Aridity-driven shift in biodiversity–soil multifunctionality relationships

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Sept. 9, 2021

Relationships between biodiversity and multiple ecosystem functions (that is, multifunctionality) are context-dependent. Both plant soil microbial diversity have been reported to regulate multifunctionality, but how their relative importance varies along environmental gradients remains poorly understood. Here, we relate multifunctionality across 130 dryland sites a 4,000 km aridity gradient in northern China. Our results show strong positive association species richness less arid regions, whereas diversity, particular of fungi, is positively associated with more regions. This shift the relationships or occur at an level ∼0.8, boundary semiarid climates, which predicted advance geographically ∼28% by end current century. study highlights that loss plants microorganisms may especially consequences under low high conditions, respectively, calls for climate-specific conservation strategies mitigate effects aridification.

Decreased soil multifunctionality is associated with altered microbial network properties under precipitation reduction in a semiarid grassland

Published: May 1, 2023

Our results reveal different responses of soil multifunctionality to increased and decreased precipitation. By linking microbial network properties functions, we also show that complexity potentially competitive interactions are key drivers multifunctionality.

Grassland degradation-induced declines in soil fungal complexity reduce fungal community stability and ecosystem multifunctionality

Soil Biology and Biochemistry, Journal Year: 2022, Volume and Issue: 176, P. 108865 - 108865

Published: Oct. 29, 2022

Soil microorganisms are major regulators of ecosystem functioning and under threat from human-induced disturbances. Among these threats is grassland degradation, which estimated to affect 49% the area worldwide, threatening biodiversity functioning. Yet, we currently lack an understanding how degradation influences belowground microbial communities, their stability, functioning, effective restoration efforts for recovery important properties. Here, assessed soil fungal network complexity a suite functions along well-characterised gradient on Qinghai-Tibetan Plateau, conducted accompanying microcosm experiment designed test effects stability in communities. We found that with increasing levels communities became less complex were compositionally stable when confronted drought laboratory conditions. Moreover, this degradation-induced reduction community was associated lower multifunctionality. However, multifunctionality failed recover even after ten years restoration. Our results indicate simplification can potentially impair multifunctionality, thereby highlighting need protect restore healthy grasslands • Grassland resulted drought. Degradation-induced Fungal

Afforestation can lower microbial diversity and functionality in deep soil layers in a semiarid region

Global Change Biology, Journal Year: 2022, Volume and Issue: 28(20), P. 6086 - 6101

Published: July 9, 2022

Afforestation is an effective approach to rehabilitate degraded ecosystems, but often depletes deep soil moisture. Presently, it not known how afforestation-induced decrease in moisture affects microbial community and functionality, hindering our ability understand the sustainability of rehabilitated ecosystems. To address this issue, we examined impacts 20 years afforestation on bacterial community, co-occurrence pattern, functionalities along vertical profile (0-500 cm depth) a semiarid region China's Loess Plateau. We showed that effects with deep-rooted legume tree cropland were greater than top layers, resulting decreased beta diversity, more responsive taxa functional groups, increased homogeneous selection, network robustness soils (120-500 cm). Organic carbon nitrogen decomposition rates multifunctionality also significantly by afforestation, limitation soils. Moreover, changes functionality layer was largely related Such negative should be fully considered for assessing afforestation's eco-environment ecosystems because have important influence forest arid climates.

Acidification suppresses the natural capacity of soil microbiome to fight pathogenic Fusarium infections

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Aug. 22, 2023

Soil-borne pathogens pose a major threat to food production worldwide, particularly under global change and with growing populations. Yet, we still know very little about how the soil microbiome regulates abundance of their impact on plant health. Here combined field surveys experiments investigate relationships properties structure function contrasting health outcomes. We find that acidification largely impacts bacterial communities reduces capacity soils combat fungal pathogens. In vitro assays microbiomes from acidified further highlight declined ability suppress Fusarium, globally important pathogen. Similarly, when inoculate healthy plants an microbiome, show greatly reduced prevent pathogen invasion. Finally, metagenome sequencing untargeted metabolomics reveals down regulation genes associated synthesis sulfur compounds reduction key traits related metabolism in acidic soils. Our findings suggest changes disruption specific microbial processes induced by can play critical role for

Experimental impacts of grazing on grassland biodiversity and function are explained by aridity

Grazing by domestic herbivores is the most widespread land use on planet, and also a major global change driver in grasslands. Yet, experimental evidence long-term impacts of livestock grazing biodiversity function largely lacking. Here, we report results from network 10 sites paired grazed ungrazed grasslands across an aridity gradient, including some largest remaining native planet.
