CINPOP

Comparison of invasive and native populations of Dreissena polymorpha : effects of environmental impact

2020 - 2021

The CINPOP project falls within the '12. Climate action, environment, resource efficiency and raw materials' of Horizon 2020. France and Ukraine share a common freshwater fauna, in particular bivalve molluscs. Among them, Dreissena polymorpha is successfully distributed in Europe (including France) and North America as an invasive species from the Ponto-Caspian region, including Ukraine. In addition, the zebra mussel appears to be a bioindicator species that has already been used to amplify chemical or biological contamination of watercourses. The rate of accumulation and the biological responses to such contamination have made these molluscs interesting bioindicators of environmental pressures. The transplantation technique, which is easy to implement, means that this species can be actively monitored. The aim of CINPOP is to study the immunoreactivity of native and invasive mussels in order to understand and predict the general regularities of their dependence on new environmental impacts, particularly rising temperatures.
