Ecological Stressors

The ecological and economic costs of an invasive quagga or zebra mussel infestation in the Pacific Northwest of the U.S. would be significant. The development of invasive mussel monitoring programs in the Pacific Northwest provides a unique opportunity to evaluate a regional invasive species detection effort early in its development. Although efforts are underway to monitor for the presence of...

A study was conducted to identify habitat characteristics associated with age 0 White Sturgeon ( Acipenser transmontanus Richardson, 1863) recruitment in three reaches of the Columbia River Basin: Skamania reach (consistent recruitment), John Day reach (intermittent/inconsistent recruitment), and Kootenai reach (no recruitment).

Toxic chemical pollutants have been released into Puget Sound for decades by human activities. There’s a wide range of contaminants, from persistent compounds like polychlorinated biphenyls (PCBs) and flame retardants to contaminants of emerging concern. Aquatic species can be exposed to and accumulate contaminants, causing disease or disruption of biological processes like growth or reproduction...
