Abstract

Theoretical approaches to describe population dynamics tend to focus on a particular scale, balancing the trade-offs of including each type of interaction. For small scales, individual-based models (IBM) can account for an arbitrary level of detail. However, due to its high computational cost, it is limited to small population sizes. For large scales, density-field descriptions (DFD) have been used, but they neglect the dynamics below a cut-off scale. To reconcile both approaches one can perform a coarse-graining procedure that patches together IBMs and DFDs. Since, in general, the emergent properties of the IBMs are out-of-equilibrium and regulated by a complicated set of forces, one should look for computational ways of linking both descriptions. In this talk, I will go through the multiscale framework that collaborators and I have developed to address the large-scale patterns produced by plankton communities.
