Polybrominated diphenyl ethers (PBDEs) are abundant in aquatic environment. However, only few studies have investigated their impacts on freshwater invertebrates. This work aimed to study the effects of BDE-47 and BDE-99 congeners on the chitobiase and chitinolytic enzymes activities of the freshwater amphipod Gammarus pulex, according to gender, PBDE concentration and time of exposure. In addi...

The freshwater amphipod Diporeia is a dominant macroinvertebrate speciesin Lake Superior’s benthic community and an important prey item for many fish. Acapacity to predict growth and production rates of Diporeia using a bioenergeticsmodel requires information on physiological processes of the species. The objectiveof this study is to quantify oxygen consumption of Lake Superior ...

The main objective of this study was to assess how mangrove reforestation has influenced litter degradation and concomitant nutrient dynamics in previously deforested plantations. Dynamics of nutrients (carbon, nitrogen and C:N ratios) in decomposing leaves of conspecific species were investigated with litterbags in Sonneratia alba and Rhizophora mucronata reforested treatments using appropriat...
