  abstract = {{B}rown trout {S}almo trutta {L}innaeus, 1758, is a priority species for conservation and management efforts in many {E}uropean countries. {I}n its native range, interactions with non-native fishes often adversely affect somatic growth rates and population abundances. {C}onsequences of introduced {N}orth {A}merican pumpkinseed {L}epomis gibbosus ({L}innaeus, 1758) for native {S}. trutta were examined in stream stretches with and without {L}. gibbosus. {D}ata for somatic growth rates and trophic niche breadth (using stable isotope analyses) provided little evidence of {L}. gibbosus presence being detrimental for {S}. trutta. {S}hifts in {S}. trutta diet at all sites were associated with increased piscivory with increasing body length, with no evidence to suggest that interspecific resource competition with {L}. gibbosus structured the food web or affected trophic positions. {T}hree years later, and following {L}. gibbosus removal, data revealed slight shifts in the food web at each site, but these related to shifts in resources at the bottom of the food chain rather than a response to {L}. gibbosus removal. {C}onsequently, the ecological consequences of {L}. gibbosus for {S}. trutta in the study stream were minimal, with {S}. trutta populations responding more to natural mechanisms regulating their populations than to the presence of this non-native fish species.},
