Multi-Year Lags between Forest Browning and Soil Respiration at High Northern Latitudes

Figure 4

Observed versus predicted soil respiration (g C m−2 yr−1) for the best-performing linear model summarized in Table 1.

Solid line shows 1∶1, dashed line (with grey error region) the relationship between observed and predicted values. Point size indicates number of years reported by each study (cf. Figure 2), and was used as a weighting factor in all analyses.
