Satellite image of resuspended volcanic ash cloud over Kodiak Island, Alaska
MODIS Aqua 1 km true color satellite image showing resuspended volcanic ash cloud (arrow) generated from high winds scouring exposed ash on the Pacific side of the Katmai volcanic range. The cloud stretches across the Shelikof Straight and western Kodiak Island. Image ID 2010333 taken November 29, 2010. Courtesy NASA.

Remnants of a spruce forest
Remnants of a spruce forest complex following a severe wildfire in the Yukon Flats National Wildlife Refuge, Alaska. Wildfires are the dominant landscape-scale disturbance operating at annual time scales in Alaska, and fires play a major role in the rate and extent of vegetation growth and productivity of a site.

The avian paramyxovirus is found across the planet, infect wild and domestic birds, and sometimes lead to disease outbreaks, but according to a new study led by the USGS, wild ducks and shorebirds do not appear to carry these viruses, which can lead to Newcastle disease that sickens or kills poultry.
