Wildlife Of The Falkland Islands
The wildlife of the Falkland Islands is quite similar to that of Patagonia. The Falkland Islands have no native reptiles or amphibians, and the only native land mammal, the warrah, is now extinct. However, a large number of bird species have been seen around the islands, and many of them breed on the smaller islands of the archipelago. Insects play a large role in the ecosystem of the islands, and over 200 species have been recorded. The waters around the Falkland Islands sustain many animals, including a large number of marine mammals. Three pinniped species breed on the islands. There are no trees native to the area, leading to a wide proliferation of grass species. This includes tussac grass, the dense leaves of which provide a micro-climate for many bird and invertebrate species. Small bushes are also found, along with a small number of freshwater plants. The plant species vary with different factors such as the fertility of the soil, the humidity, and altitude. There is a lac ...

West Falkland
West Falkland ( es, Isla Gran Malvina) is the second largest of the Falkland Islands in the South Atlantic. It is a hilly island, separated from East Falkland by the Falkland Sound. Its area is , 37% of the total area of the islands. Its coastline is long. Population The island has fewer than 200 people, scattered around the coastline. The largest settlement is Port Howard on the east coast, which has an airstrip. Other settlements include Albemarle, Chartres, Dunnose Head, Fox Bay, Fox Bay West, Hill Cove, Port Stephens, and Roy Cove, most of which are linked by road and also have airstrips and harbours. In 1986, the population was 265, in 2001, it had fallen to 144 and rose to 160 in 2016. Because West Falkland is outside Stanley or RAF Mount Pleasant on East Falkland it is considered part of the "camp", a Falklander term for the area outside the main settlement. Geography and wildlife West Falkland is hillier on the side closest to East Falkland. The principal mounta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cetacean
Cetacea (; , ) is an infraorder of aquatic mammals that includes whales, dolphins, and porpoises. Key characteristics are their fully aquatic lifestyle, streamlined body shape, often large size and exclusively carnivorous diet. They propel themselves through the water with powerful up-and-down movement of their tail which ends in a paddle-like fluke, using their flipper-shaped forelimbs to maneuver. While the majority of cetaceans live in marine environments, a small number exclusively reside in brackish water or fresh water. Having a cosmopolitan distribution, they can be found in some rivers and all of Earth's oceans, and many species inhabit vast ranges where they migrate with the changing of the seasons. Cetaceans are famous for their high intelligence and complex social behaviour as well as for the enormous size of some of the group's members, such as the blue whale which reaches a maximum confirmed length of 29.9 meters (98 feet) and a weight of 173 tonnes (190 short tons ...

Southern Sea Lion
The South American sea lion (''Otaria flavescens'', formerly ''Otaria byronia''), also called the southern sea lion and the Patagonian sea lion, is a sea lion found on the western and southeastern coasts of South America. It is the only member of the genus ''Otaria''. The species is highly sexually dimorphic. Males have a large head and prominent mane. They mainly feed on fish and cephalopods and haul out on sand, gravel, rocky, or pebble beaches. In most populations, breeding males are both territorial and harem holding; they establish territories first and then try to herd females into them. The overall population of the species is considered stable, estimated at 265,000 animals. Naming The South American sea lion was classified as ''Otaria flavescens'' by George Shaw in 1800 and as ''Otaria byronia'' by Henri Marie Ducrotay de Blainville in 1820. The two nomenclatures were historically used interchangeably, but ''O. flavescens'' has become the preferred name. The specie ...

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''), twice as heavy as a male walrus (''Odobenus rosmarus''), and 6–7 times heavier than the largest living mostly-terrestrial carnivoran, the polar bear (''Ursus maritimus'') and the Kodiak bear (''Ursus arctos middendorffi''),. 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''.

Leopard Seal
The leopard seal (''Hydrurga leptonyx''), also referred to as the sea leopard, is the second largest species of seal in the Antarctic (after the southern elephant seal). Its only natural predator is the orca. It feeds on a wide range of prey including cephalopods, other pinnipeds, krill, fish, and birds, particularly penguins. It is the only species in the genus ''Hydrurga''. Its closest relatives are the Ross seal, the crabeater seal and the Weddell seal, which together are known as the tribe of Lobodontini seals. The name ''hydrurga'' means "water worker" and ''leptonyx'' is the Greek for "thin-clawed". Taxonomy French zoologist Henri Marie Ducrotay de Blainville described the leopard seal in 1820. Description The leopard seal has a distinctively long and muscular body shape when compared to other seals, but it is perhaps best known for its massive jaws, which allow it to be one of the top predators in its environment. The front teeth are sharp like those of other carnivores, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Commerson's Dolphin
Commerson's dolphin (''Cephalorhynchus commersonii''), also referred to by the common names jacobita, skunk dolphin, piebald dolphin, panda dolphin, or tonina overa (in South America), is a small oceanic dolphin of the genus ''Cephalorhynchus''. Commerson's dolphin has two geographically-isolated but locally-common subspecies. The principal subspecies, ''C.c.commersonii'', has sharply-delineated black-and-white patterning and is found around the tip of South America. The secondary subspecies, ''C.c.kerguelenensis'', is larger than ''C.c.commersonii'', has a less-sharply delineated dark and light grey patterning with a white ventral band, and is found around the Kerguelen Islands in the Indian Ocean. The dolphin is named after French naturalist Dr Philibert Commerson, who first described them in 1767 after sighting them in the Strait of Magellan. Population and distribution Two disjunct subspecies of the dolphin are found in geographically disparate areas separated by 130° of l ...

