Short summary

We report a mechanistic model for linking biophysical and chemical processes in Cyanobacterial crusts comprised of trophically interacting photoautotrophs, aerobic and anaerobic heterotrophs, and nitrifiers. The biocrust model captures salient aspects of microbial activity and community organisation in response to diurnal cycles of light and temperature. The framework offers new mechanistic insights into a host of highly dynamic and spatially resolved processes shaping biogeochemical fluxes.
