• Impacts of climate change on marine organisms and ecosystems. (2009, background): “There is evidence for a steep decline in krill abundance from the 1970s [120], and this could have had adverse effects for the suite of higher predators that depend upon krill for food [121].”
• The fishery for Antarctic krill – recent developments (2012, background): “The most ambitious of these examinations, which used all available data from scientific nets, concluded that there had been a contraction in the range of krill to the South and that this had been associated with a significant decline in krill density (Atkinson et al. 2004).”

• Spatial association between hotspots of baleen whales and demographic patterns of Antarctic krill Euphausia superba suggests size-dependent predation (2010, positive): “Antarctic krill exhibit a circumpolar distribution in the Southern Ocean, with the largest concentrations located in the Southwest Atlantic (Atkinson et al. 2004), an oceanographically complex region characterized by the eastward flowing Antarctic Circumpolar Current (ACC) and bathymetrically…”
• Southern Ocean iron fertilization by baleen whales and Antarctic krill (2010, background): “There are suggestions that the current population of krill may be only 20% of its pre-1980s size (Atkinson et al. 2004).”

Predictive models based on food, temperature, body length, sex, and maturity stage (2006, background): “Over 50% of krill stocks are located in the southwest Atlantic sector (Atkinson et al. 2004), a region of rapid upper ocean warming (Meredith and King 2005), loss of winter sea ice (Parkinson 2002), and great interannual variability in chlorophyll a (Chl a) concentrations (Constable et al. 2003).”
• Distribution, Biomass and Demography of Antarctic Krill, Euphausia superba (2016, background): “The calculations indicated that 58–71% of krill are located within the Southwest Atlantic, a phenomenon that has been reported repeatedly (Siegel 2000; Nicol et al. 2000a; Constable et al. 2003; Atkinson et al. 2004).”
