Correlations and seasonal patterns in grazing and potential phytoplankton growth

Planktonic herbivory has been studied from a variety of perspectives (e.g. LEHMAN & SANDGREN 1985, STERNER 1989, CARPENTER et al. 1991, 1998, STERNER & HESSEN 1994). It is a focal trophic interaction in biomanipulation and a key process for us to understand. However, despite its obvious role in trophic interactions and nutrient cycling, there is no clear way to predict the level of planktonic herbivory in lakes (e.g. CYR & PACE 1992, 1993, CYR 1998). This study had two objectives: to obtain a community-level estimate of grazing in a variety of lakes; and to relate estimates of grazing to various physical, chemical and biological characteristics of the lakes.
