Thermal optima of\n                    <jats:italic>g<\/jats:italic>\n                    <jats:sub>m<\/jats:sub>\n                    shifted with growth temperature in both species, while\n                    <jats:italic>R<\/jats:italic>\n                    <jats:sub>l<\/jats:sub>\n                    remained consistently temperature sensitive with limited acclimation. The CO\n                    <jats:sub>2<\/jats:sub>\n                    response of\n                    <jats:italic>g<\/jats:italic>\n                    <jats:sub>m<\/jats:sub>\n                    were conserved across growth temperatures. These results show that the temperature sensitivity of\n                    <jats:italic>g<\/jats:italic>\n                    <jats:sub>m<\/jats:sub>\n                    is not fixed, but acclimates to growth temperature, with a stronger effect than species identity.
