Abstract
Sympatric populations of Salvelinus malma and Salvelinus alpinus from Karluk and Fraser Lakes, Kodiak Island, Alaska, were compared using the discriminant function analysis. The analysis indicated that hybridization between S. malma and S. alpinus rarely, if ever, occurs in these lakes. Therefore, S. malma and S. alpinus are considered distinct species. Data on 507 S. malma and 411 S. alpinus from 77 localities suggest at least two distinct forms of both S. malma and S. alpinus in North America. Speculations are made on the origin and evolution of S. malma and S. alpinus.
