Congratulations Pedro, that task is definitely challenging and it's nice to see it having a real impact in the reproducibility of phylogenetic analysed at JVP.

Felicidades Pedro!

Congratulations, well deserved!

Does the expected behaviour happen when running the code directly on the R console or Rscript?

Include fossils in your phylogenies whenever possible!

tbea: tools for pre- and post-processing in Bayesian evolutionary analyses Abstract. Estimating phylogenies in which branch lengths are expressed in units of absolute time is crucial for testing hypotheses in evolutionary biology.

RRrrrr, a scientist's best friend. A new package "tbea" has made estimating phylogenies even easier than before, crucial for testing hypotheses in evolutionary biology! Combining fossil, genetic & geological data, this study looked at S American Cynodontidea as an example 👇

Benchmarking of software for Bayesian sampling of divergence times using genomes

We have a new Bayesian sampler of divergence times that is smoking fast! Benchmarking by the exceptional @lauramulvey.bsky.social

I'm happy to share our latest (and wrap-up) paper from the Genome of Melody project in this special collection on cultural evolution royalsocietypublishing.org/rstb/article...

Hello, I'm interested!

Thank you to @palaeopercs.bsky.social for inviting me, the talk is already available on YouTube: youtu.be/k-yWOsyF0Jw

Looking forward to giving this talk. See you all on Tuesday!

Congratulations Etka!

El Zoominario: How do we tell the time of macroevolution? -- Gustavo Ballen YouTube video by SolisLemus-lab

This outreach talk from last year just came out. Huge thanks to Claudia Solis-Lemus for inviting me to El Zoominario. www.youtube.com/watch?v=9qdL...

eu quero SITES das coisas, com contato via e-mail e telefone, especialmente lojas, serviços etc e não perfil de Instagram com preço inbox

also quero tutoriais e análises em escrito, que eu possa dar um control f, não em video que tu fica caçando o trecho de 5 segundos que te interessa

Our paper (with @sreinales.bsky.social) finally out today in the Evolutionary Journal of the Linnean Society. It feels like a birthday present 🤪 academic.oup.com/evolinnean/a...

It's not possible to use continuous in MrBayes at the moment despite the confusing information regarding this over the internet (been there some years ago). That's work in progress by Chi Zhang, so eventually it will be available.

The tragic landslide in Blatten gives me the excuse to tell you the story of how we found out Ice Ages existed. It's a cool story and the most important bit is rather similar to what's happening now.

Fascinating thread! Thank you!

“Massive numbers of students are going to emerge from university with degrees, and into the workforce, who are essentially illiterate…Both in the literal sense and in the sense of being historically illiterate and having no knowledge of their own culture, much less anyone else’s.”

Happy to share that my PhD paper published in Systematic Biology. My paper explores the #Asymptotictheory of Bayesian rate model selection and explore how misspecified calibrations can affect this. Also test rate model selection with large #Phylogenomes
