Track Plate Test Scenario
The links below take you to the scanned prints collected over a period of 2 weeks from a section of a trapping grid. Here we will examine only a 6 x 5 portion of the entire grid. Track plate stations are spaced 1 km apart and were checked for prints every 2 days. The section of the grid we are analyzing looks like this: x A2 A3 x x x B1 x B3 x x x x x x C4 C5 x x x D3 x D5 x x x x x x x Stations that produced fisher tracks are designated with their respective coordinates, with rows designated using letters and columns designated with numbers. Stations that failed to produce clear tracks are designated “x”. Position A1 (where no clear tracks were collected) is the northwest corner of the grid. The remainder of the grid is not shown above and you do not know what data may or may not have been collected at the stations not shown. The naming convention for the prints is illustrated by the following example: A1 06-12 LF1 Where: A1 is the grid coordinate 06-12 refers to June 12, the day the print was collected LF1 refers to the first example of a left front print collected from that station on that day (i.e., if there was a second left front print at the same station and day it would be A1 06-12 LF2, etc.) Your task is to tell how many individual animals are responsible for these prints: Station A2 [6-16 LF1, 6-16 RF1, 6-16 RF2, 6-18 LF1, 6-18 LF2, 6-18 RF1. 6-18 RF2] Station A3 [6-18 LF1, 6-18 LF2, 6-18 RF1, 6-23 LF1, 6-23 LF2, 6-26 LF1, 6-26 RF1] Station B1 [6-23 LF1, 6-23 LF2, 6-23 RF1, 6-23 RF2] Station B3 [6-20 LF1, 6-20 LF2, 6-20 LF3, 6-20 RF1, 6-23 LF1, 6-23 RF1, 6-23 RF2, 6-26 LF1, 6-29 LF1, 6-29 RF1, 6-29 RF2] Station C4 [6-23 LF1, 6-23 RF1, 6-29 LF1, 6-29 RF1] Station C5 [6-26 RF1] Station D3 [ 6-26 LF1, 6-26 RF1, 6-29 LF1, 6-29 RF1] Station D5 [6-26 LF1, 6-26 LF2, 6-26 LF3] Back to Main Test Page
