Genetics Section Goldsmith, Nicholas [1], Shaw, Ruth [1]. Potential for ongoing adaptation of a native prairie plant. Rapid global change has raised questions about the capacity of species to persist under novel conditions. A population’s persistence depends on the distribution of fitness and the genetic differences responsible for fitness variation. Mean fitness is a measure of a population’s current adaptation to an environment. Additive genetic variance is an estimate of a population’s immediate potential to adapt. Statistical issues have hindered previous assessment of the additive genetic variance for fitness, but aster models with random effects provide a more robust means of calculation. Both mean fitness and additive genetic variance for fitness are unique to a given population in a given environment. Using pedigreed populations of Rudbeckia hirta (Asteraceae, Black Eyed Susan), I aim to examine the current fitness and potential to increase fitness of multiple seed source populations in roadside environments. Results based on a field experiment will be presented. Log in to add this item to your schedule
