Armbruster receives grant to study the fish fauna in Guyana
Jonathan Armbruster, of the Department of Biological Sciences, received a grant from the Coypu Foundation Trust to study the fish fauna of the upper Ireng River in Guyana, a country in Northern South America formerly known as British Guiana. Armbruster is currently studying when fishes moved into or became isolated within the high Pakaraima Mountains and the diversity of fishes there. The rivers draining the Pakaraima Mountains fall off the plateau resulting in waterfalls like the 740-foot Kaieteur Falls. The waterfalls separate the lowland and upland fauna into distinct biotas. Auburn researchers, together with faculty at the Royal Ontario Museum, first began studying the fishes and Pakaraima Mountains of Guyana in 1998 following a National Geographic sponsored trip.
