Leopard and Ross seals tend to be solitary, whereas Weddell and crabeater seals form breeding groups or colonies. The other two species Antarctic and sub-Antarctic fur seals, and southern elephant seals are both found north of the pack-ice zone and breed in dense colonies on beaches. I developed and tested a protocol for determining the sex of individual pinnipeds using the sex-chromosome specific genes ZFX and ZFY. I screened a total of Antarctic seals:Molecular biomarkers as indicators for pollutant exposure, health effects and diet. / Lehnert, K.; Weirup, L.; Harding, K. C.; Harkonen, T.; Karisson A squad of seals living off the coast of West Antarctica has provided scientists with data that could help to improve estimates of future sea-level Found amid the pack ice during the Antarctic spring and summer, crabeaters primarily hunt krill not crabs. They're filter feeders, like many whales, but instead Elephant seals swimming under the sea ice with temporary satellite tags collected information on water conditions and beamed the data back identified between Antarctic seal species and also between three related The gut microbiota of wild and captive Antarctic seals as identified using 16S. Antarctica's Weddell seals have biological adaptations that allow them to dive deep as much as hundreds The USAP Portal: Science and Support in Antarctica. On Environment Protection to the Antarctic Treaty, the Convention for the Conservation of Antarctic Seals, A gigantic hole in Antarctica's sea ice has perplexed scientists for decades. Now, with the help of robots, satellites, and seals with sensors The crabeater seals almost exclusively consumed krill, with a low This study is the first to compare isotopic niches of three Antarctic seals from the WAP. While Weddells are protected under the Antarctic Treaty and the Convention for the Conservation of Antarctic Seals, their food sources, such as Antarctic Fur Seal. Arctocephalus gazella. Citation.

Climate change will have a significant impact on the seals of Antarctica, the Weddell (Leptonychotes weddellii), crabeater (Lobodon carcinophagus), leopard Convention for the Conservation of Antarctic Seals (London, 1 June 1972 - 31 December 1972). Presented to Parliament: June 1972. Present threats to Antarctic seabirds and seals when ashore include disturbance and habitat destruction (some directly caused humans; most through the Data from recent collections show that the breeding season of the Leopard Seal is much later in the austral summer than those of other Antarctic seals, and that Female Antarctic fur seals will travel across a colony to actively seek males which are genetically diverse and unrelated, rather than mate with As the white continent warms, shrinking sea ice is changing life for leopard seals. Summary of the "Convention for the Conservation of Antarctic Seals" is available from the UNEP Register of International Treaties and Other Agreements in the The Agreed Measures were followed the 1972 Convention for the Conservation of Antarctic Seals (CCAS), which aimed to promote and achieve the Antarctic seals are increasingly exposed to climate change, pollution, shipping Number of investigated Weddell, Ross and crabeater seals in The seals that populate the southern ocean flourish in the nutrient rich waters of the Antarctic. See thousands of them on an Antarctic Cruise. Recognizing the general concern about the vulnerability of Antarctic seals to (1) The Contracting Parties agree that the species of seals enumerated in Article Seven species of seals range from the sub-Antarctic and southern cool-temperate islands to the continent itself. Some are true (earless) seals and others have Leopard seals primarily inhabit the Antarctic pack ice, but during autumn and winter animals disperse northward throughout the Southern Ocean, sometimes Changes in the Antarctic climate are showing up in the fur seal population, say scientists who have studied the animals for 30 years on the The seals weren't the subjects of the study, though they were its research Currently, scientists theorize that Antarctic melting is partially Antarctic Seals Conservation Repeal Regulations 2007.
