Fitness of optimal utilization in semelparous species.

<p>We calculate the value of the fitness of semelparous species with respect to between zero and 1. The vertical dashed line represents the boundary between specialists and generalists as given by Eq.(77). The fitness is always a monotonically increasing function of in the persistent region of the species (). It is remarkable that a large causes individuals to favor risk and increase their fitness. This figure shows the optimal resource utilization actually having advantages over specialists of each of the resources. Parameters are the same as in Fig. 2.
