Abstract

Many amphibian larvae navigate a balance between resource consumption and metamorphosis to escape dwindling ponds. This complex process, influenced by environmental, physiological, and genetic factors, has been difficult to model. We have created an agent-based model, built on Ambystoma maculatum data, encapsulating the complex life cycle dynamics of amphibians. Our approach integrates four developmental stages (egg, larva, juvenile, adult) with parameters reflecting real-life organismal attributes, including genes affecting metamorphic risk. The model features configurable environmental patches with mortality risk, habitat permeability, and food availability parameters. Its versatility accommodates various amphibian species and heterogeneous environments, supporting diverse use cases. We have tested the model to investigate gene flow and natural selection across spatial scenarios. Initial testing indicates that the model can produce unique population genetic structures under different parameterizations. The model has the potential to serve as a powerful tool for conservation efforts, population genetics research, and education.
