Summary: Etterson & Shaw (2001)

Etterson & Shaw (2001) described the genetic structure of three populations of the native North American annual legume Chamaecrista fasciculata, under experimental field conditions designed to simulate a warmer, drier climate (as predicted by global climate change models) to evaluate the evolutionary potential of the species. Although they found genetic variance in numerous traits (fecundity, leaf number, leaf thickness, rate of phenological development) under selection, they noted that among-trait correlations antagonistic to the direction of selection may function to limit adaptive evolution. They predict that the rate of evolutionary response in this species is slow than the predicted rate of climate change and could have a negative impact on the species.
