Snails on islands

Snails on islands

Presentation by Cristian R. Altaba (EvoCog, University of the Balearic Islands, and Llevant Natural Park, Govt. of the Balearic Islands), with Q&A period

Description: Land snails are present on virtually all islands, often with extreme levels of endemism, very small species ranges and remarkable diversification within archipelagos and single islands. Taxonomic traditions are a cumbersome problem for establishing comparisons across different regions, yet it is clear that island age and ecological diversity are relevant ingredients in the building of snail faunas. Insular snails are experiencing a mass extinction worldwide, apparently more intense than on any continental area. It is thus relevant and timely to ask whether the evolution of terrestrial gastropods has anything special on island ecosystems. Archipelagos located around Africa show snail island faunas differ from equivalent continental assemblages. A comparison with other insular molluscan communities worldwide provides a general framework to highlight the peculiar tempo and mode of snail evolution on islands.
