标题： Far-ranging generalist top predators enhance the stability of meta-foodwebs

摘要： 识别食物网中的稳定因素是一个长期存在的挑战，对群落生态学和保护具有广泛的意义。 在这里，我们研究了具有远距离超级捕食者的空间解析的元食物网的稳定性，对于这些超级捕食者来说，整个元食物网似乎是一个单一的生境。 通过结合广义建模与主稳定性函数方法，我们能够有效地探索大量现实的多斑块元食物网的渐近稳定性。 我们表明，具有远距离顶级捕食者的元食物网比具有局部顶级捕食者的元食物网更稳定。 此外，尽管增加了食物网的规模，向系统中添加远距离的广谱顶级捕食者仍可能产生净稳定效应。 这些结果突显了顶级捕食者保护的重要性。 显示英文摘要

摘要： Identifying stabilizing factors in foodwebs is a long standing challenge with wide implications for community ecology and conservation. Here, we investigate the stability of spatially resolved meta-foodwebs with far-ranging super-predators for whom the whole meta-foodwebs appears to be a single habitat. By using a combination of generalised modeling with a master stability function approach, we are able to efficiently explore the asymptotic stability of large classes of realistic many-patch meta-foodwebs. We show that meta-foodwebs with far-ranging top predators are more stable than those with localized top predators. Moreover, adding far-ranging generalist top predators to a system can have a net stabilizing effect, despite increasing the food web size. These results highlight the importance of top predator conservation.
