Data for ‘Climate warming alters photosynthetic responses to elevated [CO2] in prairie plants’
The impact of elevated [CO2] and climate warming on plant productivity in dryland ecosystems is influenced strongly by soil moisture availability. We predicted that the influence of warming on the stimulation of photosynthesis by elevated [CO2] in prairie plants would operate primarily through direct and indirect effects on soil water. We measured light-saturated photosynthesis (Anet), stomatal conductance (gs), maximum Rubisco carboxylation rate (Vcmax), maximum electron transport capacity (Jmax) and related parameters in four C3 plant species in the Prairie Heating and CO2 Enrichment (PHACE) ...
