一个简单的基于个体的有限资源人口增长模型

A simple individual-based population growth model with limited resources

Luis R. T. Neves, Leonardo Paulo Maia

摘要:

我们提出了一种基于个体的单物种种群随机建模的新方法。个人的区别在于他们的剩余寿命,这是由无情的时间运行和个人的营养历史之间的相互作用调节。一个食物有限的环境诱导种内竞争,今后的承载能力的媒体可能是有限的,往往模仿后勤增长的质量特征。固有的非逻辑行为也可以通过适当地改变所涉及的几个参数来获得,从而构成各种各样的动力学特征。得到了一些分析结果。除了观察到的丰富的现象学,我们预计,我们的模型可能的修改可能会解释更广泛的集体人口增长现象。

英文摘要:

We address a novel approach for stochastic individual-based modelling of a single species population. Individuals are distinguished by their remaining lifetimes, which are regulated by the interplay between the inexorable running of time and the individual's nourishment history. A food-limited environment induces intraspecific competition and henceforth the carrying capacity of the medium may be finite, often emulating the qualitative features of logistic growth. Inherently non-logistic behavior is also obtained by suitable change of the few parameters involved, composing a wide variety of dynamical features. Some analytical results are obtained. Beyond the rich phenomenology observed, we expect that possible modifications of our model may account for an even broader scope of collective population growth phenomena.
