Download E-books Patterns in Freshwater Fish Ecology PDF

By William J. Matthews

Approximately a decade in the past i started making plans this booklet with the target of summarizing the present physique of data on ecology of freshwater fishes in a manner just like that of H. B. N. Hynes' entire treatise Ecology of operating Waters for streams.

Tim Berra (1981) had summarized in handy map shape the global distribution of all freshwater fish households, and Joe Nelson's 1976 and 1984 variations of Fishes of the realm had seemed. to counterpoint those "big photograph" perspectives of fish distributions, the amount on neighborhood and Evolutionary Ecology of North American Freshwater Fishes, edited by way of David Heins and myself (Matthews and Heins, 1987), had supplied a chance for greater than 30 participants or teams to summarize their paintings on movement fishes (albeit often for warmwater systems).
