Moso bamboo (Phyllostachys edulis) is a fast-growing species that commonly invades neighboring broadleaf forests and has been widely reported in subtropical forest ecosystems. However, little known about the effect on soil phosphorus (P) bioavailability its potential influence factor during moso expansion. Here, four P bioavailable fractions (i.e., CaCl2-P, Citrate-P, Enzyme-P, HCl-P), acid phosphatase activity, iron aluminum oxides (Fed Ald), total pool at depths of 0-10 cm, 10-20 20-40 cm were measured three expanding interfaces (a forest, mixed bamboo-broadleaf pure forest) southern China. Regardless depths, CaCl2-P content was significantly lower than other two types, HCl-P Enzyme-P activity notably but Citrate-P did not differ among stands. Moreover, enhanced compared to depths. The redundancy analysis showed pH plays an important role regulating These findings indicate invasion into altered storage capacity, which implications for understanding cycle expansion regions.

Microbial network complexity is an important indicator for assessing the effectiveness of vegetation restoration. However, response microbial bacteria and fungi to different restoration types unclear. Therefore, in this study, we selected four ( Pinus sylvestris var. mongholica , Larix principis- rupprechtii Populus tomentosa Ulmus pumila ), while nature grassland as a control, Zhangjiakou Tunken Forest Farm, which typical agricultural pastoral ecotone northern China, investigate soil diversity types. Our result showed that bacterial Shannon Chao indices P. were significantly 7.77 22.39% higher than those 20–40 cm layer, respectively. The fungal U. 85.70 146.86% 40–60 Compared natural grassland, networks became more complex plantation forests L. ). increased with carbon nitrogen. suitable planting Zhangjiakou, because its high carbon, nitrogen complexity. Bacterial community composition was found be closely related organic (SOC), total (TN), SOC, clay silt content. This improvement enhances ecological service function ecotone.

Moso bamboo (Phyllostachys edulis) is a crucial species among the 500 varieties of found in China and plays an important role providing ecosystem services. However, remote sensing studies on invasion bamboo, especially its impact forest biodiversity, are limited. Therefore, we explored feasibility using Sentinel-2 multispectral data digital elevation from Shuttle Radar Topography Mission random (RF) algorithms to monitor changes diversity due spread bamboo. From October November 2019, researchers conducted field surveys 100 subtropical plots Zhejiang Province, China. Four biodiversity indices (Margalef, Shannon, Simpson, Pielou) were calculated survey data. Subsequently, after completing epochs training testing, developed RF prediction model assessed performance three key metrics: coefficient determination, root mean squared error, absolute error. Our results showed that has strong predictive ability for all except Pilou index, which average ability. These demonstrate caused by spreading

Amid global environmental concerns, the issue of bamboo expansion has garnered significant attention due to its extensive and profound impacts on ecosystems. Bamboo occurs in native introduced habitats worldwide, particularly Asia. However, effects soil pH, nutrient levels, microbial communities are complex vary across different environments. To address this knowledge gap, we conducted a meta-analysis with 2037 paired observations from 81 studies. The results showed that pH increased by 6.99 % (0-20 cm) 4.49 (20-40 after expansion. Notably, more coniferous forest than broadleaf forest. Soil progressively over time since establishment stands. extent elevation was significantly positively correlated proportion within stand mean annual solar radiation. In contrast, it negatively temperature. is closely related stage expanded type rather primarily shaped climatic factors large scale. We also found into forests brought about notable 14.14 reduction total nitrogen (TN). Varied stages resulted TN reductions 6.88 7.99 for mixed stands, respectively, compared forests.

Taken together, our findings highlight leads an alters N components communities, providing valuable insights future ecological conservation resource management.

Soil quality is closely related to the evolution of forest ecosystems, especially in context global warming; therefore, it essential study changes soil caused by invasion moso bamboo its habitat. In this study, we selected plantation forests and natural secondary with typical vegetation northern subtropics, Quercus acutissima (QAP) oak (OSF), collected plant community physicochemical data, established a index (SQI) assess how affects quality. addition, mechanisms driving effects on were investigated using partial least squares structural equation model (PLS-SEM). The results demonstrated that: (1) Moso significantly affected structure properties, there inconsistent indicators different origins, general expansion properties concentrated topsoil (0–20 cm). (2) bulk density (BD), total porosity (TSP), nitrogen (TN), available potassium (AK) comprised minimum data set (MDS) used calculate SQI, SQI origins ranged from 0.48 1, led significant decrease surface layer QAP.

Moso bamboo (Phyllostachys edulis (Carrière) J. Houz.) forests are a vital forest type in subtropical China. This study investigates the diversity, floristic composition, and phylogenetic structure of understory vegetation these within evergreen broad-leaved eastern Using grid-based sampling, we calculated species diversity indices, employed correlation analysis, redundancy structural equation modeling to assess effects canopy closure, soil properties, topography. The exhibited high richness, with shrub layer demonstrating phytogeographic characteristics predominantly associated tropical distribution types, while herbaceous is characterized by temperate types. Canopy closure environmental factors significantly influenced showing clustered (NTI > 0, NRI 0) negative diversity. In contrast, herb displayed divergent < 0), shaped neutral stochastic processes, reflecting endemic taxa interspecific interactions. These findings emphasize need for targeted management practices conserve biodiversity, focusing on enhancing protecting their ecological

Salt-tolerant plants (STPs) play an important role in saline-alkali soil remediation, but their interaction with microorganisms remain incompletely elucidated. This study explored the effects on microbial community structure, function, and quality land of four treatments: no plant (CK), Triticum aestivum L. (TA), Tamarix chinensis Lour. (TC), Hibiscus moscheutos Linn. (HM). The results indicated that planting TC, TA, HM effectively reduced electrical conductivity (EC) by 82.9, 88.3, 86.2%, respectively. TC TA significantly decreased pH from 8.79 to 8.35 8.06, respectively, (p < 0.05). Moreover, nutrient content enzymatic activities were enhanced. Notably, exhibited most significant improvement.
