Management of whale shark Rhincodon typus populations is hampered by a lack of information on the range travelled by individual whale sharks. This applies particularly in South-east Asia where the whale shark is increasingly used in commercial trade and for ecotourism. In this study an investigation of the movements of individual whale sharks from the greater Sulu Sea region was initiated using satellite telemetry. The movements of six sharks were monitored from 7 to 128 days. Two sharks travelled distances of 4567 and 8025 km. Both sharks moved through multiple political jurisdictions, con®rming the need to manage the populations on a multilateral or regional level.
The Philippine spotted deer Cervus alfredi, endemic to the Visayan Islands, is threatened by deforestation and hunting. Already extinct over 95 per cent of its former range, populations survive probably only in Panay and Negros. In 1987 a conservation programme was drawn up with two immediate objectives: to establish a national park in west Panay and to embark on a captive-breeding programme. The authors describe the operation of the project and its progress to date, and discuss plans for its extension.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
