Invasive dreissenid mussels (Dreissena polymorpha and Dreissena bugensis) have a profound effect on the total phosphorus (TP) budget in Lake Ontario, which turn influences ecological processes such as resurgence of benthic alga Cladophora. A validated three-dimensional integrated hydrodynamic modeling framework is applied to quantify impact that dreissenids spatial species distribution TP lake....

We describe, explain, and “predict” dispersal and ecosystem impacts of six Ponto-Caspian endemic species that recently invaded the Great Lakes via ballast water. The zebra mussel, Dreissena polymorpha, and quagga mussel, Dreissena bugensis, continue to colonize hard and soft substrates of the Great Lakes and are changing ecosystem function through mechanisms of ecosystem engineering (increased ...

The influence of 3-methylcholanthrene to zebra mussel (Dreissena polymorpha) larvae was studied. The artificial spawning of zebra mussels was used for obtaining larvae. Two different concentrations of 3-methylcholanthrene were used. The chromosome analysis showed a significant increase in chromosome aberrations (CA) at the higher concentration of the compound. The resistance of zebra mussel lar...

The identification and risk assessment of potential biological invaders would provide valuable criteria for the allocation of resources toward the detection and control of invasion threats. Yet, freshwater biologists have made few attempts at predicting potential invaders, apparently because such efforts are perceived to be costly and futile. We describe some simple, low-cost empirical approach...

In environmental quality bioassessment studies, analysis of host-parasite interactions may well be a valuable alternative to classical macroinvertebrate sampling approaches. Herein, we investigated whether zebra mussel (Dreissena polymorpha) parasites could be useful biomonitoring tools. Mussel populations were sampled twice at two sites in northeastern France representing different levels of c...
