Hello, BlueSky! 🦋 Excited to reconnect, exchange ideas, and build a collaborative space driven by curiosity and innovation.

We’re launching the Dept. of Biodiversity Monitoring at SMNS!🚀 Using museum & monitoring collections, we study genomic diversity 🧬 and species persistence in a changing world.

Delighted that our paper about the distribution of genomic spans of clades/edges in genealogies (ARGs), and using this for detecting inversions and other SVs (and other phenomena that cause local disruption of recombination) is out in MBE academic.oup.com/mbe/article/... (1/n)
The Length of Haplotype Blocks and Signals of Structural Variation in Reconstructed Genealogies
Abstract. Recent breakthroughs have enabled the accurate inference of large-scale genealogies. Through modelling the impact of recombination on the correla

🔁Please share - we remind the SMBE community that the Call for Symposia for #SMBE2026 in Copenhagen is open.

We invite you to submit a symposium proposal to help shape the scientific content of our annual meeting.

🗓️Deadline: October 15th

alignments are mosaics of autocorrelated genealogies... nearby bases share ancestry until recombination alters the local tree. We derived the distributions of waiting distances for tree-change and topology-change events, extending prior single-population results to arbitrary species tree models.
figure illustrating the concept of an ARG, including recombination events that create no-change, vs. tree-change, vs. topology-change

♨️Live @ #BGEconnects in Brussels:

“Generation of high quality assemblies combined with #population studies should be of top priority for all economically important species to provide the tools for #sustainable exploitation”, says Leif Andersson from Uppsala University.

Hybridization and introgression are major evolutionary processes. Since the 1940s, the prevailing view has been that they shape plants far more than animals. In our new study (www.science.org/doi/10.1126/...
), we find the opposite: animals exchange genes more, and for longer, than plants

The first Aguillon Lab paper is officially out in early view at Evolution!! Led by postdoc @devonderaad.bsky.social, we’ve explored the hybrid zone between black-headed and rose-breasted grosbeaks in the Great Plains. #ornithology #hybridization #speciation #evolution doi.org/10.1093/evol...
Figure 1A from the paper shows the distribution of black-headed (western) and rose-breasted grosbeaks (eastern) throughout North America. Small illustrations of males of each species are shown. Black-headed has a rusty orange breast and black head, while rose-breasted has a small reddish bib with a bright white belly. There is an inset map of South Dakota showing the transect across the hybrid zone

Why do speciation rates vary across the tree of life?
Some of the best yet most underappreciated places for this investigation are natural hybrid zones.
This preprint takes you to the hybrid zones in the origin of species to find a clue. 👉 shorturl.at/N7FXE

It looks like the @eseb2025.bsky.social #museomics symposium was a great success. If you want to learn more about the analysis of genomics data derived from natural history collection, we only have 4 seats left for our course in Nov.

Our paper on the evolution of MUC19 in humans, Neanderthals, and Denisovans is finally out today in Science!

This has been a six-year effort by 13 authors to weave together 3 separate but related evolutionary stories around this one gene (more on thread 🧵).

The MUC19 gene: An evolutionary history of recurrent introgression and natural selection
We study the gene MUC19, for which some modern humans carry a Denisovan-like haplotype. MUC19 is a mucin, a glycoprotein that forms gels with various biological functions. We find diagnostic variants ...
