Hidden interactions between predators and prey: evolution causes cryptic dynamics in ecology
Date:9/3/2007

e vulnerable bacterial strain showed a typical predator-prey cycle with the phage.

The researchers call this pattern of predatorprey population changes cryptic dynamics, because the rapid evolution of the prey into different genotypes masks the strong interaction between the two species. The implications of this prediction for understanding natural communities are extensive: observations of predator and prey population dynamics cannot always be trusted to be informative about the strength or even the existence of interspecific trophic links because such cryptic evolutionary dynamics may occur in a large fraction of trophic interactions.
