Hey spider peeps! 🕸️ Come join me at @unam_mx @ib_unam in the National Arachnid Collection. We’re looking for a systematist in Araneae 🕷️ Job App closes Monday 27th April, so apply soon!! www.ib.unam.mx/ibunam/Convo...

In case somebody finds them useful, I wrote these coalescent and popgen drift HTML simulators using @anthropic.com Claude.ai github.com/HernanHVM/Mu... github.com/HernanHVM/Wr... in Spanish #sistematicaunam #phylogenetics #stem #science

Hey @waynemaddison.bsky.social do we want it turned into a pickle? 🕷️🕸️

Part 2. This week in #sistematicaunam @ib_unam, an intro to the Coalescent. I wrote/debugged two htmls to demo Wright-Fisher drift and Kingman’s (see vid) models in #Spanish using @antropic.bsky.social Claude Sonnet with custom number of individuals sampled. #systematics #popgen #phylogenies.

We just released a blog post about something I'm very excited about: Great Docs. Post is in the *new* Posit Open Source site: opensource.posit.co/blog/2026-04... Great Docs is a #python pkg for creating beautiful Python package websites. We make it easy to use but also give you lots of options.

Reason 4 to attend the #IOCongress2026 #IOC2026: scoring all 8 spp of parrots/parakeets native to the Yucatán Peninsula 🇲🇽, such as this Red-lored Amazon (A. autumnalis) 🦜 #science #ornithology Pic taken in Cancún by instagram.com/alex_buess & instagram.com/avesmexicanas

This week in #sistematicaUNAM Susana Magallón led the BEAST2 by @arambaut.bsky.social @adrummond.bsky.social et al. tree calibration/dating lab by @trayc7.bsky.social using Malpighiales 🪴 (BTW, if screen log saved in 2.7.7, it won’t show it but you can open such file in your fave text editor.)

Preparing a #phylogenetic #bioinformatics #stats #birdos care package for my mentor, taking advantage a colleague from MN is here at @UNAM_mx You think he’ll like it?

Pretending to be #teamfish two days in a row… 🐠 🐟 It’s going great so far! cavefish.ib.unam.mx @ib_unam great science & ☕️ 🍪 🍌 🍎 #AIM2026 #cavefish #astyanax

New crown and stem bird swag 🦢 🦖

#ggtree by @yulab.bsky.social is fantastic for visualizing #phylo data in @rconsortium.bsky.social as it’s mounted on the @posit.co tidyverse. These are some phylopic.org homework plots from the #sistematicaunam class at @ib_unam real purdy ain’t ‘em?

Check out the elegant level of #phylogenetic #dataviz in @rconsortium.bsky.social & @posit.co my graduate padawans are pulling in the advanced @systbiol.bsky.social class @unam_mx! How neat is that!? I’d say pretty neat 😎📈📊

Birdo nerd peeps, it’s happening!!!! #IOC2026 in Merida Yucatán, Nov 30 - Dec 5. Early Bird (doiiii) just opened! iocongress2026.com #orno #ornithology

Is that Bayesian time of the year in #sistematicaunam @unam when we use the pain of non-convergence @nmkphylo.bsky.social experienced some years ago, that make for a great cautionary tale on parametric #phylogenetics

We also have a job search open for a researcher/prof in systematcs & malacology 🐌 🦪 🐙 🦑 @ib_unam! Here’s the info www.ib.unam.mx/ibunam/Convo... Malacólogues del mundo, venid a la @UNAM!

Come join me and other great colleagues at @ib_unam !! We’re searching for a new orno 🦅 🦢 🦉 systematics researcher/prof. for the largest bird collection in Mexico. See details herein www.ib.unam.mx/ibunam/Convo... Amigxs ornitólogxs! Habemus búsqueda de nuevx investigadorx! Apliquen!

Thanks for the comment, Hernán, we'll pass it over to the training team leads for consideration. In the meantime, you can access the materials from last year's edition of the course for free in the on-demand section of our training catalogue: www.ebi.ac.uk/training/mat...

