# Small increases in ambient temperature reduce offspring body mass in an equatorial mammal [https://doi.org/10.5061/dryad.3bk3j9krw](https://doi.org/10.5061/dryad.3bk3j9krw) Our study used life history, body mass, genetic, and environmental data collected between August 2000 and March 2018 from a population of wild banded mongooses in Queen Elizabeth National Park, Uganda. ## Description of the data and file structure The dataset includes body mass of 215 banded mongoose pups ('Individual\_identity') aged 28-38 days ('weight' in grams), along with their date of birth, sex, age at weighing (in days), the identity of their social group ('group') and mother ('mothers\_ID'), the number of lactating females in their group ('number\_lactating\_females), the mean daily maximum temperature over the 30 days after birth ('temp' in degrees C), and mean daily rainfall over the 30 days prior to birth ('rain' in mm). There is no missing data. ## Sharing/Access information NA ## Code/Software NA
