问题:在离散时间元种群模型中,Allee效应能否通过扩散进化促进进化自杀?数学方法:自适应动力学。模型特征:由无限多个斑块组成的元种群。在离散时间定义的局部动力学、扩散和突变事件。结果:基于适应度的计算表明,进化自杀可能发生在模型中。进化模拟支持这一结果。在进化分支之后,二态进化自杀不会发生。
Question: Can the Allee effect promote evolutionary suicide by dispersal evolution in a discrete-time metapopulation model? Mathematical methods: Adaptive dynamics. Features of model: Metapopulation consisting of infinitely many patches. Local dynamics, dispersal, and catastrophe events defined in discrete time. Results: Fitness-based calculations show that evolutionary suicide can happen in the model. Evolutionary simulations support the result. After evolutionary branching, dimorphic evolutionary suicide does not occur.
