Arctic and alpine, high latitude and high elevation environments are one of the most stressful environments for species to inhabit. This harshness manifests itself in lower species richness in comparison to more southern vegetation zones (Francis & Currie, 2003). Furthermore, the climatic oscillations—past and predicted—have the most dramatic effect on these ecosystems. For example, in regions of continental ice sheets—the northernmost part of Western Europe and North America—the Arctic species assemblages are no older than a few thousands of years, which is a relatively short period from an evolutionary perspective. Although similar environments may have existed further south during the Ice Age, allowing some preadaptation for the Arctic species, the current habitat is a unique combination of environmental factors such as the climate, soil, bedrock, and photoperiod. Hence, understanding the evolutionary forces shaping Arctic‐alpine species will be important for predicting these vulnerable environments’ population viability and adaptive potential in the future. In this issue of Molecular Ecology Resources, Nowak et al. (Molecular Ecology Resources) present extensive genome‐wide resources for an Arctic‐alpine plant Draba nivalis. This adds a valuable new member into the cabbage family models for evolutionary genetics and adaptation studies, to accompany e.g., Arabidopsis (Nature Genetics, 43, 476; Nature, 408, 796), Arabis (Nature Plants, 1, 14023) and Capsella (Nature Genetics, 45, 831). A whole new avenue will open up for molecular ecological studies not only for D. nivalis, but the whole large Draba genus with its diverse ecological and evolutionary characteristics.

北极-高山植物分子生态学新模式种
北极和高山、高纬度和高海拔环境是物种栖息的压力最大的环境之一。与更南部的植被区相比,这种严酷性表现在物种丰富度较低(Francis & Currie,2003 年)。此外,过去和预测的气候波动对这些生态系统的影响最为显着。例如,在大陆冰盖地区——西欧和北美的最北端——北极物种组合的年龄不超过几千年,从进化的角度来看,这是一个相对较短的时期。尽管在冰河时代更南方可能存在类似的环境,允许北极物种进行一些预先适应,但目前的栖息地是气候、土壤、基岩和光周期。因此,了解塑造北极高山物种的进化力量对于预测未来这些脆弱环境的种群生存能力和适应潜力非常重要。在本期分子生态资源,诺瓦克等。(分子生态学资源)为北极高山植物Draba nivalis提供了广泛的全基因组资源。这为用于进化遗传学和适应研究的卷心菜家族模型增加了一个有价值的新成员,例如拟南芥 ( Nature Genetics , 43, 476; Nature , 408, 796)、Arabis ( Nature Plants , 1, 14023) 和 Capsella (自然遗传学, 45, 831)。一条全新的途径将为分子生态学研究开辟一条全新的途径,不仅针对D. nivalis,而且针对具有多样化生态和进化特征的整个大型 Draba 属。
