Ancient female philopatry, asymmetric male gene flow, and synchronous population expansion support the influence of climatic oscillations on the evolution of South American sea lion (Otaria flavescens)
(Public Library of Science, 2017)
The South American sea lion (Otaria flavescens) is widely distributed along the southern Atlantic and Pacific coasts of South America with a history of significant commercial exploitation. We aimed to evaluate the population ...
South American Sea Lion (Otaria favescens, Shaw 1800)
(Springer Nature Switzerland AG, 2021)
The South American sea lion is distributed almost continuously from Zorritos, Peru, on the Pacifc Ocean to Torres, Brazil, on the Atlantic Ocean. The total population was estimated at 445,000 individuals, and the species ...
Trichinella spiralis in a South American sea lion (Otaria flavescens) from Patagonia, Argentina
(Springer, 2018-12)
Trichinella spp. from a sylvatic cycle has been found in several animal species such as pumas (Puma concolor), armadillos (Chaetophractus villosus), rats (Rattus norvegicus), and wild boars (Sus scrofa) in Argentina. ...
Osteometric analysis of south american sea lions (Otaria flavescens) pups from Patagonia. An assessment of their use as indicators for seasonality in archaeological sites
(John Wiley & Sons Ltd, 2014-01-21)
Zooarchaeological analyses of pinniped remains have been scarce in South America because of lack of specific studies of species determination and estimation of age and sex. Nonetheless, the presence of small and unfused ...
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 ...
Diphyllobothrium sprakeri n. sp. (Cestoda: Diphyllobothriidae): a hidden broad tapeworm from sea lions off North and South America
(BioMed Central, 2021-12)
Background: The systematic of several marine diphyllobothriid tapeworms of pinnipeds has been revised in recent years. However, 20 species of Diphyllobothrium from phocids and otariids are still recognized as incertae ...
A hunted population in recovery: Effective population size for South American sea lions from Patagonia
(Brill Academic Publishers, 2012)
Analysing the natural population growth of a large marine mammal after a depletive harvest
(Springer Nature, 2017-07)
An understanding of the underlying processes and comprehensive history of population growth after a harvest-driven depletion is necessary when assessing the long-term effectiveness of management and conservation strategies. ...
Regional variability in diving physiology and behavior in a widely distributed air-breathing marine predator, the South American sea lion (Otaria byronia)
(Company of Biologists Ltd, 2016)
Our understanding of how air-breathing marine predators cope with environmental variability is limited by our inadequate knowledge of their ecological and physiological parameters. Because of their wide distribution along ...
