Extinction Caused by Mutual Antagonism between Strains E and F

<div><p>(A) At an initial developmental density of 10⁹ cells/ml, no spores survived starvation in mixed populations, but both competitors performed well in clonal isolation. Error bars indicate 95% confidence intervals.</p> <p>(B) Developmental phenotypes of E and F in pure culture (left and right, respectively) and in mixed competition (middle).</p>
