Description

Cat removal and monitoring on San Nicolas Island

Usage

san_nic_rem

Format

A list consisting of 2 elements

rem

An M x J matrix of counts of individuals removed at each trap location for each primary period where M is the number of traps and J is the number of primary periods

y1

An N x J matrix of detections recorded over the same period as rem where N is the number of cameras and J is the number of primary periods

cells

A vector of length N giving the indices of each of the the removal traps where the additional monitoring was undertaken. Hence the additional monitoring data y1 was collected at rem[cells,]

nights

The number of secondary periods of sampling for each of the J primary periods

traps

a data.frame with M rows of trap locations

Details

A simulated example dataset of removal sampling and additional camera monitoring on San Nicolas Island, California. The data consist of the counts of cats removed at each of 100 leg-hold traps spaced randomly on the island over 20 separate removal (primary) periods. For each primary period, traps were set for 10 consecutive nights (secondary period).

The additional monitoring data consist of cat detections at cameras set at 30 of the leg-hold trap locations for a similar number of primary and secondary periods.
