植物系统发育多样性的全球热点
具有高度独特系统发育多样性(PD)的地区是保护的优先目标。在这里,我们分析了植物PD的全球分布,尽管植物是大多数陆地栖息地的基础和人类生计的关键,但人们对植物PD的了解仍然很少。利用最近完成的全球维管植物综合清单,我们确定了独特植物PD的热点,并验证了三个假设:(1)PD比物种多样性分布更均匀;(2)最高PD的区域(通常称为“热点”)不会使累积PD最大化;(3)需要许多生物群系来最大化累积PD。我们的研究结果支持所有三个假设:覆盖50%的全球植物PD所需的区域是覆盖50%的物种所需区域的两倍以上;累积PD最大化的区域与个体PD突出的区域存在显著差异;虽然(亚)热带湿润森林地区在整个PD热点地区占主导地位,但其他森林类型和开放生物群落也必不可少。在人类世中保护PD(包括保护一些相对物种贫乏的地区)是一项全球性的、日益被认可的责任。在强调了具有突出独特植物PD的国家之后,现在需要进一步分析以充分了解植物PD的全球分布及其在空间尺度上的相关保护要求。

期刊介绍: New Phytologist is a leading publication that showcases exceptional and groundbreaking research in plant science and its practical applications. With a focus on five distinct sections - Physiology & Development, Environment, Interaction, Evolution, and Transformative Plant Biotechnology - the journal covers a wide array of topics ranging from cellular processes to the impact of global environmental changes. We encourage the use of interdisciplinary approaches, and our content is structured to reflect this. Our journal acknowledges the diverse techniques employed in plant science, including molecular and cell biology, functional genomics, modeling, and system-based approaches, across various subfields.
