Data and R Markdown files for: Estimating the capacity of Chamaecrista fasciculata for adaptation to change in precipitation
<p>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<sub>A</sub>(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 <i>Chamaecrista fasciculata</i> through a quantitative genetic experiment in the tallgrass prairie region of the Midwest USA, where changing climate is predicted to include more variability in rainfall. To reduce incident rainfall, relative to controls receiving ambient rain, we deployed rain exclusion shelters. We found significant V<sub>A</sub>(W) in both treatments. We also detected a significant genotype-by-treatment interaction for fitness which suggests that the genetic basis of the response to natural selection will differ depending on precipitation. For the trait specific leaf area, we detected maladaptive phenotypic plasticity and an interaction between genotype and environment. Selection for thicker leaves was detected with increased precipitation. These results indicate capacity of this population of <i>C. fasciculata</i> to adapt <i>in situ</i> to environmental change.</p>
