Rapid technological advances in microbial ecology are allowing us to challenge conventional assumptions regarding symbiotic microorganisms and their ecological and evolutionary relationships with the host. For example, in many cases, a one-to-one relationship between a host and a single symbiont has been assumed, but new evidence suggests that a suite of multiple species or strains of symbionts interact with the host in ways that cannot be understood under the simple one-to-one assumption. Similarly, symbiont research has tended to focus only on one or a few parts of the host body for the sake of simplicity and tractability, but new data suggest that host organs long assumed to be insignificant for symbiotic interactions often contain symbiotic populations that are important to the host, with dynamic exchanges of these microbes occurring across habitats. In this symposium, researchers working on flies, bees, beetles, butterflies, fishes, amphibians, and humans will present and discuss latest findings on these new questions on host-symbiont interactions toward a synthesis across a broad range of host taxa.
