All things creepy: parasitism part 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

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...

Pets as Invasive Species: Fish Gone Wild

by Nicole Elmer and Adam Cohen, Ichthyology Collection Manager  Illustration: Nicole Elmer Pet fish may not purr and curl up in your lap or bark when they see you, but because of their colors, anatomy, and behaviors they can be interesting and beautiful to observe in their aquariums or backyard ponds. But sometimes their owners decide...

Through the Herbarium Cabinet: a Student View of the Billie L. Turner Plant Resources Center

Sarah 2 webby Sarah Hunter This summer, through the ongoing haze of the COVID-19 global pandemic, I had the unique opportunity to explore the inner workings of the Billie L. Turner Plant Resources Center at UT. The Herbarium Curation Summer Graduate Fellowship program allowed me three months of hands-on training in the varied aspects of herbarium curat...

Shrubs of BFL: Texas lantana

Photos: Larry Gilbert   This ubiquitous native low shrub is hard to miss. Part of the verbena family, those red, orange, and yellow blooms appear when the weather in Central Texas becomes close to unbearable. The scientific name is Lantanta urticoides, however it often gets confused with Lantana horrida, the name inspired by its strong odor...

With its high ceilings displaying quotations in gold paint, to the massive chandeliers, some have likened it to Hogwarts, the fictional British boarding school of magic in J.K. Rowli...
Pets as Invasive Species, an Introduction

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...

History of UT Herpetology, Part 2: Mike Ryan's Work on Amphibian Communication

TungaraFrog web A male Túngara frog. (Photo: Ryan Taylor) 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...
Saving the Guadalupe fescue

Saving the Guadalupe fescue

 Guadalupe fescue. (Photo: Carolyn Whiting) West Texas is known for arid landscapes reminiscent of old Western movies rather than cool damp mountains 6000 feet in altitude. But this is what areas of the Chisos Mountains are like, and where UT researchers have been surveying a rare grass, the Guadalupe fescue (Festuca ligulata). While once s...

The Delicate Unseen World

PhotoA webA small example of groundwater species. (Gilbert & Culver, 2009, Freshwater Biology) When we think about biodiversity, we often imagine life on ground, in the sea and air. Rarely do we think about biodiversity being in places we can’t see. Beneath our feet, there are water sources with vast amounts of life, species being discovered, and spec...

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

Sorting Fish

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.  
  And then...
