Brook Stickleback Culaea inconstans is an aquatic invasive species in Wyoming that may pose a risk to native biodiversity. Our aim was to evaluate the current risk Brook Stickleback poses to native fish species in the North Platte River drainage. We updated the current distribution of Brook Stickleback, evaluated for possible range expansion, and determined landscape-level habitat drivers and occupancy potential for streams across the North Platte River drainage. Data included in this release was used to 1: run a random forest classification model to determine Brook Stickleback habitat associations in lotic environments at the landscape scale, 2. to determine habitat suitability across the study area based on predicted...

Trophic studies can provide valuable information on the risk an invader poses to native species. Brook Stickleback Culaea inconstans is an invasive fish species in Wyoming whose effect on native fish assemblages is poorly understood. Our goal was to understand the potential for competitive interactions between Brook Stickleback and native fishes. We used stable isotopes of carbon (ẟ13C) and nitrogen (ẟ15N) to evaluate the feeding ecology of Brook Stickleback relative to four native fishes. The data are appropriate for exploring whether native fish isotopic niches changed in sympatry with Brook Stickleback and to evaluate niche overlap between native fishes and Brook Stickleback. The data are associated with the...
