Higher organisms are not only part of ecosystems - they also represent an ecosystem for a diverse assemblage of microbes. These microbiota are important for many physiological processes of the host (e.g. development, digestion, but also defense against parasites and disease). With the help of moder sequecning technology we investigate the role of mircrobiota in various organs of oysters, mussels and fish under changing envrionmental conditions and infection by parasites. We could show that a stable, diverse microbial community in the hemolypmh can protect marine bivalves from infections, but that these communities are also vulnerable to environmental pertubations and climate change linking the envrionment to host fitness via its microbiota.
