Fig. 4. Bivariate correlations between the contrasts of microhabitat use and the contrasts of the slopes of stride frequency against speed (forced through the origin). (A) Relationship between the contrasts of time spent in the open microhabitat and the contrasts of the slopes of stride frequency against speed. (B) Correlation between the contrasts of time spent in the vegetated microhabitat and the contrasts of the slopes of stride frequency against speed. In both cases, including the contrasts of the slopes of stride length against speed gives the opposite result (r=0.76, P=0.017; r=-0.62, P=0.074, respectively).
