Territorial battles in the aquarium tank: The molecular basis of social organization and behavior

Why are some species monogamous, and others polygamous? Hans Hofmann is trying to understand the ecological and molecular basis of divergent social organizations. Hes also trying to decipher the most basic molecular and hormonal mechanisms underlying social behavior in individuals. In dozens of aquarium tanks in his lab, African cichlid fishes jockey for turf, sometimes threatening to head-butt one another as they test territorial boundaries. The fish are ideal for studying social organization and behavior, because of their recent evolutionary radiation that has resulted in hundreds of species that behave differently. Hofmann will tell us what hes learned so far—and where the research is headed. Hans Hofmann, Ph.D. - Professor of Biology - University of Texas at Austin Hans Hofmann is a University of Texas biologist and a fellow at UTs Institute for Cellular and Molecular Biology. He was one of the first researchers to use cichlid fish to study how the social environment regulates brain and behavior. And he is a pioneer in the use of genomics and systems biology to analyze and understand these processes. He received his Ph.D. in biology from the University of Leipzig. http://cichlid.biosci.utexas.edu/inde...
