Code to evaluate occupancy and surface availability of Siskiyou Mountains salamanders (Plethodon stormi) and Scott Bar salamanders (P. asupak) in northern California, 2023-2024

The code in this repository generates and analyzes directed acyclic graphs (DAGs) representing hypotheses about variables affecting the occurrence and surface availability of Plethodon salamanders in northern California; formats data from field surveys and GIS for analysis; and analyzes multi-scale occupancy models, including model selection, to evaluate the model and variables with the best predictive performance for evaluating occurrence and surface availability of the salamanders.
