"StudyAreas.csv" lists the study area-specific files with trap locations ("traps_...csv") and bear encounter histories ("caps_...txt") and summarizes data collection results.Also provided in this file are the year of sampling, the forest region sampled (boreal or Great Lakes St. Lawrence ["GLSL"; Rowe 1972]), and the Wildlife Landscape Zone (WLZ) i.e. management zone sampled. "traps...csv" files provide numeric labels (detectorID) and x- and y-coordinates of barbed wire hair corrals on each study area. Coordinate units are UTMs (datum = NAD83; longitude zone included in the filename at end after "Z")Wherever temporal sampling effort varied among sampling occasions, week-specific sampling effort in days is provided as additional columns in traps files. These additional colums are usually recognized by the 'secr' R package and included as 'usage' information when traps and capthist objects are created. "caps....txt" files are individual-specific encounter histories. Columns are (1) "session", which references the study area (and year for study areas sampled in multiple years), (2) "indiv": an individual identifier for different bears, (3) "ocn" is the temporal sampling occasion, (4) "trap": is an identifier for a sampling location (coordinates in corresponding "traps...csv" file), and "sex" ("fem" or "mal").Encounter histories exclude repeat detections of the same individual at the same trap within occasions All "caps" and "traps" files include the study area name and the year of sampling in the file name to ensure encounter histories can be matched to the appropriate traps. Session names are unique across study area and year-specific data sets. Session names are study area names except for study areas sampled in more than one year. For those study areas, we appended the year of sampling to the study area name for all years other than the first year.E.g. for the study area named "Sowden", the session name for 2017 data is "Sowden", and for data from subsequent years the session names are "Sowden2018", and "Sowden2019". Example R script for importing study-area specific data and formatting them as a capthist object is provided ("RScript_InputBlackbearSECRdata.txt").
