The Ecology of Sex: How the environment shapes the strength of sexual selection and reproductive behaviors


Darwin’s theory of sexual selection accounts for a multitude of gaudy behaviors and traits that make mates more attractive or give them an advantage over a rival. Investigating how the ecological setting can promote or limit the potential for sexual selection is fundamental to our understanding of evolution in sexually reproducing organisms. First, I will discuss my work concerning the influence of the environment on sexual selection in natural populations of dusky pipefish (Syngnathus floridae) – a species with the interesting attributes of male pregnancy and sex-role reversal. Second, I will discuss my ongoing research on the influence of parasites on sexual selection, the major histocompatibility complex (MHC), and mate choice on individual traits in the three-spined stickleback (Gasterosteus aculeatus) – parasitic nematode Camallanus lacustris model system. Finally, I will introduce an initiative investigating the potential for endocrine disrupting compounds and other water-born anthropogenic contaminants to affect behavior and reproduction in fishes. Specifically, I am exploring the effect of the synthetic hormone 17β-estradiol pollution on male reproductive traits and gene expression in three-spined sticklebacks.
