Soil bacteria are largely missing from future biodiversity assessments hindering comprehensive forecasts of ecosystem changes. Soil bacterial communities are expected to be more strongly driven by pH and less by other edaphic and climatic factors. Thus, alkalinisation or acidification along with climate change may influence soil bacteria, with subsequent influences for example on nutrient cycling and vegetation. Future forecasts of soil bacteria are therefore needed. We applied species… 

The activity and functions of soil microbial communities in the Finnish sub-Arctic vary across vegetation types

Increased microbial activity in high-latitude soils due to climate change might lead to higher greenhouse gas (GHG) emissions. However, mechanisms of microbial GHG production and consumption in

The activity and functions of subarctic soil microbial communities vary across vegetation types

This work analyzed 116 soil metatranscriptomes from 73 tundra sites and investigated how bacterial and archaeal communities and their functions vary horizontally and vertically during the summer season, in soil types that differed in pH, moisture, soil organic matter, and carbon and nitrogen content.

Patterns and ecological drivers of viral communities in acid mine drainage sediments across Southern China

Recent advances in environmental genomics have provided unprecedented opportunities for the investigation of viruses in natural settings. Yet, our knowledge of viral biogeographic patterns and the

Microbial landscape ecology: landscape structure better predicts soil protist diversity than local edaphic variables in alpine meadows

Context: Human-induced changes in landscape structure are among the main causes of biodiversity loss. However, despite their important contribution to biodiversity and ecosystem functioning, microbes

Distinct rhizosphere soil responses to nitrogen in relation to microbial biomass and community composition at initial flowering stages of alfalfa cultivars

In the long-term growth process, alfalfa rhizosphere forms specific microbiome to provide nutrition for its growth and development. However, the effects of different perennial alfalfa cultivars on

Comparative analysis of diversity and environmental niches of soil bacterial, archaeal, fungal and protist communities reveal niche divergences along environmental gradients in the Alps

It was showed that microorganisms have well defined niches, as do macro-organisms, likely driving part of the observed spatial patterns of community variations, and that edaphic properties were the most important drivers of both community diversity and composition for all microbial groups.

In this article we present with STATA regression models suitable for analyzing over-dispersed count outcomes. Specifically, the Negative Binomial regression can be an appropriate choice for modeling



Existing Climate Change Will Lead to Pronounced Shifts in the Diversity of Soil Prokaryotes

It is predicted that soil bacterial diversity will increase across the majority of the Tibetan Plateau and northern North America if bacterial communities equilibrate with existing climatic conditions.

Biogeography and habitat modelling of high-alpine bacteria.

A nested sampling scheme is used at scales ranging from 2 to 2,000 m to show that bacteria have significant spatial autocorrelation in community composition up to a distance of 240 m, and that this pattern is driven by changes in the relative abundance of specific bacterial clades across the landscape.

Soil Properties Drive Microbial Community Structure in a Large Scale Transect in South Eastern Australia

It is revealed that soil microbes along a 1000 km transect have unique spatial structures that are governed mainly by soil properties, which contributed the most to the microbial distribution, while other environmental factors showed lesser impact.

Soil Microbial Community Responses to Multiple Experimental Climate Change Drivers

The results indicate that climate change drivers and their interactions may cause changes in bacterial and fungal overall abundance; however, changes in precipitation tended to have a much greater effect on the community composition.

Mapping the niche space of soil microorganisms using taxonomy and traits.

The biodiversity of microbial communities has important implications for the stability and functioning of ecosystem processes. Yet, very little is known about the environmental factors that define

Climate change alters ecological strategies of soil bacteria.

By clustering relative abundance patterns, this work identified three discrete ecological strategies and found that tolerance to drying-rewetting increased with exposure to intensified rainfall patterns, which may be predictable from disturbance history, and are likely to be linked to traits that influence the functional potential of microbial communities.

Mapping and predictive variations of soil bacterial richness across France

The overall objectives of this study were to describe the bacterial taxonomic richness variations across France, to identify the ecological processes influencing this distribution, and to develop a statistical predictive model of soil bacterial richness.

Local Environmental Factors Drive Divergent Grassland Soil Bacterial Communities in the Western Swiss Alps

An in-depth biogeographical characterization of the bacterial community diversity in this alpine region across 100 randomly stratified sites, using 56 environmental variables to address the question of how microbial communities in alpine regions are dependent on local climatic and soil physicochemical variables.

A global atlas of the dominant bacteria found in soil

This study narrows down the immense number of bacterial taxa to a “most wanted” list that will be fruitful targets for genomic and cultivation-based efforts aimed at improving the understanding of soil microbes and their contributions to ecosystem functioning.
