对海洋无脊椎动物物种灭绝风险的评估仍然很少，这阻碍了在人类活动影响下对海洋生物多样性进行有效管理。为了帮助缩小这一信息差距，在本文中，我们提供了一个度量的相对灭绝风险相结合的古生物学数据，灭绝率从化石记录计算的形式，在现代的风险与两个已知的相关性：地理范围的大小和实现的热生态位。我们测试的性能，这个公制古生物灭绝风险的血统（危险）-生存分析上新世双壳动物群从加州和新西兰，然后用它来确定当今的热点灭绝脆弱性现存的浅海双壳类。在海洋区域，如果双壳类物种集中，危险指数较高，同时气候或人为压力因素也很高，则应将其视为养护和管理方面最紧迫的问题。
Extinction risk assessments of marine invertebrate species remain scarce, which hinders effective management of marine biodiversity in the face of anthropogenic impacts. To help close this information gap, in this paper we provide a metric of relative extinction risk that combines palaeontological data, in the form of extinction rates calculated from the fossil record, with two known correlates of risk in the modern day: geographical range size and realized thermal niche. We test the performance of this metric-Palaeontological Extinction Risk In Lineages (PERIL)-using survivorship analyses of Pliocene bivalve faunas from California and New Zealand, and then use it to identify present-day hotspots of extinction vulnerability for extant shallow-marine Bivalvia. Areas of the ocean where concentrations of bivalve species with higher PERIL scores overlap with high levels of climatic or anthropogenic stressors should be considered of most immediate concern for both conservation and management.
