Benthic Community Structure and Invertebrate Drift in a Pacific Island Stream,Kosrae, Micronesia1
Authors:James G March  Jonathan P Benstead  Catherine M Pringle  Marston Luckymis
Abstract:Tropical Pacific island streams have poorly understood communities that deserve scientific attention. We examined benthic macroinvertebrates and fishes of the Inem River on Kosrae, Federated States of Micronesia. Larval chironomids, lepidopterans, odonates, and freshwater shrimps dominated the benthos and drift. Diel periodicity in drift was not evident. Nine fishes, two shrimps, and one snail species were identified. Kosrae's stream fauna appears even more depauperate than other Pacific high islands, possible due to its extreme isolation.
