Cutting across the different seasons, some of the plankters appeared to be "stenotemporal" in that they occur for shorter hours while others are "eurytemporal" in that they occur for longer hours of the day. The principal factors involved appear to be light, temperature, and food in addition to predation and genetic heterogeneity with populations, as well as genetic variation within...
Plankton density in the pond varied significantly with time and depth but not with site, indicating no site-specific differences. ANOVA showed the importance of temporal over spatial variation (P < 0.01). The two components were not significantly different during the rainy season, owing to the effect of cloud cover and precipitation which flushed out the plankton. Temporal variation predominated...
