Abstract (from http://onlinelibrary.wiley.com/doi/10.1111/eff.12084/abstract): Smallmouth bass (Micropterus dolomieu, SMB) is a broadly distributed, economically important species in the USA and Canada. Although previous research has suggested that projected climate warming may allow SMB to thrive beyond their current northern distribution, little research has been devoted to the population-level effects of climate change on warm-water fishes, including SMB. We modelled the impacts of projected climate change on growth of stream-dwelling SMB along a north–south gradient in the central USA. Using downscaled regional projections from three global climate models, we generated scenarios for thermal habitat change for four populations (in [...]
