| Summary: | Monitoring carnivores is critical for conservation, yet challenging because they are rare and elusive. Few methods exist for monitoring wide-ranging species over large spatial and sufficiently long temporal scales to detect trends. Remote cameras are an emerging technology for monitoring large carnivores around the world because of their low cost, non-invasive methodology, and their ability to capture pictures of species of concern that are difficult to monitor. For species without uniquely identifiable spots, stripes, or other markings, cameras collect detection/non-detection data that are well suited for monitoring trends in occupancy as its own independent useful metric of species distribution, as well as an index for abundance. As with any new monitoring method, prospective power analysis is essential to ensure meaningful trends can be detected. Here we test camera-based occupancy models as a method to monitor changes in occupancy of a threatened species, grizzly bears (Ursus arctos), at large landscape ... : All grizzly bear occupancy data- This dataset contains all detection-non-detection data for pictures from all grizzly bears. 1 indicates at least one picture; 0 indicates no pictures; NA indicates camera not running. - Each row contains data from one camera site - Each columns contains data from one 4-day sampling replicate - Names of column corresponds to the number of the first day of each 4-day windowSteenweg_GrizzlyAll.csvGrizzly bear family occupancy dataThis dataset is similar to all grizzly bear data, but only contains detection-non-detection data for pictures of grizzly bear family groupsSteenweg_GrizzlyFam.csvGrizzly bear occupancy Site CovariatesThis dataset contains site covariates present in the top occupancy models for both grizzly bear occupancy data setsSteenweg_SiteCovariates.csv ... |
