A fundamental challenge in soil macroecology is to understand how microbial community structure shapes ecosystem function along environmental gradients of the land surface at broad spatial scales (i.e. horizontal dimension). However, little known about structure–function relationships extreme environments depth finer vertical Here, we propose a general dimension partitioning approach for assessing patterns and drivers across simultaneously. We leveraged 200‐km desert salinity gradient created by 12‐year saline‐water irrigation Tarim basin Taklamakan Desert. Specifically, using linear model, hierarchical variance partitioning, path assessed key ecological processes controlling turnover β‐diversity) enzymatic activity relevant carbon, nitrogen, phosphorus cycling study sites (horizontal dimension) depths (vertical found decoupled relationship between β‐diversity activity.

Our findings suggest that dispersal limitation controls heterogeneity, rather than salinization, Taken together, this work highlights face ongoing alterations, under‐explored must be considered conservation efforts critical factor determining environments.

Unveiling the influence of seawater intrusion and vegetation type on coastal arbuscular mycorrhizal fungal communities in China

Land Degradation and Development, Journal Year: 2024, Volume and Issue: 35(16), P. 4935 - 4947

Abstract Continuously rising sea levels pose severe threats to the diversity and stability of coastal ecosystems. However, responses endospheric rhizospheric arbuscular mycorrhizal (AM) fungal communities accelerated seawater intrusion changing vegetation types unfortunately remains unknown. Such insights will assist in revealing structure AM fungi across different tidal zones, enabling development effective measures conserve biodiversity. Here, we investigated changes associated with four Dafeng City, Jiangsu Province, China, response level variations by analyzing their characteristics connections selected environmental factors. It was found that differed significantly compositions, diversity, (the resilience or resistance a community). Despite soil factors, electrical conductivity, cation exchange content, inorganic carbon were identified as core elements influenced between species. Lastly, major species important predictors explained much variation environment. Consequently, dynamics correlated plant–soil system under conditions. Apart from species, can also be driven high salinity content induced seawater.

pH Nonlinearly Dominates Soil Bacterial Community Assembly along an Altitudinal Gradient in Oak-Dominant Forests

Microorganisms, Journal Year: 2024, Volume and Issue: 12(9), P. 1877 - 1877

Published: Sept. 11, 2024

Soil bacteria, the predominant microbiota in soil, are subject to law of minimum and tolerance, but assembly patterns soil bacteria response environmental factors remain far from clear. Here, we took advantage an altitudinal gradient (1020-1770 asl) oak-dominant forests assessed whether linearly or nonlinearly respond properties through changes community diversity composition. We found that decreased with increasing altitude terms species richness phylogenetic structure, while they were unchanged The was affected by pH (19.9%), C:N ratio (14.3%), SOC (11.4%), silt + clay content (9.9%). Specifically, peaked at a 5.5-6.5, 25-50 g kg

Soil salinization has become a major global ecosystem sustainability issue. In Senegal, promising restoration of salt-affected lands been achieved by the implementation ecological engineering strategies based on beneficial associations between Casuarina species and salt-tolerant symbiotic microorganisms. However, extent impacts symbiont inoculants native soil microbiota and, consequently, functioning is fragmentary. The current study aimed to evaluate changes in associated with use inoculant mixed Casuarinaceae plantations lands. Symbiont inoculation led decrease diversity fungi but not bacteria. whole structure was impacted inoculation, as case for salinity Casuarina species. species also dominant taxa constituting microbiota, only affected bacterial diversity. Important modifications functionalities were revealed, notably, abundance pathogens related an increase fungal increasing salinity. nutrient cycling, mostly micronutrient cycling N fixation, main factors affecting soil.
