Trophic position of Antarctic amphipods — enhanced analysis by a 2-dimensional biomarker assay (2005, background): “Only a few stable isotopic studies have been focussed on benthic communities so far (Dunton 2001, Nyssen et al. 2002).”
Trophic relationships in the nearshore zone of Martel Inlet (King George Island, Antarctica): δ13C stable-isotope analysis (2003, background): “In the nearby shelf areas of the King George Basin most of the brown macroalgae show a carbon isotope ratio around )20& (Fisher 1991; Fisher and Wiencke 1992) and in the Anvers Island coastal zone the isotopic ratio for Desmarestia menziesii and D. anceps was )25& (Dunton 2001).”
Trophic importance of kelp-derived suspended particulate matter in a through-flow sub-Antarctic system (2006, background): “…particulate matter · SPM · Tropic subsidy · Sub-Antarctic · Stable isotopes Resale or republication not permitted without written consent of the publisher Mar Ecol Prog Ser 316: 17–22, 2006 assimilated by consumers spanning several trophic levels (Kaehler et al. 2000, Dunton 2001, Fredriksen 2003).”
Trophic importance of Laminaria hyperborea to kelp forest consumers and the importance of bacterial degradation to food quality (2003, background): “The 15N:14N isotope data indicate that the species investigated have a low trophic position in the food web (cf. Dunton 2001).”
High trophic overlap within the seabird community of Argentinean Patagonia: a multiscale approach (2004, result): “4a) similar to those in both northern (Hobson & Welch 1992; Sydeman et al. 1997) and southern oceans (Wada et al. 1987; Rau et al. 1992; Dunton 2001).”
Life strategy, ecophysiology and ecology of seaweeds in polar waters (2007, background): “…water systems is low but several organisms depend fully or in part on seaweeds as a food source in the Antarctic (Brand 1974; Richardson 1977; Iken et al. 1997, 1999; Iken 1999; Dunton 2001; Graeve et al. 2001) and the Arctic (Lippert et al. 2001; Wessels et al. 2006; Dunton and Schell 1987).”
Macroalgal detritus and food-web subsidies along an Arctic fjord depth-gradient (2015, background): “Macroalgae in both Arctic and Antarctic systems are predicted to increase with warming temperatures and reduced sea-ice cover (Krause-Jensen et al., 2012; Clark et al., 2013) and this may already be occurring in some areas (Węsławski et al., 2011; Kortsch et al., 2012).”
Food Web Structure of the Alaskan Nearshore Shelf and Estuarine Lagoons of the Beaufort Sea (2012, methodology): “For example, in the Antarctic Peninsula, Dunton (2001) used a value of 3.2‰ per trophic level, which is comparable to values of 3.3‰ applied by Wada et al. (1987) to the Southern Ocean and Rau et al. (1992) in the northeast Atlantic.”
