  • Description:
    "Based on our 2012 monitoring of several extant populations of A. cervicornis in the Caribbean (Huntington and Miller in prep), we hypothesized that A. cervicornis growth rates and tissue condition are enhanced when very dense spatial configurations (i.e. "thickets") of coral are achieved. Our research from 2013 focused on observational studies and an experimental bioassay to discern a mechanism to account for this greater coral condition, which we hypothesized was from the indirect enrichment of the coral from organic nutrients excreted form fish sheltering within the thicket. To test this hypothesis, we used an experimental bioassay study in two Caribbean locations: Dry Tortugas National Park (DRTO), Florida and St. Thomas, United States Virgin Islands (USVI) to determine if coral condition was enhanced when transplanted to a thicket site versus a low density A. cervicornis site. While DRTO contains both high density spatial configurations of A. cervicornis and high abundances of schooling reef fishes, schooling fishes are rarer in the A. cervicornis populations in St. Thomas. By performing the same bioassay experiment in each location we can isolate the influence of reef fishes to facilitate higher condition in A. cervicornis"--Page 2.
