Primary Production and Species Richness in Lake Communities 1997 - 2000

An understanding of the relationship between species richness and productivity is
crucial to understanding biodiversity in lakes. We investigated the relationship between the
primary productivity of lake ecosystems and the number of species for lacustrine
phytoplankton, rotifers, cladocerans, copepods, macrophytes, and fish. Our study includes
two parts: (1) a survey of 33 well-studied lakes for which data on six major taxonomic
groups were available; and (2) a comparison of the effects of short- and long-term
whole-lake nutrient addition on primary productivity and planktonic species richness Dodson,
