|28 March 2019||13:00||Laboratory strains of microbes have long been isolated from their muddy past. What predators, prey, or symbionts have they lost in this process? Are some of these former partners vital to the success or failure of apparently independent organisms? What would a wild collection where these ties are unbroken tell us? Here I use field-collected strains of the social amoeba Dictyostelium discoideum and their bacterial symbionts to explore these questions. Among the players are zombies, unculturables, chemical weapons, and complex evolutionary patterns. Even for microbes, we benefit from a return to the natural environment.
