Zusammenfassung First published in 1980! this important book brings together the results of worldwide research (from the tropics to the Arctic) to determine the relative productivity of different freshwater environments! especially lakes. The investigations are presented in a comparative manner and the underlying causes considered. Inhaltsverzeichnis 1. Introduction L. Tonolli; 2.
