生态种群动力学的广义模型

Generalized modeling of ecological population dynamics

Justin D. Yeakel, Dirk Stiefs, Mark Novak, Thilo Gross

摘要:

在过去的几年里,一些作者使用广义模型的方法来研究食物链〈动〉<动>和食物网的动力学。广义模型接近随机矩阵模型的效率,同时与传统的基于微分方程的模型一样可直接解释。在这里,我们提出了一个教学介绍广义建模的方法。本介绍比以前的出版物更强调广义建模的基本概念。此外,我们提出了一个捷径,可以显着加快制定广义模型,并引入一个迭代程序,可用于完善现有的广义模型,通过整合新的生物学见解。

英文摘要:

Over the past years several authors have used the approach of generalized modeling to study the dynamics of food chains and food webs. Generalized models come close to the efficiency of random matrix models, while being as directly interpretable as conventional differential-equation-based models. Here we present a pedagogical introduction to the approach of generalized modeling. This introduction places more emphasis on the underlying concepts of generalized modeling than previous publications. Moreover, we propose a shortcut that can significantly accelerate the formulation of generalized models and introduce an iterative procedure that can be used to refine existing generalized models by integrating new biological insights.
