Functional traits reflecting leaf structure and functions can show tradeoff or synergetic patterns. How these patterns exert an ‘afterlife’ effect on litter decomposition, or how such an effect is mediated by soil fauna, remains poorly understood. Here, using litter traits reflecting leaf growth, defence, size and shape, we tested a hypothetical framework addressing (i) the relationships between decomposition rate ( k ) and trait patterns (growth versus defence, chemical versus structural defence and size versus shape) and (ii) how the access of soil macro‐ and mesofauna to the litter alters these relationships. We conducted a litterbag decomposition experiment of 18 tree species in subtropical Hunan, China, for 13 months. Litterbags with mesh sizes of 0.07, 2 and 5 mm were used to mimic the cases of (i) excluding meso‐ and macrofauna, (ii) excluding macrofauna and (iii) including all fauna. For each species, 14 litter traits related to leaf growth and defence and 8 traits related to leaf size and shape were measured. We found a growth‐defence space and a size‐shape space among species: the former was driven by two orthogonal trait gradients reflecting the tradeoffs between mechanical and chemical defences, and between growth and overall defence, respectively; the latter was driven by two orthogonal trait gradients of size and shape, respectively. Among the four gradients, the defence category gradient spanning species with varying relative investments in mechanical versus chemical defences was the only one showing significant relationships with k , mainly due to the significant relationships between mechanical traits and k . The presence of meso‐ and macrofauna significantly increased k but could not significantly change the slope of the relationship between k and any of the trait gradients. Synthesis . We reveal that defence‐related traits predominate over growth‐related or size and shape traits in driving litter decomposition and that soil fauna play a marginal role in modifying such relationships, thereby enhancing our holistic understanding of trait‐decomposition relationships. Our findings indicate that the contribution of relative investments in chemical versus mechanical defence to interspecific variation in leaf litter decomposition deserves broad investigation in different ecosystems.

Food is essential for animal survival, but wildfire can influence the availability and quality of food resources. However, even in fire‐prone regions, we often lack a detailed understanding of how fire alters the nutritional landscape and how plant chemical composition varies over time since fire. In Australian forests, many eucalypts exhibit a key fire adaptation: the ability to resprout epicormically, producing new shoots from aerial stems shortly after fire. Little is known about the nutritional quality of epicormic foliage or how it supports the survival and recovery of endangered arboreal folivores such as the koala ( Phascolarctos cinereus ) and the greater gliders ( Petauroides spp.). This gap in knowledge is particularly urgent to address as wildfires increase in frequency and severity due to anthropogenic climate change. The aim of this study was to measure how the nutrient and plant secondary metabolite (PSM) concentrations of post‐fire epicormic growth changed over 1 year in six eucalypt species known to be browsed by arboreal marsupials. For comparison, we also sampled adult phase foliage from the same species in a nearby unburnt area, and in the burnt landscape where it was available. Total nitrogen concentrations were higher in epicormic foliage than in adult phase foliage from unburnt areas for all six eucalypt species, and declined over time in four of the six species. The available nitrogen concentration (a measure of the concentration of N liberated by mammalian digestion) was only higher in epicormic foliage for four of the six species, also decreasing over time. Concentrations of formylated phloroglucinol compounds, a type of PSM known to deter feeding by marsupial folivores, were generally higher in epicormic foliage. In contrast, unsubstituted B‐ring flavanone concentrations, another class of PSMs, were generally lower in epicormic foliage. Synthesis . This study shows that fire changes the leaf chemistry of a critical food resource for arboreal folivores. This could conceivably influence diet selection and quality after fire by altering trade‐offs between nutrient acquisition and plant defence. This has implications for our understanding of the habitat requirements for threatened folivores, since the tree species normally associated with their diet may differ in quality in burnt and unburnt landscapes.

