Biogeographic distribution patterns of bacteria in typical Chinese forest soils

open access: yesFrontiers in Microbiology, 2016
Microbes are widely distributed in soils and play a very important role in nutrient cycling and ecosystem services. To understand the biogeographic distribution of forest soil bacteria, we collected 115 soil samples in typical forest ecosystems across ...

Influences of soil properties on archaeal diversity and distribution in the McMurdo Dry Valleys, Antarctica [PDF]

open access: yes, 2011
The Antarctic Dry Valleys are characterized by extremely low temperatures, arid conditions, high salinity and virtual absence of plants. Therefore, food webs of these microbially dominated soils are among the simplest on earth making these mineral soils ...

Diversity-triggered deterministic bacterial assembly constrains community functions [PDF]

open access: yesNature Communications, 2019
AbstractA growing body of evidence suggests that microbial α-diversity (local species richness) may have positive effects on ecosystem function. However, less attention has been paid to β-diversity (the variation among local microbial assemblages).

Variations in Soil Bacterial Composition and Diversity in Newly Formed Coastal Wetlands

open access: yesFrontiers in Microbiology, 2019
Coastal ecosystems experience some of the most active land–ocean interactions in the world, and they are characterized by high primary productivity and biological diversity in the sediment. Given the roles of microorganisms in soil biogeochemical cycling

Analysis of a change in bacterial community in different environments with addition of chitin or chitosan [PDF]

open access: yes, 2010
The temporal changes of a bacterial community in soil with chitin or chitosan added were analyzed by PCR-denaturing gradient gel electrophoresis (DGGE) targeting the 16S rRNA gene using total DNAs prepared from the community.

Changes in the bacterial community structure and diversity during bamboo retting [PDF]

open access: yesBiotechnology Journal, 2011
AbstractMicrobial retting is a critical step in obtaining fiber bundles from bamboo culm using indigenous microorganisms. A cultivation‐independent technique for monitoring the changes in bacteria community during bamboo retting was applied in this work. This technique involves genetic profiling of PCR‐amplified small‐subunit rRNA and the single‐strand

Community ecology of denitrifying bacteria in arable land [PDF]

open access: yes, 2008
Denitrifying bacteria comprise a functional guild that under anaerobic conditions is able to use nitrogenous compound for respiration. Agricultural soils are often fertilized with nitrogen, and the reduction of nitrate and nitrite to nitric oxide ...

Truffle Brûlés Have an Impact on the Diversity of Soil Bacterial Communities

open access: yesPLoS ONE, 2013
The development of Tuber melanosporum mycorrhizal symbiosis is associated with the production of an area devoid of vegetation (commonly referred to by the French word 'brûlé') around the symbiotic plants and where the fruiting bodies of T. melanosporum are usually collected. The extent of the ecological impact of such an area is still being discovered.

Resource diversity structures aquatic bacterial communities [PDF]

open access: yes, 2018
ABSTRACT Microbial diversity is strongly affected by the bottom-up effects of resource availability. However, because resource pools often exist as heterogeneous mixtures of distinct molecules, resource heterogeneity may also affect community diversity.

Day-length is central to maintaining consistent seasonal diversity in marine bacterioplankton [PDF]

open access: yes, 2010
Marine bacterial diversity is vast, but seasonal variation in diversity is poorly understood. Here we present the longest bacterial diversity time series consisting of monthly (72) samples from the western English Channel over a 6 year period (2003-2008)
