Recent studies have demonstrated that rapid contemporary evolution can play a significant role in regulating population dynamics on ecological timescales. Here we identify a previously unrecognised mode by which rapid evolution can promote species coexistence via temporal fluctuations and a trade‐off between competitive ability and the speed of adaptive evolution. We show that this interaction between rapid evolution and temporal fluctuations not only increases the range of coexistence conditions under a gleaner‐opportunist trade‐off (i.e. low minimum resource requirement [R^*] vs. high maximum growth rate) but also yields stable coexistence in the absence of a classical gleaner‐opportunist trade‐off. Given the propensity for both oscillatory dynamics and different rates of adaptation between species (including rapid evolution and phenotypic plasticity) in the real world, we argue that this expansion of fluctuation‐dependent coexistence theory provides an important overlooked solution to the so‐called ‘paradox of the plankton’.

快速进化促进了依赖波动的物种共存

最近的研究表明，当代的快速发展可以在调节生态时标上的人口动态方面发挥重要作用。在这里，我们确定了一种以前无法识别的模式，通过这种模式，快速进化可以通过时间波动以及竞争能力和适应性进化速度之间的权衡来促进物种共存。我们表明，快速演化和时间波动之间的这种相互作用不仅增加了在机会主义取舍者之间的共存条件的范围（即最低资源需求低[ R ^*]相对于最高增长率而言），而且在没有经典的拾荒者-机会主义权衡的情况下也能稳定地共存。鉴于现实世界中存在振荡动力学和物种之间不同适应率的趋势（包括快速进化和表型可塑性），我们认为这种依赖于波动的共存理论的扩展为所谓的“悖论”提供了一个重要的被忽视的解决方案浮游生物”。