Tropical forests harbour high taxonomic and phytochemical diversity, with specialised metabolites mediating ecological interactions likely contributing to species coexistence. However, tropical forest loss threatens the existence of many tree species, with a risk of irreversible loss of yet undiscovered phytochemicals. While restoration efforts often target taxonomic recovery, the assembly of phytochemical diversity during restoration remains underexplored. In this study, we characterised the phytochemical diversity of naturally regenerating woody species in a biodiversity enrichment experiment consisting of 52 tree islands varying in area and planted tree diversity, embedded in an industrial oil palm plantation in Sumatra, Indonesia. Using untargeted metabolomics, we characterised phytochemical diversity among 76 regenerating woody species from 34 families occurring 10 years after tree islands establishment. Furthermore, we examined how island area and planted tree diversity influenced phytochemical diversity via stem density and diversity of the regenerating woody species. In addition, we assessed the relationship between chemical dissimilarity (pairwise and of the overall community) and community assembly. We found 27,122 phytochemical features, from which around 40% were alkaloids and terpenoids, while 17% remained unclassified, suggesting the presence of novel metabolites. Phytochemical diversity increased with tree island area, whereas the initial planted tree diversity had no significant effects. The effect of area was mediated by the diversity of regenerated species, whereas stem density had no effect. When accounting for sampling coverage, island area also showed a direct positive effect on phytochemical diversity, suggesting additional area‐associated mechanisms beyond differences in sampling completeness. Community‐level chemical structure showed a weak tendency towards overdispersion, suggesting that species tend to be chemically more dissimilar to their neighbours than expected by chance. Synthesis. Our study shows that establishing tree islands within oil palm plantations can enhance phytochemical diversity through natural regeneration. Larger tree islands support higher species diversity and phytochemical diversity, underscoring the role of area in restoration. These insights are important to advance our understanding of the role of phytochemistry in ecosystem recovery and to guide restoration practices aiming to enhance biodiversity and phytochemical diversity in human‐modified landscapes.

Increasing tree species diversity is known to enhance soil organic carbon (SOC) stocks, but its effect on SOC stability remains a critical uncertainty for climate mitigation. Through examination of a subtropical karst forest diversity gradient in southwest China, we reveal a fundamental shift in SOC stabilization mechanisms using physical fractionation, 13 C nuclear magnetic resonance spectroscopy and metagenomic sequencing. Higher tree species diversity increased total SOC content but paradoxically decreased the ratio of mineral‐associated to particulate organic carbon (MAOC:POC), a key metric traditionally linked to lower stability. This decrease, however, was accompanied by a critical reduction in SOC mineralization rate. Further analysis revealed that this enhanced persistence under high tree species diversity was associated with a trade‐off between stabilization pathways. The role of traditional iron/aluminium oxide‐mediated protection diminished, while two alternative mechanisms strengthened, that is (1) enhanced physical protection of POC through calcium carbonate aggregation, and (2) a profound shift in microbial ecology towards more efficient anabolism. Synthesis. This research demonstrates that tree species diversity actively reconfigures SOC stabilization pathways, emphasizing that ecosystem carbon persistence emerges from a dynamic interplay of physical, microbial and context‐specific mineral controls. These findings suggest that managing for high species richness can enhance both the quantity and the resilience of forest carbon sinks, providing a robust nature‐based solution for climate change mitigation.

Trees associated with arbuscular mycorrhizal (AM) and ectomycorrhizal (EcM) fungi are commonly thought to dominate in nutrient‐rich and nutrient‐poor environments, respectively. However, the mechanisms underlying this pattern remain poorly understood. Here, two potential drivers were evaluated: (i) environmental filtering , where soil fertility shapes tree species dominance by regulating growth and mortality; and (ii) tree‐mediated regulation , where trees modify soil conditions in ways consistent with their mycorrhizal strategy. The importance of these drivers was tested using a comprehensive 15‐year dataset for a 25‐ha temperate forest dynamics plot, including data on individual trees, soil properties, leaf litter production and leaf litter nutrient content. Generalized linear mixed models were employed to estimate the effects of initial soil properties on tree mortality and growth. Leaf litter disposal models and structural equation models were utilized to evaluate the effects of mycorrhizal dominance on changes in soil properties over time. Consistent with the environmental filtering hypothesis, EcM tree mortality increased with soil fertility, while growth declined. However, EcM dominance did not drive soil impoverishment as predicted (i.e. tree‐mediated regulation hypothesis). Instead, EcM dominance was associated with the accumulation of total phosphorus and with reduced losses of available nitrogen and phosphorus over time. Furthermore, leaf litter stoichiometry rather than absolute nutrient levels mediated the effects of EcM dominance on soil physicochemical properties. Synthesis . These results highlight that environmental filtering largely contributes to the distribution of mycorrhizal‐associated trees along a soil fertility gradient. Although tree‐mediated regulation did not directly shape tree distributions, it tended to modify soils in directions opposing their associated niche. This study refines our understanding of plant–soil feedback mechanisms, highlighting that community assembly is primarily governed by local soil conditions, whereas plant‐induced modifications develop more slowly through time.

