Figure 6: A scatterplot and regression of the average number of days after June 1 that plots attained active spring physiological response (NEE > 2.0 μmol m-2 s-1) as a function of the average date after which soils became moist ( > 0.13 SWC v/v).
From: Complex responses of spring vegetation growth to climate in a moisture-limited alpine meadow

Symbols represent different experimental plot treatments across the three years of the experiment. Each point represents the average of four replicate plots.
