The Chavez Lab started field work in the North Cascades of Washington. They are studying hybridization in tree squirrels and trying to understand the role of ecology and behavioral divergence in the evolution of reproductive isolation. The group photo shows part of the field crew, including Gaby Heyer, Sarah Doyle (EEOB undergrad alumnus), and Stephanie Malinich (EEOB undergrad alumnus and MBD collections manager).
