Coral Bleaching: An On-Again-Off-Again Relationship

You’ve probably seen photos of completely white – or bleached – coral reefs. This bleaching happens as sea temperatures rise and can be deadly for corals. However, coral bleaching is really the “break-up” between the coral animal and tiny algae partners that live within their cells. Who are these partners? What causes this relationship breakdown? Why are some corals more resistant to warming seas than others? 

Through this talk, we’ll explore the relationship between corals and their algae and how scientists assess which reefs are most at risk.

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.

March 24th at 7:00pm: Francisco Llauger – “Through Claws and Scales: Reptiles, Conservation, and Iguanas of the Caribbean”
Reptiles are often among the most misunderstood animals walking, crawling, and slithering across our planet, but I’ve always seen nothing but fascinating beings that deserve our respect. I’ve led my life trying to study these creatures, and now I invite you to take that journey with me as we look at why these animals need our protection and look at a unique group of lizards nestled across the white sand beaches of the Caribbean-Cyclura, the most endangered lizards in the world!

April 21st at 7:00pm: Tristan Kubik – “Fermented fantasia: a leavenly evening sure to spoil you rotten!”
Planet Earth is infested with germs. They coat everything from the surface of our skin to the machines we use, and yes, even the food we eat. Some of these germs can make us sick, some disgust us with their putrid byproducts, while still others poison the very air we breathe. But hiding amidst these tales of illness and foul decomposition is a love story of epic proportions. Amidst the fray of villainous viruses, bad bacteria, and insidious fungi are a few unsung heroes and gifted culinary artisans. What happens when animals break bread with these good microorganisms? What possibilities are unlocked when two unlikely allies team up and turn terrible into terribly wonderful. Together we’ll embark on an unexpectedly delicious adventure. Join me for a leavenly evening as I relate one of the world’s lesser-known love stories, a tale of deliberate food spoilage we affectionately refer to as fermentation!

Thursday, October 3, 7pm: Megan O’Connell – “Bees go grocery shopping” 

How to Think, Dance, and Grocery Shop Like a Bee! We humans depend on bees for a lot more than we realize, but the bees need our help! Around the world bees are struggling to survive and now it is up to us to save them. One place to start is to understand which bees live around us (spoiler alert: it’s not just honey bees!), how they think, and what they like to eat. We’ll share all the interesting ways scientists gather this information, what we know so far, and most importantly, what you can do to help!

Thursday, November 7, 7pmTristan Kubik – “Clash of the Myrmidons” 

The Amazon rainforest is home to two unexpected titans. Leafcutter ants are peaceful, sedentary farmers responsible for processing huge volumes of tropical vegetation. They use their foraging material to cultivate obligate, fungal nurseries that cradle precious brood deep within their subterranean fortresses. Few organisms are courageous or capable enough to threaten mature leafcutter colonies, but the tank army ant is one of them. Tank army ants are nomadic, subterranean ant-killing machines. Their colonies can reach as many as several million and their hunger for leafcutters is insatiable. They flush out and overwhelm kilograms of prey every day with their numbers, mandibles, and venomous stings. And yet, leafcutter nests are not without defenses. Leafcutter colonies rapidly mount impressive responses to the alarming presence of tank army ant scouts including specialized soldiers, construction of barricades, and air-tight linear battlefronts. These two large, complex, derived societies clash in epic battles akin to the wars waged long ago by the Greeks and Romans with heroes just as notable as Hercules and Achilles. Such examples of social conflict are of great interest to systems science and parallels can be drawn to instances of immune systems vs disease, competing economies, and even human warfare. Join me for a night of bravery, sacrifice, and storytelling as I share my passion and knowledge about this riveting rivalry!

Thursday, December 5, 7pm: Allison Davis – “How to get a date: story of a clone” 

What do people, peacocks, and Poeciliids have in common? This Valentine’s day, they are all looking for dates! While tasty treats and fancy feathers may work for many animals, clones need some special dating advice. Join us this month to discover how an all-female clonal fish joins the dating scene!

The history and role of Brackenridge Field Laboratory at 52 years and counting

This slideshow requires JavaScript.

Have you wondered about how and why UT Austin keeps a field lab in the middle of the city? Come on out to this special, one-time event to learn about the history and discoveries made at Brackenridge Field Lab (BFL).

In the 1880’s, leaders of Austin attempted to industrialize with hydroelectric potential of the Colorado River. George Brackenridge provided capital, and land for a dam and a quarry that provided most the dam’s structure. The quarry, abandoned in 1893, and deep silt deposits that followed the dam’s collapse in 1900, were two disturbances that ultimately created a patch of urban nature dedicated as Brackenridge Field Laboratory in 1967. This backdrop explains how BFL, as a keystone resource that fostered UT’s premier graduate program in biology, could be created although never planned for this role by city or university leadership.

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:

  • 7:00 pm: Snacks, kids activities, and displays of local animals and plants discovered at Brackenridge Field Laboratory will be available.
