Many plants are responding to increases in spring temperatures by advancing their leaf‐out and flowering times in temperate regions around the world. The magnitudes of species' sensitivities to temperature vary widely, and patterns within that variation can illuminate underlying phenological drivers related to species' life histories and local‐scale adaptations.The USA National Phenology Network (USA‐NPN) and the National Ecological Observatory Network (NEON) are two rapidly growing, taxonomically and geographically extensive phenology data resources in the USA that offer opportunities to explore emergent properties of spring phenology.Using observations of leaf‐out and flowering in temperate deciduous plant species from USA‐NPN (2009–2024) and NEON (2014–2022), we estimated species‐level flowering (n = 164) and leaf‐out (n = 136) sensitivities to temperatures of the preceding months, obtained through PRISM. We used the results to assess differences in sensitivities between the two datasets and among life history traits (e.g. introduced or native status, seasonal timing and growth habit) and to explore latitudinal patterns in sensitivity among and within species.We found significant relationships between temperature and leaf‐out phenology (2009–2024 for 109 (80%) species, ranging from −7.4 to −1.3 days/°C, and between temperature and flowering phenology for 140 (85%) species, ranging from −8.0 to −1.1 days/°C.Plant sensitivities were highly consistent among the USA‐NPN and NEON datasets, suggesting these datasets can be reasonably combined to expand the coverage of publicly available phenological data across the USA.Introduced species showed stronger sensitivity to temperature than native species for both leaf‐out (−0.8 days/°C difference) and flowering (−0.7 days/°C difference). The strongest (i.e. most negative) leaf‐out sensitivities to temperature were associated with earlier leaf‐out dates and strong flowering sensitivities.Latitudinal analyses within and across species indicate that flowering and leaf‐out sensitivities are both stronger at lower latitudes.Synthesis. Phenological ‘big data’ encompassing over 100 species across the eastern USA shows that leaf‐out and flowering occur earlier with warmer temperatures and that native species and individuals at high latitudes tend to have weaker temperature sensitivities than introduced species and more southern plants; these findings suggest adaptations within and across species to avoid leafing out and flowering under harsh environmental conditions.

