Multivariate adaptation but no increase in competitive ability in invasive Geranium carolinianum L. (Geraniaceae).

Abstract excerpt

Adaptive evolution can affect the successful establishment of invasive species, but changes in selective pressures, loss of genetic variation in relevant traits, and/or altered trait correlations can make adaptation difficult to predict. We used a common-garden experiment to assess trait correlations and patterns of adaptation in the invasive plant, Geranium carolinianum, sampled across 20 populations in its...
