Source pool diversity and proximity shape the compositional uniqueness of insular mammal assemblages worldwide

Site by species matrices of the presence/absence of non-volant terrestrial mammals on a total of 204 islands in 9 different island groups. These island groups are as follows: Alexander Archipelago (Alx), Gulf of California (Clf), Mediterranean Land-bridge (MdtLB), Mediterranean Oceanic (MdtOC), Adriatic Sea (Adr), Philippines (Phl), Sundaland (Snd), Maluku islands (Mlk), Melanesia (Mln). Island names are in rows, and species names are in columns. A value of 0 indicates absence, and a value of 1 indicates presence. This data was compiled using published records in the primary literature, archipelago-wide checklists, and atlases, and cross-referenced community composition among multiple sources (Table S1 in the associated article). Domesticated and introduced species were omitted when indicated as non-native in the source data or the IUCN Red List.

本数据集为涵盖9个不同岛屿群共计204个岛屿的陆生非飞行哺乳动物存在/缺失情况的样点-物种矩阵。涉及的9个岛屿群如下：亚历山大群岛(Alx)、加利福尼亚湾(Clf)、地中海陆桥群岛(MdtLB)、地中海大洋群岛(MdtOC)、亚得里亚海(Adr)、菲律宾群岛(Phl)、巽他古陆(Snd)、马鲁古群岛(Mlk)、美拉尼西亚群岛(Mln)。该矩阵以岛屿名称为行名，物种名称为列名，其中数值0代表对应物种未在该岛屿出现，数值1代表对应物种存在于该岛屿。本数据集基于原始文献、群岛全域物种名录及区域图集的公开记录汇编而成，并通过多来源的群落组成数据进行交叉验证（相关论文附表S1）。若源数据或国际自然保护联盟红色名录（IUCN Red List）标注某物种为非本土物种，则该驯化或外来引入物种将被排除出本数据集。
