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...

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...

Bring us the first Travis County mason bee of 2021, you’ll win a copy of the book “The Bees In Your Backyard”!
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 ye...
The Stengl-Wyer Endowment supports year-long fellowships for doctoral candidates pursuing dissertation research in the area of Diversity of life and organisms in their natural environments. Recipients will receive a 12-month stipend of $34,000, full tuition and fees, staff health insurance, and an allowance of $2,000 to cover research and trav...
Schistocerca lineata
In our last blog on the History of UT Entomology, we looked at the damage screwworm flies were causing to livestock until the Sterile Insect Technique was introduced. In this blog, we will be looking at another infamous insect responsible for massive damage to resources such as crops. We begin with some of the...

Cold weather brings big shifts in nature. In many places, water sources freeze, plants cease blooming and drop their leaves, and the ground is covered in snow. These conditions mean diminished resources for animals, ...

Few people want to be a screwworm fly (Cochliomyia hominivorax) for Halloween, but maybe this should be a valid costume choice as what they do is pretty horrifying. In the early to mid-20th century, this obligate parasite, often called just “screwworm” for ...
Fertilizing nitrogen fixing tree seedlings in a greenhouse experiment
Thomas Bytnerowicz is our third Stengl-Wyer Scholar this year. He studies the feedbacks between global change and nitrogen and carbon cycling. As part of the new Stengl-Wyer Endowment, the Stengl Wyer Postdoctoral Scholars Program provides up to three years of indepe...
This perennial shrub (Senegalia wrightii) grows 6-10 feet tall although some accounts say it can grow to triple this size. The lacey foliage is twice pinnately-compound and semi-evergreen. Pinnately-compound refers to a leaf that is divided into smaller leaflets and those leaflets are arranged along each side of the leaf's central stalk, or rachis....

It’s a hot late August afternoon. Classes have started for UT students, but this year things look a little different. Fifteen minutes from campus, at Brackenridge Field Lab (BFL), ecology students stand ready, six feet apart, notebooks in hand, masks covering their mouths and noses. D...
From Ants: Their Structure, Development, and Behavior (1910)
When UT opened its doors in 1883, biology was not part of the curriculum, despite that faculty at the time pushed for representation of botany and physiology. “The new State University organized in 1883 had more ambitions than resources,” wrote Geneticist and UT professor Clarenc...

Ripe berries on Beautyberry (Photo: Nicole Elmer)
Around this time of year, this shrub is difficult to miss. The normally inconspicuous green berries turn bright purple and become quite popular for wild bird and animal populations. This plant’s scientific name is Callicarpa americana, or better known as the Beautyberry or American Beautybe...
Cottonwood trees and willows are similar in many ways. They germinate through wind dispersion and colonize moist muddy areas exposed to full sun. Both are present in Brackenridge Field Lab, and the cottonwoods in particular have a close connection to the history of the field lab.

Cottonwoods (Populus deltoides) are one of the ...

In part one of our blog, the tawny crazy ants (Nylanderia fulva) were overrunning the native species at Estero Llano Grande State Park. Researchers at Brackenridge Field Lab had identified a microsporidian that could possibly control the population, but success rates were still very low.
When the resear...

In 2016, staff at Estero Llano Grande State Park knew something wrong. During night tours for visitors, they noticed many of the normally-seen species like scorpions were gone. They also had not seen many snakes or lizards common to the area. Then came sightings of blinded rabbits.
Turns out that this state ...
