Abstract

ABSTRACT Introduction Britain supports one of the richest bryophyte floras in Europe. Following previous assessments in 2001 and 2011, the aim of this study was to provide a new IUCN Red List of the bryophytes of Britain. Methods Following IUCN guidance, all species known to have occurred in Britain since ad 1500 (n = 1097) were assessed based on a comprehensive review and synthesis of available information. Various new measures are provided here for all species, such as the number of subpopulations, area of occupancy, and extent of occurrence, in addition to national population estimates for 181 species. Results are compared with the previous Red List assessment of 2011. Key results and conclusions Species were categorised as Regionally Extinct (RE, n = 4), Not Applicable (NA, n = 23), Data Deficient (DD, n = 45), Critically Endangered (CR, n = 59), Endangered (EN, n = 52), Vulnerable (VU, n = 80), Near Threatened (n = 39) or Least Concern (n = 795). Excluding those in DD, NA or RE, 19% (n = 191) of bryophyte species in Britain are threatened with extinction (i.e. are in CR, EN or VU). Of the 59 species in the highest extinction risk category (CR), it is possible that 20 (34%) are already extinct. Of the 143 species included in the previous assessment in a threatened category (CR, EN or VU), 85 (69%) have been transferred to a new category, mainly because of new information on the status of the species.
世界自然保护联盟新的英国苔藓植物红色名录,2023年
摘要简介英国拥有欧洲最丰富的苔藓植物区系之一。根据2001年和2011年的评估,本研究的目的是提供一份新的英国苔藓植物国际自然保护联盟红色名录。方法根据世界自然保护联盟的指导,对自公元1500年以来已知在英国发生的所有物种(n = 1097)进行了评估。除了181个物种的全国种群估计外,这里还为所有物种提供了各种新的衡量标准,如亚种群数量、占用面积和发生程度。结果与2011年之前的红名单评估结果进行了比较。主要结果和结论物种被归类为区域灭绝(RE,n = 4) ,不适用(NA,n = 23),数据不足(DD,n = 45),极度濒危(CR,n = 59),濒危(EN,n = 52),易受攻击(VU,n = 80),近危(n = 39)或最不关心(n = 795)。不包括DD、NA或RE,19%(n = 191)的苔藓植物物种面临灭绝的威胁(即在CR、EN或VU)。在最高灭绝风险类别(CR)的59个物种中,可能有20个(34%)已经灭绝。在之前的评估中被列入受威胁类别(CR、EN或VU)的143个物种中,85个(69%)已被转移到新的类别,主要是因为有关该物种状况的新信息。

期刊介绍: Journal of Bryology exists to promote the scientific study of bryophytes (mosses, peat-mosses, liverworts and hornworts) and to foster understanding of the wider aspects of bryology. Journal of Bryology is an international botanical periodical which publishes original research papers in cell biology, anatomy, development, genetics, physiology, chemistry, ecology, paleobotany, evolution, taxonomy, molecular systematics, applied biology, conservation, biomonitoring and biogeography of bryophytes, and also significant new check-lists and descriptive floras of poorly known regions and studies on the role of bryophytes in human affairs, and the lives of notable bryologists.
