Ringed seals (Phoca hispida) have been used as bioindicator species of environmental contamination in Canada since the 1970s. In the present study, seals were harvested during subsistence hunts in four regions of the Canadian Arctic: Beaufort Sea, Arctic Archipelago, Hudson Bay, and coastal...

Freshwater mussels contribute important ecological functions to aquatic systems. The water filtered by mussel assemblages can improve water quality, and the mixing of sediments by burrowing mussels can improve oxygen content and release nutrients. However, nearly 70 percent of North American...

The study examines the parasite communities in Athabasca River Trout-perch (Percopsis omiscomaycus) at five sites along the main stem of the Athabasca River to explore whether any observed changes in parasite abundance or community structure might correlate with small-scale variations in water...

This collection houses PDFs of active BBS route maps, which are grouped by province or territory. These maps allow BBS volunteers in Canada to easily locate the start of their route, and to navigate the official route. The BBS is jointly coordinated by Environment Canada's Canadian Wildlife...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 3 site locations (Frenchman's Bay, Tommy Thompson, and Toronto Island) within the Toronto and Region Area of Concern. Halogenated Phenolic Compounds...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 2 site locations (Wheatley Harbour, and Hillman Marsh) within the Wheatley Harbour Area of Concern. Halogenated Phenolic Compounds have emerged as an...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for Brown bullhead (Ameiurus nebulosus) collected from three site locations (Frenchman's Bay, Toronto Island and Tommy Thompson) within the Toronto and Region Area of Concern for 2003 and 2006. Supplemental...

The Richelieu River, Quebec, is a highly-regulated waterway subject to numerous anthropogenic influences from municipal effluents and agricultural activities. Parasite communities in 234 spottail shiners (Notropis hudsonius) were examined from 4 localities in late spring 2003 and 2004. Parasite...

Neonicotinoids are the most widely used insecticides in the world and selective toxicity has resulted in the rapid and ubiquitous use of these compounds. Neonicotinoids are a class of neuro-active insecticides chemically similar to nicotine and are widely used in agriculture to protect crops from...

This dataset contains the fish health metrics (length, weight, gonad size, etc.) for White Sucker (Catostomus commersonii) collected from three site locations (Kaministiquia river, Kaministiquia river downstream and Little Gravel river used as a reference site) within the Thunder Bay Area of...
