“…A 7-year field experiment was conducted in a subtropical moso bamboo (P. edulis) plantation in Zhejiang Province, China to examine the effects of varying N addition rates (0, 30, 60, and 90 kg N ha −1 year −1 ) on soil respiration rates with stumps of three ages (1, 3, and 5 years after cutting). Results indicated that N addition reduced soil respiration by 4.69 to 27.37% compared to the control treatment (Cai et al, 2021;Li et al, 2022). Nitrogen dynamics under the direct influence of trees with and without BNI capacity.…”

Nitrogen (N) is an important component of the forest soils and plays a pivotal role in the ecosystem’s health, also in broadleaf and Moso bamboo (Phyllostachys edulis) forests. Nitrogen plays numerous functions in the production and transformation of soil organic matter (SOM) and alterations in the soil’s physicochemical and biological properties. Despite the extensive research on soil properties and microorganism diversity in broadleaf and Moso bamboo forests, we still know very little about N dynamics and its significance in broadleaf and Moso bamboo forests, or how various physical and environmental variables influence soil physicochemical, N dynamics, and biological attributes. This article provides a thorough overview of the role of N dynamics in broadleaf and Moso bamboo forests and changes in soil physicochemical properties processes by summarizing recent advances in our knowledge of forest soil microbial diversity, and carbon (C) and N sink in broadleaf and Moso bamboo forests. As broadleaf and Moso bamboo forests are very sensitive to little change, even a small change in these ecosystems can alter the overall N dynamics. Here, we dissect the soil ecology of broadleaf and Moso bamboo forests to provide insights into the possibilities and consequences of future studies of N dynamics in these ecosystems.

IntroductionAlthough numerous studies have investigated ecosystem-scale soil respiration (SR) at different ecosystem, our understanding of spatial heterogeneity of SR at plot scale is still incomplete, especially in tropical rainforests with complex topography. Further, the ecological factors that drive the variability of SR in tropical rainforests is also poorly understood.MethodsHere, we investigated the spatial variations and control mechanisms of SR in a 60-ha plot of old-growth tropical rainforest with complex topography. Specifically, we sampled a 60-ha plot in intervals of 20 m to measure SR with LI-8100, used semi-variogram of geostatistical tools to examine spatial heterogeneity of SR.ResultsThe mean SR rate in this plot was 4.312 ± 0.0410 (SE) μmol m−2 s−1. Geostatistical analysis indicated that the SR rate at this plot had a moderate spatial dependence, with a nugget-to-sill ratio of 68.1%. The coefficients variance of SR was 36.2% and the patch size was approximately 112 m. Stepwise linear regression analysis (involving a multiple regression tree) revealed that the independent factors regulated different types of SR’s. Liner mix-effect models showed that SR was significantly positively related to soil phosphorus and negatively to the slope in the 60-ha plot. Spatial disturbance of SR along multidimensional habitats that an increase in elevation of the multidimensional habitat, which was accompanied by enhanced SOC and soil phosphorous, also increased its SR in the 60-ha plot.DiscussionThis study would be helpful in designing future field experiments for a better understanding of SR at plot scale.

“…Furthermore, the stumps not only occupy great amounts of land and severely hinder the elongation of the rhizome system of Moso bamboo forests, but are also extremely unfavorable towards the growth of bamboo shoots, greatly decreasing their yield and hindering their sustainable management [6]. Bamboo stumps can provide habitats and abundant organic nutrients for decomposers, which are crucial forest carbon pool resources [7]. In addition, the decomposition products of bamboo roots and stems are essential in the soil environment of Moso bamboo woodland and the ecosystem of Moso bamboo forests in terms of material transformation and nutrient cycling [6].…”

Background and Objectives: Fungi degrade lignin and other fibers, thus playing an essential role in the decomposition of Phyllostachys edulis (Carrière) J.Houz. (Moso bamboo) stumps. Herein, we characterized key soil fungal communities near different levels of decomposing Moso bamboo stumps (mildly, moderately, and heavily decayed). Materials and Methods: High-throughput sequencing technology was used to analyze the soil fungal communities inside and outside of mild, moderate, and heavy decomposing Moso bamboo stumps. Results: We found nine phyla, 30 classes, 77 orders, 149 families, and 247 genera of soil fungi near the bamboo stumps. Soil fungi OTUs and diversity and richness indices were lower outside than inside the stumps, and decreased with increasing degrees of decay. Inside the bamboo stumps, Soil fungi OTUs and diversity and richness indices were the highest and lowest in moderate and heavy decay bamboo stumps, respectively. Ascomycota dominated inside (from 81% to 46%) and outside (from 69% to 49%) the stumps, and their relative abundance gradually decreased with decomposition, whereas that of Basidiomycota increased outside the stumps (from 17% to 49%). Two-way ANOVA showed that the interaction between the two factors of occurring inside and outside the bamboo stumps and the degree of decay, significantly affected Chytridiomycota and Penicillium (p < 0.001) and significantly affected Mucoromycota (p < 0.05). The abundance of different genera was significantly correlated with saprotrophic functional groups. Conclusion: Changes in the structure and functional groups of soil fungal communities may play an important role during different levels of decomposition of Moso bamboo stumps. This study provides a scientific basis for screening functional fungal strains that promote the decomposition of Moso bamboo stumps.
