So happy together: juvenile crabeater seal behavior improves lice transmission
(Springer, 2020-05)
Lice from family Echinophthiriidae are of the few insects that have successfully colonized marine environment living as ectoparasites of pinnipeds, i.e., sea lions, seals, and the walrus. They have developed unique adaptations ...
Aggregation of mummified adult crabeater seals (Pinnipedia: Phocidae) in the eastern Antarctic Peninsula: age and sex structure, taphonomy and cause of death
(Cambridge University Press, 2014-12)
In Antarctica, crabeater seals tend to strand as immature animals with disorientation, due to their inexperience, given as the probable cause. In 2012 and 2013, we examined a group of 80 mummified crabeater seals on Seymour ...
Leukocyte counts in three sympatric pack-ice seal species from the western Antarctic Peninsula
(Springer, 2019-10)
Global warming, and its consequences, constitute one of the main stressors for organisms worldwide, affecting different factors such as the geographic distribution and the abundance of parasites, which in turn can affect ...
Antarctic Radiocarbon Reservoir: The case of the mummified crabeater seals (Lobodon carcinophaga) in Bodman Cape, Seymour Island, Antarctica
(University of Arizona. Department of Geosciences, 2011-03)
At least 50% of the world’s seal population is distributed in the pack-ice region surrounding Antarctica. Among the Antarctic seals, Lobodon carcinophaga (commonly known as “crabeater seals”) are the most abundant. This ...
New records of mummified crabeater seals on islands bordering Admiralty Sound, Weddell Sea
(Cambridge University Press, 2019-06)
Ninety-six mummified crabeater seals discovered at Seymour Island (Isla Marambio) are reported. Each specimen was georeferenced, photographed and assigned to five different taphonomic states. Previous work stated that seals ...
Redescription of Antarctophthirus lobodontis (Anoplura: Echinophthiriidae) from the crabeater seal and identification key for Antarctic lice.
(Springer, 2016-04)
The Anoplura (Phthiraptera) is composed of lice parasitizing mainly terrestrial mammals, but a few members have been able to adapt to the marine environment. The latter are included in the family Echinophthiriidae, a ...
Large and in charge: cortisol levels vary with sex, diet, and body mass in an Antarctic predator, the leopard seal
(2023)
Evaluating physiological responses in the context of a species’ life history, demographics, and ecology is essential to understanding the health of individuals and populations. Here, we measured the main mammalian ...
