论文摘要

我们确定一种生物空间模式形成的机制,当介导人群中的个体之间相互作用的信号具有脉冲特征时。我们的一般人群信号框架表明,尽管对于慢速信号动力学限制,对于模型参数的任何值都没有观察到模式形成,但对于快速限制,可能会发生模式形成。此外,在这些限制下,我们的框架分别减少了反应扩散和空间非局部模型,从而弥合了这些方法。

We identify a mechanism for biological spatial pattern formation arising when the signals that mediate interactions between individuals in a population have pulsed character. Our general population-signal framework shows that while for a slow signal-dynamics limit no pattern formation is observed for any values of the model parameters, for a fast limit, on the contrary, pattern formation can occur. Furthermore, at these limits, our framework reduces, respectively, to reaction-diffusion and spatially nonlocal models, thus bridging these approaches.
