This summer my field assistant, Scott Morton, and I began experiments looking at how temperature mediates predator-prey and competitive interactions in aquatic insects. This work is part of the Doctoral Dissertation Improvement Grant proposal that we were awarded this year. We are collaborating with David Walters at the USGS in Fort Collins for this project. We are now in Ecuador, continuing our experiments in tropical aquatic insect communities. We hope this work sheds more light on elevation range limits of temperate and tropical aquatic insects! Stay tuned for results!
