Abstract Natural forest succession after disturbances is one of the most important restoration strategies. However, responses ecosystem multifunctionality during natural remains poorly understood in ecosystem. Here we evaluated how including nutrient cycling, carbon stocks, water regulation, decomposition, wood production and symbiosis develops using a chronosequence, identified key factors contributing to variations succession. We provide evidence that gradually increased along with stages. The individual functions stocks regulation also exhibited increasing patterns stand development. microbial diversity were more principal than plant soil properties for explanation changes multifunctionality. regression analysis showed bacteria, general fungi, actinomycetes, nematodes, G + bacteria − significantly positively associated Soil nematodes positive correlation functions. Synthesis applications . Taken together, our results demonstrate plays role promoting multifunctionality, emphasize importance maintenance health.

Soil microbial biodiversity promotes crop productivity and agro-ecosystem functioning in experimental microcosms

Soil biota contribute substantially to multiple ecosystem functions that are key for geochemical cycles and plant performance. However, soil biodiversity is currently threatened by land-use intensification, a mechanistic understanding of how loss interacts with the myriad intensification elements (e.g., application chemical fertilizers) still unresolved. Here we experimentally simplified biological communities in microcosms test whether changes microbiome influenced multifunctionality including crop productivity (leek, Allium porrum). Additionally, half were fertilized further explore different levels interact nutrient additions. Our experimental manipulation achieved significant reduction alpha-diversity (45.9 % bacterial richness, 82.9 eukaryote richness) resulted complete removal taxa (i.e., arbuscular mycorrhizal fungi). community simplification led an overall decrease multifunctionality; particularly, retention capacity reduced biodiversity. Ecosystem was positively correlated (R = 0.79). Mineral fertilizer had little effect on compared reduction, but it leek nitrogen uptake from decomposing litter 38.8 %. This suggests natural processes organic acquisition impaired fertilization. Random forest analyses revealed few members protists Paraflabellula), Actinobacteria Micolunatus), Firmicutes Bacillus) as indicators multifunctionality. results suggest preserving diversity eukaryotic within agroecosystems crucial ensure provisioning functions, particularly those directly related essential services such food provision.

Trophic interactions in soil micro‐food webs drive ecosystem multifunctionality along tree species richness

Global Change Biology, Journal Year: 2024, Volume and Issue: 30(3)

Published: March 1, 2024

Abstract Rapid biodiversity losses under global climate change threaten forest ecosystem functions. However, our understanding of the patterns and drivers multiple functions across gradients remains equivocal. To address this important knowledge gap, we measured simultaneous responses (nutrient cycling, soil carbon stocks, organic matter decomposition, plant productivity) to a tree species richness gradient 1, 4, 8, 16, 32 in young subtropical forest. We found that had negligible effects on nutrient productivity, but stocks multifunctionality significantly increased with richness. Linear mixed‐effect models showed organisms, particularly arbuscular mycorrhizal fungi (AMF) nematodes, elicited greatest relative multifunctionality. Structural equation revealed indirect mediated by trophic interactions micro‐food webs. Specifically, significant negative effect gram‐positive bacteria nematode abundance (a top‐down effect), positive AMF biomass bottom‐up effect). Overall, study emphasizes significance multitrophic perspective elucidating biodiversity‐multifunctionality relationships highlights conservation functioning webs maintain
