Identifying individual pumas from tracks
1999 (unknown)
In a previous study using discriminant analysis, it appeared possible to distinguish among individual pumas (puma concolor) by using several measurements taken from their tracks. However, the analysis was done using a small data set. We have now enlarged the sample, identified sources of variation inherent in the procedure, and identified the strongest variables. Our procedures, done in the laboratory using simulated tracks, used measurements taken by hand from acetate tracings and obtained from computerized image processing. The study continues, but we are confident now that we can distinguish 90% or more of individuals based on track tracings. This technique can be used in radio-tracking studies to determine whether tracks found are from pumas without collars, and in track surveys to help identify individuals. It also may have utility in identifying an offending animal, especially where dogs cannot be used.
