Abstract
In this paper, we build up an individual -based model (IBM) that
describes the aggregative behavior in phytoplankton. The processes in
play at the individual level (an individual = a phytoplankton cell) are:
a random dispersal, a displacement due to the net effect of cells
present in a suitable neighborhood (spatial interactions) and a
branching (cell division and death). The IBM model provides a virtual
world where phytoplankton cells appear to form clusters. Using this
model, we explore the spatial structure of phytoplankton and present
some numerical simulations that help the understanding of the
aggregation phenomenon.
