Eco-evolutionary metapopulation dynamics of Batesian mimicry: Conditions for mimics without models

Batesian mimicry is adopted by palatable prey species (mimics) to avoid predator attack by resembling unpalatable species (models). Despite numerous studies on this phenomenon, several aspects of its evolution remain unclear. One of the most interesting questions is whether mimics can inhabit allopatrically from their models. Classical theory suggests that mimics should only inhabit sympatrically with their models because predators need to learn the model phenotype. However, several studies have reported mimics that live outside the distribution range of their models (mimics without models; MWM). In this study, we constructed and analyzed an eco-evolutionary dynamics model of Batesian mimicry incorporating two populations under different environmental conditions to clarify the conditions necessary for MWM to occur. We identified that MWM occurred when specific conditions are satisfied by the following six parameters: (1) carrying capacities; (2) migration rate of mimics; (3) migration r..., , , # Data from: Eco-evolutionary metapopulation dynamics of Batesian mimicry: Conditions for mimics without models