<h2>1 INTRODUCTION</h2> <p>Water is a major determinant of ecosystem functioning. Alterations in water availability such as those derived from extended dry periods (i.e. drought), structures plant and soil microbial communities as well as their interactions (Pugnaire et al., <span>2019</span>; Van Dyke et al., <span>2022</span>). However, we lack understanding on how above-ground plant traits link to soil microbial communities and the functions they perform in response to drought. An increasing number of studies have shown that subordinate plant species, defined as those that are found frequently in a community but never attain dominance (Mariotte, <span>2014</span>), may have a larger influence on ecosystem functioning than their abundance indicates, especially during drought conditions (Boeken & Shachak, <span>2006</span>; Jia et al., <span>2021</span>; Mariotte, <span>2014</span>; Mariotte, Vandenberghe, Meugnier, et al., <span>2013</span>; Urcelay & Díaz, <span>2003</span>). Dominant and subordinate species generally have different functional traits, associated with rapid acquisition of resources and with resource conservation, respectively (Diaz et al., <span>2004</span>; Grime et al., <span>1997</span>; Mariotte, Vandenberghe, Meugnier, et al., <span>2013</span>). Above-ground, dominants favour biomass production and subordinates favour nutrient retention (Lavorel et al., <span>2011</span>), while below-ground, traits of dominant plant species generally promote bacterial-dominated microbial communities, in contrast to the fungal-dominated communities associated with subordinate plant species (de Vries et al., <span>2012</span>; Grigulis et al., <span>2013</span>). Given the current increase in drought frequency and intensity in many areas of the world (IPCC, <span>2023</span>), assessing mechanisms linking the relative abundance of a species and its contribution to ecosystem functioning in response to drought may enhance our ability to predict ecosystem responses to climate change.</p> <p>Historically, dominant species have been considered more important for ecosystem processes because of the large amount of biomass they produce (‘mass ratio hypothesis’; Grime, <span>1998</span>). However, the biomass of subordinate species often shows higher resistance to drought compared to dominant species (Castillioni et al., <span>2020</span>; Mariotte, <span>2014</span>; Mariotte et al., <span>2015</span>, <span>2017</span>; Mojzes et al., <span>2018</span>).

