论文摘要
当人均生长速率在低密度下增加时，就会发生合同效应。在这里，我们调查了部分移民人口的进化稳定性，其移民人口经历了质量影响。部分迁移是表型多样性的一种独特形式，其中移民和非移民个体共存。结果表明，当纳入效应时，人口会进行分叉，因为迁移人口的比例从零增加到统一。使用进化游戏理论方法，我们证明了独特的进化稳定策略（ESS）的存在。还表明，在部分迁移的人群的背景下，ESS是唯一的理想自由分布（IFD）。
An Allee effect occurs when the per-capita growth rate increases at low densities. Here, we investigate the evolutionary stability of a partial migration population with migrant population experiencing Allee effects. Partial migration is a unique form of phenotypic diversity wherein migrant and non-migrant individuals coexist together. It is shown that when Allee effect is incorporated, the population undergoes a bifurcation as the fraction of migrating population increases from zero to unity. Using an evolutionary game theoretic approach, we prove the existence of a unique evolutionary stable strategy (ESS). It is also shown that the ESS is the only ideal free distribution (IFD) that arises in the context of partially migrating population.
