Description: The unique size reduction and restitution cycle of diatoms requires special attention in modeling their population dynamics. Matrix models based on distinct size classes are generally necessary to fully address periodic changes in cell size distribution and understand infra-annual algae blooms. Here, different approaches for such size-resolved models are compared, with their conclusions about oscillatory behavior in diatom populations. Particularly, the coupling of model parameters with environmental signals that may act as zeitgebers are discussed.
