摘要
Generalists and specialists are types of strategies individuals can employ that can evolve in fluctuating environments depending on the extremity and periodicity of the fluctuation. To evaluate whether the 演化 of specialists or generalists occurs under environmental fluctuation regimes with different levels of periodicity, 24 族群s of Escherichia coli underwent laboratory 演化 with temperatures alternating between 15 and 43 degrees C in three fluctuation regimes: two periodic regimes dependent on culture's cell density and one random (non-periodic) regime with no such dependency, serving as a control. To investigate contingencies on the 遺傳 background, we seeded our experiment with two different strains. After the experiment, growth rate measurements at the two temperatures showed that the 演化 of
