Abstract: We hereby developed a Markov random field based spatial-explicit community occupancy model that accounts for spatial auto-correlation and interspecific interactions in occupancy simultaneously while also account for interspecific interaction in detection. Simulation results showed the new model can distinguish different mechanisms. We applied this new model to camera trap data of Fisher(Pekania pennanti)-Marten(Martes americana) and Coyote(Canis latrans)-Fox(Vulpes vulpes) system in Apostle Island National Lakeshore. Results showed the observed partition pattern between marten and fisher may be better explained by a flipped mainland-island source-sink pattern rather than competition, while we detected some evidence that on top of the mainland-island source-sink pattern, there was a positive association between fox and coyote than deserve further study.
