Implication

Analysis of energy acquisition and risk avoidance in snowshoe hares and porcupines reveals distinct activity patterns, indicating antipredator strategies influence behavior.

Key Points

  • Distinct activity patterns in winter of snowshoe hares and porcupines reflect their energy-safety trade-offs.
  • Observed activity of snowshoe hares diverged from predictions due to environmental factors and energy balance.
  • Porcupines showed significant individual variation in activity that was independent of environmental factors.
  • Behavioral flexibility differs between species, influenced by antipredator strategies and physiological constraints.
