(A) Schematic of experimental timeline. (B) Weight of bats throughout the experiment. Standard diet bats were heavier on average, but between diet start and infection (day −21 and day 0) weight did not significantly vary. Post-infection (day 0 to day 20), standard and suboptimal-sugar diet bats gained a small amount of weight (linear mixed effects model output (lme), 0.06 g day^–1 estimate; df = 257, t = − 3.92, p = 0.001), while suboptimal-fat diet bats lost a small amount of weight (lme, −0.02 g day^–1; df = 257, t = −3.39, p = 0.008). Vertical dotted red line separates pre- versus post-infection days. (C) Pre-infection overall differences in estimated proportion of food consumed, based on average food provided minus weight of food leftover, corrected by average weight of bats in the cage. Suboptimal-sugar diet cages consumed more food than suboptimal-fat and standard cages (ANOVA, F = 4.32, df = 2, p = 0.02). (D) Post-infection overall food consumed, based on actual weight of food provided minus weight of food left over, corrected by average weight of bats in the cage. Suboptimal-diet cages consumed more food overall than standard diet bats, although suboptimal-sugar bats still consumed the most (ANOVA, F = 30.36, df = 2, p < 0.001). Boxplots show median, 25th and 75th percentiles and range or 1.5 × IQR. Asterisks indicate: *** p < 0.0005, ** p < 0.005, * p < 0.05, · p < 0.1.
