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.

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.  Photo by M.

A spring fed stream in the Two-Medicine drainage of Glacier National Park is one of 2 new locations for the western glacier stonefly (Zapada glacier).

Early, in the spring it is easy to see some furry insects flying and hovering just above ground.

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.

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.

A stand of field sow thistle (yellow flowers; Sonchus arvensis), Canada thistle (purple flowers; Cirsium arvense), and Kentucky bluegrass (grass; Poa pratensis), all of which are non-native and growing near an oil well pad in Mountrail County, ND.
