UT Spring 2022 Bee Competition
USDA Photo by Jack Dykinga Bring us the first Travis County mason bee of 2022, you’ll win a native Osmia bee house! Rationale: One measure of our changing climate is the shifting dates of emergence of our earliest spring flowers and insects. As Texas warms, some of our local bees may start coming out earlier in the year, and the Biodiversi...
Meet Stengl-Wyer Fellow: David Ledesma
David Ledesma is one of our 2021 Stengl-Wyer Fellows. With his advisor Dr. Melissa Kemp, he studies the responses of herpetofauna (non-avian reptiles and amphibians) to environmental changes, and the long-term responses of herpetofauna over the last 21,000 years. As part of the Stengl Wyer Endowment, the Stengl Wyer Fellows Program supports ye...
What We Talk About When We Talk About Snakes
What comes to mind when you imagine a snake? A rattler hissing and shaking its tail, ready to strike? A coral snake and the common identification rhyme “Red touches black, venom lack. Red touches yellow, kill a fellow”? Do you coil (pun intended) in fear? You’re not alone. Fear of snakes ranks in the top phobias for adults. This fear is called “oph...
Stengl-Wyer REU Program: supporting undergraduates in the natural sciences
Jenifer Dubon (left) and Jaylin Knight (right) The Stengl-Wyer Endowment is the largest endowment in the history of the College of Natural Sciences. It supports UT Austin’s programming in ecology and biological research, with a focus on the study of the diversity of life and interactions between living things and their natural environments...
Eel. It's what's for (Thanksgiving) dinner.
Illustration: Nicole Elmer Ah, Thanksgiving. We visit family, for better or for worse, slave for hours in the kitchen, gorge ourselves on football, and gather around a table to feast on a big fat roasted...eel? Historians agree that the very first Thanksgiving dinners had not only the ubiquitous turkey, but other fowl, venison, and yes, ee...All things creepy: parasitism, pt 5, crypt keepers

Talk about a nightmare of a roommate.
Imagine yourself to be a larvae of gall wasp, the species Bassettia pallida more specifically. You are inside the gall of an oak tree, a gall that... All things creepy: parasitism pt 4, mite pockets

Pockets are pretty cool things. We put our belongings in them, warm our hands on cold days in them. Some lizards have them too, but they aren’t storing cell phones in them. Chiggers live in these pockets, although sometimes a tick finds its way in there too.
Chiggers are... 
All things creepy: parasitism pt 2, the corpse lily

Because it t...
All things creepy: parasitism pt 1, mermithids and earwigs
This is a mermithid found in an Asian Hornet. (Wikicommons photo: PeerJ, 2015) In the spirit of Halloween and all that is spooky, we are doing a series of short blogs on parasitism! In biology, parasitism at its most basic level is where one species benefits at the expense of its host. The parasite does not always kill its host, but when it does...
A Lizard in Winter
With the weather finally cooling, I think about the upcoming winter. Usually, it’s the most beloved Austin season for me as I can go outside comfortably without the aid of mosquito repellent, for about a month anyway. This year however, I wonder about the next season with some trepidation. Most of us here in Austin right now remember winter storm U...Meet Stengl Wyer Scholar: Liming Cai
Liming Cai is one of our 2021 Stengl-Wyer Scholars. She is a systematic biologist broadly interested in the study of phylogenetics and evolutionary genomics of plants. Her research integrates fieldwork, herbarium collections, and genomic analysis to characterize the patterns and drivers of biodiversity. As part of the Stengl Wyer Endowment, th... 
Pets as Invasive Species: Fish Gone Wild
by Nicole Elmer and Adam Cohen, Ichthyology Collection Manager Illustration: Nicole Elmer Pet fish may not purr and curl up in your lap or bark when they see you, but because of their colors, anatomy, and behaviors they can be interesting and beautiful to observe in their aquariums or backyard ponds. But sometimes their owners decide...Through the Herbarium Cabinet: a Student View of the Billie L. Turner Plant Resources Center
by Sarah Hunter
This summer, through the ongoing haze of the COVID-19 global pandemic, I had the unique opportunity to explore the inner workings of the Billie L. Turner Plant Resources Center at UT. The Herbarium Curation Summer Graduate Fellowship program allowed me three months of hands-on training in the varied aspects of herbarium curat... 
A Case for Eels

With its high ceilings displaying quotations in gold paint, to the massive chandeliers, some have likened it to Hogwarts, the fictional British boarding school of magic in J.K. Rowli...
Pets as Invasive Species, an Introduction
Lucy (back) and Olive (front), two out of three of the author's feline invasive species. Humans have pets for lots of reasons. Companionship, protection, admiration of the animal’s beauty, an excuse to get outside for a walk. As much as we don’t want to hear it, our beloved Fido or Snowball, when mismanaged, can become invasive and threaten biod...History of UT Herpetology, Part 2: Mike Ryan's Work on Amphibian Communication

Herpetology at UT really kicked into gear when William Frank Blair arrived in 1946. Our first blog in this series looked at his influence on herpetology research and the Herpetology Collection. Here, we’ll review some of Blair’s work on frog communication, and how this focus carried into the presen... The Delicate Unseen World
A small example of groundwater species. (Gilbert & Culver, 2009, Freshwater Biology)
When we think about biodiversity, we often imagine life on ground, in the sea and air. Rarely do we think about biodiversity being in places we can’t see.
Beneath our feet, there are water sources with vast amounts of life, species being discovered, and spec... 
Featured Species: Slenderhead Darter (Percina phoxocephala)
by Melissa Casarez and Adam Cohen (Ichthyology Collection) Illustration: Joseph Tomelleri The Slenderhead Darter occurs throughout the Mississippi River basin, and only exists in Texas in tributaries of the Red River. It was first documented in TX in 1994 by UT biologists Laurie Dries and David Hillis in Sanders Creek, a...
Saving Water Damaged Species
by Viv Shu (undergraduate Museum Studies Certificate student and Sustainability major) Living plants need water to survive, but dried museum specimens of plants are exactly the opposite! The Billie L. Turner Plant Resources Center houses more than 1,000,000 such herbarium specimens in the Main Building. This 85+ year-old landmark, also known as the...
