Geographic and environmental sources of variation in lake bacterial community composition

Article Abstract:

A study was carried out to reveal that the lake bacterial community composition displayed coherent geographical variation on both regional and landscape scales, and bacterial communities in different lakes may also display coherent temporal variation. The importance of spatial and temporal structure in the community ecology of pelagic lake bacteria is highlighted.

Aerobic anoxygenic photosynthesis in Roseobacter clade bacteria from diverse marine habitats

Article Abstract:

Research has been conducted on Roseobacter clade strains from different marine habitats. The diversity of these strains has been investigated via the use of 16S rRNA gene as a phylogenetic marker in the effort to correlate phylogeny with ecology, and the results are discussed.

Genome organization and localization of the pufLM genes of the photosynthesis reaction center in phylogenetically diverse marine alphaproteobacteria

Article Abstract:

Pulse-field gel electrophoresis in marine phototrophic alphaproteobacteria is used to study genome organization, plasmid content and localization of pufLM genes. The methods and results are discussed.
