The ISME Journal, Journal Year: 2021, Volume and Issue: 15(8), P. 2474 - 2489

Abstract While soil erosion drives land degradation, the impact of on microbial communities and multiple functions remains unclear. This hinders our ability to assess true ecosystem services restore eroded environments. Here we examined effect at two sites with contrasting texture climates. Eroded plots had lower network complexity, fewer taxa, associations among relative non-eroded plots. Soil also shifted community composition, decreased abundances dominant phyla such as Proteobacteria, Bacteroidetes, Gemmatimonadetes. In contrast, led an increase in some bacterial families involved N cycling, Acetobacteraceae Beijerinckiaceae. Changes microbiota characteristics were strongly related erosion-induced changes multifunctionality. Together, these results demonstrate that has a significant negative diversity functionality.

Rare taxa maintain the stability of crop mycobiomes and ecosystem functions

Environmental Microbiology, Journal Year: 2020, Volume and Issue: 23(4), P. 1907 - 1924

Published: Sept. 30, 2020

Plants harbour highly diverse mycobiomes which sustain essential functions for host health and productivity. However, ecological processes that govern the plant-mycobiome assembly, interactions their impact on ecosystem remain poorly known. Here we characterized role community assembly of both abundant rare fungal taxa along soil-plant continuums (rhizosphere, phyllosphere endosphere) in maize-wheat/barley rotation system under different fertilization practices at two contrasting sites. Our results indicate mycobiome is shaped predominantly by compartment niche species rather than environmental factors. Moreover, crop-associated communities are dominated few mainly belonging to Sordariomycetes Dothideomycetes, while majority diversity within represented taxa. For plant compartments, sub-community determined stochastic processes. In contrast, more sensitive selection governed deterministic Furthermore, our demonstrate play an important co-occurrence network functioning like crop yield soil enzyme activities. These significantly advance understanding highlight key sustaining stability functions.

Soil bacterial taxonomic diversity is critical to maintaining the plant productivity

Environment International, Journal Year: 2020, Volume and Issue: 140, P. 105766 - 105766

Published: May 3, 2020

Soil microbial communities play a central role in driving multiple ecosystem functions and ecological processes that are key to maintaining the plant productivity. However, we lack sound evidence for linkage between soil diversity productivity, which hinders our ability predict consequences of loss food security under context global environmental change. Here, used dilution-to-extinction approach test aboveground biomass glasshouse experiment. Compared with original soils, bacterial alpha-diversity (Observed operational taxonomic units Shannon index) significantly decreased treatments serially diluted inoculum. Principal coordinates analysis showed overall community compositions (beta-diversity) soils were clearly separated from The lettuce harvested was higher than sterilized regardless inoculation. ordinary least squares regression model significant linear relationship alpha-diversity, indicating reduction could result decline lettuce. No correlation observed including basal respiration denitrification rates. Structural equation models suggested effects on maintained even when simultaneously accounting other drivers (soil properties biological processes). Our study provides experimental is important maintenance productivity suggests functional redundancy may be overestimated especially agroecological system.

Environmental adaptation is stronger for abundant rather than rare microorganisms in wetland soils from the Qinghai‐Tibet Plateau

Molecular Ecology, Journal Year: 2021, Volume and Issue: 30(10), P. 2390 - 2403

Published: March 14, 2021

Disentangling the biogeographic patterns of rare and abundant microbes is essential in order to understand generation maintenance microbial diversity with respect functions they provide. However, little known about ecological assembly processes environmental adaptation across large spatial-scale wetlands. Using Illumina sequencing multiple statistical analyses, we characterized taxonomic phylogenetic bacteria fungi Qinghai-Tibet Plateau wetland soils. Abundant taxa exhibited broader thresholds stronger signals for traits than ones. By contrast, showed higher sensitivity changes closer clustering The null model analysis revealed that dispersal limitation belonging stochastic process dominated community assemblies bacteria, fungi, while variable selection deterministic governed bacteria. Neutral variation partitioning further confirmed were less environmentally constrained. Soil ammonia nitrogen was crucial factor mediating balance between stochasticity determinism both microbes. may have better potential are dispersed by Our findings extend knowledge ongoing change could facilitate prediction biodiversity loss caused probably climate human activity

Microbial diversity and the abundance of keystone species drive the response of soil multifunctionality to organic substitution and biochar amendment in a tea plantation

Abstract High nitrogen (N) fertilizer inputs accelerate soil acidification and degradation in tea plantations, thus posing a threat to microbial diversity, species composition, ecosystem service functions. The effects of organic biochar applications on improving fertility have been extensively studied cropland; however, little is known about their effectiveness promoting multifunctionality rapidly expanding acidic soils plantations. In this study, we conducted two‐year field experiment subtropical plantation investigate the substitution amendment communities multifunctionality. results showed that was enhanced plots amended with biochar.
