Imperceptible senescence: ageing in the ocean quahog Arctica islandica.
The ocean quahog Arctica islandica is the longest-lived of all bivalve and molluscan species on earth. Animals close to 400 years are common and reported maximum live span around Iceland is close to 400 years. High and stable antioxidant capacities are a possible strategy to slow senescence and extend lifespan and this study has investigated several antioxidant parameters and a mitochondrial ma...
متن کاملPhysiological responses to self-induced burrowing and metabolic rate depression in the ocean quahog Arctica islandica.
Arctica islandica is the longest-lived non-colonial animal found so far, and reaches individual ages of 150 years in the German Bight (GB) and more than 350 years around Iceland (IC). Frequent burrowing and physiological adjustments to low tissue oxygenation in the burrowed state are proposed to lower mitochondrial reactive oxygen species (ROS) formation. We investigated burrowing patterns and ...
متن کاملPhysiological aging in the Icelandic population of the ocean quahog Arctica islandica
The ocean quahog Arctica islandica is one of the longest-living and slowest growing marine bivalves. The oldest specimens obtained for the present study approached 200 yr. To achieve such a long lifespan, accumulation of oxidative damage markers in tissues must ideally be maintained at low levels over time, because the accumulating debris disturbs cellular functions. We investigated shell growt...

متن کاملA Metabolic Model for the Ocean Quahog Arctica Islandica—effects of Animal Mass and Age, Temperature, Salinity, and Geography on Respiration Rate
Owing to its extraordinary lifespan and wide geographical distribution along the continental margins of the North Atlantic Ocean, the ocean quahogArctica islandicamay become an important indicator species in environmental change research. To test for applicability and ‘‘calibrate’’ the Arctica-indicator, metabolic properties of A. islandica specimens were compared across different climatic and ...
