De nouvelles données et une nouvelle fiche info donnent un aperçu de la dispersion problématique de la moule quagga, une espèce envahissante, en Suisse. Les auteures et auteurs redoutent que la propagation agressive de cette espèce de moule affecte de manière importante les écosystèmes lacustres.
Dans le monde entier, les espèces envahissantes constituent l'une des principales raisons du recul de la biodiversité dans les écosystèmes. L'une de ces espèces envahissantes qui se propage actuellement dans les eaux suisses est la moule quagga (Dreissena bugensis). Originaire de la région de la mer Noire, elle est désormais répandue dans de grandes parties tm j'Bctyhq yd ms i'Hgofgbvo zl Vdaz.
