Species-level un-named taxa?

Titus Brown @titus.idyll.org · 8d

thanks! What is the right term when you are talking about multiple of them, tho? Current text: "many of the detected species are anonymous GTDB species that contain only MAGs and have no cultivated members."

Still reeling from the Stanford report on Brexit. Reduced GDP by up to 8% and investment by as much as 18%. The UK Treasury would have £40 billion more each year if Britain had remained in the EU. Devastating self-immolation.

Our latest paper is out with @adiop.bsky.social and @gmdouglas.bsky.social. We analyzed the extent of homologous recombination between bacterial species (introgression) and how it affects species borders (it can vary a lot depending on the approach used to classify species!). rdcu.be/eQAMf

Introgression impacts the evolution of bacteria, but species borders are rarely fuzzy

Nature Communications - It is commonly thought that bacterial species borders tend to be fuzzy, due to frequent exchange of DNA. Here, Diop et al. quantify the patterns of gene flow between core...

Don’t think much of the standard of English at that school if they say “heart-wrenching”. It’s “heart-rending” or “gut-wrenching”!

📣 We are proud of the publication of the second paper of @bbaker24.bsky.social PhD thesis. In collaboration with friends in Halifax we have studied the difficult question of the phylogeny of the DPANN archaea, composed of several phyla of highly reduced, fast-evolving epiparasites 🧵

rdcu.be/erkkU

Phylogenomic analyses indicate the archaeal superphylum DPANN originated from free-living euryarchaeal-like ancestors

Nature Microbiology - Phylogenetic reconstructions with conserved protein markers from the 11 known DPANN phyla reveal their monophyletic placement within the Euryarchaeota.
