Research summary

Research in the O'Donnell lab addresses questions at multiple levels of biological organization (individuals, social groups, and ecological assemblages) and across levels of causation: genetics, organismal and social physiology, nervous system development and plasticity, and the evolution of brains and behavior.

The lab works with a diverse array of study organisms: social insects (army ants, seed-harvesting ants, paper wasps, termites), social spiders, wood roaches, desert-dwelling solitary bees and social isopods, and Neotropical birds.

Current projects include analysis of brain size as a determinant of body structure, using social behavior evolution in spiders to test social brain hypotheses, evolution and ecology of thermal physiology in desert ants, chemical basis of division of labor in paperwasps, neurobiology of biparental care in isopods, and sensory neurobiology of alternative mating tactics.

Much of our work involves a strong field component with extensive international travel. Recent field research sites include Arizona, Costa Rica, Ecuador, Israel, Peru and Taiwan.

 

 

 

 

Teaching: Tropical Field Studies course in Ecuador

Postponed due to covid pandemic health concerns. Next offering being planned.

Previous course intinerary from 2019

Photos from the 2019 course

This unique field study course gives students hands-on experience in the ecology of tropical rain forests. Tropical Field Studies will explore the physical and biological factors that result in the formation of these forests, and their impressively high biodiversity. We will be based in a global biodiversity hot-spot in eastern Ecuador (Amazon basin), and at two higher-elevation cloud forest lodges in the Andes mountains. Students will explore some of the key animal and plant players in diverse ecosystems and their complex interactions. We will also consider the effect of human impacts on these forests, and how development processes affect local communities. Teaching methods will include faculty and guest lectures by local experts, immersive hands-on field teaching modules, and group field projects.
