Tribble Lab & University of Washington Herbarium crew at #Botany2026!

Excited to share our latest study highlighted on the cover of @science.org 🥳Combining a 3D dataset representing 250 taxa spanning the whole Cenozoic, 3D modelling & printing and material testing; we deciphered the form-function relationship in the lower 🦷 of mammals www.science.org/doi/10.1126/...

I have officially started as Investigadora at the Instituto de Biología, UNAM. UNAM is a dream come true! Life is hectic! And I'm so excited for the immediate future, that will certainly involve liverworts, phylogenetics, and dogs! Follow my adventures here, ixchelgzlzr.github.io/es/

¿Te interesa postularte a una beca de Estancias Posdoctorales por México (SECIHTI) para desarrollar investigación en sistemática y evolución de hepáticas talosas complejas de México en el Instituto de Biología, UNAM? ¡Estoy buscando una persona interesada en preparar conmigo la propuesta!

From "contaminants" to data, the idea of using WGS bacterial reads to study liverwort associations started during a class I took during my PhD. Today it is published! Fun collaboration with @mickischill.bsky.social and @emehlferber.bsky.social. bsapubs.onlinelibrary.wiley.com/doi/full/10....

On Friday, my son stayed home from school because he had a sore throat and wasn’t feeling well. He went with my husband to his office for the morning while I handled our daughter. When he came back at lunch, he was not interested in eating, saying his throat hurt too much. 1/n

Jacob Suissa and I wrote a #book about #ferns! It's beautifully illustrated by the amazing artist Laura Silburn. Will be released in May and you can preorder from Amazon. We hope this book could help you forget all the bad things happening on Earth right now. More here: mailchi.mp/btiscience/f...

A couple weeks ago we crawled among the redwoods looking for bryophytes. I finally got a little time to write about it! It’s just a tiny bit liverwort-biased! ixchelgzlzr.github.io/CNPS_bryowalk

Interested in learning basic statistical concepts in Spanish during #Evol2025? This workshop is for you! @tropicalbotany.bsky.social and I are talking about it. Official registration in the meeting website. Thanks to @systbiol.bsky.social for the support (workshop in Spanish, bilingual materials.

Únete a nosotras en #Evol2025! No hay nada mejor que aprender sobre modelización estadística con la única e inigualable @roszenil.bsky.social-excepto hacerlo in español! //Join us!

Vittaria appalachiana (Appalachian Gametophyte). This neat fern is native to Appalachia and scattered areas beyond. Related to shoestring ferns, it exists only as a gametophyte in rock shelters and other sheltered habitat. #Fern #plants #nativeplants #Appalachia #botany #photography #nature

Today I led a public hike to see some bryophytes! It was an awesome experience! I’m so happy people are interested in looking at little plants 💚💚
