Thermal acclimatisation to heatwave conditions is rapid but sex-specific in wild zebra finches
Scientific Reports, 2023 Under climate change, increasing air temperature average and variability pose substantial thermal challenges to animals. While plasticity in thermoregulatory traits could potentially attenuate this impact, whether thermal acclimatisation can occur ...
