Research in the Richards-Zawacki lab lies at the intersection of ecology and evolutionary biology and often (though not always) focuses on amphibians. The questions we ask address (1) how climate and host/pathogen evolution shape the dynamics of wildlife diseases, (2) the effects of changes in climate and landscape on species distributions and diversity, (3) how and when reproductive isolation evolves during speciation, and (4) the natural history and conservation of endangered amphibians.
