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.
