Targeted prey fields determine foraging effort thresholds of a marine diver: Important cues for the sustainable management of fisheries

Understanding functional relationships between seabirds and prey can play an important role in the sustainable management of fisheries that compete for the same resources yet data linking the foraging performance of seabirds directly with concurrent information on prey supplies remain limited. We assess the influence of prey availability on the foraging performance of breeding African penguins Spheniscus demersus using data from instrumented...
