Dispersal alters bacterial diversity and composition in a natural community [PDF]

The ISME Journal, 2017
Abstract Dispersal is central to the evolution and maintenance of microbial diversity. Quantifying microbial dispersal and its role in shaping communities remains a challenge, however. Here, we manipulated a bacterial community’s dispersal rate in a grassland ecosystem and test whether this altered diversity and composition.

Microbial biogeography of arctic streams: exploring influences of lithology and habitat

Frontiers in Microbiology, 2012
Terminal restriction fragment length polymorphism and 16S rRNA gene sequencing were used to explore the community composition of bacterial communities in biofilms on sediments (epipssamon) and rocks (epilithon) in stream reaches that drain watersheds ...

Analysis of Bacterial Community Composition by Oligonucleotide Fingerprinting of rRNA Genes [PDF]

Applied and Environmental Microbiology, 2002
ABSTRACT One of the first steps in characterizing an ecosystem is to describe the organisms inhabiting it. For microbial studies, experimental limitations have hindered the ability to depict diverse communities. Here we describe oligonucleotide fingerprinting of rRNA genes (OFRG), a method that permits identification of arrayed ...

How Microbial Food Web Interactions Shape the Arctic Ocean Bacterial Community Revealed by Size Fractionation Experiments

Microorganisms, 2021
In the Arctic, seasonal changes are substantial, and as a result, the marine bacterial community composition and functions differ greatly between the dark winter and light-intensive summer. While light availability is, overall, the external driver of the

Atmospheric Deposition Impact on Bacterial Community Composition in the NW Mediterranean [PDF]

Frontiers in Microbiology, 2019
Atmospheric deposition is a source of inorganic nutrients and organic matter to the ocean, and can favor the growth of some planktonic species over others according to their nutrient requirements. Atmospheric inputs from natural and anthropogenic sources are nowadays increasing due to desertification and industrialization, respectively.

Composition of the bacterial community in the gastrointestinal tract of Kunming mice

Electronic Journal of Biotechnology, 2020
Background: The intestinal bacterial community has an important role in maintaining human health. Dysbiosis is a key inducer of many chronic diseases including obesity and diabetes.

Species dynamics in natural bacterial communities over multiple rounds of propagation

Evolutionary Applications, 2022
Our experimental work illustrates how microbial ecosystems can be shaped by selective pressures over long‐term ecological time scales. Natural microbial ecosystems generally consist of various co‐existing species, where community composition describes ...

Straw Return and Nitrogen Fertilization to Maize Regulate Soil Properties, Microbial Community, and Enzyme Activities Under a Dual Cropping System

Frontiers in Microbiology, 2022
Soil sustainability is based on soil microbial communities’ abundance and composition. Straw returning (SR) and nitrogen (N) fertilization influence soil fertility, enzyme activities, and the soil microbial community and structure.

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.
