Description: Das Projekt "Exzellenzcluster 80 (EXC): Ozean der Zukunft" wird vom Umweltbundesamt gefördert und von Universität Salzburg, Fachbereich Organismische Biologie, Arbeitsgruppe Ökologie, Biodiversität & Evolution der Tiere durchgeführt. The establishment of an invader in its new environment depends among others upon non-trophic associations with other species ('symbiosis'). Invasive species may co-introduce their established symbionts, or species native to the habitat invaded by the neobiont may exploit the newly available host. While the ctenophore Mnemiopsis leidyi has been proposed a recent, potentially successful, invader to the North and Baltic Seas, essentially nothing is known about its symbionts and how they affect their host and its success in establishing in a new environment. As a start-up project for a study on host-symbiont co-evolution during invasion, the proposed project aims at identifying bacteria on the surface and inside the body of Mnemiopsis from the Baltic and the North Sea and comparing them with those found in the native range of Mnemiopsis. Based on a comparison with freeliving potential symbionts in the water body, we will shed light on host-symbiont specificity. On the long-run (follow-up project), this project aims at understanding how well Mnemiopsis integrates itself into (non-trophic) interactions with resident species, and how these interactions affect the ecology and evolution of this neobiont, and thus, its success in a newly invaded habitat.
