Overview
Our research focuses on the evolution of behavior across weird and wonderfully diverse species of birds. This work bridges “muddy boots” experimental fieldwork with a variety of molecular and computational approaches in genetics, genomics, neuroscience, and endocrinology. We have several research foci:
1. Female perspectives in biology. Cultural biases shape our predictions for how and why animals behave the way they do, and female animals have historically been neglected in biological research. We study the evolution of female competition across diverse avian species, ranging from social polyandry to monogamy in shorebirds and songbirds. Critically, hypotheses derived from studying males (i.e. testosterone focus) do not explain interspecific variation in female aggression. We use population genomic and transcriptomic data to evaluate the proximate causes and ultimate consequences of female competition.
2. Global change biology. In the age of the Anthropocene, animals are facing evolutionary unprecedented environmental changes. Sensory pollutants like anthropogenic noise and artificial light at night can alter animal physiology, behavior, and ecology on a rapid timescale. Behavior flexibility and adaptation may lead the way in helping animals respond to novel challenges. We investigate why some individuals and species may be better prepared to face global change.
