Biologist (Tyrone Donnelly) Conducting Field Work
Wildlife Biologist Tyrone Donnelly searches the shoreline from a skiff in Izembek Lagoon while conducting avian influenza surveillance. Pacific black brant, seen flocking in the background, stage within the refuge each fall to take advantage of the abundance of eel grass as forage.

Erosion along Alaska’s Arctic coastline near the village of Kaktovik
Neal Pastick – lead author of the study – investigating erosion along Alaska’s Arctic coastline near the village of Kaktovik. Permafrost-dominated coasts of Alaska have drastically changed as the result of coastal transgression and storm-surge flooding which can result in the loss of cultural sites and damage to infrastructure.

Bear scat.
When looking for a place to set up a capture location, biologists look for existing bear sign such as scratches on trees and bear scat. Sometimes traps are set in areas that have no obvious bear sign to determine if indeed bears are present.

Glacial fed alpine stream in Glacier National Park.
Scientists sample for alpine insects in streams like this near Blackfoot Glacier in Glacier National Park. Alpine streams environments in the northern Rocky Mountains are especially vulnerable to climate change due to rapid warming resulting in loss of glaciers and snowpack.

Western glacier stonefly on a snowy backdrop in Glacier National Park
A glacier stonefly (Zapada glacier) on a snowy backdrop in Glacier National Park. The species is threatened by climate warming induced glacier and snow loss and has been petitioned for protection under the U.S. Endangered Species Act due to climate-change-induced habitat loss.
