Estimated relationship between entrainment probability and proportion of river flow entering canals at Wapato Dam, Sunnyside Dam, and Prosser Dam on the Yakima River, Washington. The relationships are shown at the mean total river flow for (A) yearling Chinook Salmon, (B) juvenile steelhead, and (C) subyearling Chinook Salmon.

New World Screwworm is a fly (Cochliomyia hominivorax) that lays eggs in open wounds of warm-blooded animals. Once hatched, the larvae (maggots) consume the living tissues at the edge of the wound, leading to severe illness and death if left untreated.

Chris Pullano and Ryan Tomka load acoustic telemetry receives on to boat in lower Columbia River estuary. Field work was recently completed for the first year of a study to better understand how young salmon use restored habitats in the Lower Columbia River Estuary.

Chirs Pullano and Collin Smith unearth the buried cable tethering an acoustic receiver to shore in the lower Columbia River estuary.  Shifting sands frequently bury equipment making it difficult to retrieve. During the 2025 field season, researchers deployed acoustic telemetry equipment to track yearling Chinook salmon as they moved through both restored e

Ryan Tomka retrieves an acoustic telemetry receiver from the lower Columbia River estuary. During the 2025 field season, researchers deployed acoustic telemetry equipment to track yearling Chinook salmon as they moved through both restored estuarine wetlands and the main Columbia River channel.

Red spruce forests, once widespread across the central and southern Appalachians, now persist only in scattered fragments on mountaintops. 

Spruce Knob is the highest point in West Virginia, which offers incredible views of misty ridgelines and the unmistakable scent of spruce on cool mountain air.

This red spruce forest and understory vegetation are part of a larger patchwork of red spruce forest stands across the central and southern Appalachians, separated from each other by miles of hardwood such as maple, oak, and beech.

Gaudineer Knob in eastern West Virginia is home to one of the few remaining old-growth red spruce forests in the region, sitting as a unique reminder of what red spruce forests once looked like across the central and southern Appalachians.
