Natural history collection in the Department of Biological Sciences on the University of Arkansas campus, documenting the diversity and distribution of the plants of Arkansas and beyond since 1875. https://biology.uark.edu/herbarium/events.php
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!
@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.
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
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.
Last weekend, Burnetta Hinterthuer was awarded our Eric & Milanne Sundell Award to recognize the impact she has on native plants in Arkansas, including being a mentor to collections manager, @jenoglesplants.bsky.social. @andrewruegsegger.bsky.social president-elect of the ANPS planned the meeting.
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
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!

We're hosting a Kaleidoscope Science event this weekend! Join us Sunday, April 13 5:30-8:30 at the BISC Greenhouse, 518 S. Eastern Ave, Fayetteville.
Prairie Practice and Pedagogy gallery opening: UArk Fine Arts in collaboration with @uarkherbarium.bsky.social
🤝. Kids these days with their punk rock plant zines 🥲
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!

Thanks to the 30 who came to Smith Creek Preserve on Sat! @jenoglesplants.bsky.social & @andrewruegsegger.bsky.social led the group to Elise Falls, pointing out plants along the way. Highlights: Aplectrum hyemale & Tipularia discolor in leaf, Hamamelis vernalis & Erythronium albidum in flower.
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.
Entomology and Plant Pathology to Present a Professional Development Seminar Session Today
Very excited to introduce the newest genus of wild sunflowers, a tiny desert annual covered in dense wool and heads with just two small ray florets.

The most recent lecture I gave on Oak Origins at The Morton Arboretum was really nicely recorded and is available for free online. This is the fullest and cleanest version of the lecture I've given to date, with some new info.
I hope you enjoy it. Feel free to share.

Just giving a tour to some visitors and remembered this pandemic project: a Quarantine Public Library zine answering the question, What is an Herbarium?
Print, fold, cut, and you have a little book! Free to share.

Winter wins, for now... we're rescheduling this trip for Saturday, March 1 and hoping for favorable conditions!
***TRIP POSTPONED UNTIL MARCH 1***
Hey everyone! Major roads may be clearing as temps increase over the next couple days, but side roads and the steep trails in the narrow valley at Smith Creek are likely to still be dicey by this weekend. So we're postponing this trip until next Saturday, March 1.

Repair, before & after | Arisaema dracontium | 1869 | Ames, IA
Collector is unknown, but native Iowan F.L. Harvey likely brought this along when he was hired as faculty @ the U of A (then the Arkansas Industrial University). Thanks @llennodo.bsky.social for flagging this specimen!
Our unofficial mascot Sam the Dog relaxed today as her person, U of A senior Rowan Offutt, worked in the collection, long-time volunteer @llennodo.bsky.social digitized specimens, & UARK field technician @andrewruegsegger.bsky.social identified plants collected during field work last year.
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 Botany Hike @Smith Creek Preserve, February 22, 10 am to 1 pm. Sponsored by the University of Arkansas Herbarium & Arkansas Native Plant Society.
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.
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.
