| digenetic trematodes in south american sea lions from southern brazilian waters. | the aim of this work was to perform a systematic study to detect and quantify the digenetic trematode infections in south american sea lions from the southern brazilian coast. twenty-four south american sea lions, otaria flavescens (carnivora: otaridae), were found dead along the coast of rio grande do sul state, brazil, between june 2010 and september of 2011. two trematode species were found in the intestines of o. flavescens, i.e., stephanoprora uruguayense (digenea: echinostomatidae) and asc ... | 2013 | 23421418 |
| identification of respiratory and gastrointestinal parasites of three species of pinnipeds (arctocephalus australis, arctocephalus gazella, and otaria flavescens) in southern brazil. | in order to improve understanding of parasitism in south american pinnipeds, respiratory and gastrointestinal samples were collected from 12 arctocephalus australis (south american fur seal), one arctocephalus gazella (antarctic fur seal), and one otaria flavescens (south american sea lion). ova and larvae were microscopically identified from fecal samples and respiratory secretions collected from live a. australis undergoing rehabilitation at centro de recuperação de animais marinhos (cram-furg ... | 2016 | 27010274 |
| occupancy dynamics of south american sea-lions in brazilian haul-outs. | along the brazilian coast only two haul-outs of south american sea lions (otaria flavescens) are known: ilha dos lobos and molhe leste, both located in the southernmost state of brazil, rio grande do sul. most sea lions observed in these haul-outs are adult and sub-adult males. it is supposed that the species' presence in these areas is due to food supply and absence of parental assistance by males. this study analysed the use of these haul-outs by o. flavescens between 1993 and 2002 based on co ... | 2013 | 24789403 |
