Temporal Dynamics of the Human Vaginal Microbiota
TLDR
The temporal dynamics of the composition of vaginal bacterial communities in 32 reproductive-age women over a 16-week period revealed the dynamics of five major classes of bacterial communities and showed that some communities change markedly over short time periods, whereas others are relatively stable.
Characterization of the Diversity and Temporal Stability of Bacterial Communities in Human Milk
TLDR
The conclusion that human milk, which is recommended as the optimal nutrition source for almost all healthy infants, contains a collection of bacteria more diverse than previously reported is supported.
Advances in the use of terminal restriction fragment length polymorphism (T-RFLP) analysis of 16S rRNA genes to characterize microbial communities
TLDR
The progress made in T-RFLP analysis of 16S rRNA and genes allows researchers to make methodological and statistical choices appropriate for the hypotheses of their studies.
The vaginal bacterial communities of Japanese women resemble those of women in other racial groups.
TLDR
The limited number of community types found among women in different ethnic groups suggests that host genetic factors may be more important in determining the species composition of vaginal bacterial communities than are cultural and behavioral differences.
Bacterial succession in a glacier foreland of the High Arctic
TLDR
It is suggested that bacterial succession occurs in High Arctic glacier forelands but may differ in different soil depths, although statistically significant differences between sampling locations in the surface and mineral soils could be demonstrated even though glacierForelands are patchy and dynamic environments.
Bacterial diversity in a glacier foreland of the high Arctic
TLDR
The level of bacterial diversity present in this High Arctic glacier foreland was comparable with that found in temperate and tropical soils, raising the question whether global patterns of bacterial species diversity parallel that of plants and animals, which have been found to form a latitudinal gradient and be lower in polar regions compared with the tropics.
Combined Flux Chamber and Genomics Approach Links Nitrous Acid Emissions to Ammonia Oxidizing Bacteria and Archaea in Urban and Agricultural Soil.
TLDR
The results suggest that biogenic HONO emissions will be important in soil environments that exhibit high nitrification rates (e.g., agricultural soil) although the widespread occurrence of ammonia oxidizers implies thatBiogenic HonO emissions are also possible in the urban and remote environment.
Unanticipated Geochemical and Microbial Community Structure under Seasonal Ice Cover in a Dilute, Dimictic Arctic Lake
TLDR
For the first time, the importance of PSB as potential sulfur oxidizers in an Arctic dimictic lake is shown, and a 13-fold increase in sulfide at the oxycline was reflected in an increase and change in community composition of potential sulfur oxidation.
Effect of permafrost thaw on plant and soil fungal community in a boreal forest: Does fungal community change mediate plant productivity response?
Permafrost thaw is leading to rapid shifts in boreal ecosystem function. Permafrost thaw affects soil carbon turnover through changes in soil hydrology; however, the biotic mechanisms regulating
