Biocrust structure responds to soil variables along a tropical scrubland elevation gradient

Biocrusts are composed of diverse organisms including bryophytes, lichens, archaea, bacteria, cyanobacteria, microfungi, and green algae. While biocrusts are distributed worldwide, most of our knowledge comes from temperate regions, and scarce information is available from tropical regions. We aimed...
