... is poorly understood. We investigated flexibility in traits that affect thermal balance between black-capped chickadees ( Poecile atricapillus ) acclimated for 6 weeks to cold (−5°C) or control (23°C) environments ( n =7 per treatment). We made repeated measurements of basal and summit metabolic rates via...

...Emma S. Porter; A. Kurt Gamperl ABSTRACT We investigated how acclimation to 8, 4 and 1°C, and acute cooling from 8 to 1°C, affected the Atlantic salmon's aerobic and anaerobic metabolism, and cardiac function, during a critical swim speed ( U crit ) test. This study revealed several interesting...

..., acclimatory and evolutionary. Acutely, passive temperature effects often dictate an expected 2-fold increase in metabolic processes for every 10°C change in temperature ( Q 10 ). Yet, these acute responses often are mitigated through acclimation within an individual or evolutionary adaptation within...

NST is plastic, and capacity for heat production increases with cold acclimation. However, in lowland native rodents, hypoxia inhibits NST in BAT. We hypothesize...

In contrast, we observed acclimation-specific compensatory differences in respiration rates at both extremes...
