Total diel displacement vs. NDVI. (a) Daily travel distance (km) vs. NDVI values for all individuals (grey points). Loess smoothers using linear regression show trends of the mean (solid line) and coefficient of variation (dashed line) as a function of NDVI. (b) Median daily travel distances for individuals during low (LFA), medium (MFA), and high (HFA) forage availability seasons. (c) Model predicted DD values by rank at the median values of the lagged DD covariate terms by social rank.
