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...

Citizen science collaboration with the U.S. Geological Survey in Alaska Citizen science collaboration with the U.S. Geological Survey in Alaska

Citizen science is science undertaken by the public, usually in collaboration with professional scientific institutions. It encourages citizens to tackle real-world scientific problems and augments traditional science by expanding the coverage of data collection and by reducing costs of fieldwork in remote locations. Information collected by volunteers enables us all to gain a deeper...
