Figure?4. Summary of correlations among changes in soil water, abundance of dominant plant taxa and plant community biomass increases with CO2 enrichment in mesic grassland, semi-arid grassland and xeric shrubland. Solid arrows denote positive correlations among ... Xeric shrubland The xeric shrubland responses to CO2 enrichment were a dramatic departure from those of the mesic and semi-arid grasslands. Carbon dioxide enrichment at the NDFF had no effect on soil water content (Nowak et al. 2004a) or on cumulative total aboveground and belowground biomass (Newingham et al. 2013) and productivity of dominant annual plant taxa (Smith et al. 2014; Fig.?4) following 10 years of CO2 enrichment. Thus, there was no basis for testing correlations among �� values for soil water content, dominant taxa and aboveground biomass in this system. Soils gradient The total community biomass increase resulting from CO2 enrichment varied considerably among soil Quinapyramine types in Selleckchem Neratinib the LYCOG experiment. Mean community biomass �� was 1.0 on the fine-textured clay soil and 1.4 on the silty clay and sandy loam soils (Fig.?5A), corresponding to 23�C35 % increases in aboveground biomass with CO2 enrichment. Soil water content mean �� was 0.1�C0.2 (range 0.03�C0.31) in the clay and silty clay soils, increasing to 0.85 (range 0.50�C1.04) on the sandy loam soil (Fig.?5A), which also had the highest mean soil water potential (Fig.?5A, inset). S3I-201 order These values of �� corresponded to 1�C26 % increases in soil water content with CO2 enrichment. Community biomass �� was not correlated with soil water content �� on any soil individually (0.06
