此外，紫杉对许多大型食草动物都有剧毒，但鹿和某些反刍动物除外（Cortinovis & Caloni, 2015; Thomas & Polwart, 2003），因此可能会取代更容易被啃食的物种（Dhar 等人，2007 年；García & Ramón Obeso, 2003）。另一方面，Taxus树皮薄，再生困难，尤其是在干燥环境中，因此易受火灾影响（Mola等人，2014；Thomas & Polwart, 2003），而且其生长缓慢、幼苗繁殖率低，进一步延迟了火灾后的种群恢复（Thomas & Polwart, 2003）。因此，在过去由多种巨型动物提供高水平草食的生态系统中，Taxus很可能会受到青睐（Davoli 等人，2023 年），但频繁的火灾则会使其受到不利影响。灭绝发生在智人到来的公元前约 5 万年，即最后一个冰川期（Bergman 等人，2023 年；Svenning 等人，2024 年），当时由于气候寒冷干燥，森林及其树种的分布和数量都大大减少（Svenning 等人，2008 年；Willis & van Andel, 2004 年）。现代保护实践越来越注重恢复生态功能（Perino 等人，2019 年），而长期数据（如功能基线）的作用早在近 20 年前就已得到认可（Willis 等人，2005 年，2010 年）。退化前基线可为人类引起的退化之前的系统提供独特的生态见解，为现代恢复工作提供重要的背景资料。然而，我们注意到，要将这些见解与现代恢复工作相协调，就必须承认当代生态的复杂性，如不断变化的气候系统和其他人为影响，如野火的引发，这可能需要在退化前基线之外进行额外的考虑。要为当前和未来的系统建立退化前基线，温暖的间冰期条件最为相关。欧洲的末次间冰期（Eemian；~129,000-116,000 BP）是全新世之前最近的一次间冰期。它发生在第四纪晚期巨型动物灭绝之前，动物结构与之前的 1000 万年或更早时期大致相当（Blanco 等人，2021 年；Croitor & Brugal，2010 年）。这一时期在地质学上足够新，足以限制进化变化，因为大多数范围内的物种已经存在（Van Kolfschoten，2000 年）。最后，末次间冰期在气候上可与变暖的全新世相媲美，尤其是在其中层阶段，并被描述为在比工业化前基准温度更高的条件下评估环境响应和气候反馈的试验平台（Kalis 等人，2003 年；Kühl 等人，2007 年；Salonen 等人，2018 年）。因此，末次冰期为晚第四纪动物降级之前温暖条件下的植被结构和动态提供了一个长期的代表性基线（Smith 等人，2018 年）。利用 REVEALS 模型（Sugita，2007 年）进行的基于花粉的植被重建显示，欧洲末次冰期的栎类和榛类植被非常丰富（Pearce 等人，2023 年）。利用末次冰期原始花粉数据进行的研究显示，榛属植物的峰值高达 50%（Rychel 等人，2014 年；Suchora 等人，2022 年）。全新世的栎属和榛属植物过去的丰度比较清楚，REVEALS建模显示，在公元前8200-5700年，栎属植物覆盖率为1%-15%，榛属植物平均覆盖率为10%-15%（Githumbi等人，2022年；Serge等人，2023年）。在末次间冰期，不同程度地存在 Taxus（中欧为 3%-15%；Malkiewicz，2018 年；Schläfli 等人，2021 年）。在全新世，Taxus 花粉并不常见，覆盖率也很低（2%-6%；Deforce & Bastiaens, 2007; Pérez Díaz et al.）在本研究中，我们比较了柞树、榛树和紫杉的丰度，以评估它们的种群在温带森林生物群落晚第四纪巨型动物灭绝前后的变化情况。我们利用最新的 REVEALS 重建（Pearce 等人，2023 年；Serge 等人，2023 年）量化了末次冰期和全新世早中期每种分类群的覆盖率百分比。虽然本研究无法直接测试巨型动物对植被的影响，但我们评估了观测到的丰度差异与气候变异的相关程度，并估算了残差。

北美东北部的落叶林由外生菌根（EM）树和丛生菌根（AM）树混合组成。然而，由于土地利用的遗留问题和其他因素，EM 树减少，AM 树占优势的情况同时增加，这可能会限制森林生态系统功能的发挥。我们研究了分散的 EM 树斑块和来自当地 EM 树占主导地位的森林的土壤接种物如何影响以 AM 树为主的次生林中的 EM 真菌定植、EM Tsuga canadensis、Pinus strobus 和 Quercus spp.树苗的存活和生长。在纽约的三片次生林中，幼苗被种植在优势AM槭树和零星的EM桦树旁。一部分树苗还接受了来自当地 EM 优势森林的土壤接种物。我们对幼苗的存活率和高度生长进行了为期两年的监测，然后测量了幼苗嫩枝的生物量，评估了EM定植情况，并从幼苗根部鉴定了EM真菌。与种植在AM Acer树附近的幼苗相比，种植在EM Betula树附近的所有属的幼苗的EM定植率和真菌丰富度都更高。接种 EM 森林土壤只增加了 AM Acer 附近幼苗的 EM 定殖率和真菌丰富度，这在缺乏本地 EM 真菌的地区非常有效。幼苗根部的 EM 真菌总多样性在 EM Betula 附近最高，其中包括许多通常与成熟树木相关的类群。相比之下，AM Acer 附近的 EM 真菌群落稀少，主要由相对较少的孢子库真菌类群主导。虽然不同处理的幼苗存活率并无差异，但土壤接种和靠近 EM Betula 可增加松树和铁杉第二年的高度生长，而单独的土壤接种则可显著提高柞树幼苗的枝量。综述。农业用地的遗留问题造成了以AM树为主的广阔次生林。在这些森林中，由于缺乏EM真菌，在现有的EM树斑块外建立EM树幼苗可能会受到阻碍，但来自EM树为主的森林的本地土壤接种物可将本地EM真菌重新引入缺乏已建立的EM树的次生林中。

