Description:The Middle Paran?? River, one of the largest rivers in the world, is exceptionally rich in fauna and flora and provides researchers a glimpse into an ecosystem yet undisturbed by human civilization. Covering the key aspects of fluvial limnology and ecology related to the river, this book is arranged in the following four sections: The Physical and Chemical Environment; Plant Life; Invertebrate Animal Life; Vertebrate Animal Life. This in-depth and up-to-date review encapsulates 40 years of detailed study by researchers at the Instituto Nacional de Limnolog?a (INALI, CONICET-UNL, Argentina), an internationally renowned institution almost exclusively devoted to the exploration of the Middle Paran??, the most important 600-km-long reach of the river. It is a fascinating read for both specialists and general naturalists alike.
