| biotransformation and antioxidant enzymes of dreissena polymorpha for detection of site impact in watercourses of berlin. | this study investigated whether biotransformation and antioxidant enzymes of an organism tolerant to pollution such as the zebra mussel dreissena polymorpha can be employed to evaluate the extent of urban water pollution. activity changes of soluble and membrane bound glutathione s-transferase (s- and mgst), superoxide dismutase (sod), catalase (cat) and glutathione peroxidase (gpx) to environmental stress were explored in precultured mussels exposed for one day to one week at selected sites wit ... | 2009 | 19513445 |
| long-term response of dreissena polymorpha larvae to physical and biological forcing in a shallow lake. | müggelsee, a shallow eutrophic lake (berlin, germany), has been subject to global warming and concurrent reductions of anthropogenic nutrient loading during the past decades. here, we focus on the recent increase in abundance of dreissena polymorpha larvae. we aimed at ascertaining whether the change in abundance of larvae was driven by changes in climate, especially by climate warming, and/or by the concurrent changes in trophic state of the lake. both the numbers of small, newly developed larv ... | 2007 | 16964499 |