<h2>1 INTRODUCTION</h2> <p>Symbiosis plays a key role in plant biology affecting growth, adaptation, and speciation (Uroz et al., <span>2019</span>). The plant and fungal kingdoms engage in symbiotic relationships such as mycorrhizae and endophytic associations, supporting nutrient uptake and stress tolerance. Fungi also play key roles in decomposition, nutrient cycling, and disease dynamics, underscoring their importance in ecosystem health and agriculture. For example, some temperate grasses within the Poaceae family, establish symbiotic associations with a myriad of microbes including asexual <i>Epichloë</i> endophytes (Ascomycota: Clavicipitaceae) and arbuscular mycorrhizal (AM) fungi (Glomeromycotina) in shoots and roots, respectively. These symbionts often occur simultaneously and influence enemies of the plant, including herbivorous animals, via changes in plant nutritional and defensive traits (Casas et al., <span>2022</span>; Omacini et al., <span>2006</span>; Perez et al., <span>2021</span>). However, predicting the impact of simultaneous symbioses on plant–herbivore interactions remains challenging since they are usually studied separately.</p> <p>As protective mutualists, endophyte anti-herbivore defences mainly operate directly via the production of toxic alkaloids (Bastías et al., <span>2017</span>). In terms of alkaloids, four major groups of endophyte alkaloids have been reported including ergot alkaloids, indole-diterpenes, pyrrolizidines (e.g. loline) and pyrrolopyrazines (e.g. peramine) (Berry et al., <span>2019</span>; Schardl, Florea, et al., <span>2013</span>; Schardl, Young, et al., <span>2013</span>). Nonetheless, only grasses harbouring endophytes that putatively produce peramine (e.g. anti-chewing insect defences) and loline (e.g. anti-aphid and anti-chewing defences) are desirable in pastures because they confer herbivorous insect resistance without affecting grazing mammals (Young et al., <span>2013</span>). While lolines are strongly insecticidal (i.e. toxic), peramine often acts as a potent insect-feeding deterrent (Saikkonen et al., <span>2016</span>). Additionally, endophytes can have a detrimental effect on herbivores by stimulating the increased production of host plant defences (Bastías et al., <span>2017</span>).