Happy World Mountain Day 🙂

Coming soon from @pedropezzi.bsky.social ! 

The frequency and importance of polyploidy in tropical rainforest tree radiations Schley et al. nph.onlinelibrary.wiley.com/doi/10.1111/...

@chukwumaemma.bsky.social Research explores an approach to clarify the phylo relationship & evol history of Alectra. Using seqdata with morph, habitat & climate traits, it aims to reveal diversification, adaptation & future ranges w/implications for conservation & understanding parasitic plant evol.

Thursday’s dinner will showcase UArk Herbarium/Prairie Pedagogy Pop-up Exhibition. It will highlight the UArk Herbarium support for educational and artistic work happening in the Oak Knoll Prairie. Artworks by Caite Ramos, Ellie Johnson, Mikki Young, Peter Brown, Mia Dixon, Kaylee Hutto and more!

@phylojennatics.bsky.social research focuses on macro and micro forces that can influence species abundance in Silene. She is using herbarium specimen data to build a genus phylogeny. Jenna successfully extracted DNA from a specimen from 1892!

Why is it important to press native plants? Find out on Nov 8th at the Fayetteville Public Library! @phylojennatics.bsky.social a PhD student in @maribethlatvis.bsky.social lab will be leading this event! See you there 🌱

Fieldwork highlights from Italy: to understand what a species is PhD student @rlsavage.bsky.social is taking a integrative approach using morphological, genomic & ecological data to determine what a species is in Rhinanthus @maribethlatvis.bsky.social and Emily Carter helped with the fieldwork

Updated tutorials for nQuack today. Want to predict ploidy level of sequence data? See this new tutorial on how to process and model data faster: mlgaynor.com/nQuack/artic...

We have several exciting events lined up for the 150th anniversary of the UARK herbarium! Check out all the events with this link: biology.uark.edu/herbarium/ev...

Master’s student @arisaemaguy.bsky.social focuses on the Arisaema triphyllum species complex. It has been subject to numerous taxonomic revisions over the past 200 yrs. Morgan is utilizing morphometrics, on both the macro & micro scales, to help herbaria distinguish between the species.

If you are or you know people on an #H1B, get in touch with your U international office to get guidance and know what you/they should/should not be doing. I just received the information below from #AAUP. Feel free to share and check in with your immigrant friends/colleagues. They are not doing ok.

Fieldwork in Brazil to understand how new plant species evolve? Pedro Pezzi @pedropezzi.bsky.social and Maribeth Latvis @maribethlatvis.bsky.social are taking a multi-pronged approach in Agalinis to understand morphological shifts and species interactions during rapid diversification

THRILLED to announce that my NSF "Closing the gap: The history of river connections with the formation of the isthmus of Panama and its impact on the evolution of plants in rivers" in collab w/Carlos Jaramillo at STRI and Caroline Strömberg at UW was awarded! Add for a PhD student+a postdoc to come🧵

In today's Poetry Clinic, I address the question of how to carry forest's quiet with us. For me, the best approach is writing: note-taking while I am in the forest quiets my mind, writing up the notes afterwards seals the memories. w/ a quote from Edwin Way Teale. poetryclinic.org/how-do-i-car...

Agalinis (Orobanchaceae) getting a little bigger? onlinelibrary.wiley.com/doi/10.1002/...

📢 Calling PhD students 📢 we want to hear from you! Help shape the future of PhD education. Take our survey to tell us all about your experiences https://go.nature.com/3FhzbVE

really cool new paper showing species across the globe are NOT moving upslope any more than you'd expect based on a null model www.science.org/doi/10.1126/...

Congratulations to the 2025 SHC Student Awardees! Undergrad Andrew Ruegsegger with Dr. Maribeth Latvis at U of Arkansas studying “Plant community assembly in an insular grassland biodiversity hotspot: microbial and environmental effects on phylogenetic and functional diversity of Ozark glades".

We were thrilled to host a series of Kaleidoscope Science events! We used screen printing as a medium to explore how multiple layers combine to enhance our understanding of biodiversity. We printed Agalinis fasciculata! @uarkherbarium.bsky.social

Congratulations to the NSF GRFP awardees! This was an especially competitive year because the number of awardees was down by 51%. To the students who didn't get it: my heart goes out to you. This was an especially competitive year. I hope this doesn't deter you from research.

If a student you know received an honorable mention for the NSF GRFP, encourage them to contact their Congressional representatives! 🧪

Made it to Serra do Cipó, Minas Gerais, Brazil for botanical adventures. I’ve missed this! @pedropezzi.bsky.social

Prairie Practice and Pedagogy gallery opening: UArk Fine Arts in collaboration with @uarkherbarium.bsky.social 🤝. Kids these days with their punk rock plant zines 🥲

Welcome back to UARK, Sarah J! Dr. Sarah Jacobs, U of A alum, was our dept seminar speaker this week. Assistant Curator of Botany and Howell Chair of Western North American Botany at @calacademy.bsky.social, Dr. Jacobs studies paintbrushes (Castilleja) & gave a fascinating talk about the group.

