Photogrammetry to Monitor Walrus Body Condition and Calf Growth
Innovative drone technology provides critical insights into the body condition and health of Pacific walruses in a changing Arctic.
Assessing the Sustainability of Pacific Walrus Harvest
The Pacific walrus is a critical subsistence resource for many Alaska Native communities in western and northern Alaska but is subject to rapid habitat loss due to diminishing sea ice and an increasing anthropogenic footprint in the Arctic.
Sea Otter Diet Shifts in Glacier Bay During Population Expansion
A new study addresses changes in type and size of prey consumed by sea otters as they populated Glacier Bay, Alaska.
Increased Pathogen Exposure of Polar Bears in the Chukchi Sea
A new study examined changes in polar bear pathogen exposure across three decades. Prevalence of serum antibodies, indicative of exposure, increased between 1987-1994 and 2008-2017 for five pathogens.
Modeling, Mapping, and Measuring the Risk of Invasive Freshwater Species Across Alaska
A new report describes a collaborative effort to identify and prioritize aquatic invasive species known to be invasive in the contiguous U.S. and evaluate current and future habitat suitability for invasive species in Alaska.
