Clinton Factheu is a Ph.D. student in the Department of Animal Biology and Physiology at the University of Yaoundé I (Cameroon). His project focuses on the use of passive acoustics to assess the impact of the giant salvinia on the African manatee’s habitat use in Lake Ossa. Giant salvinia is an exotic, free-floating aquatic fern that has invaded approximately 25% of the lake, which is considered a manatee sanctuary in Cameroon. Clinton deploys hydrophones in the lake to compare the African manatee’s occurrence patterns in invaded versus non-invaded areas. Results of his project will help direct manatee conservation efforts in the Lake Ossa Wildlife Reserve.
