Muted responses to heat in a nocturnal tropical rodent

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 33degree celsius, but no increases in metabolic rate were observed as high as 38.2degree celsius, indicating tropical rodents may be resilient as climate change progresses.Abstract in Malay is available with online material.
