Figure 2.

Bimodal distributions of burrow‐to‐burrow movement distances by desert tortoises, based on weekly (5–8 day) radio‐tracking encounters in the Ivanpah Valley, California, U.S.A. Intermodal minima, representing thresholds separating movements within activity centers (below thresholds) from those among activity centers (above thresholds), are shown for (a) males, (b) females, and (c) subadults with dashed vertical lines and were estimate using kernel density estimation. See Appendix S1 for additional information.
