We used stable isotope analysis of nitrogen and carbon turtle epidermal samples to describe the trophic niche of the sampled sea turtle population by portraying δC as a habitat structure variable against δN as a resource gradient axis. We examined isotopic data for hawksbills (n = 64) and green turtles (n = 241) hand-captured across an 8-year time frame (2011-2019) to assess interspecific competition. We use statistical analysis to identify ontogenetic shifts associated with changes in trophic feeding to postulate changes to resource use. Our results indicate that stable environmental conditions around Buck Island Reef National Monument (BIRNM) allow for different trophic strategies across the two species with significantly...
This shapefile was made in 2009 after a second field anaysis of BUIS. Photo interpretation for these polygons were based on the 2007 Army Corp (imagery_armycorp file) imagery. This feature class is the end product for the BUIS vegetation product. To fully comprehend this feature class, please refer to the full "Buck Island Reef National Monument, U.S. Virgin Islands Vegetation Mapping Project, 2009" report:Moser, J. G., K. R. T. Whelan, R. B. Shamblin, A. J. Atkinson, J. M. Patterson. 2010. Buck Island Reef National Monument, U.S. Virgin Islands, Vegetation Mapping Project, 2009. Natural Resource Technical Report. NPS/SFCN/NRTR - 2010/293. National Park Service, Fort Collins, Colorado.
This dataset contains the capture histories for juvenile green (Chelonia mydas) and hawksbill (Eretmochelys imbricata) sea turtles tagged with an acoustic telemetry tag between 2012 and 2017. It contains information on how many days had passed since the tag was attached and whether or not the tag was still attached upon recapture. This dataset thus allows estimation of acoustic tag retention rates for these two species of sea turtle in our study site at Buck Island Reef National Monument (BIRNM), St. Croix, U.S. Virgin Islands (USVI).
