Table 2 Pearson correlation coefficients (mean and range) between tortuosity (measured using the straightness index), estimated speed, absolute turn-angle, and site fidelity (spatio-temporal clustering) averaged across the six cougars described in Table 1

From: Quantifying animal movement for caching foragers: the path identification index (PII) and cougars, Puma concolor
