Competition dynamics in long‐term propagations of Schizosaccharomyces pombe strain communities

Abstract Experimental evolution studies with microorganisms such as bacteria and yeast have been an increasingly important and powerful tool to draw long‐term inferences of how microbes interact. However, while several strains of the same species often exist in natural environments, many ecology and...
