The University of Toronto Department of Ecology and Evolutionary Biology supports several field courses a year. General information about our field courses can be found here and applications here. I am quite fortunate that I am able to do some of my yearly undergraduate teaching in field courses. I absolutely love this part of my teaching, and find it to be one of the most rewarding teaching experiences available at the University.
My interest in ecology and evolution was cemented by taking field courses as an undegraduate-- Marine Biology in the Virgin Islands through Bucknell University, and Field Behavioral Ecology and Mammalogy, through the SUNY Environmental Science and Forestry field station at Cranberry Lake, NY.
To date at the University of Toronto, I have taught 4 field courses. The first two, co-taught with Ivana Stehlik, were at Joker's Hill. Then, Aneil Agrawal Jonathan Shurin, and Itaught a joint UBC-Toronto course at Rancho Dioon, in Oaxaca state, Mexico (roughly 2-1/2 hours from Huatulco, Mexico). Some of us stayed here, at the Finca Monte Carlo, up the road from Rancho Dioon..
The msot recent field course I taught was with Megan Frederickson, at Wayqecha Cloud Forest on the slopes of the Andes and at Los Amigos in the Peruvian Amazon.
Photos from these field courses, taken by instructors and students, can be found at the following links.