水是生态系统功能的主要决定因素。水分可用性的变化，如干旱期延长（即干旱）引起的变化，会影响植物和土壤微生物群落的结构及其相互作用（Pugnaire等人，2019；Van Dyke等人，2022）。然而，我们对地上植物性状与土壤微生物群落之间的联系以及它们对干旱的响应功能缺乏了解。越来越多的研究表明，从属植物物种，即那些在群落中频繁出现但从未获得优势地位的植物物种（Mariotte, 2014），对生态系统功能的影响可能比它们的丰度所显示的更大，特别是在干旱条件下（Boeken & Shachak, 2006； Jia等人，2021;Mariotte, 2014; Mariotte, Vandenberghe， Meugnier等人，2013;Urcelay & Díaz, 2003）。优势种和从属种通常具有不同的功能性状，分别与资源的快速获取和资源保护有关（Diaz et al., 2004; Grime et al., 1997; Mariotte, Vandenberghe, Meugnier, et al., 2013）。在地面上，优势植物有利于生物量生产，从属植物有利于养分保留（Lavorel等人，2011），而在地下，优势植物的性状通常促进细菌主导的微生物群落，而与从属植物相关的真菌主导群落形成对比（de Vries等人，2012；Grigulis等人，2013）。鉴于目前世界上许多地区干旱频率和强度的增加（IPCC, 2023），评估将物种相对丰度与其对应对干旱的生态系统功能的贡献联系起来的机制，可能会提高我们预测生态系统对气候变化响应的能力。从历史上看，优势物种被认为对生态系统过程更为重要，因为它们产生大量生物量（“质量比假说”；Grime, 1998）。然而，与优势种相比，从属种的生物量往往表现出更高的抗旱性（Castillioni et al., 2020; Mariotte, 2014; Mariotte et al., 2015,2017; Mojzes et al., 2018）。有研究表明，与微生物群落中的关键分类群类似（Banerjee等人，2018），从属物种可以通过植物-微生物相互作用稳定植物群落中的生态系统功能（“从属保险假说”；Mariotte, 2014）。鉴于植物-土壤微生物相互作用对多个生态系统过程的重要性（Van Der Heijden et al., 2008; Wagg et al., 2014），根-土壤界面对干旱的响应可能对生态系统功能有很大影响。瑞士山地草原的实验证据表明，在干旱期间，从属物种的存在维持了较高的生态系统呼吸速率，这种效应主要是由于土壤真菌的刺激（Mariotte等人，2015;Mariotte, Vandenberghe， Kardol等人，2013）。鉴于土壤微生物群落在土壤有机质（SOM）分解中的重要作用，植物对土壤微生物群落的影响可能对应对气候变化的全球碳(C)和养分循环产生重要影响（Conant et al., 2011; Hursh et al., 2017; Qin et al., 2019）。优势种与从属种对干旱的反应可能不同，因为丛枝菌根真菌（AMF）的定殖可以增加从属种在干旱下的定植，并且它们具有更高的C -氮(N)化学计量灵活性（Mariotte等，2017）。相反，当养分和水分变得有限时，优势物种获得优势的特征（如养分稳态和大生物量形成）可能就不那么有利了（Mariotte et al., 2017）。因此，从属种可能能够利用干旱期间优势种和从属种之间竞争减少所产生的生态位，可能是通过向丛枝菌根合作中投入相对较多的C来获取土壤养分，如N。支持这一点，先前的田间干旱试验表明，在从属种Cynodon dactylon中，菌根丛枝根定植与植株N呈正相关。而优势种雀稗（Paspalum dilatatum）未发现相关性（Mariotte et al., 2017）。此外，丛生菌根共生可以减少从属和优势植物物种之间的竞争（Mariotte, Meugnier, Johnson, et al., 2013），尽管这种作用的方向取决于菌根真菌的类型和环境条件（Lin等，2015；Yao等，2008）。越来越多的证据表明，菌根真菌是植物-植物相互作用的重要调节因子，可以最大限度地减少植物物种之间的适应度差异，调节植物群落动态（Bever等）。

However, we lack understanding on how above-ground plant traits link to soil microbial communities and the functions they perform in response to drought. An increasing number of studies have shown that subordinate plant species, defined as those that are found frequently in a community but never attain dominance (Mariotte, <span>2014</span>), may have a larger influence on ecosystem functioning than their abundance indicates, especially during drought conditions (Boeken & Shachak, <span>2006</span>; Jia et al., <span>2021</span>; Mariotte, <span>2014</span>; Mariotte, Vandenberghe, Meugnier, et al., <span>2013</span>; Urcelay & Díaz, <span>2003</span>). Dominant and subordinate species generally have different functional traits, associated with rapid acquisition of resources and with resource conservation, respectively (Diaz et al., <span>2004</span>; Grime et al., <span>1997</span>; Mariotte, Vandenberghe, Meugnier, et al., <span>2013</span>). Above-ground, dominants favour biomass production and subordinates favour nutrient retention (Lavorel et al., <span>2011</span>), while below-ground, traits of dominant plant species generally promote bacterial-dominated microbial communities, in contrast to the fungal-dominated communities associated with subordinate plant species (de Vries et al., <span>2012</span>; Grigulis et al., <span>2013</span>).

