Fig. 3From: High dietary quality of non-toxic cyanobacteria for a benthic grazer and its implications for the control of cyanobacterial biofilmsMass-specific ingestion rates of L. stagnalis. Ingestion rates (mean + 1 SE; N = 7–8) were determined on the last day of the growth experiment. Means which were found to be significantly different in Tukey post hoc comparisons are labelled with different letters Back to article page
