集合种群中的多尺度会产生矛盾的行为：在一个公共产品博弈的概念模型中，由于公共产品的生产，与适应度成本相关的物种可以稳定在良好混合的极限中，因为这些尺度的存在。在这个模型中的尺度涉及一个长度尺度对应于单独的补丁，耦合的流动性，和单独的时间尺度的繁殖和与当地环境的相互作用。相反，混合良好的高流动性限制，我们发现，对于低流动性，相互作用率逐步稳定这个物种由于随机效应，空间模式的形成是不是至关重要的这种稳定。
Multiple scales in metapopulations can give rise to paradoxical behavior: in a conceptual model for a public goods game, the species associated with a fitness cost due to the public good production can be stabilized in the well-mixed limit due to the mere existence of these scales. The scales in this model involve a length scale corresponding to separate patches, coupled by mobility, and separate time scales for reproduction and interaction with a local environment. Contrary to the well-mixed high mobility limit, we find that for low mobilities, the interaction rate progressively stabilizes this species due to stochastic effects, and that the formation of spatial patterns is not crucial for this stabilization.
