Plant trait variability, emerging from eco-evolutionary dynamics that range from alleles to macroecological scales, is one of the most elusive, but possibly most consequential, aspects of biodiversity. Plasticity, epigenetics, and genetic diversity are major determinants of how plants will respond to climate change, yet these processes are rarely represented in current vegetation models. Here, we provide an overview of the challenges associated with understanding the causes and consequences of plant trait variability, and review current developments to include plasticity and evolutionary mechanisms in vegetation models. We also present a roadmap of research priorities to develop a next generation of vegetation models with flexible traits. Including trait variability in vegetation models is necessary to better represent biosphere responses to global change.

建立新一代的特质柔性植被模型。

植物性状变异性是从生物进化动力学（从等位基因到宏观生态尺度）变化而来的，是生物多样性中最难以捉摸但可能最重要的方面之一。可塑性，表观遗传学和遗传多样性是植物如何应对气候变化的主要决定因素，但是这些过程在当前的植被模型中很少出现。在这里，我们概述了与理解植物性状变异性的原因和后果相关的挑战，并回顾了当前的发展，以将可塑性和进化机制纳入植被模型。我们还提出了研究重点的路线图，以开发具有灵活特征的下一代植被模型。
