Abstract
Horseshoe crabs are unique living fossils that have remained almost unaltered through 400 million years of global change. They face rapid worldwide declines under increasing anthropogenic pressure. Using comprehensive geographic and genomic sampling combined with approaches that integrate DNA with environmental and climatic datasets, we assessed the population genetic structure, demographic histories, and vulnerability to future climate change in three out of four extant horseshoe crab species, all centered in Asia. Our study highlights that the Sunda Shelf, a complex and dynamic shallow-marine landscape, has been the sole repository of most genetic diversity among all three Asian species, and therefore crucial to the long-term survival of horseshoe crabs. Our study not only provides the first genomic baseline data for the evaluation of Asian horseshoe crabs’ conservation status but also identifies core habitats that potentially act as refugia and corridors for Asian horseshoe crab populations with impending anthropogenic global warming.
马蹄蟹是一种独特的活化石,在 4 亿年的全球变化中几乎没有改变。在日益增加的人类活动压力下,它们在全球范围内面临着迅速减少的问题。利用全面的地理和基因组采样,结合 DNA 与环境和气候数据集的整合方法,我们评估了现存四个鲎物种中三个物种的种群遗传结构、人口历史以及对未来气候变化的脆弱性,这些物种都集中在亚洲。我们的研究强调,巽他陆架是一个复杂多变的浅海地貌,是所有三个亚洲物种遗传多样性的唯一宝库,因此对鲎的长期生存至关重要。我们的研究不仅为评估亚洲鲎的保护状况提供了第一个基因组基线数据,而且还确定了在即将到来的人为全球变暖中可能成为亚洲鲎种群避难所和走廊的核心栖息地。
期刊介绍:
Conservation Letters is a reputable scientific journal that is devoted to the publication of both empirical and theoretical research that has important implications for the conservation of biological diversity. The journal warmly invites submissions from various disciplines within the biological and social sciences, with a particular interest in interdisciplinary work. The primary aim is to advance both pragmatic conservation objectives and scientific knowledge. Manuscripts are subject to a rapid communication schedule, therefore they should address current and relevant topics. Research articles should effectively communicate the significance of their findings in relation to conservation policy and practice.
