In the Lagoon of Lesina, the autotrophic phytoplankton biomass
depends not so much on the nutrient load as on the remineralisation
of organic matter (for which the necessary vector may be
suspended particulate matter), the limitation of phosphorus and
the presence of macrophytes distributed throughout the basin
which compete effectively for nutrients. Consequently, the complex
relationships between the variables and the forcing factors
constitute an important component of the system, able to modulate
effects arising from the input of organic matter and nutrients and
the resulting internal dynamics, and to influence its dynamic
equilibrium
