browse graphicPreview graphic
This dataset is a compilation of modeled spatial distributions of Threatened corals, Orbicella annularis (lobed star coral) and Orbicella faveolata (mountainous star coral)/Orbicella franksi (boulder star coral). in the shallow and upper mesophotic waters (0 – 60 meters depth) on the eastern Puerto Rico shelf (encompassing St. Thomas and St. John, U.S. Virgin Islands and the partial waters around Culebra and Vieques, Puerto Rico). Models for O. faveolata/O. franksi were combined into one model. All three Orbicella spp. area listed as Threatened under the U.S. Endangered Species Act. The raster datasets contain predicted probability of occurrence and prediction uncertainty for O. annularis and O. faveolata/O. franksi at four different model extents:
• 0 – 60 meter depth model: Orbicella spp. models encompassing the entire modeling region, both shallow and mesophotic depths from 0 to 60 meters (capped at 60 meters for Orbicella spp. known depth range in this region)
• 0 – 60 meter depth south shore only model: Orbicella spp. models of the south shore only removal of the mesophotic depths of the north shore, north of St. Thomas and St. John, USVI
• Shallow only model (0 – 30 meter depth): Orbicella spp. models of the shallow waters only, removal of the mesophotic depths
• Mesophotic only model (30 – 60 meter depth: Models of O. faveolata/O. franksi at mesophotic depths only remove of the shallow depths
Models were conducted using a presence/background sample model, which involves the use of presence-only data. Maximum entropy modeling was used specifically, initiated through the Java software program, MaxEnt.

Purpose Orbicellid corals (genus: Orbicella) are primary reef-building corals throughout the Caribbean in shallow and mesophotic coral ecosystems, and the three species in this genus are also listed as Threatened under the U.S. Endangered Species Act. There is a poor understanding of where they occur, which limits population monitoring and management. Orbicella spp. can also be used as a proxy for identifying mesophotic coral reef habitat (> 30 meter depth), as they are abundant in these ecosystems throughout the Caribbean. The probability of occurrence for Orbicella annularis and Orbicella faveolata/Orbicella franksi (combined) from shallow to mesophotic depths (0 – 60 meters) on the eastern Puerto Rico shelf was predicted using maximum entropy models, a presence/background sample modeling technique. The goals of our study were 1) to predict probability of occurrence for Orbicella spp. along the eastern Puerto Rico shelf and 2) to identify how abiotic environmental factors constrain that habitat based on varying model extents. The data in this accession were funded by the Virgin Islands Experimental Program to Stimulate Competitive Research under award NSF #0814417 to the University of the Virgin Islands; and the National Science Foundation Scholarship in Science, Technology, Engineering, and Mathematics under award NSF #1356632 to the University of the Virgin Islands.

Processing Steps
  • Parameter or Variable: Probability of Occurrence (calculated); Units: unitless; Observation Category: model output; Sampling Instrument: Models/Analyses > Data Analyses > Environmental Modeling; Sampling and Analyzing Method: Probability of occurrence for Orbicella annularis and Orbicella faveolata/Orbicella franksi were calculated by averaging ten maximum entropy modeling predictions using the Java version of MaxEnt. Using environmental predictors and presence-only data of Orbicella spp., MaxEnt creates a model and produces predicted distribution maps for the species being modeled. Each grid cell of the predicted distribution map demonstrates the probability of that species (in this case, Orbicella spp.) occurring within that grid cell. The normal output is habitat suitability, but prevalence of the species within the modeled region was used as a parameter in the model, converting the grids to probability of occurrence. These data are unitless. Habitat suitability maps have values ranging from 0 – 1, but probability of occurrence maps are displayed as a percentage of 0 – 100%. For more details, see Egan et al. (2021).; Data Quality Method: Model performance was assessed via discrimination capacity, which is the ability of the model to correctly distinguish between presences and background samples. This is represented by the area under the receiver operative characteristic curve (AUC). Performance was also assessed using reliability, of the agreement between predicted and observed values. Reliability is represented by mean absolute error (MAE). Model uncertainty was quantified to provide some indication of how sampling variability and model structure may have influenced the predicted distributions Uncertainty maps for each coral group’s model replicates were created by taking the standard error among the ten replicate cloglog spatial distribution maps, and were assessed visually for areas of high uncertainty. For more details, see Egan et al. (2021)..
