Steeple Jason
Steeple Jason Island is a small island west of Grand Jason Island. It is a part of the Jason Islands in the Falkland Islands. Along with Grand Jason, it is one of the "Islas los Salvajes" in Spanish (the Jasons being divided into two groups in that language). Population and geography None of the Jason Islands has ever been properly inhabited. Steeple Jason was used for sheep grazing up until the 1980s. There are the remains of a shearing shed on the island. There is also Steinhart Station, a field research station on the island, built in 2003 for monitoring wildlife. The island is surrounded by low-lying land around the shore which quickly rises to a steep peak, hence the island's name. The island was formerly owned by New York philanthropist Michael Steinhardt, who later donated it to the Bronx Zoo-based Wildlife Conservation Society. Wildlife Steeple Jason is home to the largest colony of black-browed albatrosses in the world. Over 70% of the global population of black-brow ...

Slender-billed Prion
The slender-billed prion (''Pachyptila belcheri'') or thin-billed prion, is a species of petrel, a seabird in the family Procellariidae. It is found in the southern oceans. Taxonomy The slender-billed prion was species description, formally described in 1912 by the Australian born ornithologist Gregory Mathews under the binomial name ''Heteroprion belcheri''. The prion is now placed with the other prions in the genus ''Pachyptila'' that was introduced in 1811 by the German zoologist Johann Karl Wilhelm Illiger. The genus name combines the Ancient Greek ''pakhus '' meaning "dense" or "thick" with ''ptilon'' meaning "feather" or "plumage". The specific epithet ''belcheri'' was chosen in recognition of the Australian judge and amateur ornithologist Charles Frederic Belcher, Charles Belcher who had found the first specimens dead on a beach near the town of Geelong in the Australian state of Victoria (Australia), Victoria. The species is considered to be monotypic: no subspecies a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Blue Planet
''The Blue Planet'' is a British nature documentary series created and produced by the BBC. It premiered on 12 September 2001 in the United Kingdom. It is narrated by David Attenborough. Described as "the first ever comprehensive series on the natural history of the world's oceans", each of the eight 50-minute episodes examines a different aspect of marine life. The underwater photography included creatures and behaviour that had previously never been filmed. The series won a number of Emmy and BAFTA TV awards for its music and cinematography. The executive producer was Alastair Fothergill and the music was composed by George Fenton. Attenborough narrated this series before presenting the next in his 'Life' series of programmes, ''The Life of Mammals'' (2002), and the same production team created ''Planet Earth'' (2006). A sequel series, ''Blue Planet II'' was aired on BBC One in 2017. Background The series took almost five years to make, involving nearly 200 filming locati ...

Overfishing
Overfishing is the removal of a species of fish (i.e. fishing) from a body of water at a rate greater than that the species can replenish its population naturally (i.e. the overexploitation of the fishery's existing fish stock), resulting in the species becoming increasingly underpopulated in that area. Overfishing can occur in water bodies of any sizes, such as ponds, wetlands, rivers, lakes or oceans, and can result in resource depletion, reduced biological growth rates and low biomass levels. Sustained overfishing can lead to critical depensation, where the fish population is no longer able to sustain itself. Some forms of overfishing, such as the overfishing of sharks, has led to the upset of entire marine ecosystems. Types of overfishing include: growth overfishing, recruitment overfishing, ecosystem overfishing. The ability of a fishery to recover from overfishing depends on whether its overall carrying capacity and the variety of ecological conditions are suitable for t ...

Tussac Grass
''Poa flabellata'', commonly known as tussac grass or just tussac, is a tussock grass native to southern South America, the Falkland Islands, South Georgia and other islands in the South Atlantic. There are also two isolated records from the herbarium at the French Muséum national d'histoire naturelle for the Île Amsterdam in the Indian Ocean. It was introduced to Shetland, Scotland for basket making in 1844, and possibly as a source of fodder because of its ability to grow in hostile conditions.. It grows in dense clumps, usually about high (although they can be much taller), on wet coastal land and is a dominant feature of much of the landscape. Associated organisms The plant community dominated by ''P. flabellata'' is widely used by birds and mammals. Breeding colonies of southern fur seal, elephant seal, Magellanic penguin, macaroni penguin, and albatrosses are all found amongst tussac grass on South Georgia and elsewhere. The austral thrush is predominantly found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kelp
Kelps are large brown algae seaweeds that make up the order Laminariales. There are about 30 different genera. Despite its appearance, kelp is not a plant - it is a heterokont, a completely unrelated group of organisms. Kelp grows in "underwater forests" (kelp forests) in shallow oceans, and is thought to have appeared in the Miocene, 5 to 23 million years ago. The organisms require nutrient-rich water with temperatures between . They are known for their high growth rate—the genera ''Macrocystis'' and '' Nereocystis'' can grow as fast as half a metre a day, ultimately reaching .Thomas, D. 2002. ''Seaweeds.'' The Natural History Museum, London, p. 15. Through the 19th century, the word "kelp" was closely associated with seaweeds that could be burned to obtain soda ash (primarily sodium carbonate). The seaweeds used included species from both the orders Laminariales and Fucales. The word "kelp" was also used directly to refer to these processed ashes. Description In most kelp ...

