USING NEON OBSERVATORY DATA TO ASSESS THE EFFECTS OF HURRICANE DISTURBANCE ON PUERTO RICO HEADWATER STREAM COMMUNITIES
The National Ecological Observatory Network (NEON) is a research platform designed to assess the impacts of ecological change on ecosystems in continental North America,Puerto Rico,and Alaska. NEON’s aquatic program is comprised of a suite of instrument and observational data collected at 34 sites, including two headwater streams in southwest Puerto Rico. Rio Cupeyes is a high-gradient, forested catchment and Rio Guilarte is in an agricultural catchment. Sampling began at both sites using standard NEON protocols in 2015, with fish sampling starting in February 2017. In September 2017, Hurricanes Irma and Maria made landfall in Puerto Rico, causing visible morphologic change to both NEON aquatic sites. Baseline species richness in Rio Cupeyes and Rio Guilarte is 4 fish species each and 114 and 117 macroinvertebrate taxa, respectively. Standardized sampling was conducted post- hurricane, suggesting a significant decrease in fish abundance. We anticipate a similar trend in the post-hurricane macroinvertebrate community. Using NEON abiotic data such as stream discharge, water chemistry, and stream morphology, we are able to analyze trends in macroinvertebrate and fish community metrics data pre- and post-disturbance.
