CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishHypoxia and anoxia are stress conditions that may affect physiological and biochemical responses in infaunal marine organisms, such as bivalves. Depending on the species, bivalves generally show a variable tolerance (measured as anoxic survival response) to hypoxia/anoxia periods, according to ability of organisms to modulate their metabolism. Low oxygen conditions have also been shown to affect bivalve immune responses (Hawkins et al., 1993; Pampanin et al., 2002). In this work, the effects of anoxia on functional responses of haemocytes were investigated in the commercially important species, Chamelea gallina. The capability of clams to recover after anoxic stress was also evaluated. Total haemocytes count (THC), phagocytosis and lysozyme activity were chosen as cellular biomarkers of exposure to anoxic conditions

| Abstract: | Hypoxia and anoxia are stress conditions that may affect physiological and biochemical responses in infaunal marine organisms, such as bivalves. Depending on the species, bivalves generally show a variable tolerance (measured as anoxic survival response) to hypoxia/anoxia periods, according to ability of organisms to modulate their metabolism. Low oxygen conditions have also been shown to affect bivalve immune responses (Hawkins et al., 1993; Pampanin et al., 2002). In this work, the effects of anoxia on functional responses of haemocytes were investigated in the commercially important species, Chamelea gallina. The capability of clams to recover after anoxic stress was also evaluated.
