!!!! PhD position!!!!
#SUMO modification in plant DNA damage repair. Join our team @pecinka-grp.bsky.social and work on this cool & still understudied topic. More info ⬇️⬇️⬇️
It lives deep in soil and diverged in the TRIASSIC (~200-250 mya). This lineage survived extinctions and ice ages, yet today only 1 species is known to science.
Where exactly it fits within Elateroidea remains uncertain. Deep-soil habitats clearly hold many more secrets.
We describe Badmaateridae, a new beetle FAMILY from Chile!
Badmaater chilensis is blind, wingless, and extremely small (~1mm).

Awesome to see the first chapter of my PhD out in MBE!
We used a suite of methods to describe the venom system of the green lacewing. Take a look if you're interested in everything from venom system morphology to the molecular evolution of novel traits

PhD position available in evolutionary genomics/bioinformatics (hoehnalab.github.io/job_adverts/...). Topic: analyzing gene expression evolution across several firefly species and linking expression changes to genomic architecture. The position is jointly supervised with @anaevolcatalan.bsky.social
"...researchers who invest time in their students tend to lead more-productive, more-collaborative groups and attract stronger future students than those who do not." "Time spent with the next generation of scientists is an investment."

One month later first instar larvae are hatching. 🤩
This work shows the first overview on the population genetics and demographic history of the big European firefly, **Lampyris noctiluca**. Feeling very happy this work is out :) academic.oup.com/mbe/article/...
Phosphaenus hemipterus - one of only 3 firefly species in Czech Republic with both sexes flightless! Was lucky enough to find pupae a while back and now they're already mating in my setup. Fingers crossed for eggs!
Urgent need for improving the statistical properties of summary methods and the computational efficiency of likelihood methods for inferring #gene flow using #genomic sequence data academic.oup.com/sysbio/advan...
Friends from department of Entomology at National museum in Prague are again organising "Immature Beetles Meeting". I highly recomend this meeting to all the researchers and lovers of Coleoptera larvae. #Coleoptera docs.google.com/forms/d/e/1F...
Possible game-changer.
Our review on caddisfly silk genetics is out in @cp-trendsgenetics.bsky.social. We’re excited about new developments in the field and we were stoked to have the chance to cover them in a review. We hope it is useful resource for people interested! www.cell.com/trends/genet...
New paper out 📝✨
"k-mer approaches for biodiversity genomics"
We discuss k-mer spectra, sex determination, allopolyploid subgenome separation, among other topics - and offer a large tutorial list

WASTER’s ability to accurately estimate trees from low-coverage sequencing data without relying on assembly and alignment will lead to substantially reduced sequencing and computational costs in phylogenomic projects. www.biorxiv.org/content/10.1... #genomics #evolution #phylogeny

Many academics point to bioRxiv as “the one thing improving science publishing”.
If so, the one thing you all can do is persuade colleagues to submit and make this a norm. 1/2

We mapped optix (again?!) as the switch gene of a natural polymorphism, this time controlling silver patches of a mountain butterfly. Gorgeous RNAi validation, evidence of selective sweeps, introgression
New paper with @snaildit.bsky.social❗
You can use paralogs to reduce long-branch attraction!
This will be especially helpful when there are no extant taxa that can be sampled to break up these branches.

Our Lampyris sardiniae colony celebrates 20 years in 2024, and slowly approaching generation 27! 🎄 Best early Christmas gift ever - just received the original founder pair and F1 generation specimens preserved in alcohol from 20 years ago! 🧬✨
An image showing a range of fossil scorpions, arranged by age. These are lovely fossils, ranging from scorpions in rocks, through ones dissolved out of rocks or resolved using CT scans, to photos of more recent scorpions in Amber. If you want the full details: (A) Palaeophonus caledonicus Hunter, 1886 (Dick Institute, Kilmarnock, UK) from the mid-Silurian (Llandovery to Wenlock) of Lesmahagow, Scotland, UK, image courtesy of Lyndsay C. Jess, and by permission of East Ayrshire Council/East Ayrshire Leisure Trust, and a reconstruction from Pocock (1901). (B) mid-Silurian Eramoscorpius brucensis Waddington, Rudkin & Dunlop, 2015 from Canada. (C) Proscorpius osborni Whitfield (1885b), Yale Peabody Museum (YPM IP 545850); photo by Jessica Utrup 2019. (D) Lower Devonian Waeringoscorpio hefteri Størmer (1970, image source Poschmann et al., 2008). (E) Pulmonoscorpius kirktonensis from the Lower Carboniferous of the UK (courtesy of Andrew Jeram). (F) Compsoscorpius buthiformis from the Upper Carboniferous of the UK (left: courtesy of Lorenzo Prendini, AMNH; right: Legg et al., 2012).

For #FossilFriday have you ever considered the scorpion fossil record? This is surprisingly rich, but how we categorize these animals transcends being a hot mess. It's a spicy disaster. My colleague Jason and I wrote a paper on it which came out today:
