Salmon runs are an important time when salmon migrate from the ocean to freshwater, swimming upriver to reach spawning beds. These annual events provide an important food source for both predators and for local communities. However, Recent declines in salmon runs have caused hardship in subsistence fishing communities throughout Alaska, particularly in the Yukon River Basin. To adapt to a changing climate, fishing communities, natural resource managers, and scientists need to measure and understand climate impacts onto salmon runs in this region. To monitor changes in salmon populations and manage fisheries, the Alaska Department of Fish and Game (ADFG), U.S. Fish and Wildlife Service (USFWS), and Tanana Chiefs...

Ecosystems spanning the zones from “ridge-to-reef" and “icefield-to-ocean” are home to relatively high levels of biodiversity; serve as conduits of nutrients to sensitive coastal environments; and are culturally and economically important to local communities. These systems are smaller and have unique geological and streamflow properties compared to more typical river systems and, because of this, it is not clear how they will respond to shifting climatic patterns. Both Hawaiian ridge-to-reef and Alaskan icefield-to-ocean ecosystems face the potential of climate-driven changes in extreme flow events, such as floods and droughts, that could dramatically change how critical nutrients are retained and transported....
