Sampling comments: "Rodent populations were followed from May 1971 through January 1974... data were collected... by live-trapping on a 10 x 10 grid (1 ha) with 10-m trap spacing. Sherman live traps baited with cracked milo were run on four consecutive nights at roughly bimonthly intervals. Two traps were placed at alternate stations, and double-trap stations were changed each trap night"
sampling effort presumably 100 traps x 4 nights x 4 sampling periods (May, July, September, November)
