Correlation between microbial communities and volatile organic compounds in an urban soil provides clues on soil quality towards sustainability of city flowerbeds

Heliyon, Journal Year: 2023, Volume and Issue: 10(1), P. e23594 - e23594

Published: Dec. 12, 2023

Soil functionality is critical to the biosphere as it provides ecosystem services relevant for a healthy planet. The soil microbial composition significantly impacted by anthropogenic activities, including urbanization. In this context, study of microorganisms associated urban green spaces has started be crucial toward sustainable city development. Microbes living in produce and degrade volatile organic compounds (VOCs). VOC profiles may used distinguish between soils with various characteristics management practices, reflecting variations activity microbes that use variety metabolic pathways. Here, combined approach based on DNA metabarcoding GC-MS analysis was evaluate quality from flowerbeds Prato (Tuscany, Italy) terms biodiversity emission profiles, final aim evaluating possible correlation community patterns. Results showed VOCs considered originated anthropic biological activity, significant correlations specific taxa were detected. Overall, demonstrated feasibility microbe-VOC proxy assessment soils.

Urbanized lands degrade surrounding grasslands by deteriorating the interactions between plants and soil microbiome

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

Published: Jan. 6, 2025

To mitigate overgrazing on grasslands, towns were constructed in some pastoral regions of China to relocate pastoralists. Nevertheless, whether and how the urbanized lands impact surrounding grassland ecosystem remains unclear. We assessed impacts plant soil interactions within grasslands order ensure an eco-sustainable pastoralist relocation. The town with 1 km radius was selected as urbanization sample a nature sample. Plants investigated (NG), areas (T-1 km), 2 (T-2 3 (T-3 km) from center town. In T-1 T-2 km, compared NG, diversity, abundance dominant species, wood saprotroph fungi, water content (SWC), total organic carbon (TOC) decreased, while pathogen pH, phosphatase (TP) increased. Conversely, no such changes observed T-3 km. results Mantel test Partial least squares path model suggest that decrease TOC SWC, along increase pH TP lead decline fungi ultimately resulting reductions diversity species. These indicate can degradation by deteriorating plant-soil interactions.

Fungal Community Dynamics in Cyperus rotundus: Implications for Rhizophora mangle in a Mangrove Ecosystem

International Journal of Plant Biology, Journal Year: 2025, Volume and Issue: 16(1), P. 23 - 23

Published: Feb. 19, 2025

Mangrove ecosystems are globally significant for their biodiversity and ecosystem services but face persistent threats from invasive species anthropogenic disturbances. This study investigates the interactions between Cyperus rotundus, a widespread weed, fungal communities in mangrove-adjacent wetlands of Isla Santay, Ecuador. Using metagenomic sequencing ITS region, we analyzed diversity samples an anthropogenically pressured area non-impacted site. Results revealed differences microbial assemblages: rhizosphere sample disturbed exhibited lower richness was dominated by Magnaporthaceae (9%) Aureobasidium melanogenum (5%), both associated with stress-tolerant traits. In contrast, site showed higher diversity, Cladosporium dominicanum (62%) Talaromyces (11%) as dominant endophytic taxa. Principal Coordinates Analysis (PCoA) co-occurrence networks highlighted distinct partitioning two tissues, indicating that C. rotundus mediates composition response to environmental gradients. These findings underscore role plant’s success suggest leveraging beneficial fungi could enhance resilience support wetland restoration. By integrating molecular approaches ecological insights, this work contributes deeper understanding dynamics coastal informs targeted management strategies preserve mangrove habitats.

Treatments included (1) continuous application of chemical fertilisers for 27 years (CF-CF); (2) continuously 24 then organic 3 (CF-OF); (3) (OF-OF); (4) (OF-CF). The results show that alters genus-level taxa, while mode changes significantly increase taxa quantities at both phylum genus levels. Different treatments affect the relative abundance bacteria; Firmicutes OF-OF is greater than CF-CF, Gemmatimonadota Patescibacteria opposite trend. Compared CF-OF increases decreases Cyanobacteria, whereas OF-CF compared OF-OF. Notably, enriched Cyanobacteria Bacteroidota are CF-OF, Myxomycophyta treatment. composition CF-CF similar, similar. In assembly processes, improves heterogeneous selection process reduces homogeneous dispersal gradually becomes similar CF-OF.

Published: March 25, 2025

The tree microbiome is a critical determinant of and ecosystem functioning, but human disturbances can disrupt natural microbe-tree relationships. Here, we show that urban trees exhibit microbial dysbiosis along model urbanization gradient, with declines in mutualistic root leaf symbionts, increases decomposers pathogens, including those relevant to plant, animal, health. These shifts correlate stressors such as heat, drought, atmospheric deposition. Urban microbiomes also altered biogeochemical cycling capabilities, high potential for nitrogen loss through greenhouse gas (N2O) production reduced capacity methane consumption relative rural trees. Additionally, reduces overall diversity, particularly among non-pathogenic microbes, potentially diminishing the ecological health benefits diverse environmental cities. findings underscore need consider forestry management practices maximize city greening forest conservation efforts.

Urbanization alters fungal functional composition in boreal ecosystems by favouring larger‐spore fungi and pathogenic fungi

Functional Ecology, Journal Year: 2025, Volume and Issue: unknown

Published: April 7, 2025

Abstract Urbanization is a major threat to biodiversity, ultimately influencing ecosystem functions. Fungi, highly taxonomically and functionally diverse group of organisms, underpin many these functions from nutrient cycling symbiotic interactions. Yet, research on how urbanization impacts fungal diversity has primarily focused detecting changes in community structure, rather than understanding the functional implications changes. Here we examined shifts dispersal resource‐use traits due boreal ecosystems. We hypothesized that urban sites may favour large‐spored taxa as they be better suited survive germinate under harsher conditions. Conversely, small‐spored could dominate fragmented habitats, their spores can disperse over longer distances. turnover guilds altered substrates hosts versus natural settings. To test hypotheses, cross‐referenced data five Finnish cities adjacent naturally‐forested areas obtained via metabarcoding with databases spore size guilds. found consistent dominance environments, suggesting greater impact abiotic stress communities habitat fragmentation are believed possess survival structures for germination stressful In terms groups, taxa, such pathogens affecting lichens, plants, animals (including humans), showed an increase abundance This pattern suggests dual effect urbanization, by introducing new susceptible creating conditions existing ones, favouring infections pathogenic fungi.
