26 hours into the #BM100 4 runners are on loop 3, 3 runners are on loop 2, and 5 runners are in loop 1. Runners currently on loop 2 must begin loop 3 by 26:40 in order to continue. #BM100

Happy to have an article where one of the co-authors is my mum :):):):)

Finally! Influence of polimorphic inversions on demographic inference and the spruce bark beetle demographic history!

Demographic History Inferred From an Inversion-Rich Spruce Bark Beetle Genome

For a while (many years!) back, @eseb.bsky.social gave us €€€ to form a Special Topic Network. Formally, the network no longer exists, but informally for sure AND we can now pick the fruits of our labours! Here is one and the next post shows another... Thank you ESEB! 🙏

Reference genome choice compromises population genetic analyses Using a species-specific reference genome significantly improves the accuracy of population genetic analyses, as exemplified by mapping gray fox sequence data to genomes of several canid species. Mapp...

Super proud PI moment at #ESEB2025. Julia just presented her PhD project on selection inference in inversion rich genome of spruce bark beetle. Also at www.biorxiv.org/content/10.1...

Proud supervisor moment! Congratulations Julia!
Take and read how inversions influence selection inference.

A century of theories of balancing selection Traits that affect organismal fitness are often very genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature (...

Finally ready to see the world! Theories of balancing selection - past, present and future: www.biorxiv.org/content/10.1... A true collaborative effort that brought together theoreticians and empiricists, models, data, and fresh perspectives on how balancing selection can shape genetic variation.

Join us! @krynadachowska.bsky.social from our institute is giving a planary talk.

Apply now! Wieslaw is the best supervisor and the project is great! If you want to be supervised by a person from whom you can learn a lot, who cares about your scientific development and you want to work in our fantastic team - do not hesitate any longer! Please share!

Paper alert!
@JesperBoman et al bring empirical evidence for the idea that #chromosome number differences between taxa can contribute to #speciation!

Twenty years of microplastic pollution research—what have we learned? Twenty years after the first publication that used the term microplastic, we review current understanding, refine definitions, and consider future prospects. Microplastics arise from multiple sources,...

Disturbing review paper; our environment and body tissues are now thoroughly impregnated with micro-plastic particles. Doesn't seem ideal. www.science.org/doi/10.1126/...

Genealogical asymmetry under the isolation with migration model and a two-taxon test for gene flow Abstract. Methods for detecting gene flow between populations often rely on asymmetry in the average length of particular genealogical branches, with the A

My and Derek Setter's work on gene flow is now published in the latest issue of Genetics. We show that it is possible to detect past gene flow between two populations by summarising the asymmetry in pop-specific external branch lengths. 1/2

Highly recommended! great research and PI :)

Folks, please weigh in. If you've read/used my book - what's missing? What's out of date? What would make it more useful for you, or for your students?

A time-calibrated salamander phylogeny including 765 species and 503 genes Recent time-calibrated amphibian phylogenies agree on the family-level relationships among extant salamanders but had disparate sampling regimes and i…

Do you need a salamander phylogeny? You're in luck! We put together the largest salamander phylogeny to date based on molecular markers and used more fossil calibrations than any other currently available trees. 765 salamander species! Check it out!

I will be looking for a postdoc (in a year or so) :) If you are interested in temporal sampling, rapid adaptation in the context of inversion-rich genomes, get in touch!

Hi #Popgen #evolution #ecology people: I'm always looking for more Ne/Nc data to verify, scrutinize and add to a database, linking life history traits to Ne/Nc. If you see a paper with Ne and Nc data, pm it to me! thanks.
