Description :
The AA. explore this question with a simple simulation model of the dynamics of a food web in a river with seasonally fluctuating discharge. Components of this river food web spread across a floodplain when it is inundated at high water, and the mobile organisms concentrate back into the channel during reconfinement. The AA. explore the consequences of floodplain width for this model food web by comparing trophic structures that develop when the floodplain is one, ten, and forty times the width of the channel. This model assumes extremely simplified spatial and dynamic properties of both physical and biological components of the ecosystem.
