A linear programming model of herbivore foraging: imprecise, yet successful?

The effects of the sampling error of input variables on the energy-maximizing diets of 14 grassland herbivores were assessed that Belovsky (1986) predicted using a linear programming model of optimal foragging. Monte Carlo simulations showed that the error reported in the estimates of the variables...
