| Abstract: | We measured the thermoregulatory characteristics of a common, tropical murid rodent, Sundamys muelleri. Subcutaneous body temperatures and evaporative water loss increased at ambient temperatures above 33°C, but no increases in metabolic rate were observed as high as 38.2°C, indicating tropical rodents may be resilient as climate change progresses. Abstract in Malay is available with online material. |