Peale's Dolphin
Peale's dolphin (''Lagenorhynchus australis'') is a small dolphin found in the waters around Tierra del Fuego at the foot of South America. It is also commonly known as the black-chinned dolphin or even Peale's black-chinned dolphin. However, since Rice's work Peale's dolphin has been adopted as the standard common name. Taxonomy Though it is traditionally placed in the genus ''Lagenorhynchus'', recent molecular phylogeny, molecular analyses indicate Peale's dolphin is actually more closely related to the dolphins of the genus ''Cephalorhynchus''. If true, this would mean this species must either be transferred to ''Cephalorhynchus'' or be given a new genus of its own. An alternate genus proposed for this species (as well as the Pacific white-sided dolphin, hourglass dolphin and dusky dolphin is the resurrected genus ''Sagmatias''. Some behavioral and morphological data support moving Peale's dolphin to ''Cephalorhynchus''. According to , Peale's dolphin and the ''Cephalorhynchu ...

Killer Whale
The orca or killer whale (''Orcinus orca'') is a toothed whale belonging to the oceanic dolphin family, of which it is the largest member. It is the only extant species in the genus ''Orcinus'' and is recognizable by its black-and-white patterned body. A cosmopolitan species, orcas can be found in all of the world's oceans in a variety of marine environments, from Arctic and Antarctic regions to tropical seas. Orcas have a diverse diet, although individual populations often specialize in particular types of prey. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack baleen whale calves, and even adult whales. Orcas are apex predators, as they have no natural predators. They are highly social; some populations are composed of very stable matrilineal family groups (pods) which are the most stable of any animal species. Their sophisticated hunting techniques and vocal behaviours, which are o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maned Wolf
The maned wolf (''Chrysocyon brachyurus'') is a large canine of South America. It is found in Argentina, Brazil, Bolivia, Peru, and Paraguay, and is almost extinct in Uruguay. Its markings resemble those of foxes, but it is neither a fox nor a wolf. It is the only species in the genus ''Chrysocyon'' (meaning "golden dog"). It is the largest canine in South America, weighing and up to at the withers. Its long, thin legs and dense reddish coat give it an unmistakable appearance. The maned wolf is a crepuscular and omnivorous animal adapted to the open environments of the South American savanna, with an important role in the seed dispersal of fruits, especially the wolf apple (''Solanum lycocarpum''). The maned wolf is a solitary animal. It communicates primarily by scent marking, but also gives a loud call known as "roar-barking". This mammal lives in open and semi-open habitats, especially grasslands with scattered bushes and trees, in the Cerrado of south, central-west, and ...

University Of California, Los Angeles
The University of California, Los Angeles (UCLA) is a public land-grant research university in Los Angeles, California. UCLA's academic roots were established in 1881 as a teachers college then known as the southern branch of the California State Normal School (now San José State University). This school was absorbed with the official founding of UCLA as the Southern Branch of the University of California in 1919, making it the second-oldest of the 10-campus University of California system (after UC Berkeley). UCLA offers 337 undergraduate and graduate degree programs in a wide range of disciplines, enrolling about 31,600 undergraduate and 14,300 graduate and professional students. UCLA received 174,914 undergraduate applications for Fall 2022, including transfers, making the school the most applied-to university in the United States. The university is organized into the College of Letters and Science and 12 professional schools. Six of the schools offer undergraduate degre ...

Lawn
A lawn is an area of soil-covered land planted with grasses and other durable plants such as clover which are maintained at a short height with a lawnmower (or sometimes grazing animals) and used for aesthetic and recreational purposes. Lawns are usually composed only of grass species, subject to weed and pest control, maintained in a green color (e.g., by watering), and are regularly mowed to ensure an acceptable length. Lawns are used around houses, apartments, commercial buildings and offices. Many city parks also have large lawn areas. In recreational contexts, the specialised names turf, pitch, field or green may be used, depending on the sport and the continent. The term "lawn", referring to a managed grass space, dates to at least than the 16th century. With suburban expansion, the lawn has become culturally ingrained in some areas of the world as part of the desired household aesthetic.Robbins, PaulLawn People: How Grasses, Weeds, and Chemicals Make Us Who We Are P ...
