We’ve got a short digest for you all today. In particular, I’d recommend checking out Glowacki and Martens who’ve written a nice review of the polysaccharide utilization loci observed in bacterial members of the human microbiome (with a special emphasis on Bacteroides). Mhuireach, Wilson, and Johnson’s recent paper on the urban aerobiome is a nice contribution to growing recognition that we need to begin considering our environmental microbiome, not just those microbiota residing on or within us.

We have got a human gut microbiome heavy edition today, with two reviews of the early life microbiome and its affects on physiological development.

I also want to highlight the work of Chen et al. 2020, who nicely demonstrate that the zebra finch early-life microbiome converges upon the microbiome of the parent that reared them (rather than their genetic parent) in cross-fostering experiments. This is important as cross-fostering experiments have been a staple in studies of avian micro-evolution and eco-physiology in captive and free-living system. Therefore, variation in offspring phenotypes attributable to the ‘early life environment’, ‘nest effects’, or ‘foster parent effects’ might in some cases be partly proximately driven by microbiome variation. This is an important point of clarification since, as Chen et al. 2020 and other researchers have demonstrated, the microbiome can be vertically transmitted—unlike most early-life environment sources of phenotypic variation. Thanks for indulging me in my musings 😉

We’ve got a belated post for you today (sorry all!) with a good balance of recent research on plant, animal and free-living microbiomes. Rather than highlight specific pieces of literature, I would encourage any who are interested in the microbiome from an evolutionary perspective to check out the recording of the ERC funded IDEM group’s recent discussion of the Holobiont Concept, featuring some preeminent proponents and critics of this model.

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.

Hi folks! Another new volunteer poster here up from the ranks of the recently recruited. Today’s post is pre-print and plant/soil heavy. If up until now you’ve focused your reading on animal microbiomes, now’s a great time to check in on our photosynthesizing friends. Lots of great work today on the affect of management strategies on plant-associated and soil microbes. If the transition into the world of the leafy green is too jarring, perhaps try easing yourself in with Marchese et al.’s work on the mycobiome of sea cucumbers – a critter which is plant in common name only.
