Description: While diatoms remain the most abundant primary producer in the pelagic Laurentian Great Lakes, long-term time series data indicate that other algae, such as flagellates, are gradually taking their place. Drivers appear to be related to climate, invasive species, and nutrients. The prevailing trend toward cyanobacterial blooms in shallower waters is also concerning, but it is clear through clique analysis that these cyanobacteria are not alone -- diatoms and other algae are there, too! Do they play some partnering role? Maybe you know.

Audience: This talk is directed at ecologists and generalists interested in understanding how lakes are changing over time, and the importance of those changes.
