The role of microbiota-parasite interactions in the success of invasive freshwater fish

Project name in Czech
The role of microbiota-parasite interactions in the success of invasive freshwater fish
Annotation in Czech
Biological invasions pose a significant threat to freshwater biodiversity, with invasive alien species negatively impacting native biota, which in turn affects commercial fisheries. Symbiotic microorganisms play a significant role in the health performance of their hosts, act on their interactions with environment and evolutionary adaptation to changes. However, little is known about the role of microbiota in host invasion success in recipient ecosystems. Alien species may contribute to a loss of microbial diversity and/or shift the microbial composition in the native biota, potentially strengthening the negative impact of invasive species on native species. Moreover, native host microbiota may be modified by interactions with parasites co-introduced with their non-native hosts. This project focuses on two biological systems of invasive and naturalized/native freshwater fish species to investigate the role of microbiota in the success of invasive species and their indirect effects (parasite-mediated interactions, or competition for food and space) on microbiota of the native species.
