Sensory anatomy of the most aquatic of carnivorans: The Antarctic Ross seal, and convergences with other mammals
(The Royal Society, 2017-10)
Transitions to and from aquatic life involve transformations in sensory systems. The Ross seal, Ommatophoca rossii, offers the chance to investigate the cranio-sensory anatomy in the most aquatic of all seals. The use of ...

Defining conservation status using limited information: The case of Patagonian otters Lontra provocax in Argentina
(Springer, 2010-02)
The Southern river otter or huillín Lontra provocax has been classified as 'endangered', with the loss of riparian forest identified as the main threat to its survival. We used new information on distribution from Argentina ...
Consumption of marine mammals by broadnose sevengill shark Notorynchus cepedianus in the northern and central Patagonian shelf
(Latin American Journal Of Aquatic Mammals, 2003-07)
The study of food habits of the broadnose sevengill shark (Notorynchus cepedianus) based on the observation of the stomach contents of 22 individuals, revealed the importance of marine mammals as part of the shark's diet. ...
Evolutionary transformations of the malleus in pinnipeds, with emphasis on Southern Hemisphere taxa
(University of Amsterdam, 2018-07)
The systematic value of the middle-ear ossicles, in particular the malleus, has been long recognized for diverse groups. We present here systematic work on middle-ear ossicle characters of pinnipeds, focusing on until now ...

Climate change and body size trends in aquatic and terrestrial endotherms: does habitat matter?
(PLoS, 2017)
Several studies have claimed that reduction in body size comprises a nearly universal response to global warming; however, doubts about the validity of this pattern for endothermic species have been raised recently. ...
Mercury Concentration in Liver Tissues of South American Fur Seals (Arctocephalus australis) from Southwestern Atlantic Ocean
(Soc Brasileira Quimica, 2022-04-08)
Mercury (Hg) contamination of oceans is rapidly increasing, however Hg bioaccumulation in pinnipeds has been understudied. Here, we report for the first time Hg concentration in liver tissues of South American fur seals ...
