Et Zucc. Seedlings", "description": "AbstractKey messageIn the open-field warming experiment using infrared heaters, 3\u00a0\u00b0C warming affected soil respiration more in the deciduousQuercus variabilisBlume plot than in the evergreenPinus densifloraSieb. et Zucc. plot, but did not affect the plant biomass in either species.ContextUnderstanding the species-specific responses of belowground carbon processes to warming is essential for the accurate prediction of forest carbon cycles in ecosystems affected by future climate change.AimsThis study aimed to investigate the effect of experimental warming on soil CO2 efflux, soil-air CO2 concentration, and plant biomass for two taxonomically different temperate tree species.MethodsExperimental warming was conducted in an open-field planted with Q. variabilis and P. densiflora seedlings. Infrared heaters increased the air temperature by 3\u00a0\u00b0C in the warmed plots compared with the air temperature in the control plots over a 2-year period.ResultsThe increase in air and soil temperature stimulated soil CO2 efflux by 29 and 22\u00a0% for the Q. variabilis and P. densiflora plots, respectively. Seasonal variation in the warming effect on soil CO2 efflux was species-specific. Soil CO2 efflux was also positively related to both soil temperature and soil water content. The soil moisture deficit decreased the difference in soil CO2 efflux between the control and warmed plots. Warming did not affect soil CO2 concentration and plant biomass in either species; however, the mean soil CO2 concentration was positively correlated with root and total biomass.ConclusionWarming increased soil CO2 efflux in both Q. variabilis and P. densiflora plots, while the increase showed remarkable seasonal variations and different magnitudes for the two species.", "keywords": ["0106 biological sciences", "soil temperature", "evergreen tree", "soil water", "Red pine", "seedling", "soil respiration", "01 natural sciences", "experimental study", "Pinus resinosa", "Climate change", "Pinus densiflora", "seasonal variation", "concentration (composition)", "Quercus variabilis", "Oriental oak", "carbon dioxide", "Soil respiration", "04 agricultural and veterinary sciences", "15.

Associated with month\uffe2\uff80\uff90to\uffe2\uff80\uff90month changes in temperature were concomitant changes in R in the light (Rlight) and darkness (Rdark), with both processes being more temperature dependent in well\uffe2\uff80\uff90watered trees than under drought. Overall rates of Rlight and Rdark were not significantly affected by [CO2]. By contrast, overall rates of Rdark (averaged across both [CO2]) were ca. 25% lower under drought than in well\uffe2\uff80\uff90watered trees. During summer, the degree of light inhibition of leaf R was greater in droughted (ca. 80% inhibition) than well\uffe2\uff80\uff90watered trees (ca. 50% inhibition). Notwithstanding these treatment differences, an overall positive relationship was observed between Rlight and Rdark when data from all months/treatments were combined (R2\uffe2\uff80\uff83=\uffe2\uff80\uff830.8). Variations in Rlight were also positively correlated with rates of Rubisco activity and nitrogen concentration. Light inhibition resulted in a marked decrease in the proportion of light\uffe2\uff80\uff90saturated photosynthesis respired (i.e. reduced R/Asat). Collectively, these results highlight the need to account for light inhibition when assessing impacts of global change drivers on the carbon economy of tree canopies.</p>", "keywords": ["0301 basic medicine", "0106 biological sciences", "Light", "01 natural sciences", "nitrogen", "ribulosebisphosphate carboxylase", "Trees", "Keywords: carbon", "leaf respiration", "Photosynthesis", "Eucalyptus", "concentration (composition)", "droughts", "drought stress", "Photorespiration", "Temperature", "Rlight", "Darkness", "Photochemical Processes", "6.
