Table 2.
Correlation of biotic and abiotic parameters in the 24 water reservoirs. (* = significant at p < 0.05; ** = significant at p < 0.01; *** = significant at p < 0.001). Water Temp (Temperature); Air Temp (Air Temperature); Cond (Conductivity); DO (Dissolved Oxygen; Chl a (Chlorophyll a); Secchi (Transparency); Phyto (Phytoplankton concentration cells); Cyano (Cyanobacteria concentration cells); Phyco (Phycocyanin); TN (Total nitrogen); TP (Total phosphorus); MC-LR Water (MC-LR concentration in water); MC-LR Intrac (intracellular MC-LR concentration).
