Andreaea depressinervis | |
Andreaea depressinervis is a species of moss in the family Andreaeaceae that was discovered by Jules Cardot in 1901. [2] It is found on both the South Shetland Islands and the Antarctica. [3]
Andreaea depressinervis has costate leaves, which means they have parallel veins throughout the leaves. [2]
Deception Island is an island in the South Shetland Islands close to the Antarctic Peninsula with a large and usually "safe" natural harbor, which is occasionally troubled by the underlying active volcano. This island is the caldera of an active volcano, which seriously damaged local scientific stations in 1967 and 1969. The island previously held a whaling station. It is now a tourist destination with over 15,000 visitors per year. Two research stations are operated by Argentina and Spain during the summer season. While various countries have asserted sovereignty, it is still administered under the Antarctic Treaty System.
The South Shetland Islands are a group of Antarctic islands with a total area of 3,687 km2 (1,424 sq mi). They lie about 120 kilometres north of the Antarctic Peninsula, and between 430 and 900 km southwest of the nearest point of the South Orkney Islands. By the Antarctic Treaty of 1959, the islands' sovereignty is neither recognized nor disputed by the signatories and they are free for use by any signatory for non-military purposes.
King George Island is the largest of the South Shetland Islands, lying 120 km off the coast of Antarctica in the Southern Ocean. The island was named after King George III.
Livingston Island is an Antarctic island in the Southern Ocean, part of the South Shetlands Archipelago, a group of Antarctic islands north of the Antarctic Peninsula. It was the first land discovered south of 60° south latitude in 1819, a historic event that marked the end of a centuries-long pursuit of the mythical Terra Australis Incognita and the beginning of the exploration and utilization of real Antarctica. The name Livingston, although of unknown derivation, has been well established in international usage since the early 1820s.
Half Moon Island is a minor Antarctic island, lying in McFarlane Strait 1.35 km (0.84 mi) north of Burgas Peninsula, Livingston Island in the South Shetland Islands of the Antarctic Peninsula region. Its surface area is 171 hectares. The Argentine Cámara Base is located on the island. It is only accessible by sea and by helicopter; there is no airport of any kind. The naval base is operational occasionally during the summer, but is closed during the winter.
Cockburn Island is an oval island 2.7 kilometres (1.7 mi) long, consisting of a high plateau with steep slopes surmounted on the northwest side by a pyramidal peak 450 m (1,476 ft) high, lying in the north-east entrance to Admiralty Sound, south of the north-east end of the Antarctic Peninsula. It was discovered by a British expedition (1839–43) led by Captain James Clark Ross, who named it for Admiral Sir George Cockburn, then serving as First Naval Lord.
The Aitcho Islands are a group of minor islands on the west side of the north entrance to English Strait separating Greenwich Island and Robert Island in the South Shetland Islands, Antarctica, which are situated between Dee Island to the south and Table Island to the north. The group is separated from Dee Island and Sierra Island to the southwest by Villalón Passage. The area was visited by early 19th century sealers operating from nearby Clothier Harbour. During the austral summer the islands are often visited by Antarctic cruise ships with tourists who land to watch wildlife.
Yankee Harbour is a small inner harbour entered from Shopski Cove between Glacier Bluff and Spit Point, indenting the south-west side of Greenwich Island in the South Shetland Islands, Antarctica. It is 2.35 km (1.46 mi) long in west-south-west to east-north-east direction, and 1.6 km (0.99 mi) wide, and is bounded by Provadiya Hook to the south-west, Parvomay Neck to the north and east, and Kladara Beach to the south.
Andreaea gainii is a species of moss native to western Antarctica and the South Shetland Islands. It grows on exposed rocks and soil.
Andreaea regularis is a species of moss that grows in Antarctica and on the South Shetland Islands.
Dicranoweisia brevipes is a species of moss that occurs on the Antarctic Peninsula and regional islands.
Dicranoweisia crispula, the mountain pincushion, is a species of mosses that lives at both poles. It grows in the South Shetland Islands and on the Antarctic Peninsula.
Didymodon gelidus is a species of mosses that grows in Antarctica and on the South Shetland Islands.
Coppermine Peninsula is the rugged, rocky promontory forming the northwest extremity of Alfatar Peninsula and Robert Island in the South Shetland Islands, Antarctica. It lies between the English Strait to the west and Carlota Cove to the east. It is 1.7 km long, 500 m wide and rising to 105 m.
Andreaea Plateau is a small plateau with an average elevation of 180 metres (590 ft), located southwest of Robin Peak, Signy Island, in the South Orkney Islands. The feature is notable for the largest known stand in the Antarctic of the black-brown moss Andreaea.
Moe Island is an island 2 km (1.2 mi) long in the South Orkney Islands off Antarctica, separated from the south-west end of Signy Island by Fyr Channel. It was charted by Captain Petter Sørlle in 1912–13, and named after M. Thoralf Moe of Sandefjord, Norway, a contemporary whaling captain who worked in this area. The northernmost point of the island is Spaull Point, named by United Kingdom Antarctic Place-Names Committee (UK-APC) after Vaughan W. Spaull, British Antarctic Survey (BAS) biologist on Signy Island, 1969.
Hennediella heimii, also known as Heim's pottia, is a moss with 2.5 mm brown or yellow-green tufts.
Andreaea rothii, or Roth's andreaea moss, is a species of moss in the family Andreaeaceae native to North America and parts of Europe. This plant was described in 1807 by Weber and Mohr.
Polytrichum piliferum, the bristly haircap, is an evergreen perennial species of moss in the family Polytrichaceae. The bristly haircap moss is small-sized to medium-sized and forms loose tufts with wine-reddish stems. It is an acrocarpous moss that appears bluish-green to grey. This moss grows in clumps on erect shoots and becomes a red-brown colour as it grows older. The most distinguishing feature of P. piliferum is the long, white awn at the tips of the leaves, which also give this moss its grey colour. It is the only species in its genus where the awn is completely hyaline.
