St. Helena Island supports nationally significant populations of northern fulmar (Fulmarus glacialis), Thayer’s gull (Larus thayeri) and High Arctic brant (Branta bernicla hrota), as well as locally important numbers of other species including common eiders (Somateria mollissima borealis) and...

Waterfowl and waterbird populations were monitored in wetlands and ponds along the highway corridors in the southern Yukon between 1991 – 2016. Approximately 200 wetlands were surveyed once a week for a period of 5 weeks beginning in early May (1991 – 2014); the survey period was reduced to 4...

This study aimed to evaluate the toxicity of naphthenic acid fraction components (NAFC) from fresh oil sands affected-water (OSPW) on the embryo-larval stage of the fathead minnow (Pimephales promelas) and the walleye (Sander vitreus). The assessed endpoints were hatch success, growth,...

This study aimed to determine whether the pharmaceutical metformin had toxicological effects on the fathead minnow (Pimphales promelas) in their various life stages—from eggs to adulthood. Endpoints included survival, growth, and reproductive development. Fathead minnows were exposed to metformin...

This study aimed to provide insights into how climate-driven diet shifts may impact contaminant exposures of Arctic species. We compared feeding ecology and contaminant concentrations in ringed seals (Pusa hispida) from two Canadian sub-Arctic (Nain and Arviat) and two Arctic sites (Sachs Harbour...

This dataset contains results from an eelgrass classification for Bouctouche Bay, New Brunswick. True colour aerial photography at 57 centimetre resolution was collected on September 2, 2009 by Nortek Resources of Thorburn, Nova Scotia (http://www.nortekresources.com/). Image classification was...

An eelgrass distribution map was classified from remotely sensed imagery in Richibucto Harbour, New Brunswick. Derived from a Quickbird satellite image collected on August 28th, 2007 at as close to low-tide as possible. Quickbird's ground resolution is 2.4 m. Classification was objected-oriented...
