Anthropogenic noise is now a prominent pollutant increasing in both terrestrial and marine environments. In the ocean, proliferating offshore windfarms, a key renewable energy source, are a prominent noise concern, as their pile driving construction is among the most intense anthropogenic sound sources. Yet, across taxa, there is little information...

The deep sea (>200 m) is vast, covering 92.6% of the seafloor and largely unexplored. Imaging and sensor platforms capable of surviving the immense pressures at these depths are expensive and often engineered by individuals and institutions in affluent countries as unique, monolithic vehicles that require significant expertise and investment to bui...

The North American Walleye sport fishery is a billion dollar industry. Bad and careless scholarship on the part of the ASIH and AFS Names Committee has led to “Sander,” the Latvian common name for Stizostedion lucioperca, being used as a generic name for Walleye, Sauger, and European Pikeperch. Generic names are supposed to be formed from Latin nou...

Wild Atlantic salmon populations in North America, essentially Canada, have faced a continuous declining process over the last 35 years. Current government programs to restore salmon stocks in rivers have not achieved the expected results, in terms of survival rates and fitness, of reintroduced individuals with respect to the wild born relatives. I...

A common goal of wetland restorations is to increase nutrient retention by reestablishing wetland vegetation and former hydrologic regimes. We tested the effects of two types of wetland vegetation and a control (river birch-bald cypress (RB-BC), rice cutgrass (RC), and bare soil (BS)) and two inundation regimes (three days and three weeks of inunda...

jats:p>Fish, whales, and seabirds along the productive west coast of Vancouver Island (WCVI), NE Pacific, rely on copepod prey that are assumed to be rich in lipid. However, the total lipid (TL) and fatty acid content of most copepod species and other mesozooplankton in this region have not been measured. To assess the diets and quality of zooplank...
