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...

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.
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...

However...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 ... PART 1: Reflections on Isolation from the Middle of the Pacific Ocean
