Influential People of Biodiversity: Billie Turner
Posing in 1970 with Perityle turneri (Asteraceae), one of many species named in Turner's honor. (Photo: Mike Powell) I first met Billie Turner in early 2016. That was when I’d started working on the Integrative Biology History project, and as Turner had a seven-decade career, I knew I had to interview him. With so much to cover, one meeting woul...
Sorting Fish
Those preserved specimens in natural history collections didn't get into their jars or drawers on their own. Quite a bit of work was involved, not only in the field, but also in the lab. This time lapse video from the Ichthyology Collection shows one of the first steps, sorting the specimens into jars.
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: Chase Smith
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. Chase Smith is one of three scholars starting at UT this year. Chase's researc...
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...Trout of Mexico's Sierra Madre
Young Dean, reading to go fishing with dad...
Like many others I'm sure, I found that working from home facilitated catching up on housecleaning, etc. Picking away at the long-standing task of re-housing old family photos, I came across one of me heading out trout fishing with my Dad.
It got me reflecting on what a big role ... Old Croone Day!
Croone as painted in 1680 by Mary Beale, one of the most prolific British portrait painters at the time.
Got plans on June 4th? Looking for something to celebrate? Might think about Old Croone Day. While it’s not official, the day honors a man who gave us a lot when it comes to the modern natural history collection.

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... Fish Collection Expands with TPWD
A quick overview of 15 years of UT Fish Collection growth and collaborations with Texas Parks and Wildlife
by Dean A. Hendrickson, Adam E. Cohen, Gary P. Garrett
As stated in the Biodiversity Center’s Collections webpage, the challenges for our collections are to: 1) “document biodiversity,” 2) “understand how biological processes... River Monsters, a Texas Edition
By Adam Cohen, Collection Manager and Melissa Casarez, Assistant Collection Manager (Ichthyology Collection)
We, in the fish collection, often find ourselves wading in deep, murky waters when out collecting around the state in creeks and rivers with steep banks and little chance for a quick escape, if necessary. During these times, we find it ... 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... FEATURED SPECIES: Rio Grande Chub (Gila pandora)
Illustration by Joseph R. Tomelleri
The only member of this minnow genus known from Texas, the Río Grande Chub, Gila pandora (Cope, 1872), lives in about a dozen sites in Río Grande tributaries of New México, and Colorado, and in one highly isolated, one mile-long section of a small stream in the Davis Mountains o...

The old riddle “Which came first, the chicken or the egg?” is not much of a riddle to biologists. The shelled amniote egg, which is familiar to many of us as chicken eggs, evolved about 325 million years ago. The wild ancestors of chickens, in contrast, only appe...
