| Abstract: | Rock varnish from Arizona's Whipple Mountains harbors a microbial community containing about 108 microorganisms g−1 of varnish. Analyses of varnish phospholipid fatty acids and rRNA gene libraries reveal a community comprised of mostly Proteobacteria but also including Actinobacteria, eukaryota, and a few members of the Archaea. Rock varnish represents a significant niche for microbial colonization. |
