Research Interests

giery_researchMy dissertation research focuses on the evolutionary differentiation of sexual selection and communication systems in the wild. I use a model system of mosquitofish populations occurring in natural and human-altered environment to investigate how anthropogenic ecological change might be driving evolutionary divergence in a visual signaling system used in courtship displays. More generally, this research program illustrates how human-mediated ecological change can drive adaptive and non-adaptive evolutionary responses in wild populations. The overarching goal is to raise awareness of the fuller range of consequences that anthropogenic change incurs. Other active research topics include food-web ecology, communication theory, and natural history miscellany.
