Abstract ：
Background and AimsAge-related alterations in nitrogen (N) acquisition by canopy trees has been extensively explored; however, little is known regarding N uptake strategy of coexisting plant species during forest plantation development. MethodsA field experiment was conducted to evaluate plant N uptake in subtropical Cunninghamia lanceolata plantations of varying ages (7, 15, 24, and 34 years). Using a hydroponic method, we assessed the root capacity to uptake NH4+, NO3-, and glycine by the coexisting tree (C. lanceolata), a shrub (Ficus hirta), and a herb (Pteris semipinnata). ResultsBoth the canopy and understory vegetation preferred NH4+ as a N source in hydroponic culture, followed by glycine and then NO3- . Root N uptake rates with increasing plantation age varied by plant species and N source. For F. hirta, the NO3- uptake rate increased from 0.38 to 0.78 mu g N.g(-1) root.h(-1), while it decreased from 1.64 to 0.30 mu g N.g(-1) root.h(-1) for P. semipinnata as the C. lanceolata plantation developed. No clear pattern was observed for C. lanceolata. A positive relationship between root AM colonization rate and NO3- uptake rate was observed for F. hirta, but not for C. lanceolata and P. semipinnata. The contribution of glycine to P. semipinnata total N uptake increased progressively with plantation age. ConclusionOur results indicate that N acquisition among coexisting tree and understory vegetation varied with plant species and N form in hydroponic culture. Notably, understory plants exhibited greater flexibility in N acquisition than overstory trees during the development of subtropical C. lanceolata plantations.

Abstract ：
Insect foliar herbivory is ubiquitous in terrestrial ecosystems, yet its impacts on soil nitrogen cycling processes remain not yet well known. To examine the impacts of insect foliar herbivory on soil N2O emission flux and available nitrogen (N), we conducted a pot experiment to measure soil available N content and soil N2O emission flux among three treatments (i.e., leaf herbivory, artificial defoliation, and control,) in two broad-leaved trees (Cinnamomum camphora and Liquidambar formosana) and two conifer trees (Pinus massonianna and Cryptomeria fortunei). Our results showed that insect foliar herbivory significantly increased soil inorganic N (i.e., NH4+-N and NO3--N), dissolved organic nitrogen (DON) and microbial biomass nitrogen (MBN) contents, and urease activity compared to control treatment. However, there were no differences in soil available N contents and urease activity between artificial defoliation and control treatments, implying that insect foliar herbivory had greater impacts on soil available N contents compared to physical damage of leaves. Moreover, soil N2O emission fluxes were increased by insect foliar herbivory in Cinnamomum camphora and Pinus massonianna, but not for the other two tree species, indicating various effect of insect foliar herbivory on soil N2O emission among tree species. Furthermore, our results showed the positive correlations between soil N2O emission flux and soil NO3--N, DON, MBN, and acid protease activity, and soil inorganic N, pH, and MBN mainly explained soil N2O emission. Our results implied that insect foliar herbivory can speed up soil nitrogen availability in subtropical forests, but the impacts on soil N2O emission are related to tree species.

Abstract ：
为探究低强度计划火烧后亚热带森林土壤细菌群落的恢复特征及其对火烧黑炭输入的响应，本研究以亚热带马尾松人工林火烧迹地为对象，设置不同火后黑炭输入量处理(移除C0、单倍C1和双倍C2)和未火烧对照(UB),分别于火后1年和5年采集0～10 cm土壤样品，利用高通量测序技术分析土壤细菌群落多样性和结构特征，并结合土壤因子探讨其调控机制。结果发现，计划火烧和黑炭处理对土壤细菌群落多样性无显著影响(P>0.05)。与火后1年相比，火后5年土壤细菌群落扩增子序列变体(ASV)数目和Chao1指数显著降低(P<0.01),Shannon指数显著增加(P<0.05)。基于Bray-Curtis距离的NMDS分析表明，火后1年土壤移除黑炭土壤细菌群落结构与对照土壤差异显著(P<0.05),而火烧5年后不同处理之间土壤细菌群落结构相似(P>0.05)。土壤pH是土壤细菌群落结构的关键调控因子，分别能解释火后1年和5年土壤细菌群落结构变化的46.3%和50.5%。酸杆菌门、变形菌门、放线菌门和绿弯菌门是土壤中的优势细菌类群。与火后1年土壤相比，火后5年土壤变形菌门和放线菌门相对多度显著降低，C0和C1土壤厚壁菌门细菌相对多度显著增加(P<0.05)。C1土壤芽单胞菌门相对多度显著高于UB土壤；火后5年，C0和C1土壤厚壁菌门相对多度显著高于对照UB土壤，C0土壤厚壁菌门相对多度显著高于C2土壤(P<0.05)。综上，亚热带森林土壤细菌群落多样性和结构能在低强度火后短期内恢复到未火烧水平，火烧黑炭对土壤细菌类群相对多度具有长期调控效应，未来应结合土壤养分循环等生态功能持续关注亚热带森林火后土壤关键细菌类群的动态变化。

