Notes: df degrees of freedom, log.like = log likelihood, ΔAIC_c = deviation for AIC_c compared with top model, w _i = AIC_c weight
(Predictor variables included habitat type, month, sex, time of day, distance from water source, mean temperature, and total rainfall. Rows shown in bold indicate top models (ΔAIC_c < 2). Rainfall and temperature measurements were from the two hour period prior to positional fix, using data supplied by South African Weather Service (Pretoria, South Africa) for Beaufort West area, South Africa)
