• Evidence for impacts by jellyfish on North Sea herring recruitment (2005, background): “…of fish stocks could increase prey availability and release jellyfish from 162 Lynam et al.: Jellyfish impact on North Sea herring recruitment competitively imposed restrictions on population abundance, which may exacerbate any detrimental effect (Pauly et al. 1998, 2002, Sommer et al. 2002).”
• Enhancement of jellyfish (Aurelia aurita) populations by extensive aquaculture rafts in a coastal lagoon in Taiwan (2008, background): “Environmental conditions that seem to favour jellyfish have high nutrients, but low Si:N ratios, characteristic of eutrophic coastal waters (Sommer et al., 2002).”
• Quantifying carbon fluxes from primary production to mesopelagic fish using a simple food web model (2019, neutral): “In fact, this percentage is relatively high compared with estimates of fish catches of commercial fish species such as herring, plaice and sole, which are often between 0.05 and 0.1% of PP (Nielsen and Richardson, 1996; Sommer et al., 2002; Chassot et al., 2007, 2010).”
• Plankton in the open Mediterranean Sea: a review (2009, background): “…the key players, i.e., with a species-oriented approach; ii) their mutual interactions within the pelagic realm, with the aim of corroborating or improving existing descriptions of planktonic food web structure (Thingstad, 1998; Sommer et al., 2002) and highlighting the principal carbon producers.”
• Prey landscapes help identify potential foraging habitats for leatherback turtles in the NE Atlantic (2007, background): “Such shifts to gelatinous organism dominance in pelagic habitats have been speculated upon (Sommer et al. 2002) but are yet to be described.”
• Direct and indirect trophic interactions of Aurelia sp. (Scyphozoa) in a stratified marine environment (Mljet Lakes, Adriatic Sea) (2007, background): “The decline of fish competitors due to over-fishing has also been suggested as factor favouring jellyfish and contributing to regime shift (Daskalov 2002; Sommer et al. 2002).”
• Effects of low dissolved oxygen on planula settlement, polyp growth and asexual reproduction of Aurelia aurita (2008, background): “These will also help to elucidate how jellyfish could become dominant over fishes in regions affected by severe hypoxia, and how energy pathways are altered in these ecosystems (Breitburg et al. 1999, Sommer et al. 2002).”
• The trophodynamics of marine top predators: Current knowledge, recent advances and challenges (2015, background): “However, a common perception remains that gelatinous organisms represent a dead-end in marine food webs due to their low caloric value ( 0.1 KJ g 1 wet mass in Doyle et al., 2007; Sommer et al., 2002).”
• Predation on pelagic coelenterates: a review (2005, background): “A typical comment is that by Sommer et al. (2002); ‘Gelatinous zooplankton are usually considered a dead end in the pelagic food web because their low nutritional value makes them a minor food item for vertebrates, although there are some minor exceptions (e.g. the moon fish Mola mola and sea…”
• Efficiency of a phytoplankton‐based and a bacterial‐based food web in a pelagic marine system (2007, background): “Higher productivity may result in increased occurrence of inedible prey (Leibold 1989; Steiner 2001) and thereby decreased food web efficiency (Havens et al. 2000; Sommer et al. 2002).”
• Jellyfish fisheries in the Americas: origin, state of the art, and perspectives on new fishing grounds (2017, neutral): “Although jellyfish were often perceived to be trophic dead-ends (e.g., Verity and Smetacek 1996; Sommer et al. 2002), this perception is changing.”
