Soil microbial community and influencing factors of different vegetation restoration types in a typical agricultural pastoral ecotone

Frontiers in Microbiology, Journal Year: 2025, Volume and Issue: 15

Published: Jan. 23, 2025

Microbial network complexity is an important indicator for assessing the effectiveness of vegetation restoration. However, response microbial bacteria and fungi to different restoration types unclear. Therefore, in this study, we selected four ( Pinus sylvestris var. mongholica , Larix principis- rupprechtii Populus tomentosa Ulmus pumila ), while nature grassland as a control, Zhangjiakou Tunken Forest Farm, which typical agricultural pastoral ecotone northern China, investigate soil diversity types. Our result showed that bacterial Shannon Chao indices P. were significantly 7.77 22.39% higher than those 20–40 cm layer, respectively. The fungal U. 85.70 146.86% 40–60 Compared natural grassland, networks became more complex plantation forests L. ). increased with carbon nitrogen. suitable planting Zhangjiakou, because its high carbon, nitrogen complexity. Bacterial community composition was found be closely related organic (SOC), total (TN), SOC, clay silt content. This improvement enhances ecological service function ecotone. These findings offer theoretical basis technical support ecologically fragile areas

Soil Microorganisms: Their Role in Enhancing Crop Nutrition and Health

Diversity, Journal Year: 2024, Volume and Issue: 16(12), P. 734 - 734

Published: Nov. 29, 2024

Maintaining soil health is fundamental to sustaining agricultural productivity, however, the intricate role of microbial diversity in this process not fully understood. Current research acknowledges that microorganisms including bacteria, fungi, and archaea are pivotal driving essential functions such as nutrient cycling, organic matter decomposition, disease suppression. However, impacts global environmental changes intensive practices on these remain a critical gap literature. This significant because decline could severely compromise health, consequently crop productivity. Here, we provide comprehensive review factors influencing examine their implications for performance. We assess both natural pH, moisture, temperature, vegetation type well human-induced tillage systems fertilizer application. The synthesizes recent findings how shape communities functional roles structure formation, Our analysis highlights mechanisms by which enhances plant growth yield, addressing understanding direct links between outcomes. underscore urgent need sustainable protect enhance safeguard long-term fertility By challenges manipulating integrating ecology with management practices, advances our ability sustain face changes.

Community diversity and composition affect ecosystem multifunctionality across environmental gradients in boreal and temperate forests

Ecological Indicators, Journal Year: 2024, Volume and Issue: 159, P. 111692 - 111692

Published: Feb. 1, 2024

Biodiversity is known to affect ecosystem functioning, and environmental stress may influence the relationships between biodiversity functions (BEF). However, it still unknown how relationship multifunctionality (BEMF) varies with environment at regional scale. We aimed explore change of BEMF across gradients in boreal temperate forest ecosystems, identify main impact mechanisms on EMF. Based a data set collected Northeastern China, we quantified EMF by calculating average six individual functions, defined species richness functional diversity as community diversity, community-weighted means traits composition. used multifactorial linear regression assess effect indices BEMF, structural equation models among factors Community composition, well their interactions gradients, were jointly influencing In forests, composition was dominant driver became factor impacting The results imply that changes conditions. mainly influenced (mass ratio effect) forests. greater leads resource utilization thus (niche complementarity effect).

Results showed that (O) significantly increased alpha diversity, niche width network complexity community compared (C). The with suspension were recolonization. Soil inoculated (OO) was 14.6% 70.6% higher than rest treatments. Macrogenomic analysis revealed O enriched functional pathways ABC transporters, carbon metabolism, biosynthesis amino acids, two‐component nitrogen metabolism as well most genes for degradation, fixation, cycling phosphorus cycles C.
