Approximately 64% of the Republic Korea comprises mountainous areas, which as cold and high-altitude regions are gravely affected by climate change. Within alpine-subalpine ecosystems, microbial communities play a pivotal role in biogeochemical cycling partly regulate change through such cycles. We investigated composition function communities, with focus on fungal Korea’s second tallest mountain, Mt. Jiri, along four-point-altitude gradient: 600-, 1,000-, 1,200-, 1,400-m. Soil pH elevation were negatively correlated, soils becoming more acidic at higher altitude. Of five soil enzyme activities analyzed, cellobiohydrolase, β-1,4-glucosidase, β-1,4-xylosidase activity showed differences among levels, lower 600 m than that 1,400 m. biomass correlated positively increasing water content. The decrease β-1,4-N-acetylglucosaminidase suggests reduction altitude, while factors other may influence increase β-1,4-glucosidase β-1,4-xylosidase. Fungal alpha diversity did not exhibit an elevational trend, whereas beta formed two clusters (600–1,000 1,200–1,400 m). Community was similar elevations, Basidiomycota being most predominant phylum, followed Ascomycota . Conversely, 1,000 m, dominant, possibly due to increased pathotroph percentage. Elevational gradients induce changes properties, vegetation, temperature precipitation, all impact altogether create mutually reinforcing system. Hence, inspection elevation-based can aid inferring ecosystem specifically those related nutrient cycling, help assess oncoming direct indirect effects

However, specific changes and underlying mechanisms by natural that influence multifunctionality karst remain poorly understood. In this study, soil, litter, fine root samples were collected from four chronosequence stages vegetation restoration—grassland (G), shrubland (SH), shrub-tree land (ST), forest (F)—within ecosystem Southwestern China. The aim was to evaluate impacts on using an averaging approach. results demonstrated indices C-cycling functionality, N-cycling P-cycling total increased progressed, along with plant diversity. structure plant, bacterial, fungal communities varied across different restoration, exhibiting highest microbial diversity SH stage. Additionally, tightness complexity co-occurrence networks bacteria fungi advancing higher positive links observed than bacteria. functional significantly positively correlated increasing diversity, litter nutrient contents, biomass, community, enzyme activities, soil contents but not bacterial diversities. Furthermore, Random Forest model revealed plants exerted greater compared other factors. It is plausible community networks, levels through input nutrients rather altering enhance multifunctionality.

The abiotic environment exerts strong effects on plant‐associated microbes, shaping their interactions with plants and resulting ecosystem processes. However, these plant–microbe are often highly specific contingent the driver or microbial group, requiring synthesis work describing general patterns from this generate hypotheses guide mechanistic work. To address this, we conducted a meta‐analysis of climate change‐related factors, namely warming, drought, eCO 2 , microbes distinguishing by taxonomic biological group (bacteria, fungi virus) plant part where found associated (phyllosphere rhizosphere). We driver‐specific patterns, whereby drought significantly reduced abundance, whereas warming had no significant effects. In addition, were being negatively affected but positively (eCO enrichment effect), bacteria viruses not any factor. Likewise, rhizospheric phyllospheric Collectively, findings point to important implications for global change research highlighting contrasting drivers contingency such microbe life histories nature plants.

Zingiberaceous plants are versatile and find application in various fields, including food, medicine, cosmetics. Recently, turmeric other have become readily available through online platforms. However, the quality, specifically curcuminoid content, has not been adequately assessed. In light of this issue, study is aimed at analyzing contents, bisdemethoxycurcumin, demethoxycurcumin, curcumin, using high‐performance liquid chromatography. The analysis targets rhizomes Zingiber montanum (ZM), Curcuma aromatica (CA), wanenlueanga (CW), zedoaria (CZ), sixteen longa (CL) samples sold on influence species cultivation locations was evaluated, compared, clustered. results indicated that CL exhibited highest followed by CA, CZ, ZM, CW, respectively. Curcumin detected while bisdemethoxycurcumin demethoxycurcumin were absent ZM. Cluster revealed CW closely related to CA either cluster. Among samples, most commonly found curcuminoids Three contained contents less than 5%, failing meet standard level specified Thai Herbal Pharmacopoeia. Furthermore, ten had total higher 10%, with three exceeding 15%. top from different as follows: Tha Yang District, Phetchaburi Province (17.02%); Phop Phra Tak (16.97%); Pak Tho Ratchaburi (15.45%). could be grouped into two major categories: low high groups. This offers valuable insights for consumers seeking high‐quality curcuminoids, By focusing can make informed decisions when purchasing online. information only aids selecting superior quality but also enhances overall consumer experience ensuring potency efficacy purchased products.

In the context of present climate change concerns, quantification forest biomass and comprehension carbon stock distribution within protected areas are paramount importance for exact budgeting development effective management strategies. This study conducted comprehensive field assessments with primary objective quantifying tree stocks, as well assessing structural attributes stands. These involved meticulous collection ground-based data encompassing various attributes, including circumference at breast height (CBH), stem height, basal area, density, frequency, girth class by utilizing a simple random sampling methodology.

Mountain regions play a crucial role in maintaining global biodiversity, with altitude exerting significant influence on soil microbial diversity by altering plant diversity, nutrients, and microclimate. However, differences community composition between topsoil (0–10 cm deep) subsoil (10–20 remain poorly understood. Here, we aimed to assess network complexity, assembly the layers of dry–hot Jinsha River valley southwestern China. Using high-throughput sequencing samples collected along an altitudinal gradient, found that bacterial decreased increasing altitude, while showed no altitude-dependent changes. Fungal also varied fungal change. These findings suggest was more sensitive changes than subsoil. Bacterial tended be governed stochastic processes, deterministic. Soil complexity enhanced but reduced as increased. Interestingly, presence woody species negatively affected both layers. pH water content composition, organic carbon total nitrogen positively influenced composition. Simultaneously, herb mainly subsoil, respectively, nutrients had effect diversity. directly indirectly affects topsoil, subsequently influencing through nutrient availability.
