I am so proud & happy to see our Potamo genome assembly finally out there in the world! The process ended up being way more challenging than expected, but for some really cool reasons. ❤️🐌🧬
TLDR: Surprise! A VERY recent WGD.

Independently evolved supergenes control colony social organization and queen reproductive strategies in several ant lineages. Sigeman et al. uncover a novel 9 Mb supergene controlling queen size and social organization in Myrmica ruginodis.

#Haplodiploid inheritance is found in all species of #Hymenoptera. @mwbstr.bsky.social &co map the #sex determining #gene of the red mason #bee to the ANTSR gene region, suggesting a shared, ancient origin of #SexDetermination in bees & ants >150 Mya ago @plosbiology.org 🧪 plos.io/47COEtH
Complementary sex determination (CSD) in bees and ants. Top left: Single-locus CSD is likely to be the predominant mode of sex determination in Hymenoptera. CSD loci have been identified in two species: the honeybee Apis mellifera and the invasive ant Linepithema humile. The tree shows evolutionary relationships between these species and Osmia bicornis, the main subject of this study. The origin of Hymenoptera is estimated as 386 million years ago and the common ancestor of Apoidea and Formicoidea is estimated as 153 million years ago. Top right: Under single-locus CSD, females are heterozygous at the CSD locus, whereas males are haploid and therefore hemizygous. A large number of CSD alleles are expected to segregate in outbred populations. A small proportion of homozygotes at the CSD locus are produced by chance, when parents share an allele, which results in the production of sterile diploid males. Middle: An O. bicornis nest consists of a row of cocoons in a tube. The mother lays fertilized diploid eggs deepest in the nest and unfertilized haploid eggs closer to the entrance. Eggs develop into adults inside cocoons. Diploid eggs typically develop into females whereas haploid eggs become male. A small proportion of diploids that are homozygous at the CSD locus develop into diploid males, which occur amongst females and are larger than haploid males.

Particularly happy to see #bivalves! My PhD was almost entirely on bivalve #genomics, so Ive been drawing them for papers (self-promotion below) #MarineLife🖥️🧬

Tho this the first w/ soft parts too, instead of only the shell!

Day 12 of #invertober2025 is the Pacific razor clam
A vectorial digital drawing of a Siliqua patula, or Pacific Razor Clam, set against a pale blue background. The clam is shown extending its large, fleshy pale cream-colored siphon from one end of its shell. The shell itself is long, narrow, and slightly curved, with a glossy appearance. It is colored in shades of golden-brown and tan, featuring distinct concentric growth rings that run perpendicular to its length. The text "invertobter2025 - Day 12" is in the bottom right corner.

2/2🧵But lets showcase an outstanding project about #ant #genomics: @woodwideants.bsky.social #bugsky🖥️🧬

Have a look at our social profiles and website: loads of science, #SciComm & teaching!

And for the #invertober community, a little EXTRA for Day13: Formica paralugubris, or the red wood ant!
A vectorial digital drawing of a Formica paralugubris ant (a species of Wood Ant), viewed from above and set against a pale blue background. The ant has a distinct color pattern: the head is predominantly dark brown/black with some reddish-brown markings. The thorax and petiole are a bright orange-red/dark rust color, and the large abdomen is a solid dark brown/black. The legs are also dark brown/black. The text "invertobter2025 - Day 13 EXTRA" is in the bottom right corner.

1/2🧵Had a little PTSD for this pal👀
Lately Ive been working on #ant #genomics, and made some plates of ant morphology for #SciComm and teaching (EXTRA contents below).

Now for Day13 of #invertober2025 —the banded sugar ant— I... *exaptated* those drawings.

Perdóname madre por mi mirmecología loca🐜
​A vectorial digital drawing of a Camponotus consobrinus ant, or Banded Sugar Ant, viewed from above and set against a pale blue background. The ant has a two-tone coloration: the head is black, the entire thorax and petiole are a bright yellow-orange/amber, and the large abdomen is primarily black with a clear, prominent yellow-orange band across the top of the gaster. The legs are dark. The text "invertobter2025 - Day 13" is in the bottom right corner.
