Estimating encounter rates as the first step of sexual selection in the lizard Anolis sagrei.

ABSTRACT: How individuals move through their environment dictates which other individuals they encounter, determining their social and reproductive interactions and the extent to which they experience sexual selection. Specifically, females rarely have the option of mating with all males in a population-they can only choose among the males they encounter. Further, quantifying phenotypic differences between the males that females encounter and those that sire females' offspring lends insight into how social and reproductive interactions shape male phenotypes. We used an explicitly spatio-temporal Markov chain model to estimate the number of potential mates of Anolis sagrei lizards from their movement behaviour, and used genetic paternity assignments to quantify sexual selection on males.
