From: Warming Alaskan rivers affect first-year growth in critical northern food fishes
River basin average summer temperatures increase from historical to future mid-century scenarios across the Arctic-Yukon-Kuskokwim (AYK) region. Lighter colors represent colder areas that could provide thermal refugia for cold-water fishes under warming scenarios. Maps of river basins and their respective average temperatures from (a) historical (1990–2021) and (b) future mid-century (2034–2065) pseudo-global warming (PGW) scenarios (Blaskey et al., 2024b). Maps were generated in Python version 3.12.2 ( https://docs.python.org/release/3.12.2/) using river network geopackages from MERIT Hydro49 and Cartographic Boundary shapefiles for the state of Alaska50.
