Foliar Litter Decomposition: A Conceptual Model with Focus on Pine (Pinus) Litter—A Genus with Global Distribution

Figure 5

During decomposition, the concentration of AUR increases. The AUR concentration may be plotted versus accumulated litter mass loss. By doing that, we obtain a linear relationship, which is readily comparable for litter incubated in different climate zones and among different litter species. Scots pine (●), lodgepole pine (■), Norway spruce (▲). Data from [31, 52, 53], figure from [32].
