AbstractThe fractal index by Katz and George (1985) for the characterization of planar curves is applied to wolf search paths recorded by radio-telemetry. All the sets of paths studied show spatial patterns whose com- plexity is between a straight line and a true random walk. Females’ fractal dimensions show significant changes throughout the year, depending on the state of their life cycle (normal, breeding and wandering). There are also differences between males and females, but not between adults and non-adults. The results are discussed with regard to wolf food-search strategies.
