November 12th, Tristan Kubik

Planet of the Insects

Please note that for this event, both the lecture and Q&A will be live and NOT recorded.

If you don’t like insects, then you’re living on the wrong planet. Earth is likely home to over ten million species of insects. Compared to the 5,000 or so mammal species and the 20,000 or so plant species, insect biodiversity vastly overshadows all other life on our planet. Furthermore, there are close to 10 quintillion insects estimated to be alive this very second. That’s more than 111 million creepy crawlies for every single one of the 9 billion humans alive today. Insects eat everything, do everything, and without them, life on land could not exist. Insects are important pollinators, they take care of life’s waste and dead organic material, and support every terrestrial ecosystem they occur in. But not all insects are allies. Insect pests are our number one competitor for food, blood-sucking insects have killed more humans than all the wars, famines, and natural disasters combined, and bugs constantly invade our homes and spoil our goods. So why are insects so successful? What has driven their massive diversity? How old are insects? And what are some of the ways we humans have figured out how to coexist with the true overlords of planet Earth? Join me, Tristan Kubik, a zany entomologist, as I introduce you to the marvelous microcosm of insects and show you that, contrary to what we would like to believe, insects truly are the dominant form of life on planet Earth. 

Science Under the Stars has gone virtual! This semester all SUTS activities will be online, but we encourage you to participate outdoors under the stars in your backyard! (If wifi allows for it, of course.) November’s schedule is as follows:

  • November 5th: Links to the kids activities and live online lecture/Q&A will be posted here and as an event on our Facebook page.
  • November 12th, 7:00pm CST: Live online lecture and Q&A with the speaker!

Science Under the Stars is a free public outreach lecture series based in Austin, Texas.

Neighborhood Science at Twin Oaks Branch Library

Science Under the Stars has expanded to include the Austin Public Library! At Neighborhood Science, previous SUTS speakers will present at different library branches around the city a couple times a month. Below are the dates and descriptions for this fall at the Twin Oaks Branch Library, 1800 S 5th St, Austin, TX 78704. All talks begin at 7pm.

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!

Neighborhood Science at Howson Branch Library

Tuesday, October 29, 7:30pm: Caitlin Leslie – “Sensory Superheroes: Extreme Animal Sensory Systems”

Like Superman’s X-ray vision or Daredevil’s radar sense, animals often have abilities  to perceive the world that humans could only imagine! They see colors that we are blind to, detect heat with their faces, send calls through the ground, and communicate with electricity. Come learn about some of the extreme sensory systems that exist in the animal world that allow them to hunt, navigate, and communicate in superhuman ways!

 

Tuesday, November 26, 7:30pm: Chase Rakowski – “Plankton: the little alien-like creatures that might save us all” 

Description coming soon!

Dr. Mark Moffett

Life Among the Ants

20130324-163109.jpg

Dr. Mark W. Moffett, research associate at the National Museum of Natural History, author of the book Adventures Among Ants, and protégé of E.O. Wilson, talks about the ways that modern humans are much more like ants than we are like chimpanzees. With our societies of millions, only certain social insects and humans need to deal with issues of roadways and traffic rules, public health and environmental safety, assembly lines and teamwork, market economics and voting, slavery and mass warfare. The talk will be illustrated with a few of the hundreds of images from Mark’s National Geographic Magazine stories, many of subject never seen before. The lecture will transport the audience around the world, to experience the fierce driver ants of the Congo, deadly bulldog ants of Australia, marauder ants of Asia, leafcutter ants of South America, and slavery ants of the USA.

Science Under the Stars is a free, monthly public outreach lecture series founded and organized by graduate students in the Section of Integrative Biology at University of Texas at Austin. Our goals are to host fun, informal science outreach events for Austin citizens of all ages, and give scientists a venue to share their work with the general public.
