- Trophic niche of squids: Insights from isotopic data in marine systems worldwide (2013, background): “For example, large species such as the colossal squid and the Humboldt squid, which had the greatest BA-dN values, act as top predators in some systems, preying on large fishes and other cephalopods (Cherel et al., 2008; Cheung and Pitcher, 2005; Cisneros-Montemayor, 2007; Hückstädt et al., 2007).”
- Assessing the life history of an andean traveller through biogeochemistry: Stable and radiogenic isotope analyses of archaeological human remains from Northern Chile (2012, background): “Similar trends in marine d15N(AIR) enrichment are also apparent in the central Chilean coast (Hückstädt et al., 2007).”
- Historic diet change of the South American sea lion in Patagonia as revealed by isotopic analysis (2009, background): “…sea lions off central Chile, for instance, have also been reported to have shifted recently to a more pelagic diet (Hückstädt & Antezana 2003, Hückstädt et al. 2007), due to the development of a purse-seine fishery targeting pelagic fish (Hückstädt & Antezana 2003) and increased…”
- A three-isotope approach to disentangling the diet of a generalist consumer: the yellow-legged gull in northwest Spain (2010, methodology): “Because IsoSource feasible solutions can be derived independently of the number of sources and isotopes, this model has been thoroughly applied to infer the feeding ecology of invertebrates (Laurand and Riera 2006), marine mammals (Hückstädt et al. 2007), birds (Inger et al.”
- Revisiting Peruvian anchovy (Engraulis ringens) trophodynamics provides a new vision of the Humboldt Current system (2008, methodology): “Finally, in Central Chile, using isotope analysis, Hückstädt et al. (2007) estimated the trophic level of anchoveta to 3.63, which confirm the dominance of zooplankton in anchoveta diet.”
