• Food, fishing and seabirds in the Benguela upwelling system (2007, background): “The decrease of penguins, which have a foraging range of up to about 40 km when breeding (Heath and Randall 1989; Petersen et al. 2006), preceded that of gannets, which are able to forage up to 240 km from colonies (Grémillet et al.”
• Novel GPS tracking of sea turtles as a tool for conservation management (2007, background): “The volume of data and degree of accuracy obtained using the TrackTagTM system are greatly improved in comparison to that obtained in previous GPS studies of marine wildlife (Sisak, 1998; Arai and Ono, 2002; Jay and Garner, 2002; Yasuda and Arai, 2005; Petersen et al., 2006), facilitating fine-scale”
• Central-Place Foraging in an Arctic Seabird Provides Evidence for Storer-Ashmole's Halo (2009, background): “Nonetheless, these correlations are not always observed (e.g., Falk et al. 2002, Frederiksen et al. 2005, Petersen et al. 2006) or are observed only in some years (Ainley et al. 2004).”
• Foraging distance affects reproductive success in Magellanic penguins (2009, background): “A positive relationship between trip distance and duration is known for several penguin species (e.g. Petersen et al. 2006, Boersma et al. 2007), but how that relationship varies is unknown.”
• Overlap between vulnerable top predators and fisheries in the Benguela upwelling system: implications for marine protected areas (2009, background): “Finally, both birds and fisheries overlap in the depth at which they exploit their prey, as gannets do not dive deeper than 30 m (Ropert-Coudert et al. 2004), and most penguin dives occur between 10 and 70 m (Wilson 1985, Petersen et al. 2006).”
• Collapse of South Africa's penguins in the early 21st century (2011, unknown): “Although African penguins are central-place foragers that feed near to colonies when breeding (Heath and Randall 1989, Petersen et al. 2006, Pichegru et al. 2010), in the non-breeding season they move considerable distances (Randall et al. 1987, Whittington et al. 2005a), so that their pre-breeding…”
