Summary Increasingly, river managers are turning from hard engineering solutions to ecologically based restoration activities in order improve degraded waterways. River projects aim maintain or increase ecosystem goods and services while protecting downstream coastal ecosystems. There is growing interest applying techniques solve environmental problems, yet little agreement exists on what constitutes a successful effort. We propose five criteria for measuring success, with emphasis an...
Abstract Understanding the factors that affect water quality and ecological services provided by freshwater ecosystems is an urgent global environmental issue. Predicting how will respond to changes not only requires data, but also information about context of individual bodies across broad spatial extents. Because lake usually sampled in limited geographic regions, often for time periods, assessing controls compilation many data sets regions into integrated database. LAGOS-NE accomplishes...
As Ottawa River contamination is historical and resides in sediment, ecological risk trophic transfer depend on linkages between sediment biota. One of the ways which this linkage quantified through use biota accumulation factor (BSAF). In study, we present first field estimates BSAF for a number radionuclides. The strongest most consistent BSAFs were those 137 Cs deposit feeding taxa, suggesting that concentrations rather than dissolved drive uptake. For crayfish unionid bivalves do not...
The Ottawa River has received effluent from Chalk Laboratories (CRL) for more than 60 years. Some radionuclides and contaminants released in effluents are bound rapidly to particles deposited bottom sediments where they may be biologically available benthic invertebrates other aquatic biota. As part of a larger ecological assessment, we assess the potential impact contaminated vicinity CRL on local community structure. Using bivariate multivariate approaches, demonstrate that operations have...
Canadian Nuclear Laboratories’ Chalk River Laboratories (CRL) site is situated on the banks of Ottawa River, about 180 km northwest City Ottawa. Since 1947, has received effluent from CRL’s operations. this time, and in particular during operation national research experimental reactor (1947–1992), radionuclides (mainly 60 Co 137 Cs) mercury released effluents have accumulated deep-water sediments downstream CRL. In following, we present a holistic summary characterization historical...
