Alien Chinese pond mussels (Unionidae, Sinanodonta) in Russia: new records, the stages of the invasion, and its current status
摘要
Based on the available scientific literature and the results of our own research, with the involvement of information from social and mass media, we have summarized the data on new records, the state of populations, the origin, distribution, and the stages of the invasion of Chinese pond mussels (Sinanodonta spp.) in Russia. Most of the discovered populations apparently reproduce independently and are capable of existing without the arrival of newly introduced juveniles. More than half of the populations were found in water bodies with a natural thermal regime, and less than half were found near fish farms. This finding indicates a successful invasion of mussels into water bodies and watercourses of Russia, as well as their active distribution in zonal (non-heated) water bodies. An assessment of the possibility of expanding the Sinanodonta spp. invasion in Russia and its consequences is provided. Additionally, we assessed the possibility of using the variability of Chinese pond mussel shells to distinguish between species and populations in heated and unheated conditions, as well as the possibility of using the diversity of COI haplotypes to track the phylogeographic relationships and invasion routes.