植物物种对生长、繁殖和生存的资源分配不同，导致性状组合代表了对各种环境条件的适应策略（Chapin III et al., 1993; Reich, 2014; Wright et al., 2004）。地上性状的全球变异是用形式和功能的全球谱来描述的，它区分了性状变异的两个主轴。第一个对比了快速的资源获取策略与缓慢的资源节约策略（Wright等人，2004），第二个与植物和种子大小有关（Díaz等人，2016;Reich, 2014）。此外，还描述了地下性状的其他策略轴，其中协作轴描述了获取土壤资源的策略梯度。这包括通过直接根吸收获取资源的自己动手策略的植物，以及通过与菌根真菌形成关系来获取物种外包资源的植物（Bergmann et al., 2020; Weigelt et al., 2021）。有证据表明，最初描述为单个物种的功能策略变化的主要轴也可以在群落水平上表现出来。这是由于栖息地过滤选择了一个群落中多个物种的一致特征（Bruelheide et al., 2018）。这些社区水平的性状反应通常用丰度加权平均性状值（CWMs）来描述。CWMs已被证明对不同尺度的环境梯度有不同的响应。例如，在全球水平上，与保守策略相关的植物性状的CWMs与降水梯度密切相关，而与植物大小和养分获取相关的性状与温度密切相关（Bouchard et al., 2024; Joswig et al., 2022; mole et al., 2014; Xu et al., 2023）。此外，在区域尺度上，Li等人（2017）观察到降水与与菌根定植相关的CWM根系性状之间存在很强的相关性，而在局部尺度上，Schellenberger Costa等人（2017）观察到资源获取性状与降水之间存在正相关关系。由于植物性状可以影响生物地球化学过程的速率（Chacón-Labella等人，2023），气候和群落层面策略的变化都可以影响生态系统功能（Freschet等人，2010；Neyret等人，2024;Reich, 2014）。例如，Manning等人（2015）发现年平均温度和CWM叶片氮含量对土壤碳都有显著影响，Huxley等人（2023）发现气候对地上净初级生产力有显著的直接和间接性状介导的影响。然而，这些研究大多只关注少数个体性状，通常是叶片性状，而不是整个植物的策略变异，而且大多数研究没有纳入根性状（Carmona et al., 2021; Cebrián-Piqueras et al., 2021; Freschet et al., 2010）。这可能是由于根性状测量的技术困难和相应的数据缺乏，特别是在研究不足的地区（De Deyn等人，2008；Iversen等人，2017;lalibert<e:1>, 2017）。因此，在了解直接和间接、性状介导的气候效应在驱动生态系统功能中的相对重要性，特别是地上和地下植物功能性状的相对作用方面仍然存在重大差距。在这里，我们重点关注生态系统功能的一个方面，即碳储存，它在减缓气候变化方面起着至关重要的作用（Houghton, 2007； Lewis等人，2004）。越来越多的证据表明，社区水平（CWM）性状变异会影响碳储量（Conti & Díaz, 2013; Freschet et al., 2012; varga - larreta et al., 2021）。具体来说，木材的数量及其碳含量是地上和地下碳储存的主要驱动因素（Conti & Díaz, 2013）。因此，与生物量生产相关的特征和单位生物量结构投资的增加预计将直接影响碳储量（Baker等人，2004；mole等人，2009）。一些研究报告了地上CWM性状与碳之间的关联，包括叶片碳浓度较高的较高植被与较高碳储量之间的关联（Shen, Gilbert, et al., 2019; Yang et al., 2019）。此外，根系性状还可以通过对慢速策略轴或协同策略轴的贡献来影响地上和土壤碳储量。与保护和外包轴相关的根系性状（如高干物质含量和寿命）与高碳储量相关，而与自己动手和快速策略轴相关的根系性状（如比根长度和根氮浓度）与高资源周转率和低碳储量相关（Lachaise等，2022；Wen等，2022）。 然而，虽然只有少数研究评估了根系性状与碳储量的关系，但将地上和地下性状结合起来的研究就更少了（但参见Chanteloup &； Bonis, 2013; Craine et al., 2002; Orwin et al., 2010）。虽然已经描述了许多性状与碳的关系，但这些关系并不普遍一致（Feng & Dietze, 2013）。这可能是由于尺度问题，但也因为碳储存的驱动因素因生态系统类型、土地管理和气候背景而异（Peters等人，2019；Van der Plas等人，2020）。除了众所周知的性状对气候条件的响应外，土地利用还可以驱动植物功能策略的变化（Allan et al., 2015）。集约土地利用，包括农业和放牧活动，往往导致物种向生长迅速、繁殖产量高的物种转移，而牺牲了性状保守、寿命较长的物种（Flynn等人，2011；Laliberte等人，2010；Schellenberger Costa等人，2017）。这种转变可以减少碳储量，因为这些快速生长的物种通常具有较低的木材密度和较短的根系寿命，从而导致更快的碳库周转（Garnier et al., 2004）。此外，土地利用的变化会破坏植物与土壤共生体之间的关系（De Deyn et al., 2008），并会改变养分有效性、土壤化学和微生物活动。这些土壤特征也可能在碳循环中发挥重要作用，直接或通过影响植物群落功能性状组成（Joswig等人，2022）和调节气候和土地利用的影响（de Castilho等人，2006；Hartley等人，2021；Manning等人，2015）。性状-碳关系在不同的生物群落之间也可能不同（De Deyn et al., 2008）。例如，虽然地上性状可以解释森林中地上储量的碳储量，但地下性状可能更好地解释地下生物量和资源分配高的系统（如草地）中的碳储量（Ottaviani et al., 2020）。这可能意味着在温带系统中描述的关系不能转移到其他生物群系，例如在全球碳储存中起主要作用的热带生态系统。然而，这些系统中特征-功能关系的证据很少（Finegan et al., 2015）。因此，有必要进一步了解植物功能策略如何与土地利用强度和气候条件相互作用，从而影响热带生态系统的碳储量。本研究在乞力马扎罗山沿热带大海拔梯度，从热带稀树草原到森林再到高山生态系统，评估了群落特征组成的变化及其与地上和地下有机碳储量的关系。这种梯度还包括土地利用的变化，因为中低海拔的生态系统经历了栖息地的干扰和土地利用的转变（Misana, 2012）。我们假设，在乞力马扎罗山的气候梯度上，植物地下和地上性状在群落水平上存在协调，在高降水、高土地利用强度和中等温度的生态系统中，群落具有获取策略，而在低降水和更极端温度的生态系统中，群落具有保守策略（假设1）。此外，我们
