Figure 4
Estimated proportion of explained variance (adj. R2: solid line) and intercept (dashed line) as a function of minimum ground speed ( v g ) starting at 0.5m/ s stopping at 10m/ s . Ground speed was modeled using generalized linear mixed models predicted by instantaneous direction (d i ) and speed (v i ) with individual as random effect and including a temporal autoregressive function to account for spatio-temporal autocorrelation.
