In this paper the
researchers introduce a new technique for delineating animal home ranges : the potential path area (PPA) home range.
The technique is simple and intuitive
PPA home ranges are based
on existing theory from time geography. An animal's movement is constrained by
known locations in space–time (i.e., n telemetry
points) and a measure of mobility (e.g., maximum velocity).
Using the formulation the
researchers provide, PPA home ranges can be easily implemented in a Geographic
Information System (GIS).
The researchers say the
advantage of the PPA home range is the explicit consideration of temporal
limitations on animal movement. They identify the PPA home range as a
stand-alone measure of animal home range or as a way to augment existing home
range techniques.
Future developments are
highlighted against the backdrop of the usefulness of time geography for
wildlife movement analysis. To facilitate the adoption of this technique the
researchers provide a tool for implementing the new method.
So guys go ahead and give
it a try.
