Quantifying relative contributions of biotic interactions to bacterial diversity and community assembly by using community characteristics of microbial eukaryotes

Ecological Indicators, 2023
Biotic interactions are known as a major control on microbial diversity. However, biotic interactions have rarely been quantified in an adequate manner, often leaving much residual variation unexplained in microbial biogeographic studies.

Topographic diversity of fungal and bacterial communities in human skin [PDF]

Nature, 2013
Traditional culture-based methods have incompletely defined the microbial landscape of common recalcitrant human fungal skin diseases, including athlete's foot and toenail infections. Skin protects humans from invasion by pathogenic microorganisms and provides a home for diverse commensal microbiota. Bacterial genomic sequence data have generated novel

Influence of Fecal Sample Storage on Bacterial Community Diversity [PDF]

The Open Microbiology Journal, 2009
Previous studies have identified a correlation, either positive or negative, between specific stool bacteria strains and certain autoimmune diseases. These conflicting data may relate to sample collection. The aim of this work was to evaluate the influence of the collection parameters of time and temperature on ...

Sediment enzyme activities and microbial community diversity in an oligotrophic drinking water reservoir, eastern China. [PDF]

PLoS ONE, 2013
Drinking water reservoir plays a vital role in the security of urban water supply, yet little is known about microbial community diversity harbored in the sediment of this oligotrophic freshwater environmental ecosystem. In the present study, integrating

Soil Bacterial Diversity Responds to Long-Term Establishment of Perennial Legumes in Warm-Season Grassland at Two Soil Depths

Microorganisms, 2023
The introduction of rhizoma peanut (RP Arachis glabrata Benth) into bahiagrass (Paspalum notatum Flüggé) may require time to develop stable plant–soil microbe interactions as the microbial legacy of the previous plant community may be long-lasting.

Diversity of Human Vaginal Bacterial Communities and Associations with Clinically Defined Bacterial Vaginosis [PDF]

Applied and Environmental Microbiology, 2008
ABSTRACT Bacterial vaginosis (BV) is a common syndrome associated with numerous adverse health outcomes in women. Despite its medical importance, the etiology and microbial ecology of BV remain poorly understood. We used broad-range PCR to census the community structure of the healthy and BV-affected vaginal microbial ecosystems ...

Effects of Reforestation on the Structure and Diversity of Bacterial Communities in Subtropical Low Mountain Forest Soils

Frontiers in Microbiology, 2018
Reforestation with different tree species could alter soil properties and in turn affect the bacterial community. However, the effects of long-term reforestation on bacterial community structure and diversity of subtropical forest soils are poorly ...

Wildfire effects on diversity and composition in soil bacterial communities

Science of The Total Environment, 2020
In recent years, the Mediterranean area has witnessed an increase of both the frequency and severity of large fires, which appears to be intimately associated with climate and land use changes. To measure the impact of wildfires on living organisms, diverse indicators have been proposed.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

FEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Warming enhances the effects of nitrogen addition on fungal but not on bacterial diversity in an alpine meadow

Basic and Applied Ecology
Warming and nitrogen (N) deposition significantly affect soil microbial community characteristics. However, the responses of bacterial and fungal diversity to warming and N deposition, as well as the dominant influencing factors, remain unclear ...
