background: northern ontario, canada has a larger elder population, more resource-based employment, and limited access to physicians and specialists compared to southern ontario. given these important differences, it is possible that work disability rates will vary between the two ontario jurisdictions. objective: to determine the association between time lost due to workplace injuries and illn...

Freshwater ecosystems show more biodiversity loss than terrestrial or marine systems. We present a systematic conservation planning analysis in the Arctic Ocean drainage basin Ontario, Canada, to identify key watersheds for of 30 native freshwater fish, including four focal species: lake sturgeon, whitefish, brook trout, and walleye. created species distribution models fish accounted anthropoge...

The geology of the Calumet River region is briefly reviewed to provide a background fo r applied research in the area . The review relies heavily upon research conducted by scientists affiliated with the Indiana and Illinois Geological Surveys . At the end of the Late Wisconsinan glacial epoch , fluctuations in the Lake Michigan Lobe of the Laurentide Ice Sheet resulted in the formation of thre...

In an evaluation of diatoms as indicators of human disturbance in coastal ecosystems of the Laurentian Great Lakes, we characterized assemblage specificity to lake and habitat type to identify non-anthropogenic factors influencing indicator models. Surface sediment assemblages and environmental variables were collected along the U.S. coastline at 191 sample sites, which were classified by lake ...

Test borings in the western basin of Lake Erie have revealed an extensive sub-bottom deposit of sand in a triangular region bounded by Stony Point on the mainland shore of Michigan, Middle Sister Island in Ontario, and West Sister Island in Ohio. The 550 km deposit is overlain by up to 7 m of more recent lacustrine silts and clays. The sand beds have an average thickness of 2.3 m, yielding a to...

The First Nations communities of Grassy Narrows and Wabaseemong (Ontario, Canada) have been impacted by mercury pollution since the 1960s. This study was implemented with the objective of providing these communities with information on current mercury concentrations in their catch, in order to make appropriate fish consumption choices. A total of 851 fish samples, including Walleye, Northern Pi...

This study provides the first technique to investigate the turbulent fluxes over the Great Lakes from July 2001 to December 2014 using a combination of data from satellite remote sensing, reanalysis data sets, and direct measurements. Turbulent fluxes including latent heat flux (QE) and sensible heat flux (QH) were estimated using the bulk aerodynamic approach, then compared with the direct edd...

Food web structure is paramount in regulating a variety of ecologic patterns and processes, although food web studies are limited by poor empirical descriptions of inherently complex systems. In this study, stable isotope ratios (δ15N and δ13C) were used to quantify trophic relationships and food chain length (measured as a continuous variable) in 14 Ontario and Quebec lakes. All lakes containe...
