Fitness trade-off for beneficial mutations in different environments: a Relative exponential growth rate, with respect to the ancestor (marked with horizontal lines), for clones adapted to limiting nitrogen conditions on glucose limitation (0.01%). b Relative exponential growth rate, with respect to the ancestor, for clones adapted to limiting magnesium conditions on nutrient rich media of Lysogeny broth â– and glucose (0.1%) minimal media â–²
