Abstract When recovery goals for threatened and endangered species have been reached, these species will be removed from lists of threatened species. The self-sustainability of delisted species depends on both demographic and genetic factors, while genetic factors are still not considered as an essential part of evaluation in delisting decisions. In this study, we checked if genetic factors were less considered than demographic characters in delisting decisions and the following post-delisting monitoring plans (PDMPs). We found that only 32.76% (19 of 58 decisions) delisting decisions contained genetic factors, with genetic variation being the most frequently mentioned genetic factor, whereas all delisting decisions considered demographic characters. Moreover, we detected an increasing trend of genetic factors being considered in delisting decisions over time, but this may just be the result of more available genetic data produced by conservation studies rather than a rising awareness of the importance of genetic factors in policy making of delisting decisions. Genetic factors were also overlooked in PDMPs with only two out of 29 PDMPs monitoring genetic factors. As the rapid development of conservation genomics, we addressed the application value of genomic data in delisting decisions and proposed a candidate genetic criterion that effective population size should be greater than 1000 to assess the successful recovery of an endangered species and self-sustainability of delisted species.

在退市物种中，遗传因素比人口统计特征考虑得少

摘要 当受威胁和濒危物种的恢复目标达到时，这些物种将从受威胁物种名单中删除。被除名物种的自我可持续性取决于人口和遗传因素，而遗传因素仍然不被视为除名决定评估的重要组成部分。在这项研究中，我们检查了在退市决定和以下退市后监测计划 (PDMP) 中是否比人口特征少考虑遗传因素。我们发现只有 32.76%（58 个决定中的 19 个）的退市决定包含遗传因素，遗传变异是最常提到的遗传因素，而所有退市决定都考虑了人口统计学特征。而且，随着时间的推移，我们发现在除名决定中考虑遗传因素的趋势越来越大，但这可能只是保护研究产生的更多可用遗传数据的结果，而不是人们越来越意识到遗传因素在除名决定决策中的重要性。PDMP 中也忽略了遗传因素，29 个 PDMP 中只有两个监测遗传因素。随着保护基因组学的快速发展，我们针对基因组数据在退市决策中的应用价值提出了有效种群规模大于1000的候选遗传标准，以评估濒危物种的成功恢复和退市物种的自我维持能力. 但这可能只是保护研究产生的更多可用遗传数据的结果，而不是人们越来越意识到遗传因素在除名决定的政策制定中的重要性。PDMP 中也忽略了遗传因素，29 个 PDMP 中只有两个监测遗传因素。随着保护基因组学的快速发展，我们针对基因组数据在退市决策中的应用价值提出了有效种群规模大于1000的候选遗传标准，以评估濒危物种的成功恢复和退市物种的自我维持能力. 但这可能只是保护研究产生的更多可用遗传数据的结果，而不是人们越来越意识到遗传因素在除名决定的政策制定中的重要性。PDMP 中也忽略了遗传因素，29 个 PDMP 中只有两个监测遗传因素。随着保护基因组学的快速发展，我们针对基因组数据在退市决策中的应用价值提出了有效种群规模大于1000的候选遗传标准，以评估濒危物种的成功恢复和退市物种的自我维持能力.
