- Reposted by Yann DussertHey @maureenbug.bsky.social or other nudibranchophiles - is this a nudi? (From near shore reef in Moorea)
- Had the opportunity to see more than a dozen pink pigeons (Nesoenas mayeri) in the National Park of Black River Gorges in Mauritius. Brought back from the brink of extinction, there are now 500-600 individuals of this endemic bird on the island.
- A few more common, non-endemic birds were also here: red-whiskered bulbuls and village weavers
- Apparently it's #Crustmas, so here's another hermit crab (Calcinus sp?) and his neighbour, and a crab crab (Grapsus tenuicrustatus?)
- And for some change of pace, an helmet urchin and a fish (unidentified) sunbathing on the rocks.
- Some hermit crabs found on the Mauritius coasts, might be Calcinus laevimanus (yes, I'm a bad photographer)
- After working for more than one year on the @atlasea.bsky.social project, I had to buy this one.
- Reposted by Yann DussertWe are thrilled to announce the first official release (v0.1.8) of #𝗯𝗲𝗱𝗱𝗲𝗿, the successor to one of our flagship tool, #𝗯𝗲𝗱𝘁𝗼𝗼𝗹𝘀! Based on ideas we conceived of long ago (!), this was achieved thanks to the dedication of Brent Pedersen. 1/n

- Reposted by Yann DussertClaire Merot opens the afternoon session at the #biodiversity25 with a presentation about the structural genetic diversity across the tree of life. Structural variants (SVs) are in order de magnitude higher than SNPs. TEs accounts for many SVs. SVs are different across different lineages.

- Reposted by Yann DussertVersion 5.1.1 of the PR2 database has been released. The major novelty is the inclusion of the recently published eKOI database (coi gene- doi.org/10.1093/data...) in the web interface. The 18S rRNA database is not changed so you can use 5.1.0 or 5.1.1 for metabarcode annotations

- Reposted by Yann DussertATLASea Mission – Day 6 In the dissection room, the final sampling steps are underway 🔬 Tissue fragments are collected, labeled, weighed, and logged into a data sheet for full traceability ❄️ Samples are flash-frozen in liquid nitrogen at -196°C to preserve DNA quality for sequencing at Genoscope
- Reposted by Yann Dussert𝑳𝒊𝒎𝒂𝒓𝒊𝒂 𝒕𝒖𝒃𝒆𝒓𝒄𝒖𝒍𝒂𝒕𝒂 bivalves live under rocks generally between 2 and 12 m deep. Individuals can propel themselves by clapping their valves to expel water & jump on the sea floor. Tentacles are sensory organs, and together with the foot, can be used to build nests in sand & gravel for reproduction.

Dragged sediments are sieved and size-fractioned - revealing hidden benthic diversity. Uncertain samples go into aquaria, then safely back to the sea if not selected. #MarineBiodiversity
- Reposted by Yann DussertATLASea has just launched a new sampling campaign in one of the most iconic sites of marine biodiversity.

- New preprint on sex determination in a terrestrial isopod, Armadillidium vulgare! We located the genome region harboring the M gene, a locus functionally analogous to an XY system. Part of the PhD work of Baptiste Lhéraud at EBI lab (@univpoitiers.bsky.social). doi.org/10.1101/2025...
- The M gene is one of several sex determinants (ZW system, f-element, Wolbachia) in A. vulgare. It is thought that the masculinizing M allele has been selected to re-establish balanced sex ratios in some pops in which the feminizing f-element, another sex determinant, is present.
- Highlights: • Around 2 Mb with no recombination with the M gene, and different from the ZW locus • The M gene region contains 34 genes, among them the one coding for the androgenic gland hormone, involved in male sexual differentiation • Likely recent emergence of the masculinizing M allele
- This work has been supervised by Jean Peccoud (EBI, @univpoitiers.bsky.social ) and Richard Cordaux (EGCE lab, @ideevl.bsky.social ). Baptiste Lhéraud is currently working in the Ecologie Microbienne lab in Lyon! doi.org/10.1101/2025...
