Orange streams are increasingly common in the Brooks Range of northern Alaska. The orange stream color reflects oxidized iron, but also often indicates elevated heavy metal concentrations. Our ongoing study aims to document these occurrences and the timing of their onset.

This house wren was banded during the fall migration banding activities at EESC's Bird Banding Laboratory in Laurel, MD. 

Photographs from a mountainous star coral (Montastraea cavernosa) losing tissue to disease in Florida, USA.  (A) Colony in situ showing bare white, recently denuded skeleton with no turf algae growth (arrowheads) with dark discoloration along the active tissue loss margins (arrows).

Photomicrographs from a mountainous star coral (Montastraea cavernosa) in Florida, USA. (A) A large cluster of filamentous bacteria are within the gastrovascular space and gastrodermis (asterisk) and extending through mesoglea (arrow) with necrosis and loss of the surface gastrodermis (arrowheads). H&E stain.  Scale bar 200 μm.

Density plots showing higher probability of host occupancy, on average, under proactive disease management (b, right) versus reactive disease management (a, left) for chytrid fungus, Batrachochytrium salamandrivorans (Bsal). Adapted from 

Profile view of a Bell Jet Helicopter with a thermal infrared and true-color sensor co-mounted to the underside of the nose. These sensors are used in airborne thermal infrared surveys for remotely sensing land/water surface temperature.

A ghost forest stands in Goose Creek State Park in North Carolina. This is an example of a freshwater forested wetland that is transitioning to open water.

Preacher, a Boykin spaniel, holds a harvest duck in his mouth. He belongs to longtime waterfowl hunter Tyler Coleman. The duck has bird bands on its legs. 

Mallard is a large dabbling duck, length 15-16 inches, with a wingspan up to 36 inches.
