Neighborhood Science at Howson 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 Howson Branch Library, 2500 Exposition Blvd, Austin, TX 78703. All talks begin at 7:30pm. **These talks will be held outdoors, so bring a chair!

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!

Sarah Barfield – Permaculture principles in the sustainable food movement
Demand for sustainable, locally produced food is growing across the U.S. This movement has led to a resurgence in local farmer’s markets, urban gardening, and farms utilizing sustainable soil practices guided by permaculture principles. The results of these past and ongoing efforts to produce sustainable food have to led to incredible examples of abused land that has been restored to healthy and productive farm ecosystems. Come join us at Science Under the Stars this month if you want to learn about permaculture principles, soil biology and ecology, and more!

March 28: Collin 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/
