Organism body size structures the soil microbial and nematode community assembly at a continental and global scale

Nature Communications, Journal Year: 2020, Volume and Issue: 11(1)

Published: Dec. 17, 2020

Body size is a key life-history trait that influences community assembly by affecting how ecological processes operate at the organism level. However, extent to which relative of mediate differentially sized soil organisms still unknown. Here, we investigate microorganisms and microfauna using continental-scale sampling effort combined with global-scale meta-analysis. Our results reveal general relationship between body stochastic-deterministic balance operating on assembly. The smallest (bacteria) are relatively more influenced dispersal-based stochastic processes, while larger ones (fungi, protists nematodes) structured selection-based deterministic processes. This study elucidates significant consistent an distinct in mediating their respective assemblages, thus providing better understanding mechanisms supporting biodiversity.

Trends in Microbial Community Composition and Function by Soil Depth

Published: Feb. 28, 2022

Microbial communities play important roles in soil health, contributing to processes such as the turnover of organic matter and nutrient cycling. As edaphic properties chemical composition physical structure change from surface layers deeper ones, microbiome similarly exhibits substantial variability with depth, respect both community functional profiles. However, studies often neglect soils, instead focusing on top layer soil. Here, we provide a synthesis how its resident depth. We touch upon physicochemical properties, microbial diversity, composition, profiles, special emphasis carbon In doing so, seek highlight importance incorporating analyses soils studies.

Soil microbial subcommunity assembly mechanisms are highly variable and intimately linked to their ecological and functional traits

Molecular Ecology, Journal Year: 2024, Volume and Issue: 33(7)

Published: Feb. 29, 2024

Abstract Revealing the mechanisms underlying soil microbial community assembly is a fundamental objective in molecular ecology. However, despite increasing body of research on overall mechanisms, our understanding subcommunity for different prokaryotic and fungal taxa remains limited. Here, soils were collected from more than 100 sites across southwestern China. Based amplicon high‐throughput sequencing iCAMP analysis, we determined various taxa. The results showed that dispersal limitation homogenous selection primary drivers this region. highly variable. For instance, contribution to Crenarchaeota was 70%, but it only around 10% Actinomycetes, Gemmatimonadetes Planctomycetes. subcommunities including with higher occurrence frequencies, average relative abundance network degrees, as well wider niches tended be influenced by homogenizing drift, less affected heterogeneous limitation. also varied substantially among functional guilds. Notably, diazotrophs, nitrifiers, saprotrophs some pathogens predominantly controlled selection, while denitrifiers mainly stochastic processes such drift. These findings provide novel insights into diversity maintenance analysis pipeline holds significant value future research.

What drives study‐dependent differences in distance–decay relationships of microbial communities?

Global Ecology and Biogeography, Journal Year: 2021, Volume and Issue: 30(4), P. 811 - 825

Published: Feb. 8, 2021

Abstract Aim Ecological communities that exist closer together in space are generally more compositionally similar than those far apart, as defined by the distance–decay of similarity relationship. However, recent research has revealed substantial variability relationships microbial between studies different taxonomic groups, ecosystems and spatial scales using molecular methodologies (e.g., high‐throughput sequencing versus fingerprinting). Here, we test how these factors influence strength relationships, order to draw generalizations about β‐diversity with space. Location Global. Time period Studies published 2005 2019 (inclusive).

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

Ecological Indicators, Journal Year: 2021, Volume and Issue: 129, P. 107932 - 107932

Published: June 28, 2021

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.

These findings indicate communities have different responses undertake important maintaining when converted into an

Phytopathogenic fungi threaten global food security but the ecological drivers of their diversity and biogeography remain unknown. Here, we construct analyse a atlas potential phytopathogenic from 20,312 samples across all continents major oceanic island regions, eleven land cover types, twelve habitat types. We show peak in mid-latitude contrast to latitudinal gradients observed aboveground organisms. Our study identifies climate as an important driver distribution fungi, our models suggest that invasion will increase globally by 2100. Importantly, phytopathogen largely forest (37.27-79.12%) cropland (34.93-82.51%) ecosystems, this becomes more pronounced under fossil-fuelled industry dependent future scenarios. Thus, recommend improved biomonitoring forests croplands, optimised sustainable development approaches reduce threats fungi.
