|Abstract: ||1. A model is described that evaluates the maximum economic foraging range in
central place foragers by using optimality criteria to discriminate between
foraging sites at different distances from the forager's central place.
2. The basic model can be varied to suit foragers that optimise either their
rate of net energy uptake or their foraging efficiency.
3. The model requires specification of the time and energy budgets of travel and
foraging, and of the rewards obtainable at potential foraging sites.
4. The specific case of bumblebees, whose foraging ranges are poorly known, is
5. Numerical solutions of the model for parameter values that represent
bumblebees and their forage predict economic foraging ranges exceeding several
kilometres. The model demonstrates that economics alone can explain extensive
flight ranges in bees.|
