Abstract

Phytoplankton species composition and the availability of potentially limiting resources were investigated in five northern German lakes (Suhrer See, Kellersee, Behler See, $Pluβsee$ , and Krummsee) during spring 1988. Species composition was related to resource ratios to test Tilman's resource-ratio hypothesis. The clearest results were obtained for Aulacoseira spp. Both the time-courses within the lakes and the comparison among the lakes suggest a strong tendency of this genus to become dominant at high Si: light ratios. Fragilariaceae occupied the next position on the Si: light gradient. Such conditions permitted them to become important even when Si:P ratios were quite low. With the onset of stratification diatoms were replaced by flagellates.
