Dr. Pablo E. Gutièrrez-Fonseca is a faculty member in the Rubenstein School of Environment and Natural Resources at the University of Vermont. He is broadly interested in evaluating how freshwater ecosystems respond to and are transformed by climate change and human activities. Specifically, he studies the effects of hurricanes, droughts, and the El Niño–Southern Oscillation (ENSO) on aquatic communities (e.g., fish, shrimp, macroinvertebrates, algae), food webs, aquatic-terrestrial linkages, and leaf litter decomposition in urban and forested streams. He combines short-term experiments and long-term datasets to understand potential changes in the structure and function of stream ecosystems.  His study sites include a variety of stream types (e.g., lowland, montane, urban, perennial, and intermittent), mostly located in Costa Rica, Puerto Rico, and Vermont.
