Respiratory function in voluntary participating Patagonia sea lions in sternal recumbency [PDF]
Frontiers in Physiology, 2016 We measured esophageal pressures (n=4), respiratory flow rates (n=5), and expired O2 and CO2 (n=4) in five adult Patagonia sea lions (Otaria flavescens, body mass range 94.3-286.0 kg) during voluntary breaths while laying down.

Anthropozoonotic Endoparasites in Free-Ranging "Urban" South American Sea Lions (Otaria flavescens). [PDF]
J Vet Med, 2016 The present study represents the first report on the gastrointestinal endoparasite fauna of a free-ranging “urban” colony of South American sea lions (Otaria flavescens) living within the city of Valdivia, Chile. A total of 40 individual faecal samples of South American sea lions were collected during the year 2012 within their natural habitat along ...

Change in the foraging strategy of female South American sea lions (Carnivora: Pinnipedia) after parturition [PDF]
Scientia Marina, 2010 This study tests the hypothesis that female South American sea lions shift from off-shore, pelagic prey to coastal, benthic prey after parturition in order to reduce the foraging trip duration and hence the time pups remain unattended on the beach ...
