Kernel density estimators are often used for measuring home ranges and this is useful for measuring interactions between animals and their environment. However, kernels are sensitive to the choice of a smoothing factor (h).
For reptiles, Row & Blouin-Demers (2006) recommended using an h that creates a 95% contour area equal to the 100% minimum convex polygon. I have written two functions in R to do this for any tracking data set.
