论文摘要
我们研究了初始条件和边界条件如何影响分散结构人群中的竞争动态和结果。这项研究是通过异质布朗虫模型的数值建模进行的，其中个体以多种扩散系数为特征，并竞争有限相互作用范围内的资源。我们观察到，如果不是在整个领域中随机分布，则最初将人口定位在一个小区域内，因此系统的动力学和固定状态差异很大。自然选择的结果取决于不同的竞争过程，波动和生物体的传播。
We investigate how initial and boundary conditions influence the competition dynamics and outcome in dispersal-structured populations. The study is carried out through numerical modeling of the heterogeneous Brownian bugs model, in which individuals are characterized by diversified diffusion coefficients and compete for resources within a finite interaction range. We observed that if instead of being distributed randomly across the domain the population is initially localized within a small region, the dynamics and the stationary state of the system differ significantly. The outcome of the natural selection is determined by different competition processes, fluctuations, and spreading of the organisms.
