Biologists clip the tip of one of the ventral fins of a sheefish that is in a cradle in the Selawik River, Alaska. This study was collecting genetic samples to help find impacts of fine sediment on sheefish. The results were no impacts due to low amounts of sediments present.

Bar-tailed Godwits - photo taken on mudflats near Cape Avinof, Alaska. USGS and USFWS recently found that almost the entire population of Alaska-breeding bar-tailed godwits feed along sand bars near the mouth of the Kuskokwim River in autumn. These godwits spend the nonbreeding season primarily in eastern Australia an
