论文摘要
我们讨论了一种新型的方法，用于单个物种种群的基于随机的个体建模。个人的剩余生命是由个人剩下的一生而区别的，这些寿命是由时间不可分割的时间与个人的营养历史之间的相互作用所控制的。食物有限的环境会引起种内竞争，因此培养基的承载能力可能是有限的，通常会模仿物流增长的定性特征。还可以通过适当更改所涉及的少数参数来获得固有的非逻辑行为，从而构成了各种动力学特征。获得了一些分析结果。除了观察到的丰富现象学之外，我们期望我们模型的可能修改可能占集体人口增长现象的更广泛范围。
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.
