“…Because far more rainbow trout were stocked in Buffalo Bill Reservoir than into the North Fork Shoshone River and its tributaries directly, we also calculated distance from each sampling site to the confluence of the North Fork Shoshone River with Buffalo Bill Reservoir, using NHDPlusV2 river shapefiles for this basin (National Hydrography Data set; McKay et al, ) and the riverdist package in R (Tyers, ), and used this distance as a predictor variable in our models. Previous studies of introduced rainbow trout suggest that many individuals remain close to their stocking location, but a subset disperse (Bennett et al, ; Cresswell & Williams, ) and several studies suggest that distance from stocking locations of introduced rainbow trout can influence hybridization outcomes with cutthroat trout, or use indices of propagule pressure that include distance to quantify rainbow trout stocking (Bennett et al, ; Gunnell, Tada, Hawthorne, Keeley, & Ptacek, ; Muhlfeld et al, ).…”
