Aphids and associated natural enemies on Ile Amsterdam and Ile Saint-Paul, Southern Indian Ocean
Abstract Ile Amsterdam (37°50′S, 77°30′E, 55 km 2 ) and Ile Saint-Paul (38°43′S, 77°31′E, 7 km 2 ) are very isolated volcanic islands which were originally colonized by a few invertebrate fauna and flora. Invasive species richness has then increased along with human activity. A three-year monitoring...
