Evolution, Ecology, and Conservation of Dolly Varden, White spotted Char, and Bull Trout
Abstract We review the ecology and conservation of three lesser‐known chars (genus Salvelinus ): Dolly Varden ( S. malma ), white‐spotted char ( S. leucomaenis ), and bull trout ( S. confluentus ). Dolly Varden is distributed across the northern Pacific Rim and co‐occurs with bull trout and white‐sp...
