• Natural growth rates in Antarctic krill (Euphausia superba): II. Predictive models based on food, temperature, body length, sex, and maturity stage (2006, background): “Their maximum ingestion rate is still debated (Clarke et al. 1988; cf. Pakhomov et al. 2002), but if we know their maximum growth rates, these can bound the estimates of ingestion.”
• Zooplankton biomass estimation from digitized images: a comparison between subtropical and Antarctic organisms (2009, background): “…of chaetognaths is estimated to be 10% to 30% of that of copepods in the world oceans (Bone et al. 1991), and the tunicate Salpa thompsoni is among the most important filter-feeding metazoans of the Southern Ocean, ranking only after copepods in terms of total biomass (see Pakhomov et al. 2002).”
• Defecation by Salpa thompsoni and its contribution to vertical flux in the Southern Ocean (2009, background): “The abundance and distribution of S. thompsoni has been measured in several studies (Foxton 1966; Huntley et al. 1989; Chiba et al. 1999; Pakhomov 2002; Atkinson et al. 2004) and in two cases population size and structure has been coupled with direct defecation measurements (Huntley et al. 1989; P”
• Marine pelagic ecosystems: the West Antarctic Peninsula (2007, background): “…in the Southern Ocean, the advance and retreat trends are weak except in the western Ross Sea region where winter sea ice duration is increasing (Parkinson 2002), concurrent with trends towards an earlier advance and later retreat (Stammerjohn et al. in press a), and overall increasing winter…”
• The role of grazing in structuring Southern Ocean pelagic ecosystems and biogeochemical cycles (2004, background): “Since salps are more abundant in HNLC areas than in the high productive regions favoured by krill (Pakhomov et al. 2002), the trend could be due to a decline in productivity in the SW Atlantic.”
• Phytoplankton spatial distribution patterns along the western Antarctic Peninsula (Southern Ocean) (2003, methodology): “The average filtration rate for each size category was calculated as described in Pakhomov et al. (2002), and the grazing impact due to salps for each station was calculated by multiplying the filtration rate for each size category by the proportion of that size category and the total number of…”
• Long-term decline in krill stock and increase in salps within the Southern Ocean (2004, background): “gif" NDATA ITEM> ]> Antarctic krill ( Euphausia superba ) and salps (mainly Salpa thompsoni ) are major grazers in the Southern Ocea”
• Carbon fluxes and pelagic ecosystem dynamics near two western Antarctic Peninsula Adélie penguin colonies: an inverse model approach (2013, methodology): “With around 40% of ingested nitrogen and 49% of ingested carbon excreted (Pakhomov et al. 2002), salps also increase the pool of dissolved organic matter available for bacterial production.”
• An overview of Southern Ocean zooplankton data: abundance, biomass, feeding and functional relationships (2012, background): “superba, and both groups have been assigned significant roles in vertical biogeochemical fluxes (Fortier et al., 1994; Dubischar and Bathmann, 1997; Pakhomov et al., 2002a; Schmidt et al., 2011; Atkinson et al., 2012).”
• Oceanic circumpolar habitats of Antarctic krill (2008, result): “2 shows much more even cir- cumpolar distributions for other zooplankters, a finding since supported by specific studies on copepods (Andrews 1966) and salps (Foxton 1966, Pakhomov et al. 2002, Atkinson et al. 2004).”
