Study took place in Tai National Park Cote d'Ivoire in 2014. Filmed Maxwell's duikers (Philantomba maxwellii) were assigned to distance intervals; recorded distances are the midpoints of the intervals. This data includes only observations recorded at times of peak activity.

Format

A data.frame with 6277 rows and 6 variables

  • Region.Label strata names (single stratum)

  • Area size of study area (40.37 km^2)

  • multiplier spatial effort, as the proportion of a circle covered by the angle of view of the camera (42 degrees for these cameras)

  • Sample.Label camera station identifier (21 functioning cameras in this data set)

  • Effort temporal effort, i.e. the number of 2-second time-steps over which the camera operated

  • object unique object ID

  • distance radial distance (m) to interval midpoint
