An Analogy for Plankton Interactions
Algal succession in Lake Mendota is similar to that of other eutrophic lakes (Pearsall 1932; Sommer et al. 1986). During spring, high biomass of edible algae (crytophytes, diatoms) is reduced by elevated standing stock of large herbivores, especially Daphnia (Vanni et al., Ch. 13; Luecke et al., Ch. 14). This clear-water phase (CWP) is short-lived, however, and both Daphnia density and fecundity decline as their resource base is overgrazed. Collapse of the Daphnia population may open a window of colonization for cyanophytes which often dominate for the rest of the summer (Carpenter. Ch. 23; Lathrop and Carpenter, Ch. 7).
