Pets as Invasive Species: Birds, Feathered Friend or Foe?
Monk Parakeet (Photo: Bernard Dupont-Creative Commons Attribution-Share Alike 2.0 Generic license) Birds are another beloved pet, adored for their plumage, their song, and for their interesting behavior. My own parakeets, Ernesto and Clyde, never fail to amuse with their head bobbing and love of stick-chewing. But like many pets that end u...
March of the Central Texas Butterflies
Butterflies never fail to fascinate young and old alike. They are the subject of countless paintings, poems, and for Professor James Glavan's (Head of the Costume Technology program in the Department of Theatre and Dance) class, Fabric Dyeing and Painting, they were the focus of an ambitious costume building project this spring semester. ...
A Northern Cardinal in North Austin
Male cardinal. (Photo: Gary Leavens - Creative Commons Attribution-Share Alike 2.0 Generic license) I awoke on a Sunday morning last week, started the coffee, then opened the curtains to my backyard. My usual habit, but on this Sunday, I had the surprise of seeing a female Northern Cardinal duck into the tight weave of a climbing rose about seve...

The COVID-19 pandemic has forever changed our lives. One thing that will probably never go away, for better or for worse, are remote meetings and online classes. But as some events begin to open up, the online formats are offering both in-person and remote experiences, thus opening access to audiences who could not have seen them otherwise.
One of ... 
Pets as Invasive Species: Cats
Cute but deadly. Author's cat, Hazel, poses in the sun. It’s not often an invasive species is crowned as ruler of the internet. That title goes to cats. From chatrooms with “Meowspeak,” to I Can Haz Cheezeburger, to Grumpy Cat (R.I.P), it’s funny to imagine fire ants or zebra mussels ever getting adorable memes made about them. With cats, ...

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
