Alaska's Changing Habitats: A Multi-System Approach for Understanding Climate Impacts in High Latitude Regions

Scientific information can be used to help individuals, communities, and governments alike make more informed decisions. However, for people to become aware of the science that could inform their decisions and its relevance to their lives and decisions, it must be communicated effectively. Multiple obstacles prevent this from happening, including scientists’ lack of time and communication expertis

Understanding Ridge-to-Reef and Icefield-to-Ocean Ecosystem Function in a Changing Climate

Steep, mountainous watersheds, dramatic climate gradients, and tight links between the land and sea are common features of both the Pacific Islands and Southeast Alaska. In these "ridge-to-reef" and “icefield-to-ocean" ecosystems, environmental changes that occur at higher elevations have downstream impacts on the waters below. Today, these two ecosystems are undergoing changes in climate that are

Building a Coastal Flood Hazard Assessment and Adaptation Strategy with At-Risk Communities of Alaska

Coastal flooding and erosion caused by storms and sea-level rise threaten infrastructure and public safety in Alaska Native communities. Though the problem is well known, there are few tools that can assess local vulnerability to coastal flood hazards. Even fewer tools can be customized with specific community information to support local adaptation planning. The main goal of this project is t

Building Tribal Capacity to Adapt and Respond to Climate Change in Southeast Alaska

Climate adaptation planning provides a framework for Tribes to exercise sovereignty over wild resources important for the subsistence way of life and economic and cultural activities that are being impacted by climate change. The climate adaptation planning process includes identifying key resources that are currently being impacted by climate change, or that may be impacted in the future, as well

Co-producing Climate Research and Adaptation through Partnerships with Alaska Native Communities

Climate change is impacting the land and resources that Alaska Native peoples rely on for food security, resource management, and cultural continuity. In Southeast Alaska, communities face increased weather variability due to climate change, which impacts subsistence food resources in streams and coastal ocean waters.

Community Engagement in a Stream-network Assessment of Salmon Thermal-habitat in the Situk River Watershed of Yakutat, Alaska

The Situk River is among the most productive resource in Alaska, with nine native fish species and 10 times the density of juvenile coho salmon than any other Southeast Alaskan watershed. The associated fisheries in the Situk River and its adjoining estuary drive a $2 million economy for the community of Yakutat (population 600), with 89 percent of the households harvesting salmon for subsistence

Compilation of Historical Water Temperature Data for Large Rivers in Alaska using the Landsat Satellite Archive

Water temperature plays a large role in freshwater ecosystems in the Arctic and sub-Arctic. It affects the physical and biological features of rivers, like how the water interacts with the landscape and the life cycles of organisms that live in the river. For example, unseasonably warm water temperatures in Alaska’s large rivers in 2019 caused large numbers of salmon to die before they could reach

Enhancing Climate Adaptation for Native Communities in Western Alaska: Linking Pollinator Diversity and Abundance to Berry Production in a Rapidly Changing Environment

Berry-producing plants, a key resource in Alaska Native communities, provide primary subsistence and have been integral to maintaining cultural cohesion, sense of place, and physical ties to the surrounding landscape. Despite the importance of berry-producing plants, relatively little is known about their vulnerability to changes in climate and environmental conditions. The dynamics of insect popu

Evaluating How Snow Avalanches Impact Mountain Goat Populations in Southeast Alaska

Snow avalanches alter mountain environments and have both beneficial and harmful effects on wildlife. Avalanches can benefit wildlife by creating open areas for grazing but can also be deadly when animals are buried in avalanche debris. Avalanches pose high risks to mountain goats because they inhabit rugged and steep terrain, but the actual impacts of avalanches on mountain goats remain unknown.

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. 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 salm
