Resistance and resilience responses of a range of soil eukaryote and bacterial taxa to fungicide application [PDF]

open access: yes, 2014
The application of plant protection products has the potential to significantly affect soil microbial community structure and function. However, the extent to which soil microbial communities from different trophic levels exhibit resistance and ...

Bacteria in heavy metal contaminated soil: diversity, tolerance and use in remediation [PDF]

open access: yes, 2010
The objectives of this project were to determine the bacterial diversity in a heavily contaminated metal region of Portugal. Both traditional and molecular based methods were used to identify tolerant strains and species. The most tolerant species were

Effect of pH on soil bacterial diversity [PDF]

open access: yesJournal of Ecology and Environment, 2016
In order to evaluate the effect of pH, known as a critical factor for shaping the biogeographical microbial patterns in the studies by others, on the bacterial diversity, we selected two sites in a similar geographical location (site 1; north latitude 35.3, longitude 127.8, site 2; north latitude 35.2, longitude 129.2) and compared their soil bacterial

Identifying the Biogeographic Patterns of Rare and Abundant Bacterial Communities Using Different Primer Sets on the Loess Plateau

open access: yesMicroorganisms, 2021
High-throughput sequencing is commonly used to study soil microbial communities. However, different primers targeting different 16S rRNA hypervariable regions often generate different microbial communities and result in different values of diversity and ...

How Do Soil Bacterial Diversity and Community Composition Respond under Recommended and Conventional Nitrogen Fertilization Regimes?

open access: yesMicroorganisms, 2020
Shifts in soil bacterial diversity and community composition are suggested to be induced by elevated input of nitrogen (N) fertilization with implications for soil quality, and consequently production.

Empirical and Theoretical Bacterial Diversity in Four Arizona Soils [PDF]

open access: yesApplied and Environmental Microbiology, 2002
ABSTRACT Understanding patterns of biodiversity in microbial communities is severely constrained by the difficulty of adequately sampling these complex systems. We illustrate the problem with empirical data from small surveys (200-member 16S rRNA gene clone libraries) of four bacterial soil communities from two locations in ...