植食性昆虫食叶是森林生态系统普遍存在的现象.为了解有关亚热带常绿阔叶林不同植物叶形态和养分性状对叶虫食特征种间差异的影响，以亚热带细柄阿丁枫天然林为研究对象，比较20种优势植物叶虫食率和虫食频度的种间差异，并分析叶片性状与叶虫食特征的关系.结果发现，亚热带常绿阔叶林20种优势植物的叶虫食率（4.3%-24.2%）和总虫食频度（13%-93%）存在显著的种间差异性，且以轻度、中度叶片虫食为主.不同植物的叶表观性状和养分含量性状亦存在显著的种间差异.相关性分析发现，叶面积、鲜重、干重和叶钾含量与叶片总虫食率、总虫食频度、中度虫食频度和重度虫食频度均呈显著正相关性，而与轻度虫食频度相关性不显著；叶钠含量与叶总虫食频度、中度虫食频度存在显著负相关性.逐步多元回归分析发现，叶面积、叶钾含量和钠含量是解释叶总虫食频度的关键因子，而叶钾含量和叶面积是解释叶虫食率的关键因子，分别解释虫食频度和虫食率变异的63%和46%.本研究表明亚热带天然林不同植物叶虫食特征存在种间差异，与植物叶片形态和养分性状的种间差异性密切有关.（图4表3参34）

Abstract ：
Global change factors like atmospheric nitrogen (N) deposition and drought pose threats to forest ecosystem including soil microbial diversity. However, how arbuscular mycorrhizal (AM) fungi associated with tree respond to N deposition and drought remains largely unknown. Here root- and soil-inhabiting AM fungi were examined in a field experiment involving N addition and simulated drought (precipitation exclusion) in a Chinese fir (Cunninghamia lanceolata) plantation. The results showed that precipitation exclusion significantly reduced AM fungal intraradical colonization rate in summer, while N addition had no significant effect on AM fungal morphological traits of intraradical colonization rate, hyphal and spore densities. However, seasonal changes significantly affected AM fungal morphological traits, with higher values were observed in summer than in winter. Neither N addition nor drought significantly affected AM fungal diversity or community composition, but AM fungal communities exhibited pronounced seasonal differences. In winter, both root- and soil-associated AM fungal community composition significantly correlated with the ratio of microbial biomass carbon and phosphorus (MBC/MBP), while in summer AM fungal communities were primarily associated with MBP and DOC. These findings highlight the importance of accounting for interaction of N addition and drought, and seasonal response difference on AM fungi in subtropical forest ecosystems.

