Piscivore-Prey Fish Interactions: Mechanisms behind Diurnal Patterns in Prey Selectivity in Brown and Clear Water
Figure 2
Selectivity of perch (white bars) and roach (grey bars) in one brown and one clear water lake during day (a) and night (b).
The horizontal line at 0 correspond to the null hypothesis of equal selection of prey, values close to 1 represent high prey selection and values close to −1 represent low selection.
