Fig. 1From: High dietary quality of non-toxic cyanobacteria for a benthic grazer and its implications for the control of cyanobacterial biofilmsIncrease of shell height (a) over time and somatic growth rate (b) of L. stagnalis. The snails were fed a diet consisting of single primary producer species or a mixture of all six species (Mixture) in equal biomass (mean + 1 SE; N = 7–8). The dashed line indicates the average of all single algal treatments; means which were found to be significantly different in Tukey post hoc comparisons are labelled with different letters Back to article page
