Deschampsia Antarctica
''Deschampsia antarctica'', the Antarctic hair grass, is one of two flowering plants native to Antarctica, the other being '' Colobanthus quitensis'' (Antarctic pearlwort). Ecology ''Deschampsia antarctica'' mainly occurs on the South Orkney Islands, the South Shetland Islands, and along the western Antarctic Peninsula. ''Deschampsia antartica'' distribution largely depends on the area's nutrient supply of the soil and its water distribution. ''Deschampsia antarctica'' has been recorded by the Guinness Book of World Records as the southernmost flowering plant. In 1981, a specimen was found on the Antarctic Peninsula's Refuge Islands at a latitude of 68°21′S. Since 2009, both ''D.'' ''antarctica'' and ''C. quitensis'' have been spreading rapidly, which studies suggest has been the result of rising air temperatures and a reduction in the number of fur seals. In Antarctica, the plant can be found forming low clumps in wet, protected habitats. See also * Antarctic flora Refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Poaceae
Poaceae ( ), also called Gramineae ( ), is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos, the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, including staple foods from domesticated cereal crops such as maize, wheat, rice, oats, barley, and millet for people and as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials ( bamboo, thatch, and straw); oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antler Moth
''Cerapteryx graminis'', the antler moth, is a moth of the family Noctuidae. It is a common species throughout most of Europe but is lacking in the very dry southern regions. The northernmost occurrence is Iceland, and above the Arctic Circle. It also occurs in Siberia and in North Mongolia. The species has been introduced to North America. In the Alps it rises to an altitude of 2100 meters. Description This species is unusual for a noctuid in that there is marked sexual dimorphism. The male has a wingspan of 27–32 mm but the female is much larger with a wingspan of 35–39 mm. The forewings are brown, speckled with black and marked with a bold white branched basal streak which gives the species its common name. The hindwings are dark brown with a white fringe. Technical description and variation Forewing olive grey or olive rufous, or olive fuscous; median and marginal areas sometimes deeper coloured, otherwise the 3 lines are undefined; stigmata pale, especially t ...

Clay (moth)
''Mythimna ferrago'', the clay, is a moth of the family Noctuidae. The species was first described by Johan Christian Fabricius in 1787. It is distributed throughout Europe and is also found in Morocco, Algeria, Turkey, Asia Minor, Armenia, Syria, Turkestan, Israel, Lebanon, Iraq, Iran, Central Asia and the western parts of temperate North Asia. Also Tibet. The forewings of this species vary from buffish to orangey brown, usually with a darker central line running longways down the wing, interrupted by a pale stigma. There are usually a few small dark spots in the basal area. The hindwings are dark grey with paler margins. The male is easily recognizable by a triangular area of black hair on the underside of the abdomen. The wingspan is 36–44 mm. This moth flies at night in July and August and is attracted to light and sugar. Technical description and variation The wingspan is 36–44 mm. Forewing pale greyish rufous, speckled with dark; lines indistinct, dark gr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clouded-bordered Brindle
''Apamea crenata'', known as the clouded-bordered brindle, is a moth in the family Noctuidae. It is distributed throughout the Palearctic realm. In the North it crosses the Arctic Circle, in the Mediterranean it is found only in cool locations and mountains avoiding very hot areas. In the Alps, it rises to an altitude of about 2000 metres. Description This species has a wingspan of 36 to 44 mm. The forewings are pale brown with darker patches along the margins, usually with prominent markings at the base and tornus. The hindwings are grayish with darker venation. Melanic forms occur fairly frequently. Technical description and variation Forewing pale lilac grey, often washed with pale brownish; the veins paler: costal area tinged with purplish grey; inner margin with white, and with a strong black streak near base: inner and outer lines double, brownish, the outer followed by a double row of dark brown vein dots with a white dot between; claviform stigma brown, with darker ...

Common Wainscot
''Mythimna pallens'', the common wainscot, is a moth of the family Noctuidae distributed throughout the Palearctic realm from Ireland in the west, through Europe (all of Russia) to Central Asia and Amur to the Kuriles in the east. The species was first described by Carl Linnaeus in his 1758 10th edition of ''Systema Naturae''. As with other "wainscots", this species has buffish-yellow forewings with prominent venation.
