Describing Critical Water Sources for Arctic River Ecosystems
Aufeis, also known as icings, forms when groundwater flows to surface during the winter and freezes and is a source of water in northern Alaska.
Geese Migrating over the northeast Pacific often Fly at the Height of Wind-turbine Blades
How do migrating geese select their flight altitudes over the open ocean and is this at the same height as wind-turbine rotor blades?
Determining the Importance of Post-den Emergence Behavior of Polar Bears
The number of days after emerging from a winter den can be critical for polar bear cub survival.
Environmental data can determine changes in a polar bear population when direct data collection is not feasible
This study and others provides a template for using environmental and ecological data that can improve polar bear population monitoring.
Environmental changes that fueled sea star declines along the Pacific coast
The USGS Alaska Science Center, NOAA, and colleagues examined the effects of the wasting epidemic on sea star populations across the eastern Pacific (from Alaska to Mexico) over the last decade.
eDNA Applications for Salmon Research and Monitoring
A new synthesis document summarizes the applications of environmental DNA for describing distribution, abundance, and health of Atlantic and Pacific salmon.
Rapid Population Decline in McKay’s Bunting
A new report describes a 38% decline in the McKay’s Bunting population between 2003 and 2018.
