Productivity-Diversity Relationships in Lake Plankton Communities
Figure 1
A conceptual figure of the hypotheses.
a) At small and large scale, the relationships between species richness and nutrient supply are predicted to be unimodal or linear, respectively. b) Biomass production first increases with species richness but saturates at high richness levels. c) The causal relationships between resource availability, species richness, biomass and resource ratio.
