Foraging behavior of lactating South American sea lions (Otaria flavescens) and spatial-temporal resource overlap with the Uruguayan fisheries (2013, background): “This may suggest, consistent with Costa’s model of foraging behavior modification (Costa, 2008), that lactating SASLs have a window to alter their foraging behavior (increase foraging time and push their diving limits) without changing the duration of their foraging trips to accommodate for changes ”
A bioenergetics model to evaluate demographic consequences of disturbance in marine mammals applied to gray whales (2015, methodology): “Bioenergetics models are used to understand life history requirements (Costa 2001, 2008, Molnar et al. 2009, Christiansen et al. 2013b, Fortune et al. 2013, Stephens et al. 2014) and quantitatively assess the effort animals spend acquiring resources, and how they allocate those resources.”
The population decline of the New Zealand sea lion Phocarctos hookeri: a review of possible causes (2011, background): “…composed of long-term individual foraging strategy specialists, such as female NZ sea lions, are thought to be highly susceptible to, and less able to respond to, environmental changes or anthropogenic impacts (Costa 1993, 2007, Gales & Mattlin 1997, Bolnick et al. 2003, Chilvers et al. 2006).”
Multiple foraging strategies in a marine apex predator, the Galapagos sea lion Zalophus wollebaeki (2008, background): “This creates a conflict between continuing to forage and returning to the rookery to suckle their pup (Costa 2008).”
Age, body mass and environmental variation shape the foraging ontogeny of Galapagos sea lions (2012, result): “Similar adjustments were found in other otariid species comparing years with higher and lower productivity (McCafferty et al. 1998, Georges et al. 2000, Costa 2008, Melin et al. 2008).”
Accelerometers can measure total and activity-specific energy expenditures in free-ranging marine mammals only if linked to time-activity budgets (2017, background): “However, the impact of these factors might be minimal if animals have high locomotion costs and operate close to their metabolic ceilings (Costa 2007).”
