Responses of Ecosystem CO₂ Fluxes to Short-Term Experimental Warming and Nitrogen Enrichment in an Alpine Meadow, Northern Tibet Plateau

Figure 2

Diurnal variations of soil respiration under different treatments in alpine meadow measured on July 22~23 (a) and August 21~22 (b), 2012. CK, control (solid square with dot line); N, N addition (open triangle with dot line); W, warming (solid square with straight line); W + N, warming plus N addition (open triangle with straight line). Values represent the mean ± SE (𝑛=4).
