The use of feathers in monitoring bioaccumulation of metals and metalloids in the South African endangered African grass-owl (Tyto capensis)

Autor: T. M. Ansara-Ross, M. J. Ross, Victor Wepener

Publikováno v: Ecotoxicology. 22:1072-1083

Few studies have quantified metals in South African species and no published data on residues specifically in South African owl feathers exist. Tyto capensis is listed as vulnerable within South Africa, making it preferable to use a non-invasive tech
