Imperceptible senescence: ageing in the ocean quahog Arctica islandicaDoris Abele
Department of Marine Bioscience, Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany
Free Radic Res 42:474-80. 2008..These findings support the 'Free Radical-Rate of Living theory', antioxidant capacities of A. islandica are extraordinarily high and thus may explain the species long life span...

Comp Biochem Physiol A Mol Integr Physiol 143:494-503. 2006..Notably the non-enzymatic antioxidant defense (e.g. glutathione) may play an important role for eelpout ROS scavenging capacity under cold stress...
Size- and age-dependent changes in adductor muscle swimming physiology of the scallop Aequipecten opercularisEva E R Philipp
Alfred Wegener Institute for Polar and Marine Research, Department of Biosciences, 27570 Bremerhaven, Germany
J Exp Biol 211:2492-501. 2008....
Heat-shock response and antioxidant defense during air exposure in Patagonian shallow-water limpets from different climatic habitatsKevin Pöhlmann
Alfred Wegener Institute for Polar and Marine Research, Bremerhaven, Germany
Cell Stress Chaperones 16:621-32. 2011..Close to the warm border of their distribution range, energy expenses to cope with stress might become overwhelming and represent one cause why the limpets are unable to colonize the shallow intertidal zone...
Differences in heavy metal concentrations and in the response of the antioxidant system to hypoxia and air exposure in the Antarctic limpet Nacella concinnaEllen Weihe
Alfred Wegener Institut fur Polar und Meeresforschung, Dept Functional Ecology, Am Handelshafen 12, 27570 Bremerhaven, Germany
Mar Environ Res 69:127-35. 2010..Intertidal limpets obviously avoid early onset of anaerobic energy production seen in their sub-littoral congeners when exposed to air and are still able to maintain tissue redox ratio balance when exposed to air...
Sex-specific biochemical and histological differences in gonads of sea urchins (Psammechinus miliaris) and their response to phenanthrene exposureSabine Schäfer
Alfred Wegener Institute for Polar and Marine Research within the Helmholtz Association, Am Handelshafen 12, 27570 Bremerhaven, Germany
Mar Environ Res 71:70-8. 2011..This study illustrates the difficulties to identify toxic injury in reproductive tissue as it may be superimposed by gametogenesis and spawning of gametes...
Metabolic and physiological responses in tissues of the long-lived bivalve Arctica islandica to oxygen deficiencyJulia Strahl
Alfred Wegner Institute for Polar and Marine Research, Bremerhaven, Germany
Comp Biochem Physiol A Mol Integr Physiol 158:513-9. 2011..3 in hemocytes. These differences in anaerobic enzyme activity patterns indicate that LDH and ODH play specific roles in different tissues of A. islandica which are likely to economize metabolism during anoxia and reoxygenation...
Oxidative stress during stressful heat exposure and recovery in the North Sea eelpout Zoarces viviparus LKatja Heise
Alfred-Wegener Institute for Polar and Marine Research, Physiology of Marine Animals, Am Handelshafen 12, 27570 Bremerhaven, Germany
J Exp Biol 209:353-63. 2006..We suppose that the more oxidized redox state during extreme heat may interfere with the hypoxic signaling response...
Seasonality of energetic functioning and production of reactive oxygen species by lugworm (Arenicola marina) mitochondria exposed to acute temperature changesMartina Keller
Alfred Wegener Institute for Polar and Marine Research, Columbusstrasse 27568 Bremerhaven, Germany
J Exp Biol 207:2529-38. 2004..In winter, low and less changeable temperatures in intertidal sedimentary environments permit higher respiratory efficiency at low aerobic metabolic rates and lower membrane potentials in A. marina mitochondria...

Centro Austral de Investigaciones Científicas CADIC CONICET c c 92 9410 Ushuaia, Tierra del Fuego, Argentina
Comp Biochem Physiol A Mol Integr Physiol 146:551-8. 2007..Together, the data indicate that both oxygen and nitrogen radical generation rates in N. (P.) magellanica are strongly dependent on season...
Chronological and physiological ageing in a polar and a temperate mud clamEva Philipp
, Okophysiologie, Postfach 120161, D-27568 Bremerhaven, Germany
Mech Ageing Dev 126:598-609. 2005..arenaria. Our results indicate that metabolic rates and maintenance of tissue redox state are major factors determining maximum lifespan in the investigated mud clams...

Comp Biochem Physiol B Biochem Mol Biol 132:729-37. 2002..L. elliptica had a higher content of alpha-tocopherol and beta-carotene than M. arenaria. Our data suggest that increased lipid radical content in the membranes of cold-adapted organisms could be related to iron content...
