Fig. 2

The proportion of maximum seasonal root (standing crop) and shoot (NDVI; leaf cover) growth for mixed-vegetation plots in 2013 and 2014, separated by warming and exclosure treatments. a Proportion maximum shoot and root growth in 2013 and 2014, separated by exclosure treatment with warming treatments combined. Black dashed lines with closed circles indicate root standing crop with no herbivory, gray dashed lines with open circles are root standing crop with herbivory, gray solid lines with open squares are NDVI with herbivory, and black solid lines with closed squares are NDVI without herbivory. The timing of leaf cover was significantly different between plots with and without herbivory, but the timing of root standing crop was not. b Proportion maximum shoot and root growth in 2013 and 2014, separated by warming treatment with exclosure treatments combined. Black dashed lines with closed circles indicate ambient root standing crop, gray dashed lines with open circles are warmed root standing crop, gray solid lines with open squares are warmed NDVI, and black solid lines with closed squares are ambient NDVI. The timing of leaf cover was significantly different between warmed and unwarmed plots, but the timing of root standing crop was not. Sample size (N) was 12 for each of the two treatments (Error bars indicate ±1 SE)
