Short summary
Besides performing multiple ecosystem services individually and collectively, biocrust constituents may also create biological networks connecting spatially and temporally distinct processes. We found evidence of fungal loops within biocrusts but only in cyanobacteria-dominated crusts for the inorganic N form NH4+. Combined with our sequencing effort, our findings suggest that even localized, minor rainfall events may allow dark septate Pleosporales to rapidly translocate N within biocrusts.
