Indicative distribution map for Ecosystem Functional Group M1.10 Rhodolith/Maërl beds

This archive contains indicative distribution maps and profiles for M1.10 Rhodolith/Maërl beds, a ecosystem functional group (EFG, level 3) of the IUCN Global Ecosystem Typology (v2.1). Please refer to Keith et al. (2020) and Keith et al. (2022) for details. The descriptive profiles provide brief summaries of key ecological traits and processes, maps are indicative of global distribution patterns, and are not intended to represent fine-scale patterns. The maps show areas of the world containing major (value of 1, coloured red) or minor occurrences (value of 2, coloured yellow) of each ecosystem functional group. Minor occurrences are areas where an ecosystem functional group is scattered in patches within matrices of other ecosystem functional groups or where they occur in substantial areas, but only within a segment of a larger region. Given bounds of resolution and accuracy of source data, the maps should be used to query which EFG are likely to occur within areas, rather than which occur at particular point locations. Detailed methods and references for the maps are included in the profile (xml format).本存档包含M1.10 藻砾床/红藻礁床（Rhodolith/Maërl beds）的示意性分布图与概况文档，该类群属于世界自然保护联盟（International Union for Conservation of Nature, IUCN）全球生态系统分类体系（v2.1）中的3级生态系统功能群（Ecosystem Functional Group，简称EFG）。详细信息请参阅Keith等人（2020）与Keith等人（2022）的研究成果。 本概况文档对核心生态特征与生态过程进行了简要概述；分布图仅用于展示全球分布格局，并非用于呈现精细尺度的分布特征。本分布图标注了全球范围内该生态系统功能群的主要分布区（取值为1，以红色标注）与次要分布区（取值为2，以黄色标注）。其中，次要分布区指该生态系统功能群以斑块形式零散分布于其他生态系统功能群的群落基质中，或仅在大区域的局部范围内形成连片分布的区域。鉴于源数据的分辨率与精度存在限制，本分布图仅应用于查询某一区域内可能存在的该生态系统功能群，而非特定点位的分布情况。本分布图的详细编制方法与参考文献均收录于概况文档（格式为XML）中。
