Our work using phenotypic data at the scale of single systems focuses on identifying reproductive isolating barriers – biological features that reduce gene flow between groups of populations. We study several different features including habitat use using niche modeling and migratory behaviour using light-level geolocators. Hybrid zone theory comes in handy here as well.
