A Volvox colony from a freshwater lake in British Columbia, Canada. Volvox is a genus of green algae that forms colonies of numerous cells. A recent survey of lakes in British Columbia found that richness and composition of zooplankton, phytoplankton, and bacterial communities are regulated independently among lakes and respond to different environmental variables. This photograph originally appeared on the cover of Ecology (88:7) in July of 2007.
