of extinction, and describes the historical, biological, and ecological importance of North American sturgeon and paddlefish. The text is enhanced by photographs and detailed line drawings. This comprehensive volume will be an invaluable resource for researchers, educators, and consultants, in academic and government settings, who work to further scientific understanding of these fishes. No other single compilation has documented current information in such detail.
