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 ...

It is elemental: soil nutrient stoichiometry drives bacterial diversity [PDF]
Environmental Microbiology, 2017 Summary It is well established that resource quantity and elemental stoichiometry play major roles in shaping below and aboveground plant biodiversity, but their importance for shaping microbial diversity in soil remains unclear. Here, we used statistical modeling on a regional database covering 179 locations and six ecosystem types ...

Light structures phototroph, bacterial and fungal communities at the soil surface [PDF]
, 2013 The upper few millimeters of soil harbour photosynthetic microbial communities that are structurally distinct from those of underlying bulk soil due to the presence of light. Previous studies in arid zones have demonstrated functional importance of these

Zinc contamination decreases the bacterial diversity of agricultural soil [PDF]
FEMS Microbiology Ecology, 2003 Abstract Around half a million tonnes of biosolids (sewage sludge dry solids) are applied to agricultural land in the United Kingdom each year, and this may increase to 732 000 t by 2005/6. The heavy metals contained in biosolids may permanently degrade the microbial decomposer communities of agricultural soils.

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 ...

Bacterial diversity in soils of different Hungarian karst areas [PDF]
Acta Microbiologica et Immunologica Hungarica, 2018 Karst areas have great environmental importance as sources of subsurface water and often maintain very sensitive ecosystems. In recent years, increasing number of microbiological studies focused on the bacterial communities of karst soils. In this study, diversity examinations on two distinct Hungarian karst areas, Aggtelek and Tapolca, were performed ...

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.

Diversity analysis of Streptomycetes and associated phosphotranspherase genes in soil [PDF]
, 2012 An attempt was made to verify the observation that Streptomyces griseus was prevalent in soil based on isolation work. A genus-specific PCR was developed for Streptomyces based on the housekeeping gene atpD and used to investigate species diversity ...

Microbial diversity determines the invasion of soil by a bacterial pathogen [PDF]
Proceedings of the National Academy of Sciences, 2012 Natural ecosystems show variable resistance to invasion by alien species, and this resistance can relate to the species diversity in the system. In soil, microorganisms are key components that determine life support functions, but the functional redundancy in the microbiota of most soils has long been thought to overwhelm microbial
