植物竞争不仅会受到植物功能特性的影响，还会受到土壤微生物介导的适应性差异的影响。干旱等气候条件会进一步影响植物竞争。然而，人们对土壤微生物和干旱如何与具有不同根系特征的植物物种相互作用以及如何影响植物竞争结果知之甚少。我们在中国温带草原上种植了三种共生植物（Stipa krylovii、Artemisia frigida、Agropyron cristatum），将其单株或混种，并将植物组合置于五种土壤接种体（S. krylovii、A. frigida、A. cristatum 的根相关土壤、三种根区土壤的等量混合物和灭菌土壤）以及干旱处理中。这三个物种在竞争能力上表现出明显的差异，A. cristatum > S. krylovii > A. frigida，土壤接种剂或干旱处理并没有改变顺序。植株的相对产量（RY）受土壤接种物、干旱和植株排列的影响。最强的竞争者 A. cristatum 具有较高的根系总长度、根系表面积和根系体积，经历了更多的生物负反馈，而干旱加剧了这些负效应的程度。相反，最弱的竞争者 A. frigida 具有较高的比根长度，往往具有中性或积极的生物反馈，而干旱则没有影响。此外，三个物种的 RY 和适应性差异（反映为混合物中的竞争能力）受根系性状和植物-土壤反馈的影响不同。A.cristatum的RY可以通过混合物中的反馈效应预测，而适应性差异主要与根系性状有关。A. frigida（最弱的竞争者）的有效年限和适应性差异都可以通过根系性状差异和反馈效应预测。我们的研究表明，共存物种的竞争结果取决于根系性状和混合物中特定物种的 PSF 效应。未来的工作应该研究植物竞争和土壤微生物异质性如何与气候变化共同影响植物共存的机制。

植物-菌根类型被认为是植物功能特征的一个整合因素，但目前对这些关系的了解大多来自对不同植物类群的研究，在这些研究中，菌根类型的影响无法被分离出来。除了影响碳-养分交换外，与不同菌根类型结合的植物往往在多个性状上存在差异，从而对无数地下过程产生影响。我们利用两个种植有小叶杨（一种能同时与丛枝菌根真菌（AM）和外生菌根真菌（ECM）结合的树种）的普通花园，研究了菌根类型优势在多大程度上影响根系性状以及整个根系经济空间的性状关系。虽然P. fremontii同时形成了AM和ECM结合，但个体表现出的菌根类型优势主要受花园位置的影响。低海拔花园中的树木，无论产地如何，主要由 AM 真菌定殖，而高海拔花园中的树木主要由 ECM 真菌定殖。在低海拔花园的根系中，AM 真菌的定殖率与特定根长呈负相关，这表明对觅食根的投资是权衡利弊的结果。相反，在高海拔花园的根系中，ECM 的定植率与根组织密度呈负相关，这表明在资源获取与根系生长/防御之间可能存在权衡。菌根类型之间的所有其他根系经济性状保持相似。虽然以 AM 和 ECM 为主导的树木（和花园）之间的根系性状差别不大，但它们之间的关系在每个花园中都有所不同，这表明在一个物种中存在独特的策略和性状权衡。随着全球变化不断改变环境，像P. fremontii这样经历了一系列非生物条件的物种，可能预示着其他树种会如何改变根系的性状和策略以应对变化。在期刊博客上免费阅读本文的通俗摘要。

高纬度和高海拔地区的树线被认为是全球变化的哨兵。这表现为乔木和灌木的加速侵占以及植物生产力的提高，目前尚不清楚这对这些生物群落碳平衡的影响。鉴于许多树线土壤中存在大量的土壤有机碳储量，我们在此想知道，引入高产植物是否会通过根瘤效应加速碳循环，以及某些土壤是否会比其他土壤更容易受到正向引力的碳损失。为了验证这一点，我们在瑞典亚北极地区和秘鲁安第斯山脉的树线上下采集了有机土壤和矿物质土壤样本。然后进行了一项温室实验，利用自然丰度标记和 C4 种植物 Cynodon dactylon 来量化植物诱导的土壤矿化率变化（根瘤效应）和新碳形成。实验期间监测了一些环境、植物、土壤和微生物参数，以补充对土壤碳循环的观察。在实验开始时，引诱作用主要为正，然后在植物生长季节，所有土壤中的引诱作用系统性地减弱，到植物衰老期实验结束时，引诱作用主要为负。与引力的方向无关，有机土壤的引力总是大于相应的矿质土壤，而矿质土壤的 C 含量较高最能说明这一点。综合整个研究期间的情况来看，引肥（正向和负向）对土壤碳平衡的总体影响大多可以忽略不计。尽管在瑞典亚北极苔原的有机土壤中观察到了土壤碳的净损失。最值得注意的是，根据取样时间的不同，正负引物效应并不相互排斥，而是普遍存在于不同的生态系统中。引效应的方向似乎随着植物生产力、根瘤菌圈碳输入量和养分吸收量的变化而波动。这突出表明，如果我们想了解生态系统尺度上的引诱效应，就需要进行长期的综合研究，而且温室和实验室研究必须经过现场验证，以实现可靠的生态升级。在期刊博客上免费阅读本文的通俗摘要。