<h2>1 INTRODUCTION</h2> <p>Boreal forests are experiencing unprecedented land-use intensification and shifts in disturbance regimes (Seidl et al., <span>2017</span>; IPCC, <span>2023</span>), which may profoundly impact biodiversity across boreal regions (Gauthier et al., <span>2015</span>). Yet, how these changes affect wood-inhabiting fungal communities remains poorly understood. Wood-inhabiting fungi deliver essential ecosystem functions through deadwood decomposition and nutrient cycling, by forming key interactions with other organisms (Thorn et al., <span>2020</span>), and as indicator species of forest continuity and complexity (Junninen et al., <span>2006</span>; Majdanová et al., <span>2023</span>; Taylor et al., <span>2014</span>). Since wood-inhabiting fungi entirely depend on deadwood for their establishment, growth, and reproduction (Stokland et al., <span>2012</span>), disrupted deadwood continuity could have large consequences for these fungal communities and their diversity (Siitonen, <span>2001</span>). Forest management practices like clear-cutting, shortening rotation periods, and deadwood removal are thought to reduce substrate availability and simplify habitat structure (Abrego et al., <span>2017</span>; Berch et al., <span>2011</span>; Juutilainen et al., <span>2014</span>; Krikken et al., <span>2019</span>). At the same time, changes in fire frequency and severity (Flannigan et al., <span>2009</span>; Remy et al., <span>2023</span>; Seidl et al., <span>2014</span>) could affect the successional window required for some fungal communities to establish. It remains poorly understood how disturbance type (fire versus clear-cutting) and changes in habitat structure through successional time shape wood-inhabiting fungal richness and community composition.</p> <p>Historically, deadwood dynamics in boreal forests, particularly variation in deadwood quantity and quality, are believed to have been shaped by forest fires. These fires produced a large amount of substrate for pioneer wood-inhabiting fungal species through fire-induced tree mortality immediately post-fire (Siitonen, <span>2001</span>). As forests mature, species composition shifts towards late-successional specialist fungi with narrow substrate or microclimatic requirements (Junninen et al., <span>2006</span>). Old-growth boreal forests are believed to serve as key refuges for diverse wood-decaying fungal communities, including specialized and red-listed species, particularly among Agaricomycetes (Penttilä et al., <span>2004</span>; Purhonen et al., <span>2021</span>; Siitonen, <span>2001</span>; Ylisirniö et al., <span>2012</span>). The quantity, quality, and diversity of deadwood that builds up over decades to centuries is believed to be a major factor in the habitat conditions of old-growth forests (Baber et al., <span>2016</span>; Hottola et al., <span>2009</span>; Junninen & Komonen, <span>2011</span>; Lassauce et al., <span>2011</span>; Penttilä et al., <span>2
