Modelling the photosynthetic efficiency for Ulva rigida growth

The performance of Eilers' model, in a modified version, was analysed with reference to the photosynthetic efficiency of the seaweed Ulva rigida growing in the Lagoon of Venice. The Eilers' formulation for the photosynthetic productivity, coupled with two functions presented in this application, represents a complete model calibrated on Ulva rigida, which for a given temperature and light intensity can give a reliable description of the photosynthetic behaviour of this seaweed. Further improvement is discussed, which includes the compensation point for light intensity in the model.
