• Feeding ecology of deep-sea seastars (Echinodermata: Asteroidea): a fatty-acid biomarker approach (2003, background): “Stable isotope analysis of D. grandis grandis has also found it to feed extensively on benthic deposit feeders (Iken et al. 2001).”
• Benthic foraminifera as trophic links between phytodetritus and benthic metazoans: carbon and nitrogen isotopic evidence (2008, neutral): “As far as we know the only study applying this method to benthic foraminifera is Iken et al. (2001).”
• Food web structure in the high Arctic Canada Basin: evidence from δ13C and δ15N analysis (2005, neutral): “, holothurians and ophiuroids, at PAP are an indicator of the tight coupling to the primary production as these taxa effectively exploit fresh phytodetritus and thus remove a large part of the labile portion of annual deposition before it can be used by subsurface deposit feeders (Iken et al. 2001).”
• Trophic relationships in a deep Mediterranean cold-water coral bank (Santa Maria di Leuca, Ionian Sea) (2009, background): “…a time corresponding to the turnover of the tissue (e.g. several weeks or months for muscle), and is particularly useful for less accessible areas such as deep-sea benthic ecosystems as only a small amount of material is required for stable isotope analysis (Iken et al. 2001, Becker et al. 2009).”
• Spatial and temporal variations in deep-sea meiofauna assemblages in the Marginal Ice Zone of the Arctic Ocean (2007, background): “They rather respond when demineralization is already at an advanced stage, as shown by earlier evidence from stable isotope analyses at the Porcupine Abyssal Plain (Iken et al., 2001).”
• Stable C and N isotopic composition of cold-water corals from the Newfoundland and Labrador continental slope: Examination of trophic, depth and spatial effects (2008, background): “Deep-Sea Research I 55 (2008) 1392– 1402 Suspension feeding cnidarians at the Porcupine Abyssal Plain occupy a wide trophic niche, feeding on resuspended material and swimmers to compensate for seasonal shortages in fresh phytodetritus (Iken et al., 2001).”
• Extreme food webs: Foraging strategies and diets of scavenging amphipods from the ocean’s deepest 5 kilometers (2007, background): “Consequently, we expect that competition among scavengers for both food and space is likely to be severe (Iken et al. 2001).”
• ANTHROPOGENIC ENRICHMENT ALTERS A MARINE BENTHIC FOOD WEB (2005, background): “…et al. 2003) The importance of including allochthonous inputs (e.g., nutrients, carbon) into food-web dynamics has been highlighted in a number of recent papers (Polis and Strong 1996, Polis et al. 1997, 2004, Huxel and McCann 1998, Jefferies 2000, Iken et al. 2001, Moore et al. 2004).”
• Trophic structure and food resources of epipelagic and mesopelagic fishes in the North Pacific Subtropical Gyre ecosystem inferred from nitrogen isotopic compositions (2015, background): “Interestingly, slope-based demersal food web studies from the Atlantic and Antarctic have also used bulk stable isotopes to examine the variability of food resources with depth (Iken et al. 2001; Mintenbeck et al. 2007; Trueman et al. 2014).”
• Bypassing the abyssal benthic food web: Macrourid diet in the eastern North Pacific inferred from stomach content and stable isotopes analyses (2008, background): “armatus, had d15N values indicative of a TL lower than many benthic invertebrates such as polychaetes, asteroids, and hexactinellid sponges (Iken et al. 2001).”
• Diversity of the arctic deep-sea benthos (2011, background): “The ability of many elasipodids to take advantage of sedimentation events, and their fine trophic niche partitioning (Roberts et al. 2000; Iken et al. 2001), apparently contribute to the success of this group.”
