A biologist colleague of mine, Dr. David Lemmon, is offering summer field courses to both Pamana (May 21 - June 2, 2012) and the Brazilian Amazon (August 11 - 23, 2012). For the Amazon trip, you live on an Amazon River boat (shown at left) with excursions into the jungle.
The Amazon trip has been run a dozen times already and the Panama trip is new for this year. While I've never gone (there are few rocks in the jungle!), I have a number of students who've gone and they've all loved it and told me it was a tremendous learning experience.
There are no academic prerequisites but you have to be in good health, have a valid passport and immunizations, etc. You don't have to be a student, either, you can audit the course as an interested adult.
Here are a couple of posters with addtional information. Dr. Lemmon's contact information is on the posters, I'm sure he'd be happy to answer any questions about the courses.
