Ecological explanations for species coexistence assume that species’ traits, and therefore the differences between species, are fixed on short timescales. However, species’ traits are not fixed, but can instead change rapidly as a consequence of phenotypic plasticity. Here we use a combined experimental–theoretical approach to demonstrate that plasticity in response to interspecific competition between two aquatic plants allows for species coexistence where competitive exclusion is otherwise predicted to occur. Our results show that rapid trait changes in response to a shift in the competitive environment can promote coexistence in a way that is not captured by common measures of niche differentiation.

表型可塑性促进物种共存
物种共存的生态学解释假设物种的特征以及物种之间的差异在短时间内是固定的。然而，物种的性状不是固定的，而是可以由于表型可塑性而迅速变化。在这里，我们使用实验-理论相结合的方法来证明，响应两种水生植物之间种间竞争的可塑性允许物种共存，否则预计会发生竞争排斥。我们的研究结果表明，响应竞争环境变化的快速特征变化可以促进共存，而这种方式无法被利基分化的常用措施所捕获。