</p> <p>As nutritional mutualists, AM fungi often enhance plant nutrient supply (mainly phosphorous and nitrogen) through their highly specialized intracellular structures (i.e. arbuscules and vesicles) and their extensive hyphal networks that capture soil nutrients otherwise unavailable for plants (Lanfranco et al., <span>2018</span>). In addition to improving plant nutritional quality, a growing number of reports suggest that AM fungi also improve host resistance to both herbivorous insects (Koricheva et al., <span>2009</span>) and pathogens (Gernns et al., <span>2001</span>). Specifically, for piercing-sucking aphids, AM fungi have been reported to have positive (Hartley & Gange, <span>2009</span
在促进作用的情况下，土壤中的内生渗出物已被证明可以刺激AM的定殖，甚至延长根外菌丝体（Novas等人，2010；Vignale等人，2018）。禾本科植物的另一种高效抗食草动物机制是它们能够从土壤中积累大量的硅（Si）（Alhousari & Greger，2018）。硅的抗食草动物防御机制通过多种机制发挥作用，包括强化植物组织，从而磨损食草动物的口器，阻碍组织穿透，干扰消化和营养获取（Andama 等人，2020 年；Cibils-Stewart 等人，2023 年；Massey & Hartley，2009 年），或改变食草动物的免疫力（Cibils-Stewart 等人，2023 年）。硅的积累也会影响植物对一系列次级代谢产物的分配（Hall 等人，2019 年），包括生物碱（Hall 等人，2021 年）。有人认为，与次生代谢物的产生（即碳基化合物）相比，硅可能是一种更廉价的食草动物防御代谢物（即物理防御），许多植物类群报告的硅与酚类和单宁之间的负相关关系支持了这一假设（Cooke & Leishman, 2012; Frew et al、有证据表明，当植物被Epichloë内生菌（Cibils-Stewart等人，2020，2021，2023；Huitu等人，2014）或AM真菌（Frew等人，2017）定殖时，植物体内的Si积累会增加，尽管这并非普遍现象（AM：Johnson等人，2022；Vega等人，2021；内生菌：Johnson 等人，2023 年）。然而，尽管这两种共生体在自然界中同时存在，但尚未有研究探讨这两种共生体是否相互作用影响植物体内的硅积累和相关的食草动物抗性，或硅供应是否影响共生体介导的食草动物防御。目前还不清楚内生真菌和调幅真菌是如何相互作用的，以及对碳的潜在竞争是否会影响硅的积累和生物碱防御作用的产生。此外，Si 对蚜虫等刺吸式昆虫的防御效果还不确定（Massey 等人，2006 年；Johnson 等人，2020 年；但见 Reynolds 等人，2009 年）。然而，由于共生体产生的代谢物（即内生生物碱）通常会使植物付出能量代价（即碳）（Bastías et al、本研究的目的是调查硅供应、多共生关系（内生真菌和调幅真菌）以及蚜虫食草的存在/不存在在禾本科植物中物理（硅）或共生体介导的（内生生物碱）抗蚜防御的产生和有效性方面的相互作用。为此，我们确定了硅供应、Epichloë内生菌、AM真菌以及全球害虫Rhopalosiphum padi的草食是否会改变(i)禾本科植物的物理防御（即叶面硅浓度）以及(ii)植物生长、初级化学和生理。此外，我们还确定了这些因素单独或组合是否会发生加成或非加成（即拮抗、加成或协同）改变，(iii) 共生特征，包括调幅真菌定殖和内生生物碱的产生。虽然在一些植物-内生真菌共生中，菌丝浓度与生物碱之间存在正相关关系，但必须注意的是，生物碱的生产可能并不总是表生真菌内生菌的表现变量。最后，评估了硅供应、Epichloë真菌内生菌和 AM 真菌之间的相互作用对蚜虫害虫（iv）种群和个体表现的影响。
