Do slow-growing species and nutrient-stressed plants respond relatively strongly to elevated CO2?

Mainly based on a simulation model, Lloyd & Farquhar (1996; Functional Ecology, 10, 4–32) predict that inherently slow-growing species and nutrient-stressed plants show a relatively strong growth response to an increased atmospheric CO2 concentration. Compiling published experiments, I conclude that these predictions are not supported by the available data. On average, inherently fast-growing species are stimulated proportionately more in biomass than slow-growing species and plants grown at a high nutrient supply respond more strongly than nutrient-stressed plants.
