The introduction of non-native species into aquatic environments has been linked with local extinctions and altered distributions of native species. We investigated the effect of non-native salmonids on the occupancy of two native amphibians, the long-toed salamander (Ambystoma macrodactylum) and Columbia spotted frog (Rana luteiventris), across three spatial scales: water bodies, small catchments and large catchments.

Keywords: Ambystoma macrodactylum, amphibian decline, biological invasions, fish stocking, landscape, mountain lake, Rana luteiventris
