title: Data from: Chronic traffic noise increases food intake and alters gene expression associated with metabolism and disease in bats

description: Anthropogenic noise exposure has deleterious effects on the foraging
 ecology of many animals. However, the effects of chronic anthropogenic
 noise on food intake and health condition in wildlife remain largely
 unknown. We tested whether traffic noise exposure over multiple days would
 change food intake and would have effects on the health of Asian
 particoloured bats. We broadcast traffic noise to the bats of two
 noise-exposure groups (group A, 5 bats; group C, 6 bats) and broadcast
 silence files to the bats of two control groups (group B, 5 bats; group D,
 6 bats) for 12 days. We measured the changes in food intake, body weight,
 and concentration of faecal triiodothyronine (T3) and thyroxine (T4) in
 groups A and B. We compared the transcriptional profiles in brain, kidney
 and liver tissues between bats in groups C and D. The bats exposed to
 traffic noise had a significantly higher daily food intake and a
 significantly greater body weight than bats in control group during the
 period of playback. Faecal T3 and T4 were higher in the noise-exposure
 group after playback had been on for more than one day. We found a total
 of 169 differentially expressed genes (DEGs) between noise-exposure and
 control groups. Some DEGs related to stress response were up-regulated in
 the bats exposed to noise. The 169 DEGs were mainly enriched in Gene
 Ontology (GO) terms associated with metabolism, fundamental cellular
 processes, stress response and immune response. The Kyoto Encyclopedia of
 Genes and Genomes (KEGG) pathways affected by noise exposure were linked
 with metabolism, disease, apoptosis, autophagy, phagosome and ribosome.
 Synthesis and applications. Our results suggest that bats exposed to
 chronic traffic noise while roosting may need more energetic intake and
 have a greater motivation to forage than others not exposed to noise,
 probably as a result of a stress response. Furthermore, chronic traffic
 noise may increase the risk of metabolic dysregulation, immune disorders,
 and other diseases. Management measures for reducing noise disturbance,
 for example, implementing sound barriers, are essential.
