Dr. Hernandez is currently an Affiliate Researcher and Lecturer at the Department of Biology University of Puerto Rico in Río Piedras (UPR). Obtained his B.Sc. in Marine Biology at the  UPR-Humacao, his M.Sc. in Environmental Microbiology at the UPR-Río Piedras, and his Ph.D. in Tropical Biology, with a specialization in Coral Reef Ecology at UPR-Río Piedras. He also completed post-doctoral training in Coral Molecular Microbiology at UPR-Río Piedras. He has taught courses in Ecology, Ecology of Puerto Rico, Marine Biology, and Coral Reef Conservation and Management Biology. He also founded the Coral Reef Research Group at UPR (1996), and was co-founder of the Culebra Island’s Community-Based Coral Aquaculture and Reef Rehabilitation Project (2003). He has also been a member of the Caribbean Fishery Management Council’s Habitat Advisory Panel since 2000. His main research areas include: 1) Ecology of coral reef benthic and fish communities; 2) Anthropogenic impacts in coral reefs; 3) Climate change impacts in coral reefs; 4) Impacts of coral diseases; 5) Functioning and design of marine reserves; 6) Coral aquaculture; and 7) Coral reef restoration.

Current Project:
Selective Monitoring of Puerto Rican Coral Reefs

Edwin A. Hernández-Delgado, Univ. of Puerto Rico - Río Piedras, Dept. of Biology

This project is aimed at obtaining the spatial and temporal synoptic understanding of coral reef health and the factors affecting it through repeated assessments at a subset of previously characterized permanent transects using standardized techniques. In contrast to previous assessments, however, this study has used more intensive in-situ sampling and was conducted at three different depth zones. The objectives of this project are to (1) provide a continued temporal baseline (over a variety of reef locations and conditions) that can be used to evaluate the effect (trend) of climate change, localized anthropogenic factors, and/or management practices on the health of coral reef benthic and fish communities, (2) provide a baseline for understanding the rate of temporal change and variability in coral reef benthic and fish communities under variable conditions, and (3) infer possible causative factors underlying observed changes. This design will allow test null hypotheses that there are no significant differences in spatial and temporal patterns in benthic and fish community structure among reefs (within each individual geographic region), and among geographic regions.
