History of Herpetology, Part 4: expanding research and collections
Texas Memorial Museum, shortly after its construction. In this next blog in our UT herpetology history blog series, we’ll be looking at the growth of herpetology research faculty in the 1980s and 1990s, as well expansion of the Herpetology Collection curatorial staff. Let’s start with a curatorial perspective and the Texas Memorial Museum...
Dr. Eric Pianka (1939-2022)
Photo: Larry Gilbert Dr. Eric Rodger Pianka was an evolutionary ecologist of enormous influence who spent his life studying lizards. Nicknamed “The Lizard Man,” his research covered a broad range of topics pertaining to the ecology, biology, and evolution of lizards, including rarity and responses to fire. His work contributed to the under...
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...
History of UT Herpetology, Part 3: Eric Pianka, the "Lizard Man"
Pianka in his office. Eric Pianka hasn’t earned the nickname “Lizard Man” for nothing. His lifelong work with lizards started as a childhood fascination for them, and eventually made him one of the world authorities on lizard ecology. But with 150 publications and a career spanning over half a century at UT, maybe Pianka should have a few ...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... 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... 
It got really cold. What does that mean for Texas biodiversity?
The February winter storm “Uri” saw temperatures drop into the single digits and stay below freezing for days. The last time Austin had single digit temperatures was in 1989, the year the Berlin wall fell, Indiana Jones and the Last Crusade came out, and Taylor Swift was born. So, yeah. It’s been a while. Uri not only caused havoc for Texans and ou...History of UT Herpetology, Part 1: The Early Decades
Look close! There's a Texas Spiny Lizard there. (Photo from Field Studies of the Behavior of the Lizard Sceloporus spinosus floridanus)
When UT became an official university in 1883, a biology program, much less a Herpetology Collection, was not on the agenda. It didn’t mean there were not some advocates pushing for physiology and botany c... 
UT’s Non-Digital Biodiversity Specimens Join the Global Digital Revolution
The prestigious journal BioScience just released "Natural History Collections: Advancing the Frontiers of Science," a compilation of recent natural history collection-related papers that sheds light on the importance of digitizing and publishing collections data, and the substantial obstacles confronting collections staff working on that. This come...BACKYARD BIODIVERSITY: Cliff Chirping Frog

The Cliff Chirping Frog is an elusive creature. Nocturnal and about the size of a quarter, they are more easily heard than seen.
There are actually three species of Chirping Frog in the genus Eleutherodactylus in Central Texas. There is Eleutherodactylus marnockii. They are native and their range is central ... BACKYARD BIODIVERSITY: Texas Spiny Lizard

If the Green Anole is the showy lizard presence in a garden, scampering around while flaring its red dewlap, the Texas Spiny Lizard is the opposite, typically shy, and well-camouflaged agai... BACKYARD BIODIVERSITY: Mediterranean gecko

Mediterranean gecko? What? But we’re in Texas!
While these are an Old World species, native to Southern Europe and North Africa, Mediterranean geckos have been introduced to many areas of the world, including Texas. They are common around Austin. You’... BACKYARD BIODIVERSITY: Green Anoles

With more time than usual at our homes, and the weather not searing hot yet, it’s a great opportunity to get outside and become familiar with the species we have in our own backyards! The Green Anole (Anolis carolinensis) is a common lizard not difficu... Texas Alligator Lizard

The Texas Alligator Lizard (Gerrhonotus infernalis) is the largest lizard with limbs in Texas, exceeded in length only by Slender Glass Lizards, which are legless. It is also one of the largest alligator lizards in the world. Adults are about 16”-18” in length and endemic to the central... CAMPUS BIODIVERSITY: Gulf Coast Toad (Bufo valliceps)

While it might be easy to assume we don’t have toads on campus, the Gulf Coast Toad (Bufo valliceps) is one species that does live here. Waller Creek is a one place to see them, in addition to planters where they hide, or on sidewalks at twilight to consume the insects that are att... CAMPUS BIODIVERSITY: Red-eared sliders

They’re out. Stacks of them. Sometimes piled on top of each other like bricks, feet extended, much to the delight of students and visitors to the UT turtle pond. These campus charmers are turtles commonly known as “red-eared sliders,” or Trachemys scripta elegans.
The “red” come... What's In a Name? Tummy Toads, Gastrophryne olivacea
Photo: Stanley Trauth 2007 (wikipedia)
A few years ago, I built several ponds near my house at the Double Helix Ranch, hoping that frogs would colonize them and I could enjoy the sound of frog calls outside my window. Several different species have come and bred there including Strecker's Chorus frogs (Pseudacris streckeri), Grey ... Field Herpetology Class Meets the Spot-tailed Earless Lizard

The Spot-tailed Earless Lizard (Holbrookia lacerata) is a small (70 mm snout-vent length), enigmatic lizard historically found across much of the Edwards Plateau, parts of the Permian Basin in west Texas, and parts of the south Te...
