摘要: To predict how forests will respond to rising temperatures and atmospheric CO2 concentrations, we need understand trees both of these environmental factors. In this review, discuss the importance scaling, moving from leaf-level responses those canopy, short-term long-term vegetation climate change. While our knowledge leaf-level, instantaneous photosynthesis, respiration, stomatal conductance, transpiration water-use efficiency elevated temperature is quite good, ability scale up larger spatial temporal scales less developed. We highlight which physiological processes are least understood at various levels study, ignoring differences in or a process impedes forest carbon water fluxes be altered future. also synthesize data literature show that light respiration follows generalized response across studies, compensation point photosynthesis reduced by growth CO2. Lastly, emphasize move beyond single factorial experiments whenever possible, combine treatments studies tree performance.
