| Abstract |
Intensive malacological surveys coupled with environmental DNA analyses in France has led to the discovery of new populations of the quagga mussel Dreissena rostriformis bugensis (Andrusov, 1897), an introduced and invasive freshwater bivalve species. Molecular analyses confirmed the identification of the species based on a barcoding approach using both CO1 and 16S genes fragments. Discovered in 2011 in the rivers of north-east France, the quagga Mussel has now colonized the Rhône drainage. This advance represents not only the colonization of a new coastal drainage (the Rhône Rivers flows to the Mediterranean side of France), but also a spectacular 400-km leap south of its previously known range. Further expansion routes provided by canals between main coastal drainages are discussed. For the first time, we propose to use environmental DNA to assess absence, thus paving the way for future freshwater invasive species monitoring methods. |
