Benthic Macroinvertebrate Recovery After Wastewater Treatment Plant Upgrades: Implications for Biomonitoring

River Research and Applications, EarlyView.
ABSTRACT During the past decade, major upgrades have been made to the Kitchener and Waterloo wastewater treatment plants (WWTPs) in the Grand River watershed in Ontario, Canada. As part of efforts to evaluate the effectiveness of these investments (>$450 M CDN), a benthic macroinvertebrate (BMI) monitoring program was initiated by sampling upstream and

Structure and functional genes associated with carbon, nitrogen, phosphorus, and sulfur cycling processes in periphyton: A comparison between natural and artificial rivers

River, EarlyView.
Network analysis of functional genes among prokaryotes, and eukaryotes in natural and artificial rivers. Abstract Periphyton in aquatic ecosystems plays vital roles in the elemental cycle process and is vulnerable to anthropogenic interference. However, few studies have explored the elemental cycles of carbon (C), nitrogen (N), phosphorus (P), and ...
