Studying the effects of prey distribution on predator behaviour is complex in systems where there are multiple prey species. The role of prey density in predator behaviour is rarely studied in closed ecosystems of one predator species and one prey species, despite these being an ideal opportunity to...

Studying the effects of prey distribution on predator behaviour is complex in systems where there are multiple prey species. The role of prey density in predator behaviour is rarely studied in closed ecosystems of one predator species and one prey species, despite these being an ideal opportunity to test these hypotheses.

We use resource selection models to compare prey density in areas utilised by predators (obtained from fine-scale GPS telemetry data) to prey density at randomly generated points (pseudo-absences) throughout the available area.
