Come join us to learn how to contribute to, and use, metAaRCive, a community-curated database of published ancient animal genomes! We'll also cover best-practises for metadata reporting in #aDNA studies and how to archive sequence data on the ENA! Sign up here: docs.google.com/forms/d/1E4k...

AaRC@aarc-community.bsky.social · 4d ago

@anders-bergstrom.bsky.social and @ddj-sa.bsky.social are hosting a workshop on September 17th to walk you through metAaRCive—from what it is to how to contribute. Open for sign-ups: docs.google.com/forms/d/1E4k...

Super cool resource! Something I wish existed a couple of years ago, so thanks for making it happen @anders-bergstrom.bsky.social & members of @aarc-community.bsky.social! There are still many more ancient animal genomes to add & we need more hands! If you're keen to help us out, see below 😊✌️

Need metadata for published ancient animal genomes? The metAaRCive project has recently made its first public release, containing metadata for 1518 published genomes across a range of species, curated by members of @aarc-community.bsky.social Find the release here: github.com/AaRC-Animal-...

I had an idea—just a hunch, really— on how to link #Popgen and #eDNA. I was lucky to be in a lab that embraced curiosity, open discussion, and let me run with it. One year, many equations, and a few too many simulations later, here’s the result: 🧬 Preprint now live: doi.org/10.1101/2025...

Estimating Organism Abundance Using Within-Sample Haplotype Frequencies of eDNA Metabarcoding Data

Environmental DNA (eDNA) metabarcoding provides powerful insights into species presence and community composition, but remains limited in its ability to quantify species abundance or structure. Here, ...

I use BHL every single day in my research and teaching. I could not write my books or articles without it, I don't know what my students would do without it, and I would have to radically rethink my career without it. This is more critical with funding cuts. Please, please someone support BHL.

Foundations: please step up and take over the Biodiversity Heritage Library (BHL). This is an absolutely essential scanned archive of all of the old journals and books from the 1500s to about 1920. Has been indispensable for my research. about.biodiversitylibrary.org/call-for-sup...

In an unconscionable decision, the Smithsonian Institute has decided to no longer support the Biodiversity Heritage Library from 1 Jan 2026. Please someone step up and take it over.

Today was truly inspiring. Something happened that we’ve never seen before, you made noise in places that rarely see protests like this. Communities across traditionally conservative areas hosted historic turnouts.

If you have a public platform & spent years calming everyone down, telling us Trump was not a danger,was not racist, & arguing that the best way to deal w/Trump was to laugh at him, berated ppl who used the word fascist, insisted that the two parties are the same, admit YOU WERE WRONG.

Many, if not most, of us depend on open, accessible research infrastructure to do our work and improve the world around us. But political support for such systems is not always there, or can change rapidly - consider signing below mitigate some that risk. investinopen.org/blog/stateme...

Check out our new method for summarising BEAST trees. The CCD0-MAP tree gives much more accurate results than MCC tree. It returns the tree that maximises the product of sampled clade probabilities regardless of whether that tree was sampled. Highly recommend :) journals.plos.org/ploscompbiol...

Not true. I'll give you some examples of when styles crossed over from womenswear to menswear, and how men have worn straight-up womenswear or just feminine styles in cool ways. 🧵

A screenshot from Twitter. The original tweet reads: "Rapper Kenderick Lamar wore size 29 women's jeans to Super Bowl LIX." The tweet garnered over a thousand replies, most negative. I (Derek Guy) screenshotted that tweet and wrote: "so funny to see history repeat itself. men who wear slim fit and stretch denim—both of which were once considered strictly for women—criticizing kendrick for wearing flares bc they were on the women's aisle. in ten years, you'll be in flares clutching pearls about something else" Then another user replied to my tweet, saying: "Wearing women’s clothes has never been in style, homo."
