• Movements of satellite-monitored humpback whales on their feeding ground along the Antarctic Peninsula (2008, unknown): “Satellite telemetry has been successfully used to investigate behavior (e.g., Laidre et al. 2003), associations with environmental features (e.g., Baumgartner and Mate 2005; Etnoyer et al. 2006), habitat use, migration and movement patterns (e.g., Mate et al. 1998, 1999; Heide-Jørgensen et al.…”
• A novel method for identifying behavioural changes in animal movement data. (2009, background): “Many fundamental demographic parameters can be directly related to animal movements, including foraging success, breeding success, migration and dispersal (Guinet et al. 2001; Mauritzen et al. 2001; Laidre et al. 2003; Matthiopoulos 2003; Buskirk & Millspaugh 2006).”
• The migratory behaviour of narwhals (Monodon monoceros) (2003, background): “Narwhals occur in large densities on the wintering grounds (Koski and Davis 1994; Heide-Jørgensen et al. 2002a), but little is known about their feeding habits in these areas, although they are likely feeding close to the bottom on Greenland halibut (Laidre et al. 2003).”
• Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “The prevalence of ringed seals decreased dramatically with a shift to a warmer climate beginning in the 1920s (Rosendal 1961, Teilmann and Kapel 1998), while Arctic cod and other ringed seal prey items receded northward and Atlantic cod from Iceland invaded the West Greenland coast (Jensen 1939).”
• 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).”
• WINTER FEEDING INTENSITY OF NARWHALS (MONODON MONOCEROS) (2005, background): “During this period, they exhibit frequent deep-diving behavior, making many dives to the bottom each day (depths .1,500 m) (Laidre et al. 2003).”
