Recent human gut research has revealed the fundamental importance of microorganisms to human health, with differences in gut microbiota linking strongly with diet, diseases, and overall performance. In comparison, far less is known about the relationships between gut microbiomes and host health in non-human vertebrates.
This project focuses on the structure of gut microbiomes associated with the largest group of vertebrates: marine fishes. In particular, this project will test whether range-shifting tropical fishes acquire new microbial taxa to assist in the digestion of food sources when they move into temperate waters. If confirmed, such acquisition would be a significant example of assisted evolution that may accelerate environmental adaptation in fish and the tropicalisation of temperate reefs.Â
