  • Distribution and habitat use of bull trout following the removal of nonnative brook trout

    Creator:
    Renner, Dirk
    Abstract:
    Invasion by nonnative brook trout (Salvelinus fontinalis) often results in replacement of bull trout (Salvelinus confluentus) in western North America, but the causal mechanisms are not well understood. Removal of brook trout from 1992 to 2000 from Sun Creek in southern Oregon, provided an opportunity to investigate the changes in...
