• Effect of zooplankton‐mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates) (2009, background): “Marine studies have focused mainly on the copepod–ciliate link (Levinsen et al. 2000; Broglio et al. 2004; Calbet and Saiz 2005); only a few field investigations have examined whether predation effects on microzooplankton are transferred to heterotrophic nano- and picoplankton (Sipura et 1…”
• Top-down” regulation in ctenophore – copepod – ciliate – diatom - phytoflagellate communities in coastal waters: a mesocosm study (2002, background): “Other studies on the importance of ciliates as a food source for copepods have been reviewed by Turner & Roff (1993) and Levinsen et al. (2000), and references therein.”
• Zooplankton grazing on Phaeocystis: a quantitative review and future challenges (2007, result): “occurs. These results were also supported by Levinsen et al. (2000) , who reported ingestion of single P. pouchetii by the smaller females of C. Wnmarchus but not by the larger C. glacialis and C. hyperboreus.”
• Molecular detection of algal prey in copepod guts and fecal pellets (2003, background): “Because nonpigmented ciliates and heterotrophic dinoflagellates are generally available, and even preferred, as prey by copepods (Stoecker and Capuzzo 1990; Kleppel 1993; Fessenden and Cowles 1994; Suzuki et al. 1999; Levinsen et al. 2000; Nejstgaard et al. 2001), the ability to directly investigate”
• Lipids and life strategy of Arctic Calanus (2009, background): “It is well known that Calanus has a flexible feeding strategy and is able to switch to alternative prey when fresh phytoplankton are scarce, including nauplii (Bonnet et al. 2004; Basedow & Tande 2006) and protozooplankton (Mauchline 1998; Levinsen et al. 2000).”
• Seasonal and interannual phytoplankton production in a sub-Arctic tidewater outlet glacier fjord, SW Greenland (2015, background): “…& Macdonald 2004, Tremblay et al. 2006, 2008), species composition (Grøntved & Seidenfaden 1938, Poulsen & Reuss 2002, Coello-Camba et al. 2014) and grazing pressure during the productive season (Levinsen et al. 2000, Madsen et al. 2008, Arendt et al. 2010, Calbet et al. 2011, Tang et al. 2011).”
• Heterotrophic dinoflagellates: a significant component of microzooplankton biomass and major grazers of diatoms in the sea (2007, background): “…serve as a quantitatively and qualitatively significant food resource for mesozooplankton (Stoecker & Capuzzo 1990, Kleppel 1993, Suzuki et al. 1999, Levinsen et al. 2000, Vincent & Hartmann 2001, Leising et al. 2005b,c, Liu et al. 2005, Olson et al. 2006, Campbell et al. in press).”
• Plankton community structure and carbon cycling in a coastal upwelling system. I: Bacteria, microprotozoans and phytoplankton in the diet of copepods and appendicularians (2004, background): “Similarly, Levinsen et al. (2000) observed that Calanus spp. generally grazed ciliates more efficiently than phytoplankton, and Frost (1972) also found an increase in clearance by C. pacificus with increasing size of diatoms up to the largest species examined (~67 µm ESD).”
• Biomass, production and horizontal patchiness of sea ice algae in a high-Arctic fjord (Young Sound, NE Greenland) (2001, background): “Furthermore, the low algal biomass does not seem to be caused by high grazing pressure, since the biomass of grazers was not exceptionally high in Young Sound but comparable to other locations (Rysgaard et al. 1999, Levinsen et al. 2000).”
• Timing of reproductive events in the marine copepod Calanus glacialis: a pan-Arctic perspective (2013, background): “Calanus glacialis is not strictly herbivorous (Ohman and Runge 1994; Levinsen et al. 2000 b ; Campbell et al. 2009), but it feeds mainly on microalgae during the spring bloom (Runge & Ingram 1988; Tourangeau and Runge 1991; Juul-Pedersen et al. 2006) and is also able to exploit ice algae at the…”
