摘要:

定期开展物种红色名录评估, 了解植物濒危状态、致危因素变化, 对于物种保育有重要意义。本文报道了国产裸子植物的最新评估结果, 并与2013版红色名录进行了比较。本次评估了国产裸子植物274个种和种下分类群(隶属于8科37属)。与2013版红色名录相比, 本次评估减少了2科, 增加了3属和40个种和种下分类群。分类群变化是由于上次评估遗漏属种、新类群、新分布记录以及分类群名称和等级变化所致。本次评估有139个种和种下分类群被列入受威胁等级(包括极危、濒危和易危), 占总评估种类的50.7%, 与2013版的51.0%相比, 受威胁程度基本不变。物种自身进化属性、资源过度利用、生境丧失和全球变暖是国产裸子植物的主要致危因素。此外, 还有27种列为数据缺乏(DD), 占总种数的9.9%, 较2013版略有增加, 表明我国裸子植物需开展针对性野外调查和相关研究, 以摸清物种的野外生存现状, 为深入认识我国裸子植物濒危程度奠定数据基础。新的红色名录评估对濒危物种保育实践也有重要意义。

Abstract

Aims: It is important to conduct periodical red list assessments, understand the threatened status and threats, for effective species conservation. Here we report a new red list assessment of gymnosperm species native to China with a comparison between this new assessment and the earlier assessment released in 2013.
Methods: We collected species data from published references and databases and adopted the IUCN Red List Categories and Criteria ver. 3.1 for the red list assessment.
Results: This new red list assessment of gymnosperms includes 274 species and infraspecies, belonging to 37 genera and 8 families, all of which are native to China. Compared with the red list version released in 2013, 2 families were reduced in priority, while 3 genera and 40 species and infraspecies increased in priority during this study. These changes are caused by updating recent taxonomic novelties and adding a few taxa missing in the previous assessment. Among the 274 assessed specific and infraspecific taxa, 139 were listed as threatened (including Critically Endangered (CR), Endangered (EN), and Vulnerable (VU)). Of the total assessed species, up to 50.7% are listed as threatened, which is similar to the proportion of the previous assessment. In addition, there are 27 species and infraspecies listed as Data Deficient (DD), approximately 9.9% of the total assessed species.
Conclusions: Threats to Chinese gymnosperm species include internal attributes of relic and endemic species, over-exploitation, habitat loss, and global warming. The high ratio of Data Deficient (DD) species suggests that it is necessary to conduct targeted field investigations to better understand the living status and threats of gymnosperms in China in order to lay a solid foundation for the next red list assessment. The new assessment will be helpful to guide conservation practices of Chinese gymnosperms.
