(Universidad de Valparaíso, 2019)
Seasonal variation in the abundance of South American sea lions Otaria flavescens (Shaw, 1800) in Chañaral Island, Reserva Nacional Pingüino de Humboldt, Chile
(Universidad de Valparaíso. Facultad de Ciencias del Mar, 2009)
Strategies for segregation during foraging in sympatric otariids of the Peruvian upwelling Humboldt Current System
(Inter-Research, 2022)
The competitive exclusion principle predicts that species exhibit segregation mechanisms to coexist. In the Humboldt Current System, South American sea lions Otaria byronia (SASL) coexist with South American fur seals ...
Trends in sympatric otariid populations suggest resource limitations in the Peruvian Humboldt Current System
(Elsevier, 2021)
Sympatric species evolve mechanisms to avoid competition and coexist. In the Humboldt Current System (HCS), populations of South American sea lions (SASL, Otaria byronia) and South American fur seals (SAFS, Arctocephalus ...
Effective population size for South American sea lions along the Peruvian coast: The survivors of the strongest El Niño event in history
(Crambridge University Press, 2012)
The South American sea lion, Otaria flavescens, has been considered vulnerable and under the threat of extinction in Peru due to the drastic demographic changes as a result of the impact of low food availability and the ...
Temporal variability in stable isotope ratios of C and N in the vibrissa of captive and wild adult South American sea lions Otaria byronia : More than just diet shifts
(Wiley Blackwell Publishing, Inc, 2017-10)
We analyzed the d13C and d15N values in the vibrissae of captive adult breeding South American sea lions (Otaria byronia) fed at a constant diet and then used thisinformation to analyze the change in stable isotope values ...
Allometry of the Postnatal Cranial Ontogeny and Sexual Dimorphism in Otaria byronia (Otariidae)
(Springer, 2013-01-31)
We studied the cranial postnatal ontogeny of Otaria byronia in order to detect sexual dimorphism in allometric terms, analyzing the rate of growth of functional variables linked to specific capacities as bite and head ...
