Diversity of microorganisms within rock varnish in the Whipple Mountains, California

Article Abstract:

Rock varnish from Arizona's Whipple Mountains harbors a microbial community containing 10(super 8) microorganisms g(super -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.

Frequency of secondary symbiont infection in an invasive Psyllid relates to parasitism pressure on a geographic scale in California

Article Abstract:

The survey results of diversity and frequency of secondary symbiont, Glycaspis brimblecombei, harbored within the red gum lerp pysllid in California are presented. The findings suggest that symbiont infection frequencies are related to parasitism pressure by a solitary endoparasitoid of the psyllid.

Microbial community diversity associated with carbon and nitrogen cycling in permeable shelf sediments

Article Abstract:

A study was conducted to characterize in detail microbially diverse communities in permeable shelf sands that have a large role in global biogeochemical cycles. Predominant phylotypes that could catalyze carbon and nitrogen cycling in marine sands were revealed.
