Analysis of annual fluctuations of C. nodosa in the Venice lagoon : Modeling approach

摘要: Abstract A simple simulation model was developed to describe the growth trends of Cymodocea nodosa (Ucria) Ascherson based on data sets from Venice lagoon. The reproduces seasonal fluctuations in above and belowground biomass shoot density. modeling results are good agreement with net production, rates chemical–physical parameters water. It assumed that light temperature most important factors controlling C. development, not limited by nutrient availability. aim simulate production as a function external forcing variables (light, water temperature) internal control (plant density). series experiments were performed basic showing among phenomena affecting are: (1) inhibition recruitment new shoots high (2) attenuation due fluctuation.
