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

Scientific Reports, Journal Year: 2018, Volume and Issue: 8(1)

Published: July 31, 2018

Abstract Soil microbial communities directly affect soil functionality through their roles in the cycling of nutrients and carbon storage. Microbial vary substantially space time, between types under different land management. The mechanisms that control spatial distributions microbes are largely unknown as we have not been able to adequately upscale a detailed analysis microbiome few grams catchment, region or continent. Here reveal along 1000 km transect unique structures governed mainly by properties. community assessed using Phospholipid Fatty Acids showed strong gradient latitude across New South Wales, Australia. We found properties contributed most distribution, while other environmental factors (e.g., temperature, elevation) lesser impact. Agricultural activities reduced variation communities, however, its influence was local much less than overall ability predict distribution will allow us how future change microbes.

The Microbiome Stress Project: Toward a Global Meta-Analysis of Environmental Stressors and Their Effects on Microbial Communities

Frontiers in Microbiology, Journal Year: 2019, Volume and Issue: 9

Published: Jan. 10, 2019

Microbial community structure is highly sensitive to natural (e.g., drought, temperature, fire) and anthropogenic heavy metal exposure, land-use change) stressors. However, despite an immense amount of data generated, systematic, cross-environment analyses microbiome responses multiple disturbances are lacking. Here, we present the Microbiome Stress Project, open-access database environmental host-associated 16S rRNA amplicon sequencing studies collected facilitate cross-study This will comprise published unpublished datasets re-processed from raw sequences into exact sequence variants using our standardized computational pipeline. Our provide insight general response patterns diversity, structure, stability It also enable identification associations between single or stressors specific microbial clades. a proof-of-concept meta-analysis 606 microbiomes (from nine studies) assess to: (1) one stressor in environment: soil warming across variety types, (2) range comprehensive set (incl. diesel, antibiotics, land use change, metals), (3) environments: copper exposure effects on soil, sediment, activated-sludge reactors, gut environments, (4) trends responses. Overall, found that significantly decreases alpha diversity increases beta (community dispersion) environments types. We observed hump-shaped relationship resistance (i.e., average pairwise similarity score control stressed communities) diversity. used Phylofactor identify clades individual taxa as potential bioindicators contamination different environments. Using statistical methods, Project leverage thousands existing build framework for how communities respond stress.

Microbial Biostimulants as Response to Modern Agriculture Needs: Composition, Role and Application of These Innovative Products

Plants, Journal Year: 2021, Volume and Issue: 10(8), P. 1533 - 1533

Published: July 27, 2021

An increasing need for a more sustainable agriculturally-productive system is required in order to preserve soil fertility and reduce biodiversity loss. Microbial biostimulants are innovative technologies able ensure agricultural yield with high nutritional values, overcoming the negative effects derived from environmental changes. The aim of this review was provide an overview on research related plant growth promoting microorganisms (PGPMs) used alone, consortium, or combination organic matrices such as (PBs). Moreover, effectiveness role microbial biological tool improve fruit quality limit degradation discussed. Finally, increased use these products requires achievement accurate selection beneficial consortia, ability prepare future agriculture challenges. Hence, implementation microorganism positive list provided by EU (2019/1009), desirable.

Minor Effects of Warming on Soil Microbial Diversity, Richness and Community Structure

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(3)

Published: March 1, 2025

ABSTRACT Climate warming has caused widespread global concern. However, how affects soil microbial diversity, richness, and community structure on a scale remains poorly understood. Here we conduct meta‐analysis of 945 observations from 100 publications by collecting relevant data. The results show that field experiments significantly modify temperature (+1.8°C), water content (−3.2%), pH (−0.04). does not alter the bacteria fungi. Warming‐induced changes in variables (i.e., ΔSoil content, ΔpH), ΔTemperature experimental duration are important factors influencing responses to warming. In addition, bacterial α‐diversity (Shannon index) decreases (−3.4%) when is 3–6 years, β‐diversity increases (35.2%) exceeds 6 years. Meta‐regression analysis reveals positive correlation between change Shannon index ΔpH. Moreover, produces more pronounced effects fungal sites with moderate mean annual (MAT, 0°C–10°C) than higher (> 10°C) or lower (< 0°C) MAT. Overall, this study provides perspective response microorganisms climate improves our knowledge

Alpine soil microbial ecology in a changing world

FEMS Microbiology Ecology, Journal Year: 2018, Volume and Issue: 94(9)

Published: May 25, 2018

ABSTRACT Climate change has a disproportionally large impact on alpine soil ecosystems, leading to pronounced changes in microbial diversity and function associated with effects biogeochemical processes at the local supraregional scales. However, due restricted accessibility, high-altitude soils remain largely understudied considerable heterogeneity hampers comparability of different studies. Here, we highlight differences similarities between arctic discuss climatic variables vegetation properties ecology. We consider how alpha-diversity, community structures along altitudinal gradients other topographic features such as slope aspect. In addition, focus permafrost soils, harboring surprisingly unknown succession glacier forefield chronosequences constituting most thoroughly studied habitat. Finally, highlighting experimental approaches, present climate studies showing shifts response warming altered moisture, interestingly some contradiction. Collectively, despite harsh environmental conditions, many specially adapted microorganisms are able thrive environments. Their strongly correlate climatic, thus closely mirror complexity small-scale soils.
