VERBI VEnice Research BIbliography

The biomass, the morphometric variation and the net production of the seagrass Nanozostera noltii (Hornemman) Tomlinson et Posluzny, were studied bimonthly, from January to December 2005, in two stations (Lido watershed, in the central basin and Petta di Bò in the southern basin) of the Venice lagoon.
Concurrently, the main environmental variables and nutrient concentrations were also recorded. The selected stations allowed to study the growth of that species in a natural environment (Petta di Bò) and in an area affected by anthropic interventions with inputs of sandy sediments (Lido watershed) where it had been transplanted. The results obtained in the two stations allowed to understand the growth strategy of that species and to calculate the total lagoon net production by the P/B ratio, obtained during one year sampling, and its distribution in the lagoon according to a biomass map drawn in summer 2003.
The plant biomass, the metrics and the main environmental variables linked to the growth of that species obtained at Petta di Bò were also compared with those obtained in the same station in 1994.
