Effect of temperature acclimation period on upper thermal tolerance in a terrestrial salamander

Several factors may explain the low variation in CT_max described in our study, including phylogenetic conservation of upper thermal limits, or a lack of sufficient temperature differences in our treatments to elicit a physiological response. Regardless, our results provide limited evidence that different acclimation periods affect the degree of phenotypic plasticity in CT_max in <i>Plethodon cinereus</i>.
