Taxon-level assessment of the data collection quality in Atlas Florae Europaeae: insights from the case of Rosa (Rosaceae) in Eastern Europe

By the method of data re-collection and re-assessment, we tested the completeness of distribution areas of the species and species aggregates of Rosa in Eastern Europe as mapped in volume 13 of Atlas Florae Europaeae, and discussed insights into the issues connected with the data. We have found many new occurrences which are additions to the published maps: 1068 records of species and 570 records of species aggregates. The new occurrences are listed with references to the sources, and the updated AFE maps are provided. The greatest increase by new native occurrences was revealed for the species that are widespread or taxonomically complicated, and by new alien occurrences for the species that expand their secondary distribution areas. The mapping work published in 2004 is considered good, with minor omissions caused by possible oversights and incomplete sampling. The majority of new additions originated in the period after the original data collection. Nearly the same amount of new data...本研究采用数据重新采集与重新评估的方法，对《欧洲植物志图集》（Atlas Florae Europaeae）第13卷中绘制的东欧蔷薇属（Rosa）物种及物种聚合群的分布区完整性进行了检验，并针对该数据集相关问题展开了深入探讨。本次研究共发现大量可补充至已发布分布图的新分布记录：其中物种分布记录1068条，物种聚合群分布记录570条。上述新分布记录均标注了数据来源，同时附带了更新后的《欧洲植物志图集》（AFE）分布图。新增本土分布记录增幅最大的类群为广布物种或分类学复杂物种，而新增外来分布记录增幅最大的则为正在扩张次生分布区的物种。2004年发布的制图工作质量良好，仅存在少量因潜在疏漏与采样不完整导致的细微遗漏。绝大多数新增分布记录均来自原始数据采集之后的时段，新增数据的数量几乎与……持平。
