Abstract
In this paper we report the use of an individual-based model of
predator-prey interaction to explore the effects of ``within
generational{''} and ``between generational{''} updating of a system
level variable. We also report the importance of diversity within the
simulated populations. Our findings support those of Grimm and Uchmanski
{[}1994] in regard to the importance of the timing of system level
variables, and support Grimm and Uchmanski and others in regard to the
importance of the level of diversity across the population. The
significance of these findings is emphasized by the fundamental
differences between our model and that of Grimm and Uchmanski in regard
to the assumptions made about resource flow in the system.
