  1. Covariates were scaled (mean = 0, standard error = 1)
  2. GLMM framework: Movement ~ Reservoir volume:Sex + Daily rainfall:Sex + Sex*Season. Male sex and wet season were used as reference categories to present modeling results
  3. ID, individual identification; N obs., number of observations; N gr., Number of groups for random effects; Var., variance; SD, standard deviation; β, parameter estimate; SE, standard error; z, z-statistic value; p, statistical significance level; CI, confidence interval
  4. *p value statistically significant (< 0.05)
