Evergreen species are widespread across the globe, representing two major plant functional
forms in terrestrial models. We reviewed and analysed the responses of photosynthesis and …

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 …

Most plants show considerable capacity to adjust their photosynthetic characteristics to their
growth temperatures (temperature acclimation). The most typical case is a shift in the …

The number and intensity of heat waves has increased, and this trend is likely to continue
throughout the 21st century. Often, heat waves are accompanied by drought conditions. It is …

The response of tree growth to a change in temperature may differ in predictable ways.
Trees with conservative growth strategies may have little ability to respond to a changing …

The frequency and intensity of heat stress events globally have increased over the past 20
years. Climatic modeling predicts that this trend will continue throughout the 21st century …

While interest in photosynthetic thermal acclimation has been stimulated by climate
warming, comparing results across studies requires consistent terminology. We identify five …

Leaf thermoregulation has been documented in a handful of studies, but the generality and
origins of this pattern are unclear. We suggest that leaf thermoregulation is widespread in …

Rising atmospheric carbon dioxide (CO2) concentrations may warm northern latitudes up to
8° C by the end of the century. Boreal forests play a large role in the global carbon cycle …