Abstract ：
Ongoing climate change has increased the frequency and intensity of climate extremes such as heatwaves, impacting terrestrial ecosystems. Grasslands are often shaped by human activities such as mowing, which may modulate their responses to climate extremes. However, the mechanisms underlying such responses and the factors important in stabilizing grassland functioning under environmental disturbance are currently poorly understood.In this study, we experimentally compared the effects of heatwaves and mowing on the functioning (based on CO2 exchange) of two different grassland types, Stipa krylovii typical grassland (Sti-Tpl) and Leymus chinensis meadow steppe (Ley-Mdw), in Inner Mongolia. In each grassland, ecosystem CO2 fluxes and plant community characteristics (biomass, community structure and biodiversity indices) were recorded. We specifically focused on the stability of grassland CO2 exchange during heatwave events (resistance), the capacity to regain functionality afterwards (recovery) and the plant factors influencing these resilience metrics in both grasslands.The results indicate non-linear temporal trajectories in carbon flux recovery, with a weak correlation between resistance and recovery. Ecosystem respiration (RE) generally exhibited greater resistance and recovery to heatwaves than gross ecosystem production (GEP); GEP reduction led to a decrease in net ecosystem production (NEP). However, local mowing practices partially mitigated these negative effects. The importance value (Iv) of dominant species and biodiversity both positively influenced NEP resistance, but their effects on NEP recovery were opposite, as Iv enhanced recovery while biodiversity reduced it. Finally, the contribution level of dominant species to grassland stability was closely related to their Iv in the plant community.Synthesis. In this study, we investigated the complex factors influencing ecosystem resistance and recovery to heatwaves and mowing in two distinct grasslands. We found that the physiology, morphology and regeneration traits of the dominant species in each grassland community explained most of the divergence of grassland function stability. Thus, to buffer ecosystems against adverse impacts of climate extremes in conjunction with land management, it can be advantageous to focus on the maintenance or selection of dominant species rather than solely on increasing species richness.

Abstract ：
As one of the most durable legacies of fire, charcoal plays a key role in long-term soil carbon (C) storage due to its long residence time. However, few attempts have been made to investigate the impact of naturally deposited charcoal on soil organic C (SOC) stability in fire-affected forests in a long-term field trial. In this study, we used a field-based charcoal manipulation experiment to assess the input of charcoal on post-fire SOC stability in a subtropical plantation forest. The experimental design included four treatments: removal of all visible charcoal (C0), charcoal retained in-situ (C1), addition of charcoal removed from C0 plots to separate plots (C2), and an unburnt control (UB). Seven years after treatment implementation, soil samples were collected from 0 to 10 and 10-20 cm depth to measure soil organic C fractions, microbial biomass C (MBC), C pool management index (CPMI), aggregate stability and the distribution of organic C within aggregate size classes. Our results showed that charcoal had no significant effect on dissolved organic C (DOC) at either depth. However, charcoal significantly influenced MBC, CPMI, and the distribution of SOC in small aggregate fractions (<0.05 mm) in a depth-dependent manner. At the 0-10 cm depth, CPMI and the allocation of SOC to small aggregates were significantly higher in C2 and UB soils than in C0 (p < 0.05), whereas no differences were observed at the 10-20 cm depth. In contrast, MBC was significantly higher in C2 and UB than in C0 soils only at the 10-20 cm depth (p < 0.05). Despite the persistence of negative effects from the initial burning event, our findings suggest that fire-derived charcoal can enhance SOC stability by promoting microbial assimilation and facilitating SOC allocation to more stable aggregate fractions with longer turnover times. Taken together, these findings suggest that charcoal deposited during fire contributes to soil C stabilization in subtropical forest plantations subjected to broadcast burning.

Abstract ：
Background and aims: Litter input plays important roles in controlling soil aggregation and aggregate carbon (C) content. However, the effects of litter input on soil aggregate C turnover in different forest types remain unclear. Methods: We examined the changes of aggregate mass proportion, and the litter-derived and native C content among soil aggregates after three years of aboveground and root litter input, using C-13 isotope tracing in a natural forest, a Chinese fir (Cunninghamia lanceolate) plantation, and a masson pine (Pinus massoniana) plantation in southeastern China. Results: Belowground root litter rather than aboveground litter input enhanced soil aggregation. Litter input increased total C content across all aggregates, and the effects were no different between aboveground litter and belowground root litter input except for the >2 mm fraction. Belowground root litter input led to less native C content across three forest types. However, belowground root litter input resulted in more formation of litter-derived C than aboveground litter input under masson pine plantations, but not for both natural forest and Chinese fire plantation, suggesting a different effect of litter input on the litter-derived C formation among forest types. In addition, forest type affected soil aggregation and aggregate C turnover, and the differences in litter quantity and litter C:N ratio can explain the changes in soil aggregation and aggregate C turnover among forest types. Conclusion: Our results imply that belowground root litter input plays a more important role in controlling soil aggregation and aggregate C turnover than aboveground litter, and the impact on newly litter-derived C formation depends on forest type.
