The 4 best-fit models with variables (minimum ambient temperature = T_{a min} [°C], rainfall = rain [mm], absolute barometric pressure = bp [hPa], body mass = bm [g]) that explain differences in TDT use (min), mean daily body temperature (T_{b mean}, °C), and TDA duration (min)

The P-value is from a log likelihood ratio test performed for the 2 top models. The best-fit model for each variable is indicated in bold.
