In Distance: Distance Sampling Detection Function and Abundance Estimation

Duiker camera trap survey

Description

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
