Land conversion to agriculture induces taxonomic homogenization of soil microbial communities globally

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: April 29, 2024

Abstract Agriculture contributes to a decline in local species diversity and above- below-ground biotic homogenization. Here, we conduct continental survey using 1185 soil samples compare microbial communities from natural ecosystems (forest, grassland, wetland) with converted agricultural land. We combine our results global meta-analysis of available sequencing data that cover more than 2400 across six continents. Our combined demonstrate land conversion taxonomic functional homogenization bacteria, mainly driven by the increase geographic ranges taxa croplands. find 20% phylotypes are decreased 23% increased conversion, croplands enriched Chloroflexi, Gemmatimonadota, Planctomycetota, Myxcoccota Latescibacterota . Although there is no significant difference composition between land, genes involved nitrogen fixation, phosphorus mineralization transportation depleted cropland. provide insight into consequences land-use change on diversity.

Intranational synergies and trade-offs reveal common and differentiated priorities of sustainable development goals in China

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: March 13, 2024

Abstract Accelerating efforts for the Sustainable Development Goals requires understanding their synergies and trade-offs at national sub-national levels, which will help identify key hurdles opportunities to prioritize them in an indivisible manner a country. Here, we present importance of 17 goals through synergy trade-off networks. Our results reveal that 19 provinces show highest SDG13 (Combating Climate Change) or SDG5 (Gender Equality) consistent with level, other 12 varying. 24 SDG1 (No Poverty) SDG6 (Clean Water Sanitation) remaining 7 These common but differentiated SDG priorities reflect ensure coordinated response, China should pay more attention provincial situation, so governments can formulate targeted policies line own towards accelerating sustainable development.

Spatial and temporal evolution analysis of ecological security pattern in Hubei Province based on ecosystem service supply and demand analysis

Ecological Indicators, Journal Year: 2024, Volume and Issue: 162, P. 112051 - 112051

Published: April 23, 2024

Realizing the superior stability of natural resources for regional economic growth depends on construction Ecological Security Pattern (ESP)1. The ESP Hubei Province was determined based supply and demand ecosystem services (ESSD)2. main conclusions are as follows: (1) overall in exceeds demand, imbalance between Wuhan, Xiangyang Jingzhou is most serious. (2) largest ecological source area 2000 90,506 km2, followed by 86,946 km2 2020. (3) 11 long-term obstacles with a total 312.96 were identified, which mainly composed large areas cultivated land water. (5) protection restoration pattern "two axes, three belts, four districts five cores (two secondary)" has been constructed Province. results this study provide reference management response to problems

Stable Soil Biota Network Enhances Soil Multifunctionality in Agroecosystems

Global Change Biology, Journal Year: 2025, Volume and Issue: 31(1)

Published: Jan. 1, 2025

ABSTRACT Unraveling how agricultural management practices affect soil biota network complexity and stability these changes relate to processes functions is critical for the development of sustainable agriculture. However, our understanding knowledge still remains unclear. Here, we explored effects intensity on complexity, stability, multifunctionality, as well relationships among factors. Four typical land use types representing a gradient disturbance were selected in calcareous red soils southwest China. The four with increasing included pasture, sugarcane farmland, rice paddy fields, maize cropland. cohesion, topological features (e.g., average degree, clustering coefficient, path length, diameter, graph density, modularity), variation degree used evaluate strength interactions between species, respectively. results showed that intensive increased species competition but decreased stability. Soil microfauna nematode, protozoa, arthropoda) stabilized entire through top‐down control. rather than or biodiversity predicted dynamics multifunctionality. Specifically, stable communities, both organism groups archaea, bacteria, fungi, arthropoda, viridiplantae, viruses), support high In particular, had more contributions multifunctionality microbial communities. This result was further supported by analysis, which modules 1 4 greater numbers explained Our study highlights should be considered key factor improving sustainability crop productivity context global intensification.

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

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.

Biodiversity post‐2020: Closing the gap between global targets and national‐level implementation

Conservation Letters, Journal Year: 2021, Volume and Issue: 15(2)

Published: Nov. 21, 2021

Abstract National and local governments need to step up efforts effectively implement the post‐2020 global biodiversity framework of Convention on Biological Diversity halt reverse worsening trends. Drawing recent advances in interdisciplinary science, we propose a for improved implementation by national subnational governments. First, identification actions promotion ownership across stakeholders recognize multiple values account remote responsibility. Second, cross‐sectorial mainstreaming should adopt scalable multifunctional ecosystem restoration approaches target positive futures nature people. Third, assessment progress adaptive management can be informed novel monitoring modeling handling multidimensionality change.
