论文摘要
在最初纯粹竞争性物种相互作用的捕食模型中，捕食的倾向通常被认为是相互作用物种相对形态学和生理特征的直接结果。 Here we explore a model in which predation ability is an independently evolving phenotypic feature, so that even when the relative morphological or physiological traits allow for predation, predation only occurs if the predation ability of individuals has independently evolved to high enough values.除了描述捕食的进化出现条件外，该模型还可以重现具有顶部捕食者的固定和非平稳的多级食物网，不一定具有大小优越性。
In models for the evolution of predation from initially purely competitive species interactions, the propensity of predation is most often assumed to be a direct consequence of the relative morphological and physiological traits of interacting species. Here we explore a model in which predation ability is an independently evolving phenotypic feature, so that even when the relative morphological or physiological traits allow for predation, predation only occurs if the predation ability of individuals has independently evolved to high enough values. In addition to delineating the conditions for the evolutionary emergence of predation, the model reproduces stationary and non-stationary multilevel food webs with the top predators not necessarily having size superiority.
