Testing for Habitat Detection Distances Using Orientation Data

Zollner and Lima (1997) have attempted to fill the gap in our knowledge about the ability of real organisms to detect habitat at a distance. In a recent paper, they have introduced a novel approach that they believe will demonstrate how to detect perceptual thresholds in small mammals. They suggest that the movement of white-footed mice (Peromyscus leucopus) is influenced by their limited ability to visually recognize "preferred" habitat (woods) from relatively long distances (> 10 m). However, there is a possible flaw in their design and analysis that we feel others should be made aware of before emulating Zollner and Lima's study.
