Eco-evolutionary frameworks can explain certain features of communities in which ecological and evolutionary processes occur over comparable timescales. Here, we investigate whether an evolutionary dynamics may interact with the spatial structure of a prey-predator community in which both species show limited mobility and predator perceptual ranges are subject to natural selection. In these conditions, our results unveil an eco-evolutionary feedback between species spatial mixing and predators perceptual range: different levels of mixing select for different perceptual ranges, which in turn reshape the spatial distribution of prey and its interaction with predators. This emergent pattern of interspecific interactions feeds back to the efficiency of the various perceptual ranges, thus selecting for new ones. Finally, since prey-predator mixing is the key factor that regulates the intensity of predation, we explore the community-level implications of such feedback and show that it controls both coexistence times and species extinction probabilities.
生态进化框架可以解释某些特征的群落，其中生态和进化过程发生在可比的时间尺度上。在这里，我们研究了进化动力学是否会与猎物-捕食者群落的空间结构相互作用，在这种群落中，两种物种的移动能力有限，而捕食者的感知范围受到自然选择的影响。在这些条件下，我们的结果揭示了物种空间混合和捕食者感知范围之间的生态进化反馈：不同程度的混合选择了不同的感知范围，而感知范围又反过来重塑了猎物的空间分布及其与捕食者的相互作用。这种种间相互作用的新兴模式反馈到各种感知范围的效率上，从而选择了新的感知范围。最后，由于猎物-捕食者的混合是调节捕食强度的关键因素，我们探讨了这种反馈的群落水平的影响，并表明它控制了共存时间和物种灭绝的概率。
