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.

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. Soil significantly positively correlated alpha‐diversity bacteria but not fungi. We also found improved by altering abundance keystone species. classified as module hubs bacterial co‐occurrence network contributed contrast, categorized fungal negatively affected pH key driver community indicating increase under had crucial role biological processes.

Community succession of the grapevine fungal microbiome in the annual growth cycle

Environmental Microbiology, Год журнала: 2020, Номер 23(4), С. 1842 - 1857

Summary Microbial ecology and activity in wine production influences grapevine health productivity, conversion of sugar to ethanol during fermentation, aroma, quality distinctiveness. Fungi the vineyard ecosystem are not well described. Here, we characterized spatial temporal dynamics fungal communities associated with (grapes, flowers, leaves, roots) soils over an annual growth cycle two vineyards investigate grape habitat, plant developmental stage (flowering, fruit set, veraison, harvest), vineyards, climatic conditions. were influenced by both habitat development stage. The core microbiome was prioritized space time, identified members drove seasonal community succession. where grapes undergo a dramatic change metabolism start accumulating sugar, coincided distinct shift communities. Co‐occurrence networks showed strong correlations between microbiome, soil weather indices. Our study describes complex ecological that occur microbial assemblages growing season highlight succession vineyards.

Abundant fungal and rare bacterial taxa jointly reveal soil nutrient cycling and multifunctionality in uneven-aged mixed plantations

Uneven-aged silvicultural practices can maintain habitat continuity and enhance biodiversity. Soil microorganisms play critical roles in multiple ecosystem functions (i.e., multifunctionality). However, little is currently known regarding the role of microbial community driving soil nutrient cycling multifunctionality (SMF) uneven-aged mixed plantations. In this study, we investigated bacterial fungal compositions diversities, single-function related carbon (C), nitrogen (N), phosphorus (P) cycling, SMF indices monoculture plantation (as a control) three stands (4, 7, 11 years old). Our results demonstrated that C, N, P plantations increased by 17.9–55.2%, 20.0–54.0%, 0.7–21.6%, 16.3–30.1% compared to plantation. The alpha diversity (richness Shannon diversity), significantly improved with stand age, but showed less variation. beta diversities bacteria fungi notable variation age were predominantly affected properties (soil organic total P, C/N ratio), respectively. Additionally, temporal turnover within was higher than rates community. biomass more sensitive structure change over short period (11 years) biomass. Furthermore, fungi/bacteria (F/B) ratio strongly positively correlated SMF. Most importantly, abundant taxa (e.g., Mucoromycota Mortierellomycota) major drivers SMF, followed rare Nitrospirae Elusimicrobia). These findings indicate communities have different responses undertake important maintaining when converted into an
