Summary of binomial GLMMs testing the effects of environmental variables on the probability of straw-coloured fruit bats to fly at their roosts during the day.

The response variable was assigned as 1 for the days when the bats flew in the roost and 0 otherwise. The first model included days when we trapped bats with mist nets in the roosts, therefore we included trapping day as a binary model predictor (trapping days vs regular days). Both models included individual ID and roost ID as random intercept factors. Marginal and conditional R2 were calculated with the function r.squaredGLMM of the MuMIn R-package [43]. Significant relationships are shown in bold and are plotted in Fig 2. Units of parameter range: Solar irradiance—MJ/m2; Precipitation—mm/day; Wind speed—m/s.