So here's a cool thing we're doing with the UA School of Art this weekend. Reception is Friday, March 14 at 6:00 at the sUgAR Gallery, in the lower level of the Pryor Center, 1 E. Center St., downtown Fayetteville. Camille Gros - sweet flyer!

@phylojennatics.bsky.social and @rlsavage.bsky.social, botanists and PhD students with the @maribethlatvis.bsky.social Lab in the Dept. of Biological Sciences at the @uarkansas.bsky.social recently taught students about botany, plant collecting, and biodiversity at the Holcomb Elementary STEM Night!

Hey! We’re looking for a woman in science who is actively promoted and supported women in biology to give a talk or lead a workshop. Let me know if you have any recommendations! #womeninstem

It's here and ahead-of-print at @asn-amnat.bsky.social ! 🎉 Our 22-page polyploid coexistence model is now available: doi.org/10.1086/734411 This work wouldn’t be possible without NSF support—including funding from an NSF GRFP, an NSF PRFB, and NSF DMS & DBI grants. @soltislab.bsky.social l

UARK is bustling today! Volunteers @dgwalt.bsky.social @auxarcwildflowers.bsky.social @staymoreark.bsky.social and grad student @arisaemaguy.bsky.social mounted plants and worked on insect mgmt, while local artist (and recent UA grad) Riley Moore came in to draw grasses.

Winter Schminter, we're going botanizing! Join @jenoglesplants.bsky.social & @andrewruegsegger.bsky.social for a hike at @nature.org 's Smith Creek Preserve. Cold weather won't stop us, but rain, snow, or ice will so find news and cancellation info at biology.uark.edu/herbarium/events.php.

The "database" being just an excel file named "Public Database_Release (1) (1).xlsx" is just objectively funny.

3 cheers for advocates! As we realize that scientists need to do more to unpack the value of science, we need to ... ... stop side-eying scientists who write in lay terms ... stop wishing that scientists would "just science" ... stop belittling scientists who meet the public where they are

A few mosses we saw growing on Ozark sandstone outcrops during a recent hike. UARK has uploaded all of the nearly 3,000 preserved #bryophytes (mosses, liverworts, and hornworts) in its collection to bryophyteportal.org.

Calling all students & early career members of the @botsocamerica.bsky.social and ASPT! Apply for the public policy award to travel to D.C. to receive science communication & advocate for federal support of scientific research! botany.org/home/awards/...

Now seems like a good time to say that anti-discrimination policies like DEI do not oppose merit-based hiring. They are intended to expand the pool of talent considered for jobs and hired based on merit. In the past organizations only hired a subset of the talent available because of discrimination.

Hey look! A Society for the Study of Evolution starter pack! Includes ESEB, ASN, and journals! Pls Re-skeet!

Hey there Blue Sky! We are WOCinEEB, an organization for women of color & non-binary people of color in ecology, evolutionary biology, & allied fields. We offer formal & informal mentorship programs for all career stages & a space for community positivity. Join us & find your people! wocineeb.org

I started gathering a list for REUs/Summer research opportunities for undergraduate students in Ecology/Conservation/Evolutionary Biology. Feel share to share with any undergraduate students who may be interested in participating in *PAID* research. docs.google.com/spreadsheets...

My occasional reminder to folks on tenure and promotion committees that there will be a cohort of people whose early careers were defined entirely by the pandemic and *waves vaguely* this nonsense, and it *will* impact their productivity. It can't not.

Hey friends. How's everyone's mental health this week?

First Plant Taxonomy lab of the semester!! Starting off with vegetative morphology basics Quote from student: “I didn’t realize plants were so complex”

My #plantsgiving totals: 49 species in 25 different families!

my #plantsgiving from a few years ago. Not as diverse as some, but it included some niche things from the upper Midwest

making my Intro Botany course participate in #plantsgiving a la @martinebotany.bsky.social for a classroom discussion. Tallies for next week! discoverandshare.org/2020/11/21/p...

Getting trolled in Plant Taxonomy for my pronunciation of "PECAN". I live in the South now...

The question has often been asked whether living organisms are organized in a continuum or whether they are discontinuous the answer is "both---and." The web of life projected through time... is a continuum... --- Jens Clausen 1951, Stages in the Evolution of Plant Species, pp 178-9.

Going to elevate a positive story: The latest issue of the Vasculum (@socherbcurators) features a wonderful collaboration @UArkansas between art and science-- using the UARK herbarium to convey space and time! herbariumcurators.org/wp-content/u... (pg 10-12)

This is so sad. The collections housed here are not just national treasures for Colombia, but invaluable treasures for the scientific community, and the world. I really hope that they can somehow get the money they need to save them.

We have to continue educating about the value of collections. These aren’t “dead plants”. Herbaria are our essential for understanding a changing planet.
