Location Analysis

This panel provides a number of analyses of location data, which are used either to provide simple inter-location measures, including dispersal detection, or to estimate home ranges. A wide variety of different methods of range analysis have been published. Ranges implements those that have been used to produce refereed publications beyond a first description, including convex polygons (sometimes called minimum area convex polygons, MCPs or MAPs), #Concave Polygons,concave polygons (with restricted edges), polygons in #Clusters,clusters, #Ellipses, ellipses and contouring from #Harmonic Means,harmonic means and other density #Kernels,kernels. Grid cells may be plotted by selecting options within #Concave Polygons,concave polygons.

The pros and cons of these different techniques are discussed in more detail in the Review Of Home Range Analyses, review of home range analyses and for a more comprehensive recent review, see “A Manual for Wildlife Radio Tagging” (Kenward 2001) and Kenward et al. 2001.

Below you will find a brief outline of each technique and a link to a description of how it is implemented in Ranges.
