<b>Continent-wide analysis of moss diversity in Antarctica</b>

This study focused on investigating diversity patterns of moss diversity in Antarctica, a key taxa in local ecosystems. Limited understanding of diversity patterns and conservation efficacy prompted our investigation.This dataset includes the following items:<i>AntarcticMoss_species_with_notes.xlsx</i>: species list organised by genus, family order; species autorithy; and notes.<i>moss_species_coordinates.csv</i>: point records of Antarctica mosses (species name, and coordinates)<i>species_presence_matrix_ACBR.csv</i>: presence-absence matrix of moss presence across Antarctic Conservation Biogeographic Regions (ACBR).<i>species_presence_matrix_ASPA_final.csv: </i>presence-absence matrix of moss presence across Antarctic Specially Protected Areas (ASPA).<i>Scripts.zip</i>: R script to runs analysis for diversity patterns (richness, beta- and zeta-diversity), range size frequency, environmental drivers of richness, and representation/redundancy.<i>eq_rigri_richness_moss_10x10km.tif</i>: raster file of moss richness in Antarctica at 10 x 10 km resolution<br>

本研究聚焦于南极洲苔藓的多样性分布格局，苔藓是当地生态系统中的关键类群。此前学界对其多样性分布格局与保护成效的认知较为有限，因此开展本次调查。本数据集包含以下内容：
<i>AntarcticMoss_species_with_notes.xlsx</i>：按属、科分类阶元整理的物种名录、物种命名人及相关注释；
<i>moss_species_coordinates.csv</i>：南极洲苔藓物种的点位记录，包含物种名称与坐标信息；
<i>species_presence_matrix_ACBR.csv</i>：南极洲保护生物地理区域（Antarctic Conservation Biogeographic Regions, ACBR）内苔藓物种的有无矩阵；
<i>species_presence_matrix_ASPA_final.csv</i>：南极洲特别保护区（Antarctic Specially Protected Areas, ASPA）内苔藓物种的有无矩阵；
<i>Scripts.zip</i>：用于开展多样性格局（物种丰富度、β多样性与ζ多样性）、分布区大小频率、物种丰富度的环境驱动因子以及表征与冗余度分析的R脚本；
<i>eq_rigri_richness_moss_10x10km.tif</i>：分辨率为10×10千米的南极洲苔藓物种丰富度栅格文件。