Fur Seal
Fur seals are any of nine species of pinnipeds belonging to the subfamily Arctocephalinae in the family '' Otariidae''. They are much more closely related to sea lions than true seals, and share with them external ears (pinnae), relatively long and muscular foreflippers, and the ability to walk on all fours. They are marked by their dense underfur, which made them a long-time object of commercial hunting. Eight species belong to the genus '' Arctocephalus'' and are found primarily in the Southern Hemisphere, while a ninth species also sometimes called fur seal, the Northern fur seal (''Callorhinus ursinus''), belongs to a different genus and inhabits the North Pacific. The fur seals in ''Arctocephalus'' are more closely related to sea lions than they are to the Northern fur seal, but all three groups are more closely related to each other than they are to true seals. Taxonomy Fur seals and sea lions make up the family Otariidae. Along with the Phocidae and Odobodenidae, otta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tussac-bird
The blackish cinclodes (''Cinclodes antarcticus'') is a passerine bird of the genus ''Cinclodes'' belonging to the ovenbird family Furnariidae. It is native to the southern tip of South America including the Falkland Islands where it is known as the tussac-bird or tussock-bird. It is often very tame and will approach humans closely. Description It is 18 to 23 cm long. The sexes are similar and their plumage is almost entirely dark brown. The throat is slightly paler with some buff speckling, there is a hint of a pale stripe over the eye and there is a faint reddish-brown bar on the wing. The bill is quite long, stout and slightly downcurved with a pale yellow spot at the base (lacking in Falkland birds). The song and calls are loud and high-pitched. The trilling song may be uttered from a perch or in flight. Habitat and range The blackish cinclodes is a bird of coasts and islands, commonly found among rocks, kelp on beaches and in areas of tussac grass. The nominate subs ...

Striated Caracara
The striated caracara (''Phalcoboenus australis'') is a bird of prey of the family Falconidae. In the Falkland Islands, it is known as the Johnny rook, probably named after the Johnny penguin (gentoo penguin). Description The adults' plumage is almost black in color, while the legs and lores are orange and the neck has silver striations. Chicks have chestnut down, which they lose after their first molt. Juveniles (i.e., after fledging until entering fourth year) have brown plumage with chestnut striations on nape and breast that deepen as they age. Full adult plumage is acquired after the fifth molt (i.e., entering fourth year), though the beak does not reach full adult coloration until the fifth year. Distribution and habitat The species breeds on coastal islands off Tierra del Fuego, through the Chilean fjords, and the outer islands of the Falklands archipelago. Although logistical challenges prohibit a comprehensive survey of the mainland population, the Falklands is thought t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gentoo Penguin
The gentoo penguin ( ) (''Pygoscelis papua'') is a penguin species (or possibly a species complex) in the genus ''Pygoscelis'', most closely related to the Adélie penguin (''P. adeliae'') and the chinstrap penguin (''P. antarcticus''). The earliest scientific description was made in 1781 by Johann Reinhold Forster with a type locality in the Falkland Islands. The species calls in a variety of ways, but the most frequently heard is a loud trumpeting, which the bird emits with its head thrown back. Names The application of "gentoo" to the penguin is unclear. '' Gentoo'' was an Anglo-Indian term to distinguish Hindus from Muslims. The English term may have originated from the Portuguese ''gentio'' ("pagan, gentile"). Some speculate that the white patch on the bird's head was thought to resemble a turban. It may also be a variation of another name for this bird, "Johnny penguin", with Johnny being in Spanish and sounds vaguely like gentoo. The Johnny rook, a predator, is likely ...
