Intraspecific dietary variation in the short-beaked common dolphin Delphinus delphis in the Bay of Biscay: importance of fat fish (2008, background): “When modelling annual takes of resources by a population of marine mammals, the composition by mass of the diet is often considered to be constant over time and among the different segments of the population (e.g. Hammill & Stenson 2000, Bjørge et al. 2002).”
Quantifying the sensitivity of Arctic marine mammals to climate-induced habitat change. (2008, background): “When they first enter the water to feed, they prey on krill and other invertebrates until they improve their swimming and diving skills sufficiently to be able to capture fish (Hammill and Stenson 2000, Kovacs 2002a).”
Covariation between grey seal (Halichoerus grypus) abundance and natural mortality of cod (Gadus morhua) in the southern Gulf of St. Lawrence (2005, background): “Seals in Atlantic Canada have a varied diet and cod usually represent less than 20% of their diet (Hammill and Stenson 2000).”
Trophic role of Atlantic cod in the ecosystem (2009, background): “These and other mammals, such as minke whales, have not been adversely affected by the declines in cod populations, because cod is generally a small portion of their diet and they are sustained by other prey, most notably forage fish (Folkow et al. 2000; Hammill and Stenson 2000; Nilssen et al. 2000”
