Weak impact of fine-scale landscape heterogeneity on evolutionary potential in Arabidopsis lyrata.

Abstract excerpt

Microhabitat heterogeneity can lead to fine-scale local adaptation when gene flow is restricted, which may be important for the maintenance of genetic variation within populations. This study tested whether microhabitat heterogeneity was associated with trait differences in a population of Arabidopsis lyrata and studied its impact on the genetic variance-covariance (G) matrix. Maternal seed families were...
