摘要

摘要简介苔藓植物的基本记录包括编制一份在实地考察中发现的简单物种清单。这项研究的目的是调查这些记录作为保护区状况变化证据的价值。方法研究区域包括英国埃平森林,自1800年以来,该森林一直在临时进行苔藓植物的基本记录,并于2022年1月再次进行。共有224个物种被纳入分析范围,每个物种都被归类为在2022年1月的调查中发现的或仅在之前的记录中发现的。每个物种的艾伦伯格指示值来源于已发表的文献。为了调查艾伦伯格指标中是否有任何一个是2022年1月调查期间是否发现一个物种的重要预测因素,构建了一个二项式广义线性模型(模型1)。产生了第二个类似的模型,该模型排除了附生植物(模型2)。结果关于在2022年1月发现一个物种的可能性,模型1表明,它与湿度和酸度呈高度显著的负相关,与氮呈高度显著正相关。模型2提供了类似的结果,只是水分不显著。结论基本苔藓植物记录表明,埃平森林的状况发生了显著变化,成为一个酸性较弱、营养丰富的地区。这与已知的二氧化硫污染的减少和硝化作用的增加是一致的。

How basic bryophyte recording provides information on major changes in key conservation localities: a case study of Epping Forest, England, an internationally significant site
ABSTRACT Introduction Basic recording of bryophytes involves compiling a simple list of species found during a site visit. The aim of this study was to investigate the value of such records as evidence of change in the condition of protected areas. Methods The study area comprised Epping Forest, UK, where basic bryophyte recording has been undertaken ad hoc since ca 1800 and was again carried out in January 2022. A total of 224 species were included within the analysis, each categorised as either having been found during the surveys in January 2022 or only found during previous recording. Ellenberg indicator values for each species were derived from published literature. To investigate if any of the Ellenberg indicators were significant predictors of whether or not a species was found during the January 2022 surveys, a binomial generalised linear model was constructed (model 1). A second similar model was produced that excluded epiphytes (model 2). Results Regarding the likelihood of a species having been found during January 2022, model 1 indicated that there were highly significant negative relationships with moisture and acidity, and a highly significant positive relationship with nitrogen. Model 2 provided similar results except that moisture was insignificant. Conclusions Basic bryophyte records indicated that the condition of Epping Forest has undergone significant change, to become a site that is less acidic and more nutrient rich. This is consistent with a known decline in sulphur dioxide pollution and an increase in nitrification.

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.
