论文摘要
我们根据理论模型显示，惯性如何在被捕食者追逐时在猎物群的生存动力学中起关键作用。随着猎物和捕食者的不同质量，出现了各种逃生模式，例如盘旋，追逐，操纵，分为亚组，并合并成一个单一的群体，类似于自然界中观察到的逃生轨迹。此外，我们发现从非生存的过渡到捕食者质量增加的猎物群生存。过渡状态也对猎物质量的变化敏感。 Further, the analysis of the prey group survival as a function of predator-to-prey mass ratio unveils the existence of three distinct regimes: (i) frequent chase and capture leading to the non-survival of the prey swarm, (ii) an intermediate regime where competition between pursuit and capture occurs, resembling an arms race, and (iii) the survival regime without the capture of prey.有趣的是，我们的研究表明，有效的捕食者质量比存在有效的捕食，这证实了现场研究。
We show, based on a theoretical model, how inertia plays a pivotal role in the survival dynamics of a prey swarm while chased by a predator. With the varying mass of the prey and predator, diverse escape patterns emerge, such as circling, chasing, maneuvering, dividing into subgroups, and merging into a unitary group, similar to the escape trajectories observed in nature. Moreover, we find a transition from non-survival to survival of the prey swarm with increasing predator mass. The transition regime is also sensitive to the variation in prey mass. Further, the analysis of the prey group survival as a function of predator-to-prey mass ratio unveils the existence of three distinct regimes: (i) frequent chase and capture leading to the non-survival of the prey swarm, (ii) an intermediate regime where competition between pursuit and capture occurs, resembling an arms race, and (iii) the survival regime without the capture of prey. Interestingly, our study demonstrates the existence of a favourable predator-prey mass ratio for efficient predation, which corroborates with the field studies.
