人工生命模拟是研究生态现象的重要工具，这些现象在自然环境中很难直接研究。最近的工作已经建立了声景作为一个生态学上的重要资源，它已被提出，动物发声声景内的分化是由种内通信的必要性。本文的实验在模拟声景中验证了这一假设，以验证种内交流作为声学生态位分化驱动因素的可行性。种内通信的影响被认为是一个重要的因素，在划分的声景的频谱相比，需要识别来自同种的信号不驱动信号的演变模拟。模拟物种间相互作用对声景的影响的方法被定位为开发人工生命体的工具，这些人工生命体可以居住在物理生态系统和声景中并与之相互作用。
Artificial life simulations are an important tool in the study of ecological phenomena that can be difficult to examine directly in natural environments. Recent work has established the soundscape as an ecologically important resource and it has been proposed that the differentiation of animal vocalizations within a soundscape is driven by the imperative of intraspecies communication. The experiments in this paper test that hypothesis in a simulated soundscape in order to verify the feasibility of intraspecies communication as a driver of acoustic niche differentiation. The impact of intraspecies communication is found to be a significant factor in the division of a soundscape’s frequency spectrum when compared to simulations where the need to identify signals from conspecifics does not drive the evolution of signalling. The method of simulating the effects of interspecies interactions on the soundscape is positioned as a tool for developing artificial life agents that can inhabit and interact with physical ecosystems and soundscapes.
