Pearson’s and exponential correlations.

Results of Pearson’s and exponential correlations between parameters describing the zooplankton and primary producer communities. *** = p<0.001; ** = p<0.01; * = p<0.05; † = p<0.1; −e = significant negative exponential correlation (see results section for equations). tPhyto = total phytoplankton biomass (µg chl-a L−1), CB = cyanobacterial biomass (µg chl-a L−1), H’Phyto = Shannon-Wiener Index based on phytoplankton biomass, CB fraction = cyanobacterial biomass as % of total phytoplankton biomass, BM ind−1 = biomass per individual (µg), Daph./cal. cop. = ratio of Daphnia to calanoid copepoda, H’Zoo = Shannon-Wiener Index based on zooplankton biomass, Intracell. MC = intracellular microcystin concentration (µg L−1). N = 35.
