How specific are heritable symbioses? And what can we learn from swapping obligate symbionts across host species? We address this in our latest, led by @inespons.bsky.social & in our collaboration w/ @microbiome.bsky.social 🦠🪲 Out today in @natcomms.nature.com! 1/n www.nature.com/articles/s41...

Check out our latest pre-print of our favourite pets - the breviates. This work was led by Zhezhen Yi in collaboration with @andrewjroger.bsky.social and many others! By studying diverse breviates we were able to see how different metabolic pathways can evolved in response to low-oxygen.
