ABSTRACT Arbuscular mycorrhizal fungi (AMF, phylum Glomeromycota) are essential to plant community diversity and ecosystem functioning. However, increasing human land use represents a major threat native AMF globally. Characterizing the loss of remains challenging because many taxa undescribed, resulting in poor documentation their biogeography family‐level disturbance sensitivity. We survey sites representing human‐altered ecosystems across American continents—in Alaska, Kansas, Brazil—to shed light on these gaps. Using recently developed pipeline for phylogenetic placement eDNA, we find evidence three putative novel clades within Glomeromycota, sister Entrophosporaceae , Glomeraceae Archaeosporaceae with geographic structuring. further that Diversisporaceae relatively high families overrepresented more diverse temperate samples. By contrast, cannot be placed into family is higher tropical samples, suggesting harbor undescribed diversity. Moreover, tolerant, while sensitive disturbance. These results underscore vast highlighting way forward systematically improve our understanding response

The degradation of alpine meadows on the Qinghai–Tibet Plateau is a major issue affecting both ecology and economy. Microorganisms play an important role in soil nutrient cycling regulation ecosystem function. This study aimed to investigate species composition diversity microbial communities understand response changes physicochemical properties resulting from meadow degradation. In this study, bacterial fungal communities’ gradient were sequenced by high-throughput sequencing. During process grassland degradation, there 59 taxa 29 showing significant differences. relative abundance pathogenic fungi significantly increased (p < 0.05). PICRUSt2 analysis showed decrease synthesis-related functional gene increase metabolism-related abundance. FUNGuild that symbiotic saprophytic decreased was mainly influenced beta communities. Grassland affects structure, thereby content. work reveals their impact cycling, providing theoretical support for protection sustainable development meadows.

Abstract Our aim was to assess the physical and biochemical properties of soil, chemodiversity dissolved soil organic matter (SOM), arbuscular mycorrhizal fungi (AMF) community associated with Ocotea porosa forests in Brazilian Atlantic Forest biome. We evaluated (i) using standard protocols, (ii) SOM its optical characterization via Fourier‐transform ion cyclotron resonance mass spectrometry, (iii) AMF structure root colonization through morphological characterization. The highest values for Ca 2+ , Mg SOM, S, P, K + Zn geometric mean diameter, weighted average microbial C biomass, respiration, total glomalin, colonization, oxalic malic acids, carbohydrates, lipids, proteins/amino sugars, biological index, fluorescence index were observed preserved plots. also found differences land conservation status: Acaulosporaceae Gigasporaceae strongly correlated Claroideoglomus claroideum Funneliformis mosseae Rhizophagus intraradices more prevalent degraded This has potential increase sequestration, mitigate climate change, contribute preservation an endangered, century‐old tree species

ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also case for soils, but no study to date provided an overall synthesis of current state knowledge. Here we fill this gap with a first global analysis published research on cryptogams, microorganisms, and fauna soils above treeline, structured Based corpus almost 1400 publications expertise 37 soil scientists worldwide, summarise what known about distribution patterns each these organismal groups, specifically along elevation, provide overview available knowledge drivers explaining their changes. In particular, document elevation‐dependent decrease faunal while cryptogams there initial increase followed by towards nival belt. Thus, our data confirm key role that elevation plays shaping biodiversity organisms soils. The response prokaryote turn, was more diverse, whereas fungal appeared be substantially influenced plants.

Despite substantial research on how environmental factors affect fungal diversity, the mechanisms shaping regional-scale diversity patterns remain poorly understood. This study employed ITS high-throughput sequencing to evaluate soil community composition, and co-occurrence networks across alpine meadows, desert steppes, shrublands in southwestern Tibetan Plateau. We found significantly higher α-diversity meadows steppes than shrublands. Random forest CAP analyses identified mean annual temperature (MAT) normalized difference vegetation index (NDVI) as major ecological drivers. Mantel tests revealed that physicochemical properties explained more variation climate, indicating an indirect climatic influence via characteristics. Distance–decay relationships suggested heterogeneity species interactions drive isolation. Structural equation modeling confirmed MAT NDVI regulate pH carbon/nitrogen availability, thereby influencing richness. The highly modular network depended key nodes for connectivity. Vegetation coverage correlated positively with structure, while strongly affected stability. Spatial constrained stability through resource distribution niche segregation, whereas stable concentrated resources among dominant species. These findings enhance our understanding of assemblage processes at a regional scale, providing scientific basis management plateau ecosystems.
