比根长较高；约翰逊,2010;Neuenkamp et al., 2018)。然而，物种内部的这种变化仍未被探索。在种内水平，植物群体可以通过两种不同的机制对土地利用放弃做出反应：植物群体的遗传变化（即群体遗传组成的变化或影响世代性状表达的持续表观遗传修饰）和表型可塑性，表型可塑性描述了基因型在不同环境下产生不同表型的能力（Callaway等人，2003；Miner等人，2005;Miryeganeh & Saze, 2019）。迄今为止，实地实证研究报告了管理草原与废弃草原种群之间SLA和LDMC的增加和减少，以及这些性状未检测到的变化(Castro等人，2010；Celis等人，2017；Louault等人，2005;Pakeman, 2013； Targetti等人，2013；Volf et al., 2016)，但我们缺乏在普通花园条件下的比较研究，这些研究可以将由表型可塑性引起的性状变化与由进化变化驱动的性状变化区分开来（但参见Cid et al., 1989; Detling & Painter, 1983，关于在实验放牧中检测到的进化变化的证据）。表型可塑性使植物能够根据当时的条件调整其性状（Miner et al., 2005），并有助于土地利用变化下的种群持久性。然而，对于草地专家来说，由于废弃草原的光可用性和其他环境条件变得不理想，已知这会导致种群规模和种群内遗传多样性下降（Aavik等人，2019；Reinula等人，2021），这反过来可能会降低功能性状多样性。土地利用变化还可能通过影响草原内的环境异质性来影响性状多样性（Karbstein et al., 2020; Stark et al., 2017）。与性状手段的变化一样，性状多样性的变化可能反映了种群内的可塑性反应和遗传变异的变化。到目前为止，土地利用对功能性性状多样性的影响，特别是与种群遗传变化相关的影响，仍未得到描述。然而，这些变化需要调查，因为有越来越多的证据表明种群内遗传和功能多样性对确保生态系统功能和稳定的重要性（Prieto等人，2015；Semchenko等人，2021;Whitlock, 2014）。在这里，我们评估了表型可塑性和遗传性状变化在多大程度上驱动种群对长期放牧放弃的反应。我们研究了一种常见的草本植物Briza media的22个种群，这些种群分布在连续放牧或至少30年未放牧的地点，导致灌木和树木逐渐入侵。对于每个种群，我们测量了一系列性状(a)，其中性状表达差异是表型可塑性和进化反应对放牧放弃引发的环境条件变化的综合结果，以及(b)在标准化、常见条件下克隆后代繁殖后的性状表达差异，目的是突出性状表达的遗传差异。检验了以下假设：假设1。与连续放牧区相比，弃牧造成了更阴暗和更不均匀的光照条件，导致凋落物积累，缓冲了温度和水分条件，降低了草地中叶枯草种群规模和丰富度。假设2。由于环境的变化，放弃放牧导致性状手段向更高的表型转变，这反映了一种更具竞争性的策略，以抵抗来自周围草本植被的光竞争。更高的SLA，增强对灌木和树木遮荫的光捕获和耐受性。如果放弃后的选择主要是由于减少暴露于物理危害（如风、紫外线辐射）所致，则LDMC降低。另外，如果撂荒草原上的选择主要是由放牧动物的缺乏和叶片寿命延长的优势介导的，那么撂荒草原上的LDMC将向更高的方向转变。根系较细，比根长（SRL）较高，菌根定植率较低，表明对菌根共生的依赖程度较低。假设3。由于种群规模缩小导致遗传多样性降低，来自废弃地点的种群的性状多样性较低。另外，由于一些地区被树木遮蔽，而另一些地区保持开放，被遗弃的草原暂时提供了一个更加异质的环境，因此，被遗弃种群内的性状多样性可能会增加。 在种群内性状均值和性状多样性的情况下，我们期望通过对野外条件的可塑性响应观察到对放牧放弃的更强响应，而不是在普通条件下可检测到的遗传性状响应，因为进化响应需要更长的时间才能出现。在关于组织保护和性状多样性的其他假设的情况下，对其中一个假设的支持将表明哪个过程可能对性状表达施加更大的选择压力。
