In recent years, the cultivation techniques of large-diameter forests have garnered increasing attention due to their significant ecological and economic values. However, effects small-scale latitudinal changes on species distribution community composition trees remain poorly understood. This study aims investigate narrow gradients structure forests. Investigating these impacts provides critical insights for silvicultural selection forest optimization, particularly in context global warming, is essential sustainable development this study, three communities along a gradient subtropical China were selected by analyzing diversity. The was also studied rank curves, diameter structure, PCoA, MRPP, indicator species. results revealed that as latitude increased, proportion rare rose from 43.8% LL (low-latitude) 63.2% HL (high-latitude) areas, while stem density dominant number stems per increased. Additionally, homogeneity decreased (based PCoA MRPP analysis), age-class structures became more complex, tropical genera gradually declined, whereas temperate These findings indicate variation key driver Currently, northern Guangdong region suitable development, with Fagaceae (particularly Castanopsis Lithocarpus) showing high potential. Specifically, eyrei, fissa, Ternstroemia gymnanthera are well-suited stand Guangdong. For mixed forests, Machilus chinensis, Cinnamomum porrectum, Schima superba recommended optimal associated warming progresses, suitability tree afforestation may shift, necessitating adaptive management strategies.

This study investigates the structure of soil bacterial communities in brown mountain soils beneath deciduous broadleaf forests Dongling Mountain and their response to physicochemical properties. Aiming provide a scientific basis for conservation sustainable forest development under forests, this research utilized high-throughput sequencing technology examine diversity community bacteria different tree species, alongside assessing The results revealed significant differences nutrient content between 0–20 cm 20–40 layers. Additionally, N:P was found be below national average, indicating potential nitrogen limitation. Dominant phylum included Actinobacteria, Proteobacteria, Acidobacteria. also that similar species at same depth but varied significantly with depth. Furthermore, redundancy analysis (RDA) showed available potassium (AK), total (TN), ammonium (NH4+-N) influenced structural changes community. highlights characteristics its relationship properties, offering valuable insights regional ecosystem management.

N deposition is a key factor affecting the composition and function of soil microbial communities in wetland ecosystems. Previous studies mainly focused on effects during growing season (summer autumn). Here, we response community structure winter. Soil from Sanjiang Plain wetland, China, that had been treated for past 11 years by using artificial at three levels (no intervention N0, with 4 g m−2 yr−1 N1, 8 N2). characteristics were determined bacterial was characterized high-throughput sequence technology. The significantly reduced diversity detected winter compared control it changed community. At phylum level, high (N2) increased relative abundance Acidobacteria decreased Myxococcota Gemmatimonadota N0. In N2, general Candidatus_Solibacter Bryobacter pH, organic carbon (SOC), total nitrogen (TN) factors pH correlated cycling, probably due to its significant correlation aerobic_chemoheterotrophy. results show long-term reduces nutrients wetlands decreases diversity, resulting negative impact plain wetland.

The colonization of alien plants in new habitats is typically facilitated by microorganisms present the soil environment. However, diversity and structure archaeal, bacterial, fungal communities latitudinal spread remain unclear. In this study, rhizosphere bulk Chromolaena odorata were collected from five latitudes Pu' er city, Yunnan Province, followed amplicon sequencing communities. Alpha beta results revealed that richness indices structures significantly differed along gradient. Additionally, significant differences observed bacterial Shannon index, as well between soils. Due to small spatial scale, trends variation not pronounced. Total potassium, total phosphorus, available nitrogen, potassium nitrogen important driving factors affecting microbial community structure. Compared with those soil, co-occurrence networks presented lower complexity but greater modularity positive connections. Among main functional fungi, arbuscular mycorrhizae saprotrophs more abundant soil. microbes soils further underscore impact C. invasion on environments. microbiota gradients, specific factors, demonstrate distinct nutrient preferences among archaea, bacteria, fungi indicate complex responses elements following odorata.

Tree-microbe interactions are essential for forest ecosystem functioning. Most plant–microbe research has focused on the rhizosphere, while composition of microbial communities in phyllosphere remains underexplored. Here, we use 16S rRNA gene sequencing to explore differences between beech and Scots pine phyllospheric microbiomes at European continental scale, map their functional profiles, elucidate role host trees, features, environmental factors such as climate atmospheric deposition microbiota assembly. We identified tree species associated foliar trait (specifically carbon:nitrogen ratio) primary drivers bacterial communities. characterized taxonomical epiphytic bacteria across an gradient from Fennoscandia Mediterranean area, with major changes temperature nitrogen deposition. also showed that played a crucial affecting assembly both species. This study contributes advancing our understanding shaping highlighting need broad-scale comparative studies (covering wide range traits conditions) how mediates responses global change. Phyllosphere scale is influenced by traits, well deposition, according analyses leaf microbes.

Intercropping is a commonly employed agricultural technique that offers numerous advantages, such as increasing land productivity, enhancing soil health, and controlling soil-borne pathogens. In this study, Artemisia argyi, Dioscorea esculenta, Arachis pintoi were intercropped with coconuts compared naturally growing weeds (Bidens pilosa), respectively. The regulatory mechanism of intercropping was examined by analyzing the variability in properties microbial community structure across different modes depths (0–20 cm, 20–40 40–60 cm). results indicate can increase diversity bacteria fungi. Moreover, depth increases, changes communities weaken. reduced SOM increased pH, which directly related to abundance Acidobacteria soil. various systems, disparities resulting from A. are particularly pronounced. Specifically, leads an potassium phosphorus levels, well enhancement Bacillus sp., plays crucial role suppression plant pathogenic fungi within ecosystem. correlation analysis structural equation modeling (SEM) suggest impacts three systems on composition indicators exhibit considerable variation.
