Transcriptomic basis of within- and trans-generational predator-induced plasticity in the freshwater snail Physa acuta.

Abstract excerpt

Inducible defences in response to predation risk are a well-known example of adaptive phenotypic plasticity. Although inducible defences have been studied mainly within a generation (within-generational plasticity), there is now clear evidence that ancestral exposure to predation risk can influence the defences expressed by offspring, even if they have not been exposed themselves (transgenerational plasticity)....
