Northern Diamondback Terrapin Probability of Occurrence (POC) Model for MA, RI, CT, NY, NJ, DE, MD, and VA. Warmer colors represent greater values and therefore, a higher probability of terrapins occurring in that area. The POC was developed by Karen Leu and Brooke Maslo (Rutgers University) and is based on documented occurrence between the years 2000-2012 as well as several environmental variables (see full report by S. Egger, 2016). The POC figure is the raw Maxent output. It contains the predicted probability of occurrence on a 0 - 1 scale, with 0.7722 being the highest possible value. Thresholds of 0.5, 0.6, and 0.3188 are shown. The latter value is the 10th percentile training presence logistic threshold, which...
