论文摘要
正如通常指出的那样,生态系统很复杂。同样值得注意的是,无论是huygens夹带的简单模式还是洛伦兹对流的扭曲的混乱轨道,复杂的系统倾向于振荡。因此,振荡器的分析可能会深入了解生态系统的结构。该研究最流行的分析工具之一是库拉莫托耦合振荡器的模型。我们将害虫及其敌人系统及其在农业生态系统中进行,我们将该模型作为对该真实系统动力学的程式化的视野,以询问其实际自然历史是否反映在定性实例化的库拉莫托模型的动态中。该模型的出现是一系列同步组,通常与自然系统的子网相对应,具有上覆的嵌合结构,具体取决于振荡器偶联的强度。我们得出的结论是,库拉莫托模型提出了一个新颖的窗口,其中可能会出现有关生态系统结构的有趣问题。
Ecological systems, as is often noted, are complex. Equally notable is the generalization that complex systems tend to be oscillatory, whether Huygens simple patterns of pendulum entrainment or the twisted chaotic orbits of Lorenz convection rolls. The analytics of oscillators may thus provide insight into the structure of ecological systems. One of the most popular analytical tools for such study is the Kuramoto model of coupled oscillators. Using a well-studied system of pests and their enemies in an agroecosystem, we apply this model as a stylized vision of the dynamics of that real system, to ask whether its actual natural history is reflected in the dynamics of the qualitatively instantiated Kuramoto model. Emerging from the model is a series of synchrony groups generally corresponding to subnetworks of the natural system, with an overlying chimeric structure, depending on the strength of the inter-oscillator coupling. We conclude that the Kuramoto model presents a novel window through which interesting questions about the structure of ecological systems may emerge.
