Disequilibrial island turnover dynamics: a 17‐year record of Bahamian ants
Abstract Aim To document long‐term rates of immigration, extinction and turnover in insular ant faunas and evaluate the relative impacts of recent hurricane activity and climate change. Location Small islands in the Exuma Cays, Andros and Abaco archipelagos of the Bahamas. Methods I surveyed the ant...
