@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.

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

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.

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.

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.
