摘要

Background and Aims Fluctuations in [CO2] have been widely studied as a potential driver of plant evolution; however, the role of a fluctuating [O-2]:[CO2] ratio is often overlooked. The present study aimed to investigate the inherent physiological plasticity of early diverging, extant species following acclimation to an atmosphere similar to that across the Triassic-Jurassic mass extinction interval (TJB, approx. 200 Mya), a time of major ecological change.
