Overview

Model demonstrates the role of predator energetics and behaviour in prey interactions within a vertebrate community.

Key Points

  • To explore how predator energetics influence indirect interactions in a vertebrate community.
  • Integrated predator energetics into functional response models
  • Analyzed 20 years of data on prey density and reproductive success
  • Focused on an Arctic tundra vertebrate community
  • Predator energetic balance was closely related to lemming density
  • Threshold of 89 lemmings km −2 is necessary for positive energetic balance
  • Model accurately predicts gull nest success based on predator behaviour
