Greetings for the month of September: the Haervest-monath (Harvest Month). Today’s microbiome digest consists of a cool editorial article on hidden theatre of microbes. The digest also features two interesting reviews; first one detailing the role of skin microbiota in forensic sciences and the second one with focus on association of sponges and their microbiome.

Let’s celebrate the month of September with some fascinating microbiome studies.

There are flowers enough in the summertime,
More flowers than I can remember—
But none with the purple, gold, and red
That dye the flowers of September!

Greetings!

Today’s microbiome digest has something for everyone. We have several articles focused on the human microbiome, a few animal studies, and quite a few articles focused on environmental bacteria found in soil, water, and even a cave! I want to highlight one article focused on the impact of spatial proximity on territory among bacteria. Although the article specifically focuses on skin bacteria, it’s relevant to anyone studying microbial communities!

Enjoy!

Hello from the Sonoran Desert! In today’s digest, you’ll find quite a few exciting papers! For those interested in soil microbiology, you’ll find in today’s digest a very interesting piece on the the biodiversity and ecology of protists in the soils of the McMurdo Dry Valleys (Antarctica). This piece is particularly exciting given that the role and impact of protists in polar regions is largely unknown and understudied.

Curious readers should also take a look at the amazing study by Dunaj and collaborators focusing on spider’s associated microbiome. This piece examines the host-microbe co-evolution of different widow spider species showing a strong congruence of the microbiome beta-diversity and the host phylogeny.

Finally, in today’s non-microbiology pick, I recommend a preprint, that explored the relationship between the use of jargon and citations in cave research articles. Interestingly the authors suggest that the juse of jargon in title and abstract significantly reduces the number of citations a paper recieves!

Have a great Sunday!

Greetings!

Today’s digest is heavy on environmental microbiology with topics ranging from marine microplastics to carbon budgets to kitchen waste. I want to especially highlight a study that examines the phyllosphere of the mānuka. They found that the mānuka, or tea tree, has a stable core microbiome and variation in the non-core taxa is explained by biogeographical patterns.

Enjoy!

Good morning from Massachusetts! Dr. Elisabeth Bik will be giving a Zoom talk today on research misconduct in biomedical research. You can register at the link under events. Fittingly, today’s digest includes a preprint on the effects of retraction after misconduct on citations. Other highlights today include an entire theme issue on the microbiome and host evolution and a paper on phylogenomic analyses of archaea attempting to elucidate the DPANN lineage. In early life, the placental microbiome debate rages on with a paper demonstrating evidence for contamination rather than an actual placental microbiome. Finally, I have highlighted a paper studying whether soil archives can give us a glimpse into soil microbial communities of the past.

Have a great weekend!
