Night Shift: Expansion of Temporal Niche Use Following Reductions in Predator Density
Figure 1
Effect size plots representing differences in the density (A) and biomass (C) of nocturnal, diurnal, and cathemeral prey fish on reefs at predator-depleted Tabuaeran Atoll relative to predator-heavy Palmyra Atoll.
Positive values represent increases at Tabuaeran. Percentage of surveys (B) in which nocturnal prey fish were sighted at Palmyra and Tabuaeran. Comparisons of the biomass of all large (≥10 kg) diurnal and cathemeral piscivorous predators (D) at both atolls. All values are mean, ±1 SE. Surveys marked with the same letters in each species grouping are not significantly different (after post-hoc correction).
