Terrestrial Mollusks of Attu, Aleutian Islands, Alaska

ABSTRACT. Seven species of land mollusk (2 slugs, 5 snails) were collected on Attu in July 1979. Three are circumboreal species, two the fauna was assembled overwater since deglaciation, perhaps within the last 10 OOO years. Mollusk faunas from Kamchatka to are amphi-arctic (Palearctic and Nearctic...

Seven species of land mollusk (2 slugs, 5 snails) were collected on Attu in July 1979. Three are circumboreal species, two the fauna was assembled overwater since deglaciation, perhaps within the last 10 OOO years. Mollusk faunas from Kamchatka to are amphi-arctic (Palearctic and Nearctic but not circumboreal), and two are Nearctic. Barring chance survival of mollusks in local refugia, southeastern Alaska all have a Holarctic component. A Palearctic component present on Kamchatka and the Commander Islands is absent from the Aleutians, which have a Nearctic component that diminishes westward. This pattern is similar to that of other soil-dwelling invertebrate groups.
