The rapid loss of arctic sea ice is forcing a larger proportion of the Southern Beaufort Sea polar bear (Ursus maritimus) population to spend more time on land, increasing chances of negative interactions between people and bears. In the United States, the Marine Mammal Protection Act (MMPA) protects polar bears from incidental disturbance from human activities. For the remote and roadless areas of northern Alaska, USA, effective management of small aircraft activity is necessary to limit disturbance, but effects of overflights on polar bear behavior are largely unknown. During 2021 and 2022, we intentionally exposed polar bears (n = 115) to systematic aircraft activity (helicopter, fixed-wing) until we observed...

Water temperatures affect the distribution, growth potential, and productivity of stream fishes that are targeted in subsistence, sport, and commercial fisheries across Alaska, making stream and lake temperature data critical for managing freshwater resources. Evaluating the variation in temperatures across Alaska will improve understanding of impacts of both climate change and development on freshwater habitats. However, collection and dissemination of water temperature data is an ongoing challenge across Alaska. To address this challenge, the research team will increase cooperation and coordination among data collectors in Interior Alaska by conducting an in-person stream temperature trainingand adapting the...
