Across the animal kingdom, males and females of the same species are often locked in a battle of the sexes. The instigator is evolution itself. It drives them to develop weapons, tactical tricks and defensive maneuvers that aid in an animal's fight to pass its genes on to a new generation.

Biologists at The University of Texas at Austin have discovered three new species of groundwater salamander in Central Texas, including one living west of Austin that they say is critically endangered. They also determined that an already known salamander species near Georgetown is much more endangered than previously thought.
In many non-monogamous species, females provide all or most of the offspring care. In monogamous species, parental care is often shared. In these frogs, parental care includes transporting tadpoles one by one after hatching to small pools of water. In the non-monogamous strawberry poison frog (Oophaga pumilio, left) moms perform this task; however, in the monogamous mimic poison frog (Ranitomeya imitator, right) this is dad's job.

Why are some animals committed to their mates and others are not? According to a new study led by researchers at The University of Texas at Austin that looked at 10 species of vertebrates, evolution used a kind of universal formula for turning non-monogamous species into monogamous species — turning up the activity of some genes and turning down others in the brain.
It's been a big year for Texas Science, with news about research, new discoveries, technological advancements and awards making headlines around the world. Here are a few UT Austin science stories that made the news in 2018.
Whether you're looking for a gift for a science enthusiast or proud Longhorn in your life, or you're just seeking your next relaxing read, this roundup of recent books by or featuring members of the Texas Science community will come in handy.
Túngara frog females prefer the more complex mating calls of urban males.
Urban sophistication has real sex appeal — at least if you're a Central American amphibian. Male frogs in cities are more attractive to females than their forest-frog counterparts, according to a new study published in Nature Ecology and Evolution.

If you encountered an elephant bird today, it would be hard to miss. Measuring in at over 10 feet tall, the extinct avian is the largest bird known to science. However, while you looked up in awe, it's likely that the big bird would not be looking back.

The National Science Foundation has awarded a team of four researchers, including University of Texas at Austin biologists Howard Ochman and Mark Kirkpatrick, approximately $2 million over three years to classify the entire microbial world into genetic, ecological and functional units. The researchers also aim to understand how diversity originates and to analyze the genetic basis of functional and ecological differences between emerging species.
Over the last six years, faculty, staff and students from across the College of Natural Sciences have submitted hundreds of images from their scholarly research for our annual Visualizing Science competition, and these images have been viewed by tens of thousands of people. The submitted images, often beautiful and stunning, are the ones that spoke to their creators, inspiring and informing them as they followed their scientific passions.
