Macroalgae, nutrient cycles, and pollutants in the Lagoon of Venice

  title={Macroalgae, nutrient cycles, and pollutants in the Lagoon of Venice},
  author={Adriano Sfriso and Bruno Pavoni and Antonio Marcomini and Angelo A. Orio},
The Lagoon of Venice is a wide, shallow coastal basin that extends for about 50 km along the northwest coast of the Adriatic Sea. The lagoon has been substantially modified through the actions of man over the last century through the artificial control of the hydraulic dynamics of the laggon including the construction of channels to facilitate navigation. The lagoon is subjected to considerable pollutant loading through the drainage of land under cultivation, municipal sewage, and industrial… 
Relationships between nutrients and macroalgal biomass in a brazilian coastal lagoon: the impact of a lock construction
The Piratininga Lagoon is a coastal, choked, and brackish ecosystem in SE Brazil, where uncontrolled discharge of domestic sewage led to eutrophication, increasing massive proliferation of benthic
Macroalgal blooms in coastal lagoons of the Gulf of California eco-region: a summary of current knowledge
Abstract The Gulf of California is an important eco-region with 52 coastal lagoons that are affected by the different anthropogenic activities in their surrounding areas. Several studies in the
Macroalgae and phytoplankton competition in the central Venice lagoon
Abstract The presence‐absence of macroalgae and/or phytoplankton in some areas of the Venice lagoon and the factors controlling the prevailing of one over the other were tested by monitoring two
Macroalgae Mediation of Dissolved Organic Nitrogen Fluxes in a Temperate Coastal Lagoon
The activity of the benthos, including benthic plants, is important in driving the overall system dynamics in shallow lagoons, due to the high ratio of sediment surface area relative to water volume.
Macroalgal biomass and species variations in the Lagoon of Venice (Northern Adriatic Sea, Italy): 1981-1998
SUMMARY: Over the past hundred years, the composition of the submerged aquatic vegetation of the Lagoon of Venice has changed considerably, due to increased anthropic activities and large-scale
Anthropogenic and natural effects on the water and sediments qualities of costal lagoons: case of the Boughrara Lagoon (Southeast Tunisia)
The Boughrara Lagoon located in southern Tunisia shows evidence of eutrophication and the deterioration of water quality. The large amount of water shown to exchange tidally between the lagoon and
Macroalgal Population and Sustainability
Abstract Algal blooms, often associated with eutrophication, are common in temperate regions in coastal lagoons and estuarine areas as well as in open seas. However, because of recent changes in
Restoration of the eutrophic Orbetello lagoon (Tyrrhenian Sea, Italy): water quality management.


Flora and vertical distribution of macroalgae in the lagoon of Venice: a comparison with previous studies
Many oligotrophic species, such as those belonging to the «Cystoseira association» have disappeared, whereas some genera, once very abundant, are presently strongly reduced, for instance Laurencia, Polysiphonia and Dasya.
The Production of Zostera marina L. and Other Submerged Macrophytes in a Coastal Lagoon in Rhode Island, U.S.A.
Year-round (1979-1980) biomass measurements of major species of submerged angiosperms and algae in Ninigret Pond, Rhode Island were used to calculate production äs g dry wt m". The annual production
Sampling strategies for measuring macroalgal biomass in the shallow waters of the Venice lagoon.
Abstract A number of procedures were tested to set up a reliable method for determining macroalgal standing crops in the shallow waters of the Venice Lagoon, populated by macroalgae with different
Relation Between Nitrogen and Phosphorus Content of Macroalgae and the Waters of Northern Öresund
The seasonal fluctuations in the nitrogen and phosphorus Content of 7 macrobenthic species or groups of species from Kullen, South Sweden were investigated and significant differences between the means of Phaeophyta and Rhodophyta were found.
Rates of nitrification, distribution of nitrifying bacteria, and nitrate fluxes in different types of sediment from Danish waters
These calculated rates agree with the actual measured rates of nitrification for a wide range of sediment types and may be used for the estimation of actual nitrification rates, by adjusting to in situ temperature and oxygen penetration.
