Acclimation and adaptation components of the temperature dependence of plant photosynthesis at the global scale
Summary The temperature response of photosynthesis is one of the key factors determining predicted responses to warming in global vegetation models ( GVM s). The response may vary geographically, owing to genetic adaptation to climate, and temporally, as a result of acclimation to changes in ambient...
