Research interests include:

Jorge R. Ortiz-Zayas is a limnologist with research interest in hydrology, water management and nutrient (C, N) cycling. Projects directed by Ortiz focus on the study of how humans alter the cycling of water and nutrients in tropical watersheds. His research also aims at promoting the restoration and the integrated management of water resources and aquatic ecosystems.  In Puerto Rico, streams and their watersheds are heavily altered by urbanization, dams, and channelization and their biota are being impacted by pollution and overfishing .  Thus, there is an urgent need to understand the functioning of tropical stream ecosystems, how they are being impacted, to aid in their sustainable management.  His laboratory contributes to aquatic habitat restoration initiatives across the Island through hydrologic, physical habitat assessments, and water chemistry characterizations of inland waters.
