Extended Data Figure 2: Seasonal variation in soil water content for 2007–2011.
From: Elevated CO2 further lengthens growing season under warming conditions
Values are means ± 1 s.e.m. for soil depth 5–25 cm (n = 5 plots). Mean annual soil water content (SWC) for control is represented by the horizontal grey line; vertical dashed lines show reproductive season timing for control.
