SUMMARY:Biological Sciences Colloquium: Battle of the Organisms
DESCRIPTION:Please join us for this special colloquium event: Battle of the Organisms! Participating labs from Biological Sciences each chose a lab member to represent the organism they study. Presenters have 5-minutes to convince you that their organism is the greatest. You can expect unique\, organism-themed snacks\, persuasive presentations\, the occasional organism-to-organisms trash talk\, and a round of voting for best\, coolest\, and cutest organism. This is a great opportunity to learn about the diverse organisms we study in the Biological Sciences department. \nThe presentation will begin at 4:00 PM in Lapham Hall N101\, preceded by an informal reception from 3:45 – 4:00 PM.

SUMMARY:Biological Sciences Colloquium: Dr. Kyle Leistikow
DESCRIPTION:Dr. Kyle Leistikow\, research manager at Microbial Discovery Group (MDG)\, will present a talk about his work entitled\, “From Soil to Solution: Discovering Bacillus subtilis Peptides That Battle Biofilm-Forming Superbugs.” \nThe abstract is as follows: \n“Multidrug-resistant Staphylococcus auerus poses a critical challenge to both human and animal health\, largely due to its ability to form biofilms that protect it from antibiotics and promote resistance. To help combat this issue\, Bacillus subtilis\, a probiotic bacterium\, has emerged as a natural source of biofilm-disrupting compounds. After screening over 1\,000 Bacilius isolates\, we identified a unique strain\, B. subtilis 6D1\, that produces peptides capable of disassembling mature S. aureus biofilms and enhancing antibiotic sensitivity. This talk will explore the journey from soil to solution\, unearthing the powerful antibiofilm properties of Bacillus peptides and their potential to combat superbug infections.” \nThe presentation will begin at 4:00 PM in Lapham Hall N101\, preceded by an informal reception from 3:45 – 4:00 PM.

SUMMARY:Biological Sciences Colloquium: Dr. Mingzi Xu
DESCRIPTION:Dr. Mingzi Xu from the University of Minnesota will present a talk about her work entitled\, “The evolution and genomics of sexual signals and mating preferences.” \nThe abstract is as follows: \n“Sexual signals and mating preferences are key to sexual selection and speciation. The evolution of sexual signals and preferences involves trait divergence within each sex and coevolution between males and females. In addition\, signals and preferences are susceptible to environmental perturbations\, presenting a challenge to the stability of signaling systems. What genetic and genomic mechanisms govern the evolution of sexual signaling systems and maintain their stability against environmental perturbation is a crucial outstanding question in evolutionary biology. \nIn this talk\, I will present a study on the genetic basis of signal-preference coevolution in Laupala crickets\, where male song pulse rate and female preference for pulse rate have coevolved repeatedly. Using QTL fine mapping\, I have identified 3 pairs of co-localizing song and preference loci in the Laupala genome\, providing strong evidence for genetic coupling\, a long-dismissed hypothesis. I have also identified promising candidate genes that may pleiotrophically regulate male singing and female preference. I will then present new research in my lab on how environmental perturbations such as chemical pollutants and temperature fluctuations affect coordination between signals and preferences\, as well as neurogenomic mechanisms maintaining the stability of the communication system.” \nThe presentation will begin at 4:00 PM in Lapham Hall N101\, preceded by an informal reception from 3:45 – 4:00 PM.
