Abstract Micro/nanoplastic (MNP) pollution in soil ecosystems has become a growing environmental concern globally. However, the comprehensive impacts of MNPs on health have not yet been explored. We conducted hierarchical meta‐analysis over 5000 observations from 228 articles to assess broad parameters (represented by 20 indicators relevant crop growth, animal health, greenhouse gas emissions, microbial diversity, and pollutant transfer) whether depended MNP properties. found that exposure significantly inhibited biomass germination, reduced earthworm growth survival rate. Under exposure, emissions gases (CO 2 , N O, CH 4 ) were increased. caused decrease bacteria diversity. Importantly, magnitude impact soil‐based was dependent dose size; however, there is no significant difference type (biodegradable conventional MNPs). Moreover, As uptake plants, but promoted plant Cd accumulation. Using an analytical hierarchy process, we quantified negative as mean value −10.2% (−17.5% −2.57%). Overall, this analysis provides new insights for assessing potential risks ecosystem functions.

Multiple facets of global change affect the earth system interactively, with complex consequences for ecosystem functioning and stability. Simultaneous climate biodiversity are particular concern, because may contribute to resistance resilience mitigate impacts. Yet, extent generality how interact remain insufficiently understood, especially decomposition organic matter, a major determinant biosphere–atmosphere carbon feedbacks. With an inter-biome field experiment using large rainfall exclusion facilities, we tested drought, common prediction models many parts world, in decomposer drive forest ecosystems interactively. Decomposing leaf litter lost less (C) nitrogen (N) five different biomes following partial compared conditions without exclusion. An increasing complexity community alleviated drought effects, full compensation when large-bodied invertebrates were present. Leaf mixing increased diversity species richness, which contributed counteracting effects on C N loss, although much smaller degree than complexity. Our results show at relevant spatial scale covering distinct zones that both, communities plant floors have strong potential dynamics during decomposition. Preserving multiple trophic levels contributes appears critical maintain processes under ongoing change.

Photovoltaic power stations: an opportunity to promote European semi-natural grasslands?

Frontiers in Environmental Science, Год журнала: 2023, Номер 11

Опубликована: Июнь 22, 2023

European semi-natural grasslands are particularly species-rich and provide many ecosystem services but depend on extensive land management. Today, these ecosystems highly threatened by abandonment, use intensification habitat destruction. The increasing construction of solar parks may contribute to destruction also an opportunity restore or even create grasslands. We studied ten along a climate gradient in Southern France evaluate the establishment managed grazing. compared plots outside under panels terms plant community composition, soil biodiversity functioning test whether hamper this establishment. different microclimate strongly affected species composition reduced abundance mesofauna biomass fungi gram-negative bacteria.

Perspectives: Regenerative forestry – Managing forests for soil life

Forest Ecology and Management, Год журнала: 2024, Номер 554, С. 121674 - 121674

Опубликована: Янв. 3, 2024

Current forestry policies and practices give little consideration to stewarding forest soils as living ecosystems. I propose five that promote soil biodiversity function. 1. Maintain roots by minimizing the proportion of harvested areas more than 10 m from a tree stem. 2. Fertilize stands at rates maintain C flux belowground, make use species with N-fixing associates. 3. Include functionally phylogenetically diverse species, especially broadleaf in conifer plantations. 4. types ensure all development stages are represented forested landscapes. 5. Monitor quality harvest only when metrics meet or exceed those measured start rotation. Stewarding life function will foster resilience managed forests.

Urbanization accelerates habitat fragmentation and leads to the decline of biodiversity in cities. Urban greenway landscapes provide not only social functions but also important ecological services. In this study, taxonomic richness, abundance, diversity, distribution soil meso- microfauna were investigated three different urban assess their environmental quality. that had a richer tree species composition, higher deciduous ratios, wider greenspace, moderate temperature moisture, lower bulk density less lead conducive survival development community. Different fauna groups varied responses conditions landscapes. Microarthropods more sensitive plant communities; contrast, moisture was most abiotic driver for hygrophilous meso-micro fauna. Our study highlights importance trees rich litter input, wide greenspace its buffering effect on various disturbances, which promote conservation

Herbal leys (multispecies swards) can potentially deliver greater agronomic and environmental benefits than conventional grass-clover swards in grazed agroecosystems. However, despite their popularity agri-environment schemes, little is known about the effect of herbal on soil physical (e.g., porosity), chemical carbon), biological fauna) characteristics. In UK, a 2-ha replicated-field experiment utilising or ley (n = 3 per sward) aimed to investigate sward type quality. Each was rotationally by weaned lambs (3.2 LU ha−1) over two grazing seasons, with physiochemical characteristics assessed after 2-years using techniques such as X-ray micro-Computed Tomography (µCT) microbial shallow shotgun sequencing.

Plant–microbial relations have not yet been fully disclosed in natural or seminatural ecosystems, nor novel ecosystems developing spontaneously on post-coal mine heaps. The aim of this study was to determine which factor, biotic (plant taxonomic diversity vs. plant functional diversity) abiotic (physicochemical substrate parameters), affects the biomass soil microbial communities most, as well situ respiration ecosystems. carried out unreclaimed plots selected according four different combinations and diversity. Additionally, a reclaimed heap served comparison between two management types. several groups analysed using phospholipid fatty acids profiles. We detected that more impacted by parameters (explaining 23% variance) than 12% variance). Particularly, we observed pH most important factor shaping community biomass, shown RDA analysis. highest found with low This finding can be explained fact these represented advanced phase vegetation development early stages succession.
