Abstract. Rapid change Air temperatures during winter along the western Antarctic Peninsula have increased 10 degrees Fahrenheit over the last 60 or so years. A young leopard seal is treating Owhiro Bay in Wellington as a rest stop, and residents have been asked to keep their distance. "I translate what the scientists are telling me. The team were here to capture the changes in Antarctica faced during climate change and the dynamic changes facing the habitat of Antarctica’s top apex predators – the leopard seal. If we lose ice, we stand to lose an entire ecosystem.

The Amur leopard (Panthera pardus orientalis) is a leopard subspecies native to the Primorye region of southeastern Russia and northern China. Sea ice … National Geographic photographer Paul Nicklen uses his camera to reveal the graceful and feared leopard seal, a species threatened by climate change. They need ice floes to rest on between hunts. Leopard seal attacks appear to fall off dramatically after crabeaters reach one year of age. It was considered as one of the rarest cats on Earth. The seasonal increase in leopard seal δ 15 N values, and thus fur seal in their diet, was predictably related to larger body size; it may also be forcing reductions to the largest Antarctic fur seal colony in the Antarctic Peninsula. Crabeater seals are protected by the Antarctic Treaty and the Convention for the Conservation of Antarctic Seals. Leopard seals are solitary, and widely dispersed at low densities throughout the circumpolar Antarctic pack ice (Fig.

After considering their responses to recent changes in environmental features, as well as projected and current changes to their habitat our conclusions are that the distribution and abundance of 1) crabeater and Weddell seals will be negatively affected by changes in the extent, persistence and type of annual sea ice, 2) Ross and leopard seal will be the least negatively influenced by changes in pack ice characteristics, although, as may be the case … Our ensemble sampling approach reduces historical biases … Along the way the team faced the challenges of a bumpy Drake Passage, sub-zero water temps and the build-up of snow and ice, yet ticked all its requirements (including capturing some breathtaking aerials courtesy of … As the climate continues to change, many fur seal pups are not surviving to adulthood and the population is declining." In 2007, only 19–26 wild leopards were estimated to survive in southeastern Russia and northeastern China. The effect of global climate change on the formation and extent of antarctic pack ice, and crabeater seal prey, poses an unknown threat to this ice-dependent species. "I call myself an interpreter and a translator," says Nicklen. It is listed as Critically Endangered on the IUCN Red List. Leopard seals, like grizzlies, are solitary creatures that usually stake out vast territories offshore. The team were here to capture the changes in Antarctica faced during climate change and the dynamic changes facing the habitat of Antarctica’s top apex predators – the leopard seal. Climate change will have a significant impact on the seals of Antarctica, the Weddell (Leptonychotes weddellii), crabeater (Lobodon carcinophagus), leopard (Hydrurga leptoynx), Ross (Ommatophoca rossii), southern elephant (Mirpunga leonina) andAntarctic fur seal (Arctocephalus gazella).
