资源简介:
Data to support analysis of the relationship between human influences and the likelihood of a wolf kill occurring in a given location. Kill site (i.e., used) locations were identified in the field using the cluster searching method. Matched non-kill (i.e., available) locations were drawn from a 10km radius centered around the wolf GPS collar location immediately preceding the kill (i.e., the last location prior to the formation of the cluster). Continuous covariates were standardized prior to inclusion in models; here we provide the raw values prior to standardization. Column names refer to the following: siteID (identifier for each kill site [i.e., used] location and its matched non-kill [i.e., available] locations) used (binary indicator of whether the location represents a kill site [1] or non-kill site [0]) datetimeLocal (date and time associated with kill site formation, in Mountain Standard Time) x_nad83z12 and y_nad83z12 (X and Y UTM coordinates of location, respectively. In NAD 1983 Zone 12N [EPSG 3742]) day (binary; whether the kill occurred during daylight hours, determined using the suncalc package in program R) can (percent canopy cover of the location, from the National Landcover Database) prey (relative prey availability index, from a utilization distribution calculated based on spatially-explicit yearly aerial elk counts) tpi (terrain position index, calculated from USGS digital elevation model using the raster package in program R) northness (cosine of aspect, calculated from USGS digital elevation model using the raster package in program R) snowCm (snow depth in centimeters, based on local SNOTEL and National Weather Station records) distMoto (Euclidean distance to the closest paved plowed road, based on road data from local cities and counties with additional manual digitization where appropriate) distNonmoto (Euclidean distance to the closest unpaved oversnow travel route, based on US Forest Service shapefiles and additional manual digitization based on ground-truthing) distFeed (distance to the nearest active ungulate feed ground) hunt (binary indicator of whether the wolf had [1] or had not [0] been exposed to hunting by humans)
