(Mollusca): a reflection of hydrography-related food supply [Elektronische Daten] [Rob Witbaard] The growth lines in shells of Arctica islandica from the Fladen Ground have been used to construct long-term chronologies of growth variations. Individual specimens showed characteristic sequences of periods in high and low growth rates. Because the deviations were strongly synchronized, an environmental factor is held responsible. Inter-annual variations in either temperature or phytoplankton abundance could not explain the observed variations. The hypothesis is therefore put forward that the occurrence of dense patches of Arctica and the variations in growth result from variations in import and accumulation of organic matter by an eddy system overlying the area. Evidence for this hypothesis is provided by the correlation between the estimated inter-annual influx of Atlantic water into the North Sea and the observed growth variations. © 1996 International council for the Exploration of the Sea Articles nationallicence Arctica islandica nationallicence Fladen Ground nationallicence growth patterns nationallicence hydrography nationallicence ICES Journal of Marine Science Oxford University Press 53/6(1996-12), 981-987 1054-3139 53:6<981 1996 53 icesjms https://doi.org/10.1006/jmsc.1996.0122 text/html Onlinezugriff via DOI 1 research-article jats NATIONALLICENCE 856 40 https://doi.org/10.1006/jmsc.1996.0122 text/html Onlinezugriff via DOI NATIONALLICENCE 100 1- Witbaard Rob Netherlands Institute for Sea Research (NIOZ), PO Box 59, 1790 AB Den Burg, Texel, The Netherlands NATIONALLICENCE 773 0- ICES Journal of Marine Science Oxford University Press 53/6(1996-12), 981-987 1054-3139 53:6<981 1996 53 icesjms Metadata rights reserved CC BY-NC-4.0 http://creativecommons.org/licenses/by-nc/4.0 nationallicence BK010053 XK010053 XK010000 NATIONALLICENCE NATIONALLICENCE NL-oxford
