Última Etude ecophysiologique de quelques mollusques bivalves ArchiMer Riva, A; Masse, H. Using an experimental flowing system, the filtration rate of Mytilus galloprovincialis, Ostrea edulis, Ruditapes decussatus and Ruditapes aureus has been measured by an indirect technique under Mediterranean thermal conditions in coastal open sea. The oxygen consumption and excretion rate of ammonia have been estimated and influence of temperature and salinity tested for M. galloprovincialis . The results are discussed and compared to literature data.

Ano: 1983 URL: http://archimer.ifremer.fr/doc/1983/acte-1177.pdf Relations trophiques entre huitre et milieu; influence de la concentration et de la taille des particules ArchiMer Filia, M; Copello, M; Colomines, J. At 15 degree C, different concentrations of Phaeodactylum tricornutum are given to Crassostrea gigas . Ingestion, filtration, respiration, ammonia excretion have been measured. All ecophysiological response, except dissolved excretion, are dependent of food concentration. Energy balances have been determined and selectivity of particle size observed.

Ano: 1983 URL: http://archimer.ifremer.fr/doc/1983/acte-1178.pdf The economic cost of wetland destruction AgEcon Schmidt, Carmel Elizabeth. Wetlands are often refereed to as the ‘kidney of the river’, but what is the value of the water filtration they provide, and what is the cost of wetland destruction? This paper determines the economic value of wetlands for water filtration. It demonstrates that wetlands are of considerable economic value, even where the volume of water filtered is in excess of that required for domestic consumption. It argues that if legislation required those who destroy natural wetlands to replace the water filtration process the wetlands once provided, it would be necessary to construct water filtration plants at significant cost.
