Marine-derived nutrients from Pacific salmon are transferred to streams and riparian forests through diverse food web pathways. Researchers quantified the influence of salmon on the abundance and composition of songbird communities across a wide range of salmon-spawning biomass on 14 streams along a remote coastal region of British Columbia. They show that bird abundance and diversity increase with salmon biomass and that watershed size and forest composition are less important predictors.
