| Title | Conspecific density modulates the effect of predation on dispersal rates |
| Creator | Hammill, Edd Fitzjohn, Richard G. Srivastava, Diane S. |
| Description | Dispersal decisions underlie the spatial dynamics of metacommunities. Prey individuals may disperse to reduce the risk of either predation or starvation, and both of these risks may depend on conspecific density. Surprisingly, there is little theory examining how dispersal rates should change in response to the combined effects of predation and changes in conspecific density. We develop such a model and show that, under certain conditions, predators may induce dispersal at low prey densities... |
