Figure 5. Relationships between the absolute changes (A_e) in biocrust cover and those in organic C (a), aromatic compounds (b), and hexoses (c) during the first 46 months of the experiment at the Aranjuez experimental site, and between the relationship between the A_e in biocrust cover and the fungal: bacterial ratio at this site (d).

Solid lines are significant regressions fitted to the warmed plots. None of the regressions fitted to the non-warmed plots were significant.
