Effects of variation in the abundance and distribution of prey on the foraging success of central place foragers

Summary Seabirds and pinnipeds are vulnerable to reductions in prey availability, especially during the breeding season when spatial constraints limit their adaptive capacity. There are growing concerns about the effects of fisheries on prey availability in regions where large commercial fisheries target forage fish. For breeding seabirds and pinnipeds, prey availability depends on a combination of abundance, accessibility, patchiness and...
