Tropical Field Studies course in Ecuador

Winter break (December) 2020

**Revised winter break plan Course intinerary

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.

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). Much of our work involves a strong field component; recent tropical field research sites include Costa Rica, Ecuador, Israel and Taiwan. The lab uses a diverse array of social insects (army ants, paper wasps) and Neotropical birds as study organisms.
Ongoing projects include:

Neurobiology and behavior- comparative analyses of brain evolution in arthropods; social insect caste differences in brain development

Thermal physiology of social insects- species and population differences in temperature tolerances across landscapes; individual differences within social groups; group-level thermoregulation

Ecology & behavior of mixed-species foraging groups- species differences in bird attendance of army ant raids; social and ecological interactions among birds at shared resources

Population genetics of the army ant Eciton burchellii, examining gene flow and landscape effects

Thermal and sensory physiology in alternative-tactic mating systems (Meghan Barrett, Ph.D. research)

Nutritional physiology and chemical signalling in social insects (Katherine Fiocca, Ph.D. research)

Human- and mammal-safe insect control- testing effectiveness of the polyalcohol sweetener erythritol as an ingested insecticide in social and solitary insects

Mathematical models of communication and division of labor in organized biological systems
