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...
Mowing with Purpose: Managing Invasive Grasses at BFL
by Jason Lawson, Field Station Research Engineering/Scientist Associate Susie’s Meadow: a favorite landmark at BFL and one of the areas currently undergoing treatment for invasive grasses. The bucolic image of undulating grass fields in a summer breeze looks and feels uniquely Texan. It seems almost unbelievable that so many grasses t...The Power of Switchgrass: a Chat with Tom Juenger
Drought experiments with switchgrass using the rainout shelters in the Experimental Garden at BFL.
As a field station near the heart of Austin, Brackenridge Field Lab hosts important research by many UT faculty. Amongst them is Dr. Tom Juenger in the Department of Integrative Biology. He studies ecological and evolutionary genetics of local adap... 
Featured Species: Clown Beetle
Clown beetles, also known as Hister beetles, are a family (Histeridae) that contains over 3900 species. Their unusually glossy-but-sculptured surfaces and spiny appendages make them sought after by some collectors. They are found throughout the world, but not terribly common in Central Texas, which is why when Dr. Alex Wild, Curator ...
The Power of Poop
We all know poop. When it comes to plants, we might think of poop as the manure that gives our yards and crops a little pep and vigor. But poop is also one of the many ways plants propagate. Plants need a little help getting their offspring out into the world. They’ve evolved many methods to do that, and providing a nutritional bit of food to a pas...

Dr. Alma Solis is a research entomologist at the Systematic Entomology Laboratory (SEL) of the Agricultural Research Service (U.S. Department of Agriculture) and is located at the National Museum of Natural History, Smithsonia...
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 Spring Bee Competition
USDA Photo by Jack Dykinga We have a winner! Katie Elston is the winner of the UT Spring Bee competition. This competition was for submitting the first Travis County mason bee of 2021 to 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 spri...
Meet Stengl-Wyer Fellow: Colin Morrison
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...History of UT Entomology, Part 5: Sword's Grasshoppers
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... Brr...It’s Chilly Out There: How Animals Deal With the Cold

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, ... History of UT Entomology, Part 4: Screwworms

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 ... 
Meet Stengl-Wyer Scholar: Tom Bytnerowicz
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...
Shrubs of BFL: Catclaw Acacia
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....
Meet Stengl-Wyer Scholar: Shana Caro
Shana holding a superb starling (Lamprotornis superbus) As part of the new Stengl-Wyer Endowment, the Stengl Wyer Postdoctoral Scholars Program provides up to three years of independent support for talented postdoctoral researchers in the broad area of the diversity of life and/or organisms in their natural environments. Shana Caro is one o...
History of UT Entomology, Part 2: The Fly Years
John T. Patterson. “Sandy-haired and short of stature, he had a ready wit, a love of repartee, and the ebullient temperament we traditionally associate with the Irish people.” - Theophilus Painter in a 1965 memoir about him Part 1 explored the formative years for UT entomology and the focus on ants, with William Morton Wheeler and his stu...
BFL to the Rescue: Helping Instructors Teach During a Pandemic
All lined up and ready to learn. (Photo: Larry Gilbert) 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...
History of UT Entomology, Part 1: It Begins with Ants
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...