😮 Nine years transitioning between postdoc’ing and Assit./Asoc. Professor/Researcher @ibunam.bsky.social but always phylogenetically ☕️ powered, courtesy of @systbiol.bsky.social 🤓😎

During 'Data science for life scientists' you will get hands-on training on: – APIs and Python – Data preprocessing and visualisation – Core machine learning methods – Deep learning approaches – Large language models Applications are open until 1 March 2026: www.ebi.ac.uk/training/eve... 🧬🖥️📊

Did u know u can fully run R, Python, Julia in your browser using @Google Colab ♾️? Can’t wait to try it in #systematics class @unam !!

Using my Spring Break to play arachnologist & collect some Habronattus jumping spiders 🕷️ from Hidalgo. Maybe @waynemaddison.bsky.social will take a gander.

🔍 Curious about what’s new in our scientific training catalogue? Every month our course list changes—new courses, new teachers, new collaborations. From palaeontology to programming, from ecology to statistics, we cover 12 different thematic areas.

Ha! Spoke too soon 😣 The TICR Perl scripts for #SNaQ and #PhyloNetworks broke down with my own data, so I had to modified them for the new ARM64 architecture. Make sure to install an appropriate Perl version and use Rosetta2. Also, deleting the server portion and saving MB log files don’t hurt 🙃💻

I'm recruiting a PhD student to join my lab at the University of New Orleans starting in Fall 2025. Research topics will focus on building and using phylogenies to study the diversification of birds, with an emphasis on Neotropical bird radiations. Contact me if interested.

#PhyloNetworks #SNaQ tutorial ready for Systematics class at #UNAM! However, teaching Julia+a little Perl+a little Bash on top of our mid-level R background would be too much for one session… Should I just turn this into a week-long post summer-break workshop?

According to my institute and the department of parking and general services at UNAM, I’m a trans woman and an ichthyologist. So be it #lgbt #teamfish 🏳️‍⚧️ 🐠

That’s right! Hennig was pro-Coalescent even before Kingman published his theory ~30 yrs after.

It’s high time for me to get a copy of @prosanta.bsky.social’s book, highlighted at IBUNAM’s 2025 Science Book Fair. 🐠🐟🦈

Nothing like the arrival of new stickers to motivate students into completing a series of daunting #Bayesian phylogenetic challenges in R at #UNAM Obvs they’re holographic.

Congratulations to Claudia Solís-Lemus! The Bassam Z. Shakhashiri Public Science Engagement Award recognizes one University of Wisconsin–Madison faculty member and one academic staff member for excellence in engaging the public with STEAM (Science, Technology, Engineering, Arts, and Math) research.

That’s right! We got some new murals (phase 1) in the National Bird Collection at Instituto de Biología #UNAM. How neat is that? I’d say pretty neat

My dear friends and colleagues at Instituto de Biología #UNAM led by Santiago Ramirez Barahona and Angela Cuervo just published this super paper in @sci.org on #ClimateChange and tropical could forests of Mesoamérica www.science.org/doi/10.1126/...

Convergent floral scent loss following transition to hummingbird pollination in spiral gingers (Costus). I had so much fun on this project with @kathleenmkay.bsky.social and Santiago Ramirez and am thrilled to see it published now in @MolBioEvol! academic.oup.com/mbe/article/...

Who’s ready for some Bayesian Inference teaching? #phylogenetics #UNAM

Plant #evol/#phylo peeps, come join us at UNAM! tinyurl.com/27jwrzne

Male Black-crested Coquette from this morning at Tapir Valley, Costa Rica. #birds #hummingbirds

About a month ago in our undergrad elective #SistematicaUNAM we taught the kids how to visualize alignments, calculate substitution model probabilities, and to visualize said models, all in #Rstats with ape, Phangorn and seqinr

Ready to crank up our #SistematicaUNAM undergrad class a lot with the latest in #phylogenetics

Gettin’ ready to do some science outreach. And nothing tops purdy hummingbirdos (we need a hummingbird emoji asap @apple)
