Bacterial diversity and community composition changes in paddy soils that have different parent materials and fertility levels

Journal of Integrative Agriculture, 2021
Parent materials and the fertility levels of paddy soils are highly variable in subtropical China. Bacterial diversity and community composition play pivotal roles in soil ecosystem processes and functions.

Tree diversity and functional leaf traits drive herbivore‐associated microbiomes in subtropical China

Ecology and Evolution, 2021
Herbivorous insects acquire microorganisms from host plants or soil, but it remains unclear how the diversity and functional composition of host plants contribute to structuring herbivore microbiomes.

A comparison of rpoB and 16S rRNA as markers in pyrosequencing studies of bacterial diversity [PDF]

, 2012
Background: The 16S rRNA gene is the gold standard in molecular surveys of bacterial and archaeal diversity, but it has the disadvantages that it is often multiple-copy, has little resolution below the species level and cannot be readily interpreted in ...

Effects of nitrogen and phosphorus imbalance input on rhizosphere and bulk soil bacterial community of Suaeda salsa in the Yellow River Delta

Frontiers in Marine Science, 2023
IntroductionThe effects of nitrogen (N) and phosphorus (P) addition on soil microbial diversity have been widely studied, however, the response of bacterial community to N and P imbalance input remains unclear.MethodsUsing a high-throughput Illumina ...

Presence of a loner strain maintains cooperation and diversity in well-mixed bacterial communities [PDF]

, 2016
Cooperation and diversity abound in nature despite cooperators risking exploitation from defectors and superior competitors displacing weaker ones. Understanding the persistence of cooperation and diversity is therefore a major problem for evolutionary ...

Polymicrobial airway bacterial communities in adult bronchiectasis patients [PDF]

, 2014
Background: Chronic airway infection contributes to the underlying pathogenesis of non-cystic fibrosis bronchiectasis (NCFBr). In contrast to other chronic airway infections, associated with COPD and CF bronchiectasis, where polymicrobial communities ...

Differing Prevalence and Diversity of Bacterial Species in Fetal Membranes from Very Preterm and Term Labor [PDF]

, 2009
Background: Intrauterine infection may play a role in preterm delivery due to spontaneous preterm labor (PTL) and preterm prolonged rupture of membranes (PPROM). Because bacteria previously associated with preterm delivery are often difficult to culture,

Determinants of the Bacterial Diversity in Manipulated and Natural Soils [PDF]

, 2008
Soils harbor highly diverse bacterial communities. It is still poorly understood whether functional redundancy or a multitude of ecological niche modify the abundance and community composition of bacteria in soil.

Moderate grazing increased alpine meadow soils bacterial abundance and diversity index on the Tibetan Plateau

Ecology and Evolution, 2020
The response of grassland soil bacterial community characteristics to different grazing intensities is central ecological topics. However, the underlying mechanisms between bacterial abundance, diversity index, and grazing intensity remain unclear.
