- •
Wildebeest in semi-arid regions face forage variability, heat stress and predation pressure.
- •
Wildebeest coped with heat stress by maximising their activity in the cool hours of the day.
- •
Predation and loss of body condition were avoided by minimising activity at night and in dry seasons, respectively.
- •
Seasonal variations in temperature and light affected the timing of foraging activity.