北方森林正在经历前所未有的土地利用集约化和扰动机制的转变（Seidl et al., 2017； IPCC, 2023），这可能深刻影响北方地区的生物多样性（Gauthier et al., 2015）。然而，这些变化如何影响栖息在木材上的真菌群落仍然知之甚少。栖息在木材中的真菌通过腐木分解和养分循环，与其他生物形成关键的相互作用（Thorn等，2020），并作为森林连续性和复杂性的指示物种（Junninen等，2006;majdanov<e:1>等，2023；Taylor等，2014），发挥重要的生态系统功能。由于栖息在木材中的真菌完全依赖于枯木的建立、生长和繁殖（Stokland等，2012），破坏枯木的连续性可能会对这些真菌群落及其多样性产生重大影响（Siitonen, 2001）。森林管理实践，如砍伐森林、缩短轮作周期和清除枯木，被认为会降低基质的可用性，简化栖息地结构（Abrego等人，2017；Berch等人，2011；Juutilainen等人，2014；Krikken等人，2019）。同时，火灾频率和严重程度的变化（Flannigan et al., 2009; Remy et al., 2023; Seidl et al., 2014）可能会影响一些真菌群落建立所需的演替窗口。干扰类型（火灾与砍伐）和栖息地结构随时间的变化如何影响木材真菌丰富度和群落组成，目前还不清楚。从历史上看，北方森林的枯木动态，特别是枯木数量和质量的变化，被认为是由森林火灾形成的。这些火灾通过火灾引起的树木在火灾后立即死亡，为早期居住在木材上的真菌物种产生了大量的基质（Siitonen, 2001）。随着森林的成熟，物种组成转向具有狭窄基质或小气候要求的晚期演替专业真菌（Junninen et al., 2006）。古老的北方森林被认为是多种木材腐烂真菌群落的关键避难所，包括专门的和红色名录的物种，特别是在真菌中（Penttilä等人，2004；Purhonen等人，2021;Siitonen, 2001； Ylisirniö等人，2012）。数十年至数百年积累的枯木的数量、质量和多样性被认为是影响原生林生境条件的一个主要因素（Baber et al., 2016; Hottola et al., 2009; Junninen & Komonen, 2011; Lassauce et al., 2011; Penttilä et al., 2004）。此外，森林结构的复杂性可能通过各种小气候条件增强生物多样性（brabcov<e:1>等，2022；Seidel等，2021）。然而，森林结构复杂性在塑造木材真菌多样性中的作用仍然不确定，因为迄今为止大多数证据都涉及其他生物群体（Ehbrecht et al., 2021）。在有管理的森林中，与野火恢复间隔（历史上连续火灾之间的时间为50至200年；Zackrisson, 1977）相比，轮作长度（连续砍伐之间的时间）通常相对较短（60-100年），这可以减少枯木的数量和质量（Djupström等人，2008；Jonsell等人，1998；Siitonen等人，2000），并进一步破坏枯木输入和腐烂阶段的连续性(Hottola等人，2009；Penttilä等人，2004；Ylisirniö et al., 2012)。因此，了解采伐对真菌群落的影响对于预测长期北方森林多样性以及指导国家和国际管理工作至关重要（Dinerstein等人，2020；欧盟委员会，2022；联合国环境规划署，2021）。大多数关于北方木材真菌的知识来自于子实体调查，这可能会遗漏隐藏的物种，以及没有明显子实体的物种，因此可能低估多样性（Boddy et al., 2014; Halme & Kotiaho, 2012）。尽管越来越多的研究使用DNA元条形码来补充子实体数据，但它们要么侧重于单个原木而不是林分尺度的多样性（Lindner等人，2011；Ottosson等人，2015；Ovaskainen等人，2013；Rajala等人，2012；Runnel等人，2015；Saine等人，2020），研究温带森林而不是北方森林（Rieker等人，2024），或针对土壤真菌而不是木材真菌（Heine等人，2021）。重要的是，目前还没有研究将分子和子实体数据结合起来，以覆盖北方森林火灾后和砍伐后的整个演替梯度。唯一可比较的时间序列研究（Junninen et al., 2006）仅依赖于子实体调查，可能遗漏了基于dna的方法捕获的重要多样性模式。 在这里，我们结合DNA元条形码和子实体调查来评估真菌多样性如何响应(i)枯木特征和（ii）森林结构特征在瑞典北部北方针叶林。为了评估森林火灾和砍伐后真菌群落随时间的变化情况，我们采用了一种时间序列方法，代表了两种截然不同的轨迹：一种是未经管理的火灾时间序列（未进行木材生产管理；森林火灾发生后4-375年），另一种是经过管理的砍伐时间序列（砍伐后1-109年）。我们探索了DNA元条形码和传统的子实体调查是否捕获了相同的时间模式，并测试了以下假设：我们预测，在未经管理的火灾中，木材真菌物种丰富度（总数，木链菌和红色名单物种）高于经过管理的砍伐林，并且随着时间的推移而增加，在未经管理的原始森林中达到峰值。我们预计这些差异将对应于有管理的林分和未管理的林分之间的显著不同的群落组成，其特征是在未管理的林分和老林分中有更多的专门和稀有物种。真菌多样性模式可以通过两个层次的生境特征来解释。首先，我们预测了枯木特征（数量、质量和多样性），以解释total、Agaricomycete和红色名单真菌的物种丰富度。其次，我们预测水平和垂直森林结构复杂性来解释额外的变化。通过使用这种方法，我们的目标是提供关键的见解，以了解北方森林中两种主要的干扰制度-轮作森林砍伐和森林火形木材-如何在北方森林演替中栖息真菌群落。
