We have got a balanced mix for folks today of human, animal, plant, and free-living microbiome research. In particular I want to highlight the work of Inagaki et al., who tracked gut microbiome dynamics within Japanese termites (Reticulitermes speratus) during dispersal and colony formation. They observed a rapid increase then decrease of gut protozoa coinciding with larval hatching of a pioneering termite pair’s first brood; a pattern they call a ‘gut microbial pulse’ (what a wonderfully evocative term!). This is a neat example of how host-associated microbiomes might play a integral role in the ecology of free-living organisms.
