论文摘要
人工生态系统提供了一种额外的实验工具，以支持竞争性排斥研究中的实验室工作，现场工作和理论发展。提出了一种基于时空代理模型的新颖应用，该模型模拟了两个不同内在生长速率的觅食物种，在稳定和季节性环境中争夺相同补充资源。这种实验方法提供了对环境，物种和个体运动的参数的精确控制。这些非平衡种群及其特征的详细轨迹将产生。潜在共存的狭窄区域在环境和内在的生长参数空间内被鉴定出来。确定了由局部空间动力学驱动的共生主义的一个例子。这些实验的结果是在现代共存理论和运动介导的社区大会中的研究中讨论的。确定了对可能的起源方案的限制。
Artificial ecosystems provide an additional experimental tool to support laboratory work, field work, and theoretical development in competitive exclusion research. A novel application of a spatiotemporal agent based model is presented which simulates two foraging species of different intrinsic growth rates competing for the same replenishing resource in stable and seasonal environments. This experimental approach provides precise control over the parameters for the environment, the species, and individual movements. Detailed trajectories of these non-equilibrium populations and their characteristics are produced. Narrow zones of potential coexistence are identified within the environmental and intrinsic growth parameter spaces. An example of commensalism driven by the local spatial dynamics is identified. Results of these experiments are discussed in context of modern coexistence theory and research in movement-mediated community assembly. Constraints on possible origination scenarios are identified.
