Grants and Contracts Details
I request a Research Experiences for Undergraduates (REU) supplement for NSF DEB-01-0754. The objective of my current award is to examine the importance of genetic covariances as constraints on the evolution of sexual dimorphism, and the potential effects of natural selection on the evolution of genetic covariances. To this end we have established a series of lines of the beetle, Stator limbatus selected for either large or small body size (7 lines per replicate: 2 lines in which we select for large vs. small male size; 2 lines selecting for large vs. small female size; 2 lines in which we select in opposite direction in the two sexes, i.e., selection against the genetic correlation; and a control line; see Figure 1, below). We have completed creating the selected lines, have measured a variety of correlated responses, measured genetic variances and covariances in the antagonistic selection lines, and begun using the selected lines to test various ecological and evolutionary hypotheses. The funded research is progressing well.
