Mass-dependent energetics and survival in Harbour Seal pups (2005, unknown): “The weight at weaning is significantly correlated with first year survival in for example: Southern Elephant Seals ( Mirounga leonina ) ( McMahon, Burton & Bester 2000 ), Northern Fur Seals ( Callorhinus ursinus ) (Baker & Fowler 1992) and Grey Seals ( Halichoerus grypus ) (Hall, McConnell & Barker ”
Population status, trends and a re-examination of the hypotheses explaining the recent declines of the southern elephant seal Mirounga leonina (2005, background): “In elephant seals there is a clear relationship between juvenile survival and the mass of individuals at weaning (McMahon et al., 2000, 2003).”
Adult female survival, population trend, and the implications of early primiparity in a capital breeder, the southern elephant seal (Mirounga leonina) (2004, background): “, 2001b), a fitness cost in terms of reduced offspring survival associated with early primiparity would presumably entail reductions in post-weaning and first year (McMahon et al., 2000) and juvenile survival (Coulson et al.”
Linking Behavior to Vital Rates to Measure the Effects of Non‐Lethal Disturbance on Wildlife (2015, background): “Alternatively, a reduction in fetal growth could indirectly affect vital rates by reducing the size of the calf at birth (Kovacs & Lavigne 1986), and consequently offspring survival (McMahon et al. 2000), but again empirical data for minke whales are missing.”
Using short-term measures of behaviour to estimate long-term fitness of southern elephant seals (2014, methodology): “…et al.: Behaviour and fitness in elephant seals between a species’ vital rates and population growth are well-documented (e.g. Caswell 2001), and the links between health and vital rates of southern elephant seals have been quantified (Arnbom et al. 1993, McMahon et al. 2000, 2003).”
Paired-laser photogrammetry as a simple and accurate system for measuring the body size of free-ranging manta rays Manta alfredi (2010, background): “Since the pup receives no parental care immediately after parturition, larger pups should have greater survivorship (e.g. McMahon et al. 2000).”
Loyalty pays: potential life history consequences of fidelity to marine foraging regions by southern elephant seals (2004, methodology): “…may be no shorter-term advantage of fidelity as measured by weight gain (indeed, there may be an immediate disadvantage for that year’s reproductive output, McMahon et al. 2000b), this behaviour may serve to maximize net energy gain over an animal’s lifetime (Perry & Pianka 1997; Schmidt 2001).”
Circumpolar habitat use in the southern elephant seal: implications for foraging success and population trajectories (2016, methodology): “…and females that breed on the islands of the Antarctic Peninsula and South Georgia are larger than those from other breeding sites (Burton et al. 1997, Postma et al. 2013), which may confer an advantage in terms of foraging success, and ultimately offspring survival (McMahon et al. 2000a, 2003).”
Noninvasive unmanned aerial vehicle provides estimates of the energetic cost of reproduction in humpback whales (2016, background): “Although not documented for baleen whales, maternal body condition in other marine mammals, such as pinnipeds, influences offspring birth and weaning mass (Boltnev and York 2001, Bowen et al. 2001), which, in turn, influences offspring survival (McMahon et al. 2000).”
Maternal body size and condition determine calf growth rates in southern right whales (2018, background): “In many mammalian and avian species, conditions experienced during early offspring development af - fect subsequent survival and reproductive performance (Lindström 1999, McMahon et al. 2000).”
Interannual variation in the post‐weaning and juvenile survival of subantarctic fur seals: influence of pup sex, growth rate and oceanographic conditions (2005, background): “The importance of early condition in future survival and fitness has been demonstrated previously in two phocid seal studies (McMahon et al. 2000; Hall et al. 2001) but not yet on”
