PMRI, along with our partners at the University of Guam Marine Lab, the Palau International Coral Reef Center, the Yap Environmental Protection Agency, and the Kaday Community and Cultural Development Organization, is happy to announce a recent publication entitled, “Watershed discharge patterns, secondary consumer abundances, and seagrass habitat condition in Yap, Micronesia“, by Peter Houk, Yimnang Golbuu, Berna Gorong, Thomas Gorong, and Christina Fillmed.
In this publication, watershed discharge, water quality, and seagrass assemblages were examined along the western coast of Yap Proper, Micronesia. In short, this study found that submarine groundwater discharge was a more continuous source of freshwater input into seagrass habitats than stormwater discharge, and that groundwater discharge was associated with the presence of macroalgae and reduced seagrass health. Additionally, sea cucumber densities in areas with submarine groundwater discharge were found to be lower than at comparable locations. Low cucumber abundances were also associated with poor seagrass condition. Future research is needed to attempt to attribute cause to individual local stressors.
