Tolerance to environmental stress - an important component of invasion success

The Chinese pond mussel Sinanodonta woodiana is an invasive bivalve species present in the flowing and standing waters of most of Europe. In a series of physiological and toxicological experiments, we examined if invasive mussel (S. woodiana) is more tolerant to environmental pressures, in comparison with indigenous mussel (Anodonta anatina). The activity of both electron transport system (ETS), and oxidative stress-related enzymes (catalase, glutathione reductase and cholinesterases), as well as the comparison of the activity of multixenobiotic resistance mechanisms (MXR) in gill tissue, were used to evaluate a physiological response on water temperature extremes, feeding and starving, and zinc contaminations. S. woodiana showed higher tolerance to metal contaminations as well as to increased water temperature which is an important physiological benefit for further invasion success, especially in the context of climate changes.
