Exploring patterns and causes of intraspecific trait variation is crucial for a better understanding of the effects of climate change on plant populations and ecosystems. However, our current understanding of the intraspecific trait variation is mainly based on structural (morphological) traits, and we have limited knowledge on patterns and causes of variation in biochemical traits (e.g., leaf pigments), which are also crucial for plant adaptation. As a result, we also do not know how similar the climatic effects on structural versus biochemical traits are. Using plant traits from 110 genotypes representing 11 Festuca rubra populations grown in 4 different climates, we studied trait covariation among structural traits (linked to fitness, resource use, gas exchange, and reproduction) and biochemical traits (linked to photosynthesis, photoprotection, and oxidative stress). We also disentangled the relative role of the climate of origin and the climate of cultivation in the structural ver..., Study species and sampled localities for plant material In the experiment, we used Festuca rubra ssp. rubra, a widespread perennial grass species that occurs in temperate grasslands in Europe. This species can reproduce both by seeds and clonally by rhizomes. The experimental plants of this species were collected in 2014 from 12 natural localities representing factorially crossed precipitation and temperature gradients corresponding to the SeedClim Grid (Meineri et al. 2014) in Western Norway. This grid represents an independent combination of three levels of mean summer temperature (4 warmest months, 6.5 °C, 8.5 °C and 10.5 °C) with four levels of annual precipitation (600, 1300, 2000 and 2700 mm). The plant material used in the current study has been collected for previous studies that have set up the experiments and provided data also for this study (Münzbergová et al. 2017). From each locality, at least 40 plants of F. rubra (at least 1 m apart) were collected in the growing season...,

探究种内性状变异的模式与成因,对于深入理解气候变化对植物种群及生态系统的影响至关重要。然而,当前学界对种内性状变异的认知主要基于结构(形态)性状,而对生化性状(如叶片色素)变异的模式与成因所知有限——尽管生化性状同样对植物适应至关重要。因此,我们尚不清楚气候对结构性状与生化性状的影响程度是否相似。 本研究以生长于4种不同气候条件下的11个紫羊茅(Festuca rubra)种群的110个基因型的性状数据为基础,分析了与植物适合度、资源利用、气体交换及繁殖相关的结构性状,以及与光合作用、光保护和氧化胁迫相关的生化性状之间的性状协变关系;同时厘清了源生境气候与栽培气候在结构性状(原文截断为structural ver...)中的相对作用。 ## 研究物种与植物材料采样地点 本实验所用材料为紫羊茅原亚种(Festuca rubra ssp. rubra),这是一种广泛分布于欧洲温带草原的多年生草本植物。该物种既可通过种子进行有性繁殖,也可通过根状茎进行无性繁殖。实验用植株于2014年采自挪威西部对应SeedClim网格(Meineri等,2014)的12个自然样地,这些样地涵盖了降水与温度梯度的因子交叉设计。该网格包含3个夏季平均温度水平(取最暖4个月,分别为6.5℃、8.5℃与10.5℃)与4个年降水量水平(600、1300、2000及2700 mm)的独立组合。 本研究所用的植物材料,采自此前已开展相关实验并为本次研究提供数据的前期研究(Münzbergová等,2017)。在每个样地的生长季中,我们至少采集了40株彼此间距不小于1米的紫羊茅植株...
