High latitude northern ecosystems are currently warming twice as fast as the global average. Over the last several decades, this has caused dramatic losses of frozen area in the Arctic and sub-Arctic. However, it is unclear how melting coastal mountain glaciers, thawing permafrost, and declines in snowpack will affect the quality of freshwater habitat for culturally and economically important salmon in Alaska. As a collaborative effort with the Alaska Department of Fish and Game, the Alaska Department of Natural Resources, and the U.S. Fish and Wildlife Service, this project aims to answer three questions: How does melting affect the freshwater habitat of Pacific salmon? How will changes to aquatic flows...

In ecosystems characterized by flowing water, such as rivers and streams, the dynamics of how the water moves - how deep it is, how fast it flows, how often it floods - have direct effects on the health, diversity, and sustainability of underlying communities. Yet increasingly, climate extremes like droughts and floods are disrupting fragile stream ecosystems by specifically changing their internal aquatic flows. Human infrastructure, such as irrigation and dams, further disrupt these dynamics. These changes in climate and land use are leading to teh fragmentation of aquatic habtiat, degraded water quality, altered sediment transport processes, variation in the timing and duration of floodplain inundation, shifts...
