Trait Evolution of Fitness, Fitness Diversity, Mean Colony Size and Colony Size Diversity in 12 Independently Evolved Microcosms after 1000 Generations (Comparison between Ancestor and Derived).

a)<p>Relative Fitness as determined in competition with the ancestor, by definition the relative fitness of the ancestor is 1.</p>b)<p>Fitness variance determined as the CV* of relative fitness of individual colonies isolated from a microcosm.</p>c)<p>Colony size diversity is assessed as CV* of colony sizes within a microcosm.
