Table 3. Average (±SE) chase tortuosity and speed performance during hound-assisted puma recaptures.

Average and maximum speeds (ms−1) are presented for both GPS and accelerometer-derived estimates. Sample sizes and measurement units are enclosed in parentheses, and results from Welch two-sample t-tests comparing hound and puma data are included.

Notes.

*

Denotes significant relationship (p ≤ 0.05). GPS speeds are inherently averaged over 6 s, whereas the accelerometer speeds are near instantaneous (see methods).
