Extended Data Figure 5

Moving-window correlation between τ and vegetation stocks (a); and between τ and carbon in soils (b). In general, τ correlates negatively with vegetation (a), indicating shorter turnover times with a higher proportion of carbon in the vegetation. The majority of the patterns are consistent with the overall reduction of residence times in ecosystem carbon given allocation to vegetation pools (shorter lived by comparison with soil carbon pools). Conversely, the significance of soil carbon stocks in explaining the spatial variability of τ is pervasive (b). These results translate the trends in increasing τ with allocation of assimilated carbon to more persistent carbon pools.
