Plastic responses to novel environments are biasedtowards phenotype dimensions with high additivegenetic variation

Noble, Daniel WA; Radersma, Reinder; Uller, Tobias


Environmentally induced phenotypes have been proposed to initiate and bias adaptive evolutionary change toward particular directions. The potential for this to happen depends in part on how well plastic responses are aligned with the additive genetic variance and covariance in traits. Using meta-analysis, we demonstrate that plastic responses to novel environments tend to occur along phenotype dimensions that harbor substantial amounts of additive genetic variation. This suggests that selection...[Show more]
