Phylogeography of California and Galápagos sea lions and population structure within the California sea lion
(Marine Biology, 2009)
We investigate the phylogeography of California (Zalophus californianus) and Galápagos (Z. wollebaeki) sea lions and describe within-population structure for the California sea lion based on mitochondrial DNA. Fifty ...
Helminth and respiratory mite lesions in Pinnipeds from Punta San Juan, Peru
(Springer, 2018)
The tissues and parasites collected from Peruvian fur seals (Arctocephalus australis) and South American sea lions (Otaria byronia) found dead at Punta San Juan, Peru were examined. The respiratory mite, Orthohalarachne ...
Travel for sex: Long-range breeding dispersal and winter haulout fidelity in southern sea lion males
(Elsevier Gmbh, 2016-01)
Southern sea lions (Otaria flavescens; SSLs) have a polygynous mating system and a prolonged social-sexual maturation period for males. Male haulouts are common in this species, with some very distant from central breeding ...
Ontogenic dietary changes in South American sea lions
(Wiley Blackwell Publishing, Inc, 2009-11)
Stable isotopes of carbon and nitrogen in the skull bones of South American sea lions Otaria flavescens from the Chubut province (Argentina) were analysed to determine whether their feeding habits change during ontogeny. ...
Mamíferos marinos II (carnívoros)
(Acuario Nacional de Cuba, La Habana, 2010)
Número de la revista dedicado a los carnívoros marinos, grupo que integran leones y lobos marinos, focas, morsas, nutrias y osos polares, que de forma didáctica ofrece información sobre sus orígenes, taxonomía, distribución ...
Past exploitation of California sea lions did not lead to a genetic bottleneck in the Gulf of California
(Ciencias Marinas, 2010)
Human exploitation can lead to genetic bottlenecks associated with reduced genetic variability and lower fitness. The population of California sea lions (Zalophus californianus) in the Gulf of California, Mexico, was hunted ...
Living on the edge: thermoregulatory behaviour of South American sea lions, Otaria flavescens, at the northern limit of their Atlantic distribution
(Springer Heidelberg, 2019-02)
Terrestrial reproduction presents a thermoregulatory challenge for marine mammals, especially in a context of global warming. Pinnipeds, especially otariids, differ from other marine mammals in that most reproductive ...
Exploitation and Recovery of the South American Sea Lion in the Southwestern Atlantic
(Springer, 2021)
The South American sea lion, Otaria flavescens, is one of the most conspicuous marine mammals along the coasts of the Atlantic and Pacific Oceans. It has a long history of exploitation throughout its range. In the southwestern ...
Climate anomalies influence tooth growth patterns of South American sea lion
(Wiley Blackwell Publishing, Inc., 2021-08)
El Niño-Southern Oscillation (ENSO) and Southern Annular Mode (SAM) indirectly affect tooth growth of marine mammals, through changes in prey abundance, availability, and composition. This is reflected as variation in the ...
Climate-driven changes in sedimentation rate influence phosphorus burial along continental margins of the northwestern Mediterranean
(Elsevier, 2018)
The burial of phosphorus (P) in continental margin sediments is a critical component of the marine reactive P budget, and thus an important factor in marine biological productivity. We determined downcore records of P from ...
