Mammals, reptiles and crabs on the Krakatau Islands: Their roles in the ecosystem
Abstract In 1982 I studied the changes which had taken place in the fauna of the Krakatau Islands over the last fifty years, and elucidated the roles of terrestrial consumers and reducers in the developing ecosystems of these islands. Only two species of rat were found ( Rattus rattus and R. tiomani...
