ÃŽle Aux Cochons (Crozet)
Île aux Cochons, or Pig Island, is an uninhabited island in the subantarctic Crozet Islands, Crozet Archipelago. With an area of it is the third largest island of the group. Administratively, it is part of the French Southern and Antarctic Lands. Description Île aux Cochons is the westernmost island of the archipelago, lying some 30 km north-west of Île des Pingouins and 15 km south-west of the Îlots des Apôtres. It is an eroded volcanic dome, scattered with inactive craters, and a coastline consisting partly of low cliffs. Introduced species include cats, rabbits and house mouse, mice. The introduced pigs that gave the island its name have been eradicated. There is no human infrastructure and visits by researchers are rare. Important Bird Area The island has been identified as an Important Bird Area (IBA) by BirdLife International as a breeding site for seabirds, and notably for its large penguin populations. It held the world's largest king penguin bird ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crozet Islands
The Crozet Islands (; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command, Julien-Marie Crozet, landed on ÃŽle de la Possession, claiming the archipelago for France. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, naming the western group ''Marion'' and the eastern group ''Crozet''. In the following years, sealers visiting the islands referred to both the eastern and western groups as the Crozet Islands, and Marion Island became the name of the larger of the two Prince Edward ...

Wandering Albatross
The snowy albatross (''Diomedea exulans''), also known as the wandering albatross, white-winged albatross, or goonie, is a large seabird from the family Diomedeidae Albatrosses, of the biological family (biology), family Diomedeidae, are large seabirds related to the procellariidae, procellariids, storm petrels, and diving petrels in the order Procellariiformes (the tubenoses). They range widely in the So ...; they have a circumpolar range in the Southern Ocean. It is the largest species of albatross and was long considered to be the same species as the Tristan albatross and the Antipodean albatross. Together with the Amsterdam albatross, it forms the wandering albatross Cryptic species complex, species complex, which some began referring to more recently as "snowy". The snowy albatross is one of the two largest members of the genus ''Diomedea'' (the great albatrosses), being similar in size to the southern royal albatross. It has the greatest known wingspan of any living bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uninhabited Islands Of France
The list of uninhabited regions includes a number of places around the globe. The list changes year over year as human beings migrate into formerly uninhabited regions, or migrate out of formerly inhabited regions. Definitions The exact definition of what makes a place "uninhabited" is not simple. Nomadic hunter-gather and pastoral societies live in extremely low population densities and range across large territories where they camp, rather than staying in any one place year-round. During the height of settler colonialism many European governments declared huge areas of the New World and Australia to be ''Terra nullius'' (land belonging to no one), but this was done to create a legal pretext to annex them to European empires; these lands were not, and are not uninhabited. While some communities are still nomadic, there are many remote and isolated communities in the less populated parts of the world that are separated from each other by hundreds or thousands kilometres ...

Volcanoes Of The French Southern And Antarctic Lands
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is stretching a ...

Important Bird Areas Of The Crozet Islands
Importance is a property of entities that matter or make a difference. For example, World War II was an important event and Albert Einstein was an important person because of how they affected the world. There are disagreements in the academic literature about what type of difference is required. According to the causal impact view, something is important if it has a big causal impact on the world. This view is rejected by various theorists, who insist that an additional aspect is required: that the impact in question makes a value difference. This is often understood in terms of how the important thing affects the well-being of people. So in this view, World War II was important, not just because it brought about many wide-ranging changes but because these changes had severe negative impacts on the well-being of the people involved. The difference in question is usually understood counterfactually as the contrast between how the world is and how the world would have been withou ...

Subantarctic Fur Seal
The subantarctic fur seal (''Arctocephalus tropicalis'') is a species of arctocephaline found in the southern parts of the Indian, Pacific, and Atlantic Oceans. It was first described by Gray in 1872 from a specimen recovered in northern Australia—hence the inappropriate specific name ''tropicalis''. Description The subantarctic fur seal is medium in size compared with other fur seals. The two sexes are strongly sexually dimorphic: males grow to 2m and 160 kg, whereas females are substantially smaller—1.4m and 50 kg. Subantarctic fur seals have creamy-orange chests and faces. Their bellies are more brownish. Males have a dark grey to black back, while females are a lighter grey. Males have a characteristic dark tuft of hair on the top of their head that stands erect when they are excited. Pups are black at birth, but molt at about 3 months old. The snout is short and flat, and the flippers are short and broad. Subantarctic fur seals live for about 20–2 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctic Fur Seal
The Antarctic fur seal (''Arctocephalus gazella'') is one of eight seals in the genus '' Arctocephalus'', and one of nine fur seals in the subfamily Arctocephalinae. Despite what its name suggests, the Antarctic fur seal is mostly distributed in Subantarctic islands and its scientific name is thought to have come from the German vessel SMS Gazelle, which was the first to collect specimens of this species from the Kerguelen Islands. Taxonomy Antarctic fur seals are member of the genus ''Arctocephalus''. Recently, a proposal was made to reassign this species to the resurrected genus ''Arctophoca''. Antarctic fur seals may be confused with southern otariids that share their range, like Subantarctic (''A. tropicalis''), New Zealand (''A. forsteri''), and South American fur seals (''A. australis''), and the Juan Fernandez fur seal (''A. phillippii''), as well as the South American (''Otaria flavescens'') and New Zealand sea lions (''Phocarctos hookeri'').

Southern Elephant Seal
The southern elephant seal (''Mirounga leonina'') is one of two species of elephant seals. It is the largest member of the clade Pinnipedia and the order Carnivora, as well as the largest extant marine mammal that is not a cetacean. It gets its name from its massive size and the large proboscis of the adult male, which is used to produce very loud roars, especially during the breeding season. A bull southern elephant seal is about 40% heavier than a male northern elephant seal (''Mirounga angustirostris''), which is nearly twice the weight of a male walrus (''Odobenus rosmarus''), or 6–7 times heavier than the largest living mostly terrestrial carnivorans, the Kodiak bear and the polar bear. Taxonomy The southern elephant seal was one of the many species originally described by Swedish zoologist Carl Linnaeus in the landmark 1758 10th edition of his ''Systema Naturae'', where it was given the binomial name of ''Phoca leonina''. John Edward Gray established the genus ''Mirou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eaton's Pintail
Eaton's pintail (''Anas eatoni'') is a dabbling duck of the genus ''Anas''. It is also known as the southern pintail. The species is restricted to the island groups of Kerguelen and Crozet in the southern Indian Ocean. It resembles a small female northern pintail. It was named after the English explorer and naturalist Alfred Edwin Eaton. It is threatened by introduced species, particularly feral cats, which prey on it, particularly during the post-breeding molt, when it is unable to fly. Taxonomy While previously considered a subspecies of northern pintail, the Eaton’s pintail is much smaller (one female Eaton’s pintail weighed 450 g, while the mean mass of female northern pintails is 871 g) and the male Eaton's pintail is female-like in patterning, unlike the sexually dimorphic northern pintail.del Hoyo, J., N. Collar, and G. M. Kirwan (2020). Eaton's Pintail (Anas eatoni), version 1.0. In Birds of the World (J. del Hoyo, A. Elliott, J. Sargatal, D. A. Christie, and E. ...
