The data provided here are the final datasets used in each of the primary models used in the manuscript "Artificial nightlight alters the predator-prey dynamics of an
apex carnivore". These data are the processed (as described in the manuscript) values derived from GPS-collared cougars, mule deer, and the cache site locations of cougar-killed mule deer. Additional summary data are available in tables and supplemental materials associated with this manuscript. GPS location data are owned by the Utah Division of Wildlife Resources, Nevada Department of Wildlife, and the National Park Service. In Utah, Nevada, and Arizona cougars and mule deer are legally classified as big game species. Due to the potential for abuse, location data are considered proprietary and protected under state law. As such, they are not publicly available in their raw format. Researchers interested in obtaining copies of these data can formally request access through a Government Records Access and Management Act (GRAMA) or similar mechanism submitted to the appropriate agency.
