Estimating the capacity of Chamaecrista fasciculata for adaptation to change in precipitation
Author: Peschel, AR; Boehm, EL; Shaw, RG Description: Adaptation through natural selection may be the only means by which small and fragmented plant populations will persist through present day environmental change. A population’s additive genetic variance for fitness (V(A) (W)) represents its immediate capacity to adapt to the environment in which it exists. We evaluated this property for a population of the annual legume Chamaecrista fasciculata through a quantitative genetic experiment in the tallgrass prairie region of the Midwestern United States, where changing climate is predicted to include more variability…
