"Social behavior and mutualism in the social amoeba
Dictyostelium discoideum and its bacterial symbionts"
Dr. Joan Straussman
Washington University-St. Louis
With microbial studies we can see how well theories of social behavior derived from organisms with brains apply to organisms where cell adhesion, receptors, and secretions prevail. Furthermore, we can test specific predictions of kin selection and mutualism using experiments, experimental evolution, and genomics. Here I explore the behavioral ecology of social amoebae, introduce some of the genes behind these interactions, and delve into some of the complex interactions between amoebae and bacteria. Are the bacteria a disease, a crop, or a weapon?
Joan Strassmann is Charles Rebstock Professor of Biology at Washington University in St. Louis where she has been since 2011. She was previously on the faculty at Rice University for 30 years. She received her Ph.D. at the University of Texas at Austin and her B. S. from the University of Michigan. In 2013 she was elected to the National Academy of Sciences. She is interested in the evolution of cooperation and the control of conflict in social and mutualistic systems, from social wasps and bees to microbes including Dictyostelium and bacteria.
