在过去的几十年里，许多实验研究显示了生物多样性与生产力之间的积极关系（例如Cardinale等人，2012；Tilman等人，2014）。此外，现有的少数长期生物多样性实验表明，随着时间的推移，积极的生物多样性效应变得更强，主要是由于更强的互补效应（如Cardinale et al., 2007; Reich et al., 2012; Wagg et al., 2022）。解释这一现象的生态机制仍在争论中，但越来越多的证据表明，多种机制推动了生物多样性对生态系统功能的长期积极影响（Eisenhauer et al., 2024）。生物相互作用，特别是植物与土壤生物群之间的相互作用，在加强生物多样性效应中起着至关重要的作用（Eisenhauer et al., 2012; Thakur et al., 2021; van der Putten et al., 2013）。高多样性群落生产力的提高被认为是由植物生长促进剂的积累产生的，例如菌根真菌或生物防治细菌引起的植物-土壤正反馈（PSF），或特定病原体的稀释（Eisenhauer et al., 2012）。进一步的过程包括通过群落聚集增强资源利用的互补（Reich et al., 2012; Roscher et al., 2013）和微进化过程增加生态位分化（de Giorgi et al., 2025; Zuppinger-Dingley et al., 2014）。此外，低多样性群落的生产力下降与特定植物拮抗剂的密度依赖性积累有关，这些拮抗剂会产生负PSF，降低营养水平上有益相互作用伙伴的多样性和活性，以及资源利用不平衡（Kulmatiski等人，2012；Mommer等人，2018）。为了更好地理解多样性对植物群落生产力的增强效应，研究单个物种对多样性的生产力响应是关键。各种研究表明，不同的植物物种对多样性有各种可能的生产力响应：负的、中性的或正的（例如，Hille Ris Lambers等人，2004；Marquard等人，2009；Roscher等人，2007；Thein等人，2008;van Ruijven & Berendse, 2005）。在群落中，植物物种经历与邻近植物的竞争，与其他营养水平的生物相互作用，并暴露于不同的非生物和生物环境中，这应该是不同物种对多样性的不同反应和多样性效应的基础。然而，竞争与PSF的相对重要性，特别是它如何随着植物多样性的增加而变化，人们知之甚少（Lekberg等人，2018；Reinhart等人，2021）。对于作为解释生物多样性效应随着时间的推移而增强的各种机制的复杂性如何改变单个物种的表现，我们所知的就更少了。此外，尚不清楚是否以及哪些植物性状控制了这些过程。从概念上讲，有人提出植物对PSF的差异反应应该与快慢性状谱有关（Reich, 2014），它描述了在投资促进快速生长的性状或投资防御拮抗剂的性状之间的权衡（Xi et al., 2021）。在地面上，叶片经济谱的特征（Wright et al., 2004），如较高的叶片氮浓度（NLeaf）和更大的比叶面积（SLA），表明养分的快速生长和快速周转，但对天敌的防御能力较低。因此，具有“快”性状综合征的物种应该比具有“慢”性状综合征的物种经历更多的个体负PSF。事实上，最近的一项荟萃分析表明，速生植物物种的PSF更负，支持生长-防御权衡假说（Xi et al., 2021）。然而，非生物和生物环境因素（如光、养分、土壤湿度、天敌）也可能改变植物-土壤生物群的相互作用；也就是说，PSF的强度甚至方向可能取决于环境背景（Bennett & Klironomos, 2019; Smith-Ramesh & Reynolds, 2017）。众所周知，植物多样性的增加会改变单个植物物种所经历的生长环境，但这是否会影响具有快和慢性状的物种对植物多样性增加的不同反应，在生物多样性实验中很少得到验证。最近，Zheng等（2024）在各种草地生物多样性实验中发现，随着时间的推移，生物多样性效应的增强主要是由于资源保守型物种的超产出量增加，而资源获取型物种的超产出量或减少或增加。 由于草原群落建立后可能需要数年时间，生物多样性积极效应背后的各种机制才能充分发挥作用，因此尚不清楚物种层面对植物多样性的响应是否会受到实验历史（即植物群落的年龄）的影响，这可能与实验年份的特定环境条件相混淆（Vogel et al., 2019）。因此，我们在长期生物多样性实验的14年植物群落（耶拿实验，Roscher et al., 2004）中建立了2016年在新土壤和新种子（=无历史）上播种的具有匹配物种组成的“新群落”亚样地，并将其与2002年播种的“旧群落”亚样地（=有历史）进行比较（ΔBEF实验，Vogel et al., 2019）。我们利用耶拿实验中66种植物混合物（2、4、8、16和60种）的植物生物量的时间序列数据，将每种混合物的居住（=播种）物种分为特定地块的“赢家”（高产、高产物种）和“输家”（低产量、低产物种）（图1a）。由于尚不清楚PSF的强度和方向如何随植物生命阶段变化（Kardol et al., 2013），我们还使用了植物计方法，将预生长的幼苗种植到有和没有历史的群落中。从每个特定的地块中选择两个“赢家”和两个“输家”物种作为每种混合物的植物计，以解释相同的物种在某些地块中可能是“赢家”而在其他地块中可能是“输家”（图1b）。此外，我们在所有60个实验物种的“旧”和“新”单一栽培中安装了植物计。我们检验了以下假设：在混合中，可通过与快-慢叶经济谱相关的关键性状来区分住居种中的赢家和输家。具有“快”性状的物种在高多样性混合物中是赢家，而具有“慢”性状的物种在低多样性混合物中是赢家，特别是在历史较长，即植物群落年龄增加的情况下。群落历史影响植物性能。我们预计，在低多样性下，有历史的旧群落的植物计性能低于没有历史的新群落，而在高多样性下，有历史的群落的植物计性能高于没有历史的群落。与表现优异的物种（=优胜者）相比，表现不佳的物种（=失败者）在低多样性混合物中受到历史的负面影响更多，而在高多样性混合物中从历史的积极影响中获益较少，导致有历史的群落中胜利者和失败者植物计的性能差异大于没有历史的群落。实验设计总结，包括对60种植物及其单一栽培的66种不同物种丰富度的植物混合物（2、4、8、16和60种）进行生物多样性实验的长期数据分析。(a)时间序列数据用于确定特定地块的“赢家”（表现优异、产量过高的物种，用红色表示）和“输家”（表现不佳、产量不足的物种，用蓝色表示）。(b)每种混合物的两个“输家”和两个“赢家”物种作为植物计种植在新土壤上的“新群落”和“旧群落”及其各自的单一栽培的子地块上。植物计测量的性状数据被用来测试胜利者和失败者之间的性状差异。在BioRender中创建。Roscher， C.
