英文摘要: Both plasticity and genetic differentiation can contribute to phenotypic differences between populations. Using data on non-fitness traits from reciprocal transplant studies, we show that approximately 60% of traits exhibit co-gradient variation whereby genetic differences and plasticity-induced differences between populations are the same sign. In these cases, plasticity is about twice as important as genetic differentiation in explaining phenotypic divergence. In contrast to fitness traits, the amount of genotype by environment interaction is small. Of the 40% of traits that exhibit counter-gradient variation the majority seem to be hyperplastic whereby non-native individuals express phenotypes that exceed those of native individuals. In about 20% of cases plasticity causes non-native phenotypes to diverge from the native phenotype to a greater extent than if plasticity was absent, consistent with maladaptive plasticity. The degree to which genetic differentiation versus plasticity can explain phenotypic divergence varies a lot between species, but our proxies for motility and migration explain little of this variation. © 2020 The Authors.
