Antarctic silverfish: life strategies of a key species in the high-Antarctic ecosystem (2012, background): “In the presence of seasonal light, they exhibit diel vertical migration of as much as 350 m, moving to shallower depths at night and deeper during the day (Plötz et al. 2001; Fuiman et al. 2002; Robison 2003; Lancraft et al. 2004).”
Fine-scale three-dimensional spatial use by diving, lactating female Weddell seals Leptonychotes weddellii (2002, background): “Plotz et al. (2001) found that Weddell seals in the Weddell Sea in February did dive to the ocean floor, where they fed on adult Pleurogramma antarcticum which migrated to deeper depths during daytime.”
Regional, temporal and fine-scale spatial variation in Weddell seal diet at four coastal locations in east Antarctica (2003, background): “The diet in the Tryne area was characterised by the pelagic fish Pleuragramma antarcticum, which feed on krill, which in turn feed on algae that bloom in summer as the ice melts (Plötz et al. 2001).”
The role of fish in the Antarctic marine food web: differences between inshore and offshore waters in the southern Scotia Arc and west Antarctic Peninsula (2002, background): “However, deep dives on the bottom would not be the usual diving mode of Weddell seals, but continuous foraging on available midwater species (mainly P. antarcticum), with occasional shifts to benthic feeding (see Testa 1994, Plötz et al. 2001).”
Biotelemetry: a mechanistic approach to ecology. (2004, methodology): “For Weddell seals Leptonychotes weddellii, prey ingestion has also been measured by recording jaw opening [ 50 ] ,a nd even more directly by video recording with animal-borne cameras [51].”
The role of notothenioid fish in the food web of the Ross Sea shelf waters: a review (2004, background): “Most of these are small benthic or epibenthic fish (see Table 2), which may not be easily available to predators foraging in deep waters near the bottom, such as Weddell seals and emperor penguins (Kooyman and Kooyman 1995; Plötz et al. 2001).”
