Fig. 4. A graph showing the output from the mixed model statistics of mean take-off
and landing forces at each horizontal range. The error bars represent the 95%
confidence intervals. By ignoring the few jumps at 2 m, when the squirrel
consistently landed at the more rigid base of the pole, the square of the
Pearson product moment correlation coefficient (the r2
value) improves from 0.61 to 0.99.
