From: Effects of predation pressure and resource use on morphological divergence in omnivorous prey fish
Predation risk in roach of the four lakes studied. Frequency distribution of individual predation risk (from 1 = low to 5 = very high) of roach in the four lakes studied (a-d). Predation score is a log2 (x + 1)-transformed composite of individual fish size and lake-wide piscivory.
