论文摘要
在这项工作中，我们概述了基于两个差分方程的简单耦合系统，以及在两个类别中的属分配的几个偶联系统（如Rohde和Muller所使用的两个类别）。我们表明，尽管只有两个类别的分裂无法以短尺度捕获生物多样性演变的复杂性，但可以很好地描述广泛的趋势。我们还计算系统的绿色功能是一种定性描述天体植物学来源对随后的生物多样性演变的可能影响。
In this work, we outline a mathematical description of biodiversity evolution throughout the Phanerozoic based on a simple coupled system of two differential equations and on the division of genera in two classes - Short-lived and Long-lived types, as used by Rohde and Muller. We show that while the division in only two classes cannot capture the complexity of biodiversity evolution in short scales, broad trends can be described well. We also compute the systems' Green functions as a way to qualitatively describe the possible effects of intense perturbations of astrophyisical origin on the subsequent biodiversity evolution.
