Abstract Details

2016, Master of Environmental Science, Miami University, Environmental Sciences.
A consensus species distribution model was created to predict the presence of the federally threatened plant Telephus spurge in three counties in the Florida panhandle. Final results were created by averaging results from a top generalized linear model created in this study with those of a top machine-learning model developed by a fellow researcher prior to this study. These two initial models began with the same data sets and followed the same procedure for spatial filtering, but then selected individual methodology relating to their specific model types and statistical concerns. Final predictions showed several areas of interest along the coast and around St. Andrew’s Bay, among others. The highest probability for Telephus spurge presence was located on Tyndall Air Force Base. Without researcher knowledge, Telephus spurge was actually discovered on Tyndall Air Force Base in one of these areas of high probability before this study was completed. This discovery is the first in that area and is distinct from previously known populations of Telephus spurge and represents a minor example of model validation through incidental ground-truthing. It is hoped that this study can continue to predict the location of new populations or preferred habitat to help in conservation efforts.
