Wildfire Impacts Pinus tabulaeformis Forests on Soil Properties, Actinobacteriota, and Enzyme Activity in Northern China: Direct Effects or Mutual Interactions?

Forests, Год журнала: 2025, Номер 16(2), С. 344 - 344

Опубликована: Фев. 14, 2025

Wildfires are significant disturbances that reshape soil ecosystems, impacting properties, microbial communities, and enzyme activities. In Pinus tabulaeformis forests in northern China, the effects of wildfire on health, particularly Actinobacteriota enzymatic functions, remain poorly understood. This study investigates both direct indirect fire severity these factors examines how fire-induced changes properties mediate responses. Our findings show significantly alters chemical including an increase pH a reduction organic carbon water content, under high severities. These directly impact with showing resilience light moderate intensities but declining severity, especially subsoil layers. Soil enzymes, such as urease protease, played crucial role mitigating negative impacts nutrient cycling. Their activity promoted availability, aiding ecosystem recovery, even intensity reduced overall fertility. Structural Equation Modeling (SEM) further revealed relationships between Actinobacteriota, shaped by thermal complex interactions mediated moisture levels. underscores importance considering mutual activities post-fire recovery. The highlight while high-severity fires disrupt health dynamics, enzymes can help regulate enhancing cycling supporting stability. insights contribute to better understanding wildfire-induced degradation provide actionable strategies for restoration management fire-prone ecosystems.

The fate of biodegradable polylactic acid microplastics in maize: impacts on cellular ion fluxes and plant growth

Frontiers in Plant Science, Год журнала: 2025, Номер 16

Опубликована: Фев. 25, 2025

The widespread application of biodegradable microplastics (MPs) in recent years has resulted a significant increase their accumulation the environment, posing potential threats to ecosystems. Thus, it is imperative evaluate distribution and transformation MPs crops due utilization wastewater containing for irrigation plastic films, which have led rising concentration agricultural soils. present study analyzed uptake polylactic acid (PLA) maize. Seed germination hydroponic experiments were conducted over period 5 20 days, during plants exposed PLA at concentrations 0, 1, 10, 100 mg L-1. Low (1 L-1 10 L-1) significantly enhanced maize seed rate by 52.6%, increased plant shoot height 16.6% 16.9%, respectively, as well elevated aboveground biomass dry weight 133.7% 53.3%, respectively. Importantly, depolymerization was observed nutrient solution, resulting formation small-sized (< 2 μm). Interestingly, further occurred within xylem sap apoplast fluid (after 12 h) with reaching 13.1% 27.2%, growth could be attributed dissolved organic carbon from MPs. Additionally, mediated pH K+ flux (57.2%, 72 h), leading acidification cell wall subsequent expansion. Our findings provide evidence regarding fate interactions plants, thereby enhancing our understanding impacts associated plastics.

Recent Insights into Microplastic Pollution and Its Effects on Soil Carbon: A Five-Year Ecosystem Review

Microplastics, Год журнала: 2025, Номер 4(2), С. 18 - 18

Опубликована: Апрель 14, 2025

The widespread presence of microplastics (MPs) is growing concern for both the scientific community and public. Contemporary research increasingly focuses on ecosystem transformation global climate change. We conducted a literature review, consisting 46 studies, to investigate consequences MPs’ influence carbon cycle in different soil types across various ecosystems. MPs can affect cycling compounds other biogenic elements by impacting microbiome, enzyme activity, plant growth, litter decomposition, more. majority authors report increased CO2 and/or CH4 emissions soils containing MPs. However, some studies demonstrate opposite or neutral result, outcomes differ even within single study depending type type, form, size used. Further clarification development our understanding regarding impact ecosystems remain crucial, taking into account inclusion as wide variety possible future research.

Microplastics in the Typical Mulched Farmland of Sichuan Province: Characteristics That Vary Across Farming Scales and the Risk Significantly Contributed by Priority Polymers

Sustainability, Год журнала: 2025, Номер 17(8), С. 3516 - 3516

Опубликована: Апрель 14, 2025

Microplastics (MPs) in agricultural soils pose risks to human health their potential accumulation along the food chain, and characteristics require further understanding implement targeted measures. This study investigated MP typical mulching from different farming scales Sichuan Province, which is one of China’s key regions, it also innovatively measured ecological risk by incorporating size into assessments. The sites showed average microplastic abundances 19696.81 ± 13226.89, these were dominated small-sized ethylene–propylene copolymer (E/P), polypropylene (PP), polyethylene (PE) particles yellow-to-brown black-to-shallow-gray soil. Size-considered evaluation suggested that most at a high level risk. It was found pollution varies with scales. Larger-scale primarily received MPs plastic mulching, while smaller-scale likely affected range non-agricultural sources. assessment significant contributions polyamide (PA) polyphenylene sulfide (PPS). These results indicate environmental management strategies should tailor source control measures according prioritize high-risk polymers, as well evaluations include “size” “pollution load” “chemical composition” better reflect impact on ecosystems.
