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...

In this study, seven non‐specific biomarkers were compared in Spottail Shiners (Notropis hudsonius Clinton) from localities receiving urban and industrial effluents and relatively clean localities in the St Lawrence River, Canada. Pigmented macrophages are involved in a variety of functions...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 3 site locations (Peche Island, Grosse Ile, Turkey Creek) within the Detroit River Area of Concern. Halogenated Phenolic Compounds have emerged as...

Increased productivity from sewage effluents can enhance species richness locally. Results from a study of Spottail shiners (Notropis hudsonius) in 1999 showed that prevalence and the mean number of myxozoan parasite species per host were higher downstream of the wastewater outflow from the...

The Atlas of Pelagic Seabirds off the West Coast of Canada presents maps that display the distribution of 48 species of seabirds and two species pairs (i.e., Red-necked and Red Phalaropes, and Hawaiian and Galapagos Petrels). Seabird surveys were conducted aboard commercial and Canadian federal...

The Alberta foothills are a primary source of spring runoff into the prairie regions to the east. For this reason, precipitation accumulations in the foothills are vital to prairie water resources. The Foothills Orographic Precipitation Experiment (FOPEX) was initiated in 2002 to study the...

Attribute data table which contains survey effort values for each season, total bird density, species richness value, species at risk score, and grid cell importance score.

Venlafaxine is an antidepressant and anti-anxiety drug that has been detected in municipal wastewater at low concentrations. To assess the potential of this compound to affect the survival, development and reproductive capacity of fish, we exposed Fathead minnow (Pimephales promelas) over a full...

Venlafaxine is an antidepressant and anti-anxiety drug that has been detected in municipal wastewater at low micrograms per litre (ug/L) concentrations. In this study, the nest-defense behavior of adult male fathead minnows (Pimephales promelas) was observed in fish exposed for a full lifecycle...

This dataset contains the overall health and endocrine function of Brown bullhead (Ameriurus nebulosus) and Goldfish (Carassius auratus) from the Wheatley Harbour Area of Concern using a suite of physiological and biochemical endpoints. Supplemental Information Funding for this study was provided...

This dataset contains the growth and survival data for Fathead minnow (Pimephales promelas) exposed to sediment from twelve sites within the Hamilton Harbour Area of Concern, as well as reference sediment (a mixture of sediment from two reference sites within Lake Erie, Long Point Marsh and Long...

Categorization was required by the Canadian Environmental Protection Act, 1999 (CEPA 1999) and is a first step to finding out which of these chemical substances require further attention in the form of assessment, research and/or measures to control their use or release. This task was completed...

This dataset contains the concentrations of halogenated phenolic compounds in plasma for the fish species Brown bullhead (Ameiurus nebulosus), from 4 site locations (Trenton, Deseronto, Belleville, Prince Edward Bay) within the Bay of Quinte Area of Concern. Halogenated Phenolic Compounds have...

Substituted diphenylamine antioxidants (SDPAs) and benzotriazole UV stabilizers (BZT-UVs) are additives used in industrial and consumer products to prevent degradation or colour change of materials, but their environmental fate and disposition are not well characterized. In this study, SDPAs and...

As part of a three year study funded by Environment and Climate Change Canada and Natural Resources Canada (ecoENERGY Innovation Initiative, project UOSGQ963; http://www.nrcan.gc.ca/energy/funding/current-fundingprograms/eii/4985) data were gathered to assess and monitor water quality conditions...

The Canadian Breeding Bird Census (BBC) Database contains data for 928 breeding bird plot censuses representing all known censuses of breeding birds carried out in Canada during the period 1929–1993. The 928 records in the database represent 640 unique census plots located in all provinces and...

Canadian Wetlands Inventory (CWI) data for the Appalache region. Created according to the method developed by the Canadian Wildlife Service, Quebec Region. Between 2003 and 2007, the Canadian Wildlife Service, Quebec Region (CWS-QC) produced wetland maps for several sites in Quebec. This mapping...

The Canadian Environmental Sustainability Indicators (CESI) program provides data and information to track Canada's performance on key environmental sustainability issues. The Population status of Canada's migratory birds indicator reports the proportion of bird species listed in the Migratory...
