Belovsky's model of optimal moose size.
Belovsky's (1978) model for optimal size in moose is applied to red deer. Criticisms are levelled at Belovsky's model. In particular, the equation he derives relating net energy intake to body weight is shown to be fundamentally invalid. Modifications are suggested using existing published information and an analysis of previously unpublished data on red deer stomach size as a function of body weight. I conclude that quantitative predictions of optimal body size are likely to be very difficult as slight changes in the relevant parameters lead to huge changes in predicted optimal weights.
