Wildfire effects on diversity and composition in soil bacterial communities
Science of the Total Environment, 2020 In recent years, the Mediterranean area has witnessed an increase of both the frequency and severity of large fires, which appears to be intimately associated with climate and land use changes. To measure the impact of wildfires on living organisms, diverse indicators have been proposed.

Assessing bacterial diversity in soil
Journal of Soils and Sediments, 2008Biodiversity has been defined as the total number of species present, i.e. species richness or species abundance, and the distribution of individuals among those species, i.e. species evenness or species equitability. Recently, the biodiversity of soil biota is becoming increasingly essential with the requirement of preserving the integrity, function ...

Bacterial diversity in paclobutrazol applied agricultural soils
Journal of Environmental Science and Health, Part B, 2010The aim of this study was to investigate the bacterial communities on paclobutrazol [(2RS, 3RS)-1-(4-Chlorophenyl)-4, 4-dimethyl-2-(1H-1,2,4-triazol-1-yl) pentan-3-ol]-applied agricultural soils by denaturing gradient gel electrophoresis (DGGE) of polymerase chain reaction (PCR) amplified 16S rDNA gene fragments.

Testing association between soil bacterial diversity and soil carbon storage on the Loess Plateau
Science of the Total Environment, 2018 Bacteria are widely distributed and play an important role in soil carbon (C) cycling. The impact of soil bacterial diversity on soil C storage has been well established, yet little is known about the underlying mechanisms and the interactions among them.

Spatial Stratification of Soil Bacterial Populations in Aggregates of Diverse Soils
Microbial Ecology, 2006Most soil microbial community studies to date have focused on homogenized bulk soil samples. However, it is likely that many important microbial processes occur in spatially segregated microenvironments in the soil leading to a microscale biogeography. This study attempts to localize specific microbial populations to different fractions or compartments

Characterization of the bacterial archaeal diversity in hydrocarbon-contaminated soil
Science of The Total Environment, 2012A polyphasic approach combining culture-based methods with molecular methods is useful to expand knowledge on microbial diversity in contaminated soil. Microbial diversity was examined in soil samples from a former industrial site in the European Alps (mainly used for aluminum production and heavily contaminated with petroleum hydrocarbons) by culture ...

The Diversity of Bacterial Communities in Urban Soils
Eurasian Soil Science, 2018Urbanozems (Urbic Technosols) contaminated by heavy metals and polychlorbiphenyls (Urbic Technosols Toxic) and intruzems (Urbic Technosols Toxic) were studied in Moscow; additionally, we studied recreazems (Urbic Technosols Thaptohumic) and culturozems (Urbic Technosols Pantohumic) on the territory of the Botanical Garden of Moscow State University ...

Bacterial diversity in soils around a lead and zinc mine
Journal of Environmental Sciences, 2007Five samples of soil collected from a lead and zinc mine were used to assess the effect of combined contamination of heavy metals on soil bacterial communities using a polyphasic approach including characterization of isolates by culture method, community level catabolic profiling in BIOLOG GN microplates, and genetic community fingerprinting by ...

Bacterial Community Diversity in the Brazilian Atlantic Forest Soils
Microbial Ecology, 2010The aim of this study was to characterize the bacterial community diversity of the Brazilian Atlantic forest soil by means of both cultivation and 16S rRNA clone libraries. A collection of 86 representative isolates, obtained from six samples of Atlantic forest soils from the National Park of Serra dos Órgãos (PARNASO), belonged to the genera ...
