Environmental signals can induce phenotypic changes that span multiple
generations. Along with phenotypic responses that occur during development
(i.e., ‘within-generation’ plasticity), such ‘transgenerational
plasticity’ (TGP) has been documented in a diverse array of taxa spanning
many environmental perturbations. New theory predicts that temporal
stability is a key driver of the evolution of TGP. We tested this
prediction using natural populations of zooplankton from lakes in
Connecticut that span a large gradient in the temporal dynamics of
predator-induced mortality. We reared >120 clones of Daphnia
ambigua from 9 lakes for multiple generations in the presence/absence of
predator cues. We found that temporal variation in mortality selects for
within-generation plasticity while consistently strong (or weak) mortality
selects for increased transgenerational plasticity. Such results provide
the first evidence for local adaptation in TGP and argue that divergent
ecological conditions select for phenotypic responses within and across
generations.
