Mean 24 h patterns of core body temperature in six free-living mammal species exposed to austral summer heat (mean maximum black globe temperature above 40 °C) in their natural habitat. All animals had free access to water. SD shows variability between individuals. Data from: elephant (Loxodonta africana), n = 5, [81]; blue wildebeest (Connochaetes taurinus), n = 5, Boyers et al., unpublished; lion (Panthera leo), n = 5, Trethowan et al., unpublished; blesbok (Damaliscus pygargus phillipsi), n = 3, Laburn et al., unpublished; cheetah (Acinonyx jubatus), n = 4, Hetem et al., unpublished; springbok (Antidorcas marsupialis), n = 5, [61]
