| Title | The influence of environmental variables on Ulva rigida C Ag growth and production |
| Abstract | During the last few decades the increase of nutrient load, in addition to the reduced water exchange, has caused an abnormal increase of Ulva growth in the Lagoon of Venice. In order to assess the influence of environmental variables (light, temperature and nutrient concentrations) on Ulva growth and production, experiments in controlled and semi-natural conditions were carried out. |

In order to assess the influence of environmental variables light, temperature and nutrient concentrations on Ulva growth and production, experiments in controlled and semi natural conditions were carried out. Net production, growth and nutrient uptake rates increased with temperature from 10 to 20 degrees C while they showed a slight reduction at 30 degrees C. The net production rate increased with light intensity up to about 475 mu mol s 1 m 2 and then decreased at higher illumination values. Net production occurred even in very low light 1.9 mu mol s 1 m 2 and only a slight inhibition of photosynthesis was caused by light intensities as high as 2280 mu mol s 1 m 2 Moreover, the photosynthetic capacity was not severely damaged by dark exposure for a relatively long time. 39 Published version Articolo in rivista de Gruyter. 0006 8055 Botanica marina Print Botanica marina Print Bot. mar.
