Research overview: sample-size and fix-interval effects on home-range area

Home-range estimates depend not only on the animal but on how it was sampled, and this overview examines how the number of fixes and the interval between them shape the result. Too few locations underestimate range because rarely used areas go unsampled, while very frequent fixes inflate autocorrelation and, with naive estimators, paradoxically shrink the apparent range. Tracking duration matters too: a range estimated over one season may miss seasonal shifts or dispersal. The overview explains why comparing home ranges across studies with different sampling regimes is hazardous and why methods that account for the movement process are needed to reconcile them. Recognizing these design dependencies is essential to interpreting the wide variation in reported felid home-range sizes.
