The goals of this course are two-fold. First, participants will receive advanced training in insect diversity, form, and function, as well as field techniques that facilitate entomological research and conservation in the tropics, covering groups ranging from butterflies to beetles, bees, and aquatic insects, among others. Second, students will be introduced to an astonishing array of terrestrial and aquatic habitats that shelter a greater diversity of plant and animal species than anywhere else on the planet. Above all, participants learn by doing: we will spend most of our time studying actual insects in the field, from the tops of towering tropical trees to the bottom of oxbow lakes. Our field activities will be supplemented by selected readings from the primary literature covering topics on theoretical and applied tropical biology and entomology, as well as conservation in the Andes and Amazon regions. Participants will also gain exposure to cutting-edge research in other tropical biology fields at one of the most active biological research stations in the Neotropics.
