Geographic variation in the foraging behaviour, diet and chick growth of rockhopper penguins (2003, methodology): “(3) During the brooding period, females make daily foraging trips, feeding at that time in the immediate vicinity of the colonies and spending the night ashore (Warham 1975, Cherel et al. 1999, Tremblay & Cherel 2000).”
Seabird foraging behaviour indicates prey type (2008, background): “Specifically, V-shaped dives are often thought to represent pelagic foraging (e.g. Tremblay & Cherel 2000).”
Regional, temporal and fine-scale spatial variation in Weddell seal diet at four coastal locations in east Antarctica (2003, background): “Hypothetically, the proportion of benthic to pelagic prey should increase in shallow water because benthic prey is more accessible (Tremblay & Cherel 2000).”
Amphipod-based food web: Themisto gaudichaudii caught in nets and by seabirds in Kerguelen waters, southern Indian Ocean (2001, background): “Both CDP and SRP are able to catch prey at depths (Bocher et al. 2000b, Tremblay & Cherel 2000), and they are commonly observed feeding in the vicinity of the colonies during the daylight hours (authors’ unpubl. data).”
Bottom or midwater: alternative foraging behaviours in adult female loggerhead sea turtles (2007, background): “In some species such as penguins, individuals use both benthic and pelagic foraging strategies (e.g. Tremblay & Cherel, 2000), whereas in other vertebrates such as otariids (sea lions and fur seals), the foraging strategies used differ by species (e.g. Costa & Gales, 2003).”
Spatial and temporal variation in the diet of the gentoo penguin (Pygoscelis papua) at Kerguelen Islands (2004, unknown): “…and Eudyptes chrysolophus, e.g. Cherel and Ridoux 1992; Bost et al. 1997; Green et al. 1998) to inshore benthic feeders like gentoo, rockhopper and chinstrap penguins (Pygoscelis papua, E. chrysocome and P. antarctica, e.g. Williams et al. 1992; Wilson and Peters 1999; Tremblay and Cherel 2000).”
Complete trophic segregation between South Georgian and common diving petrels during breeding at Iles Kerguelen (2000, unknown): “…the small and overwhelming herbivorous endemic copepod Drepanopus pectinatus, Euphausia vallentini, and the carnivorous Themisto gaudichaudii and Paraeuchaeta antarctica, Calanus simillimus being less numerous (Bost et al. 1994, Razouls et al. 1996, Tremblay & Cherel 2000, author’s unpubl. data).”
Multiple foraging strategies in a marine apex predator, the Galapagos sea lion Zalophus wollebaeki (2008, background): “The deep divers presented characteristically deep dives, and had the lowest percentage of consecutive dives to the same IDZ, indicating that they were not likely feeding on the benthos.”
A comparison of indirect measures of feeding behaviour based on ARGOS tracking data (2007, background): “On deep dives, transit time will necessarily reduce available bottom time; therefore, a bottom time of a particular duration will have a different biological interpretation at different depths (Tremblay and Cherel, 2000).”
Comparison of diving behavior and foraging habitat use between chinstrap and gentoo penguins breeding in the South Shetland Islands, Antarctica (2010, background): “In addition, because the maximum depth of a dive has a significant effect on dive duration, diving bottom duration, descent and ascent speeds, the analysis of these factors included the effect of dive depth as a covariate ( Tremblay and Cherel 2000 ).”
Diving seabirds share foraging space and time within and among species (2010, methodology): “However, wiggles have been found to be associated with feeding behavior in several penguin species (number of beak openings: Takahashi et al. 2004, ingestion rate: Bost et al. 2007), and have been used as a measure of feeding activity in Rockhopper Peguins (Tremblay and Cherel 2000).”
Foraging under contrasting oceanographic conditions: the gentoo penguin at Kerguelen Archipelago (2005, methodology): “%) on pelagic crustaceans trapped on the sea floor (Tremblay & Cherel 2000).”
Foraging strategies and prey encounter rate of free-ranging Little Penguins (2006, background): “Benthic or demersal feeding has already been noted in emperor Aptenodytes forsteri (Rodary et al. 2000), chinstrap Pygoscelis antarctica (Takahashi et al. 2003), gentoo P. papua (Croxall et al. 1988; Wilson et al. 1991; Robinson and Hindell 1996), rockhopper Eudyptes chrysocome ( Tremblay and Cherel”
Individual dietary specialization and dive behaviour in the California sea otter: Using archival time–depth data to detect alternative foraging strategies (2007, background): “…now been detected in a variety of species including Antarctic fur seals (Lea et al., 2002b; Staniland et al., 2004), grey seals (Austin et al., 2004), narwhals (Laidre et al., 2003), cormorants (Kato et al., 2000), and several species of penguins (Radl and Culik, 1999; Tremblay and Cherel, 2000).”
