When organisms are faced with new or changing environments, a central
challenge is the coordination of adaptive shifts in many different
phenotypic traits. The actual relationships among traits may facilitate or
constrain evolutionary responses to selection, depending on whether the
direction of selection is aligned or opposed to the pattern of trait
correlations. Attempts to predict evolutionary potential in correlated
traits generally assume that correlations are stable across time and
space; however, increasing evidence suggests that this may not be the
case, and flexibility in trait correlations could bias evolutionary
trajectories. We examined genetic and environmental influences on
variation and covariation in a suite of behavioral traits to understand if
and how flexibility in trait correlations influences adaptation to novel
environments. We tested the role of genetic and environmental influences
on behavioral trait correlations by comparing Trinidadian guppies
(Poecilia reticulata) historically adapted to high- and low-predation
environments that were reared under native and non-native environmental
conditions. Both high- and low-predation fish exhibited increased
behavioral variance when reared under non-native versus native
environmental conditions, and rearing in the non-native environment
shifted the major axis of variation among behaviors. Our findings
emphasize that trait correlations observed in one population or
environment may not predict correlations in another and that
environmentally induced plasticity in correlations may bias behavioral
divergence in novel environments.
