Author: Edwin A. Hernandez, Ph.D. Institution: University of Puerto Rico Rio Piedras – Biology Department Year: 2006 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,…
Author: David L. Ballantine, Ph.D. Institution: University of Puerto Rico Mayaguez Year: 2006 One of the recently recognized threats to coral reef health is overgrowth by macroscopic algae. Algal blooms are becoming increasingly widespread on a worldwide scale with the phenomenon involving both geographical expansion and increased biomass. Virtually all macroalgal blooms appear to be initiated by nutrient…
Author: Edgardo Ojeda, Ph.D. Institution: University of Puerto Rico Mayaguez Year: 2007 Known spawning aggregation sites (SPAG’s) for reef fishes from Puerto Rico consisted only of several red hind (Epinephelus guttatus) sites and one each for tiger grouper (Mycteroperca tigris) and mutton snapper (Lutjanus analis). This project initiated an interview-based survey as a first step to identify additional…
Author: David Mann, Ph.D. Institution: University of South Florida Year: 2008 Field trips to Mona Island and the West Coast of Puerto Rico and subsequent data analysis have revealed a unique sound associated with male red hind (Epinephelus guttatus) territoriality, which has been identified and characterized. Data corresponds to two months of recordings from long-term acoustic recorders (LARS)…
