The Turkey Lakes Watershed (TLW) Study was initiated in 1980 by Environment Canada, Natural Resources Canada and Fisheries and Oceans Canada to evaluate anthropogenic perturbation of Canadian Shield ecosystems. Originally, the Study focused on the aquatic and terrestrial effects of acid rain, but now it includes research into the effects of other anthropogenic pollutants (e.g. toxic contaminants) and ecological perturbations (e.g. forest harvesting, climate change and fish habitat modification).

The data layer (.shp) presented is the result of an unsupervised classification method for classifying seafloor habitat on German Bank (off South West Nova Scotia, Canada). This method involves separating environmental variables derived from multibeam bathymetry (Slope, Curvature) and backscatter (principal components: Q1, Q2, and Q3) into spatial units (i.e. pixels) and classifying the acoustically separated units into 5 habitat classes (Reef, Glacial Till, Silt, Silt with Bedforms, and Sand with Bedforms) using in situ data (imagery). Benthoscape classes (synonymous to landscape classifications in terrestrial ecology) describe the geomorphology and biology of the seafloor and are derived from elements of the seafloor that were acoustically distinguishable.

Environmental quality data from water, fish and sediments in 20 lakes across Canada. Measurements include mercury, methylmercury, physical-chemical parameters such as pH and alkalinity, stable isotopes, fish biological data, nutrients, ions, and metals. The data collection includes sites with a period of record ranging from one year to eight years, starting in 2008. Fish analysed at each site include at least one top predator species and one prey species.

The data layer (.tif) presented are the results of using MaxEnt to produce a single species habitat map for Sea Scallop (Placopecten magellanicus) on German Bank (off South West Nova Scotia, Canada). Presence data derived from videos and still images were compared against environmental variables derived from multibeam bathymetry (Slope, Curvature, Aspect and Bathymetric Position Index (BPI)), and backscatter data (principal components: Q1, Q2, and Q3). Results represent a probability of habitat suitability for Sea Scallop on German Bank. Probability of suitability: The probability that a given habitat is suitable for a species based on presence data and underlying environmental variables (i.e.

These fish-eating colonial waterbirds breed and nest in colonies on islands in and around Fathom Five National Marine Park. Five species of colonial waterbird are monitored. These birds and their eggs are effective measures of environmental contamination and aquatic ecosystem health.

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 important class of environmental contaminants in aquatic vertebrates, wildlife, and humans. They represent 4 of the 7 classes of substances listed as chemicals of mutual concern in the Great Lakes. Supplemental Information

Funding for this study was provided in part by the Government of Canada’s Great Lakes Action Plan (GLAP) and in support toWheatley Harbour Area of Concern.

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 lifecycle in a flow-through system to nominal venlafaxine concentrations. During the 167–168 day exposure, no significant changes were observed in survival, or the weights and lengths of Fathead minnows. At maturity, there were no significant differences relative to controls in condition factor, liver-somatic index, or secondary sex characteristics in the venlafaxine exposed male or female fish.
