Introduction In recent years, the frequency and intensity of anthropogenic wildfires have drastically increased, significantly altering terrestrial ecosystems worldwide. These fires not only devastate vegetative cover but also impact soil environments microbial communities, affecting ecosystem structure function. The extent to which fire severity, depth, their interaction influence these effects remains unclear, particularly in Pinus tabulaeformis forests. Methods This study investigated wildfire stratification on physicochemical properties diversity within P. forests North China. Soil samples were collected from different severity zones (Control, Light, Moderate, High) depths (topsoil: 0–10 cm; subsoil: 10–20 cm). Analyses included measurements pH, organic carbon (SOC), total nitrogen (TN), other nutrients. Microbial was assessed using 16S rRNA gene sequencing. Results Our findings revealed significant variations SOC, TN, nutrients with profoundly community composition diversity. pH emerged as a critical determinant, closely linked α-diversity structure. We found that altered ( p = 0.001), pointing noteworthy changes acidity varying levels. Topsoil communities primarily differentiated between burned unburned conditions, whereas subsoil layers showed more pronounced structures. Analysis bacterial phyla across levels shifts communities. Proteobacteria consistently dominated all indicating strong resilience, while Acidobacteriota Actinobacteriota increased abundances high-severity light/moderate-severity areas, respectively. Verrucomicrobiota prevalent control decreased fire-impacted soils. Chloroflexi Bacteroidota displayed abundance moderate Correlation analyses illustrated relationships environmental factors dominant phyla.

ABSTRACT Fungi are involved in several biotic processes soil. Many studies have investigated the impacts of wildfire on fungal communities, but few explored their diversity after post‐fire management. This study seeks to fill this gap by evaluating species richness, diversity, and evenness fungi, many soil properties a severely burned forest Central‐Eastern Spain 10 years installing log erosion barriers (LEBs) as management treatment. When compared unburned soils, all indices communities—especially richness abundance, +39%,—significantly increased untreated sites. was mainly due long time elapsed from treatment high cover dead wood, which supported humidity for fungi development. Compared areas, LEBs further biodiversity, +43% +22% abundance. biodiversity higher content organic matter, nutrients, some enzymes. Therefore, used can be suitable development semi‐arid forests affected severe wildfires.

The summer drought in the United Kingdom (UK) 2022 produced significant speculation concerning how its termination may impact and interact with soil resource. Whilst knowledge regarding soils droughts exists scientific literature, a coherent understanding of wider range impacts on properties functions has not been compiled for temperate soils. Here, we draw together from studies UK other countries to understand respond drought, importantly what where our gaps are. First, define different types their frequency provide brief overview likely societal that place related ecosystems. Our focus is ‘agricultural ecosystem drought’, as this when experience dry periods affecting crops function, followed by rewetting. behaviour moisture key processes contribute storage transport are examined. principal changes physical, chemical, biological resulting rewetting (i.e., termination) discussed extensive interactions demonstrated. Processes involved explored catchment-scale responses. Lastly, soils’ recovery after considered, identified, areas improve highlighted.

Fire is a dominant ecosystem process in many Mediterranean climate type ecosystems, and predicted to increase severity frequency, shifting away from previous regimes regions. Responses of flora fauna fire are relatively well studied, but less known about the responses belowground microbiota. We quantified soil fungal dynamics over first 12-15 months after fire, focusing on attributes regime (season, interval, severity). Soil samples were collected three sites threatened woodland southwestern Australia, Mediterranean-type region. Fungal taxa identified via high throughput sequencing ITS subregion taxonomy assigned using reference databases. Richness, diversity, abundance, community composition, functional groups quantified. Over post-fire sampling period, richness diversity declined composition changed significantly throughout with family level groupings experiencing most change. Through an saprotrophic endophytic fungi was observed, along decrease all pathogenic fungi. found that quite dynamic fire. little effect interval or season, though our inference limited. Our work contributes putting biota into same conceptual frameworks as aboveground serves inform managers fire-prone

Environmental disasters are extreme environmental processes such as earthquakes, volcanic eruptions, landslides, tsunamis, floods, cyclones, storms, wildfires and droughts that the consequences of climate crisis due to human intervention in environment. Their effects on health have alarmed global scientific community. Among them, autoimmune diseases, a heterogeneous group disorders, increased dramatically many parts world, likely result changes our exposure factors. However, only limited number studies attempted discover analyze complex association between diseases. This narrative review has therefore tried fill this gap. First all, activation pathways autoimmunity after been analyzed. It also shown wildfires, desert dust storms eruptions may damage induce responses inhaled PM2.5, mainly through oxidative stress pathways, pro-inflammatory cytokines epithelial barrier damage. In addition, it heat stress, addition increasing cytokines, disrupt intestinal barrier, thereby its permeability toxins pathogens or inducing epigenetic changes. toxic elements accelerate progressive destruction myelin, which potentially trigger multiple sclerosis. The diverse mechanisms by vector-borne, water-, food-, rodent-borne diseases often follow described. post-disaster onset worsening disease demonstrated. Given all above, rapid restoration services mitigate flare-up conditions is critical.
