ABSTRACT To begin defining the key determinants that drive microbial community structure in soil, we examined 29 soil samples from four geographically distinct locations taken from the surface, vadose zone, and saturated subsurface using a small-subunit rRNA-based cloning approach. While microbial communities in low-carbon, saturated, subsurface soils showed dominance, microbial communities in low-carbon surface soils showed remarkably uniform distributions, and all species were equally… Expand
Environmental controls over bacterial communities in polar desert soils
Productivity-diversity theory has proven informative to many investigations seeking to understand drivers of spatial patterns in biotic communities and relationships between resource availability andExpand
Changes in Bacterial and Archaeal Community Structure and Functional Diversity along a Geochemically Variable Soil Profile
TLDR
Investigating changes in the microbial and functional communities within soil aggregates obtained along a soil profile spanning the surface, vadose zone, and saturated soil environments found that the microbial communities and putative ammonia-oxidizing and Fe(III)-reducing communities varied greatly along the soil profile, likely reflecting differences in carbon availability, water content, and pH. Expand
The Effect of Soil Texture on Richness and Diversity of Bacterial Communities
TLDR
The increase in species richness in coarser soils is likely due to the increased number of isolated water films in soils with larger pores, suggesting that pore-scale hydrologic regime constrains bacterial richness in soil. Expand
High beta diversity of bacteria in the shallow terrestrial subsurface.
TLDR
It is suggested that the high beta diversity of bacteria is likely to be recapitulated in other terrestrial sites because of the great frequency of high geochemical and/or historical variations along depth. Expand
Bacterial community composition of divergent soil habitats in a polar desert.
TLDR
Results show that alpha diversity is significantly lowered in high pH soils, which contain higher proportions of the phyla Acidobacteria and Actinobacteria, while mesic soils with higher soil organic carbon (and ammonium) content contain high proportions of Nitrospira, a nitrite-oxidizing bacteria. Expand
A Two-Species Test of the Hypothesis That Spatial Isolation Influences Microbial Diversity in Soil
TLDR
Analysis of competitive dynamics of two species growing on a single resource in a uniform sand matrix under varied moisture content indicates that spatial isolation, created by low moisture content, plays an important role in structuring soil microbial communities. Expand
Biogeographic Distribution Patterns of Bacteria in Typical Chinese Forest Soils
TLDR
Soil properties and climate conditions (MAT and MAP) greatly accounted for the differences in the soil bacterial structure, and among all soil parameters determined, soil pH predominantly affected the diversity and composition of the bacterial community, and soil pH = 5 probably could be used as a threshold below which soil bacterial diversity might decline and soil bacterial community structure might change significantly. Expand
Bacterial diversity and composition in major fresh produce growing soils affected by physiochemical properties and geographic locations.
TLDR
It was showed that bacterial community composition and diversity in major fresh produce growing soils from California and Arizona is a function of soil physiochemical characteristics and geographic distances of sampling sites. Expand
Spatial heterogeneity of a microbial community in a sandy soil ecosystem
Abstract A fieldwork was carried out in Caesarea sand dunes, Israel, to determine the influence of fine-scale landscape-patch abiotic-factor heterogeneity on microbial activity in a MediterraneanExpand
Soil Microbial Abundance and Diversity Along a Low Precipitation Gradient
TLDR
It is indicated that although soil bacterial abundance decreases with precipitation, bacterial diversity is independent of precipitation gradient and community composition was found to be unique to each ecosystem. Expand

Vertical and Horizontal Variations in the Physiological Diversity of the Aerobic Chemoheterotrophic Bacterial Microflora in Deep Southeast Coastal Plain Subsurface Sediments
TLDR
Subsurface isolates from different geological formations and from the same geological formation at different boreholes differed distinctly in their group responses to certain physiological tests, and considerable bacterial diversity was observed in coastal plain subsurface sediments, even within defined geological formations.

Molecular microbial diversity in soils from eastern Amazonia: evidence for unusual microorganisms and microbial population shifts associated with deforestation
TLDR
This report represents the first description of the microbial diversity in Amazonian soils involving a culture-independent approach and rRNA intergenic spacer analysis was used to show significant microbial population differences between a mature forest soil and an adjacent pasture soil. Expand
Diverse uncultivated bacterial groups from soils of the arid southwestern United States that are present in many geographic regions
TLDR
A phylogenetic survey of microbial species present in two soils from northern Arizona indicates that members of these new groups comprise a phylogenetically diverse, geographically widespread, and perhaps numerically important component of the soil microbiota. Expand
Molecular phylogenetic analysis of a soil microbial community in a soybean field
TLDR
The phylogenetic characterization of small subunit rRNA gene sequences obtained by polymerase chain reaction (PCR) amplification of mixed population DNA extracted directly from soil in a soybean field without culturing the organisms suggests a global distribution of this archaeal group. Expand

Levels of bacterial community diversity in two pinyon rhizosphere soil samples and two between-tree (interspace) soil samples are compared by analyzing 179 cultivated bacterial isolates and 801 16S rRNA genes amplified from extracted soil DNA. Expand
Molecular phylogeny of Archaea from soil.
TLDR
A cluster of Archaea from a soil microbial community that diverge deeply from the crenarchaeotal line of descent and has the closest affiliation to the lineage of planktonic Archaea is identified. Expand
Characterization of the Dominant and Rare Members of a Young Hawaiian Soil Bacterial Community with Small-Subunit Ribosomal DNA Amplified from DNA Fractionated on the Basis of Its Guanine and Cytosine Composition
TLDR
Small-subunit ribosomal DNA diversity was found to be very high in a Hawaiian soil community that might be expected to have lower diversity than the communities in continental soils because the Hawaiian soil is geographically isolated, is subjected to a constant climate, and harbors low plant diversity.

Biogeography and Degree of Endemicity of Fluorescent Pseudomonas Strains in Soil

TLDR
Fluorescent Pseudomonas strains were isolated from 38 undisturbed pristine soil samples from 10 sites on four continents, suggesting that these heterotrophic soil bacteria are not globally mixed. Expand
Phylogenetic diversity of a bacterial community determined from Siberian tundra soil DNA.
TLDR
Most of the tundra soil bacterial community has never been isolated and thus the physiology and function of its dominant members appears to be unknown, suggesting that many probably reflect new genera or families. Expand
