dc.description.abstractThe pattern of genetic variances and covariances among characters, summarized in the additive genetic variance?covariance matrix, G , determines how a population will respond to linear natural selection. However, G itself also evolves in response to selection. In particular, we expect that, over time, G will evolve correspondence with the pattern of multivariate nonlinear natural selection. In this study, we substitute the phenotypic variance?covariance matrix (P ) for G to determine if the pattern of multivariate nonlinear selection in a natural population of Anolis cristatellus , an arboreal lizard from Puerto Rico, has influenced the evolution of genetic variances and covariances in this species. Although results varied among our estimates of P and fitness, and among our analytic techniques, we find significant evidence for congruence between nonlinear selection and P , suggesting that natural selection may have influenced the evolution of genetic constraint in this species.eng
