Differential mechanisms underlying responses of soil bacterial and fungal communities to nitrogen and phosphorus inputs in a subtropical forest [PDF]
PeerJ, 2019 Atmospheric nitrogen (N) deposition and phosphorus (P) addition both can change soil bacterial and fungal community structure with a consequent impact on ecosystem functions.

Journal of Integrative Agriculture, 2021 Microbes are decomposers of crop residues, and climatic factors and residue composition are known to influence microbial growth and community composition, which in turn regulate residue decomposition.

The Importance of Dispersal for Bacterial Community Composition and Functioning
PLoS ONE, 2011 We conducted a metacommunity experiment to investigate the role of dispersal for bacterial community composition (BCC) and function of freshwater bacteria. Bacteria were dispersed from a common source pool into three different lake communities in their natural lake water.

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.

Resolving environmental drivers of microbial community structure in Antarctic soils [PDF]
, 2009 Antarctic soils are extremely cold, dry, and oligotrophic, yet harbour surprisingly high bacterial diversity. The severity of environmental conditions has constrained the development of multi-trophic communities, and species richness and distribution is ...

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 ...

The bacterial community composition of the surface microlayer in a high mountain lake [PDF]
FEMS Microbiology Ecology, 2010 The existence of bacterioneuston in aquatic ecosystems is well established, but little is known about its composition and dynamics, particularly in lakes. The bacterioneuston underlies extreme conditions at the air-water boundary, which may influence its dynamics in a different way compared with the bacterioplankton.

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.
