There Are Many Ways to Find A Mate
Finding and choosing mates can be complicated, and many species have evolved diverse strategies to do this successfully. There are species where one male mates with multiple females but also species that pair bond for life. While many species have some sort of courtship and female choice, there are others where mating is a much “sneakier” affair. Variation in mating behaviors can also exist within the same species. In this talk, we will learn about some of the cool mating systems and strategies of the animal kingdom, and discuss some explanations about how and why this variation comes about in the first place.
Sunishka Thakur is a fifth year PhD student at UT Austin studying alternative male reproductive tactics in a swordtail fish. She explores how behavior, physiology and neurobiology can be shaped by different mating behaviors used by males to mate with females. She also studies how females respond to these alternative mating strategies and how it affects their behavior and physiology.

Genital Schmenital! The complexities of biological sex
What is biological sex? Is it our chromosomes? What’s in our pants? And if there’s only two sexes, why do so many animals exist outside this binary categorization? We’re taught two sexes exist and are significantly different from each other, but we also know biological sex is really messy and complicated. Throughout the animal kingdom, we see variation at chromosomes, physiology (hormones), gonadal structure and gamete production, body shape, and in behavior. These different organizational levels align and collide in as many ways as the colors in a kaleidoscope to give rise to the incredible sex diversity and variation we see in nature! Join Savvy for this all-ages talk about sex, from genomes to behavior, and the amazing diversity of animals existing contently in its complexities.
On November 13th, why don’t you come up to the lab—Brackenridge Field Lab—and see what’s on the slab—the big white projection screen? We’ll leave you shivering with antici—because it’s finally gotten a bit nippy outside, right? Like, fall is finally here—pation.
Savvy Cornett (they/them) is a PhD student at UT Austin studying how nutrition regulates reproductive physiology and behavior in a small freshwater fish, Páunco Swordtail (Xiphophorus nigrensis). This little fish has 4 different morphological sexes, who vary by their puberty timing, giving rise to variation in body shape and size and their mating behavior. Typically, nutritional status (how well fed an animal is) regulates reproduction: individuals reach puberty earlier when they intake more nutrients. Savvy’s research focuses on the evolutionarily ancient hormones regulating all this because how the reproductive hormones interact with the nutrition hormones, and vice versa, is poorly understood especially in this strange little fish.

Flora of the Living Dead: Resurrection Plants of Central Texas
Can plants rise from the dead like zombies? Let’s get into the spirit of Halloween season with a talk about some of the creepiest plants around– resurrection plants! Resurrection plants use a special ability called desiccation tolerance to survive extreme drought conditions that would easily kill most other creatures. This talk will highlight the ecology, evolution, and diversity of resurrection plants native to Texas, and explain what we know (and don’t know!) about how they manage to cheat death. Join Allison Hutt on October 9th to learn about resurrection plants!
Allison Hutt is a Plant Biology PhD student at UT Austin researching the ecology, physiology, and genetics of Texas native resurrection grass Tripogonella spicata (American five minute grass). Resurrection plants have the amazing ability to systematically dry themselves out during drought, allowing them to protect desiccated tissue in a state of dormancy. They can then rehydrate and resume normal function in a matter of hours after rainfall. Allison’s research focuses on the genetic and phenotypic variation in the Texas population of T. spicata, the physiological and genetic response to repeated bouts of desiccation and rehydration, and the ecology of resurrection plant communities in Central Texas.

September 11th, Rossana Maguiña-Conde
The Life of A Flower
Flowers are more than just beautiful structures—they are essential organs for plant reproduction. Nearly 90% of flowering plant species rely on animal pollinators to transfer pollen and ensure successful reproduction. In this talk, we’ll delve into the fascinating world of floral biology, exploring the diverse traits flowers have evolved to attract their pollinators. From color and scent to shape and timing, each characteristic tells a story of coevolution and ecological partnership. Join Rossana Maguiña-Conde on September 11th to learn about the life of a flower!
Rossana Maguiña-Conde is an evolutionary ecologist studying plant-pollinator interactions and plant reproductive systems. She is currently working as a postdoctoral researcher at the Stengl Lost Pines Biological Station surveying insects, plants, and soil after a wildfire. Dr. Maguiña-Conde received her PhD in Ecology and Evolutionary Biology from the University of California Santa Cruz, where she studied studied plant evolution and the role of pollinators on this process, focusing on how flowers evolved from a bee syndrome to a bird syndrome in the Neotropical spiral gingers in Costa Rica and Peru. She received her MS in Biology from the University of Missouri at St. Louis, where she studied the feeding ecology of nectar bats and their associated plants in cloud forests of Ecuador.

November 8, Colin Morrison
Plant and Animal Chemical Interactions
If atoms are the alphabet of life, then chemistry is the language that articulates those building blocks and gives them meaning in our lives. Behind every biological interaction—from mating signals to toxicity warnings—chemicals guide and shape possible outcomes.
Biologists study the variation of life using many different lenses. One tool that Colin uses in his research is the study of chemical ecology. Chemical ecology combines the fields of chemistry and biology to understand the causes and consequences of species interactions, distribution, abundance, and diversity. The promise of studying the chemistry of interactions between plants and animals stems from its potential to further our understanding of ecology and allow us to conserve nature in a holistic way. This month, Colin will show that chemistry is not an abstract study confined to research laboratories. Rather, it is a universal way of communicating that is responsible for the quantity and quality of plant and animal life on Earth. Colin Morrison is a PhD student in UT’s Ecology, Evolution, and Behavior program. You can read more about his work here: https://www.colinrmorrison.com/
Science Under the Stars is a free public outreach lecture series in Austin, Texas. The talk will be held outdoors at Brackenridge Field Laboratory, 2907 Lake Austin Blvd, Austin, Texas 78703. Here’s the schedule for this month’s event:
