Microscale and related macroscale models of coexistence in Phalaris arundinacea, a globally distributed grass. Each color represents the spatial extent of a distinct genotype in a microscale model using stochastic cellular automata. Each curve on the graph represents the population level of a corresponding genotype in a macroscale differential equation model.
Microscale models form a broad class of computational models that simulate fine-scale details, in contrast with macroscale models, which amalgamate details into select categories. Microscale and macroscale models can be used together to understand different aspects of the same problem.
