We propose to develop a Yukon-Kuskokwim Berry Outlook: a data- and observer-driven ecological monitoring and modeling framework that forecasts changes in berry habitat and abundance with climate and environmental change. Berry-producing plants are extremely important to human and wildlife communities of the Yukon-Kuskokwim (Y-K) Delta. Berry yield can be influenced by snow cover, rainfall, soil moisture, air temperature, availability of insect pollinators, and seasonal weather extremes; and berry habitat can be altered by more frequent tidal inundation, increased frequency of storm surges, and permafrost deterioration, all of which may be significantly impacted by climate change. In a recent survey of Alaskan environmental...

Future of Aquatic Flows: Impacts of Cryospheric Change on Aquatic Flows and Freshwater Habitat Quality for Fish and Communities
High latitude northern ecosystems are currently warming twice as fast as the global average. These temperature increases over the last several decades have led to dramatic declines in the terrestrial cryosphere in Arctic and sub-Arctic ecosystems, through the melting of coastal mountain glaciers, thawing of permafrost, and changes in snowpack.. Therefore, characterizing freshwater habitat for salmonfish in Alaska is becoming an increasingly important component of watershed management in light of rapid environmental changes across the Arctic and sub-Arctic. This project proposes a highly collaborative effort among a variety of state agencies, federal agencies and non-profit organizations focused on three overarching...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete.
