Data and supplementary materials from: Large genetic divergence underpins cryptic local adaptation across ecological and evolutionary gradients

Environmentally covarying local adaptation is a form of cryptic local
adaptation in which the covariance of the genetic and environmental
effects on a phenotype obscures the divergence between locally adapted
genotypes. Here, we systematically document the magnitude and drivers of
the genetic effect (VG) for two forms of environmentally covarying local
adaptation: counter- and cogradient variation. Using a hierarchical
Bayesian meta-analysis, we calculated the overall effect size of VG as
1.05 and 2.13 for populations exhibiting countergradient or cogradient
variation, respectively. These results indicate that the genetic
contribution to phenotypic variation represents a 1.05 to 2.13 standard
deviation change in trait value between the most disparate populations
depending on if populations are expressing counter- or cogradient
variation. We also found that while there was substantial variance among
abiotic and biotic covariates, the covariates with the largest mean
effects were temperature (2.41) and gamete size (2.81). Our results
demonstrate the pervasiveness and large genetic effects underlying
environmentally covarying local adaptation in wild populations and
highlights the importance of accounting for these effects in future
studies.
