Growth of Isognomon alatus (Flat Tree Oyster) in acidified waters

Производитель: "LAP Lambert Academic Publishing"

The Flat Tress oyster, Isognomon alatus (Gmelin, 1791) is a sessile intertidal bivalve of coastal ecosystem. There is great concern over future effect of ocean acidification (high carbon dioxide concentration, lowering of ocean pH) on calcifying marine organisms (e. g. oysters). We examined how the ocean s present and projected lowering of pH will impact on the growth of Isognomon alatus. Isognomon alatus cultured under laboratory controlled projected 21st century pH levels ( 7. 8) demonstrated thinning of shell, decrease in weight and negative growth rates ( 0. 56 + 0. 36 mg g-1day-1). In contrast, I. alatus cultured within coastal waters of Mangrove Bay Estuary, Bermuda, under a ambient pH gradient ( 8. 1) displayed weight gain and positive growth (0. 26 + 0. 23 mg g-1day-1) although exposure to lower pH levels ( 7. 4) during low tide. The results indicate the sensitivity of oysters to acidified waters. The book provides understanding on the survival of oysters in acidified coastal waters... ISBN:9783659589867
