Bacterial community structure and diversity in a century-old manure-treated agroecosystem
(American Society for Microbiology, 2004-10)
Changes in soil microbial community structure and diversity may reflect environmental impact. We examined 16S rRNA gene fingerprints of bacterial communities in six agroecosystems by PCR amplification and denaturing gradient ...
Novelty and uniqueness patterns of rare members of the soil biosphere
(American Society for Microbiology, 2008-09)
Soil bacterial communities typically exhibit a distribution pattern in which most bacterial species are present in low abundance. Due to the relatively small size of most culture-independent sequencing surveys, a detailed ...
Microbial community structure in petroleum-contaminated sediments corresponds to geophysical signatures
(American Society for Microbiology, 2007-05)
The interdependence between geoelectrical signatures at underground petroleum plumes and the structures of subsurface microbial communities was investigated. For sediments contaminated with light non-aqueous-phase liquids, ...
Prevalence and genotypes of Anaplasma species and habitat suitability for ticks in a Mediterranean ecosystem
(American Society for Microbiology, 2008-12)
Anaplasma species are tick-transmitted pathogens that impact veterinary and human health. Sicily is one of the locations where these pathogens are endemic. Sicily represents a typical Mediterranean ecosystem to study ...
Phylogenetic and metabolic diversity of Planctomycetes from anaerobic, sulfide- and sulfur-rich Zodletone Spring, Oklahoma
(American Society for Microbiology, 2007-08)
We investigated the phylogenetic diversity and metabolic capabilities of members of the phylum Planctomycetes in the anaerobic, sulfide-saturated sediments of a mesophilic spring (Zodletone Spring) in southwestern Oklahoma. ...
Assessment of the diversity, abundance, and ecological distribution of members of candidate division SR1 reveals a high level of phylogenetic diversity but limited morphotypic diversity
(American Society for Microbiology, 2009-06)
We used a combination of 16S rRNA gene clone library surveys, quantitative PCR (qPCR) analysis, and fluorescent in situ hybridization to investigate the diversity, abundance, and distribution of members of candidate division ...
