Deschampsia Flexuosa
''Deschampsia flexuosa'', commonly known as wavy hair-grass, is a species of bunchgrass in the grass family widely distributed in Eurasia, Africa, South America, and North America. Description Wavy hair-grass, ''Deschampsia flexuosa'', has wiry leaves and delicate, shaking panicles formed of silvery or purplish-brown flower heads on wavy, hair-like stalks. The leaves are bunched in tight tufts with plants forming a very tussocky, low sward 5 to 20 cm tall before flowering, to 30 cm high. File:Deschampsia flexuosa.jpg, Illustration of ''D. flexuosa'' (including '' D. caespitosa'') File:Avenella flexuosa.jpg, Mature inflorescence Distribution and habitat ''Deschampsia flexuosa'' is found naturally in dry grasslands and on moors and heaths. It is also an important component of the ground flora of birch and oak woodland. The plant has a preference for acidic, free-draining soil, and avoids chalk and limestone areas. It can exist over above sea level. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deschampsia Cespitosa
''Deschampsia cespitosa'', commonly known as tufted hairgrass or tussock grass, is a perennial tufted plant in the grass family Poaceae. Distribution of this species is widespread including the eastern and western coasts of North America, parts of South America, Eurasia and Australia.

Deschampsia Antarctica
''Deschampsia antarctica'', the Antarctic hair grass, is one of two flowering plants native to Antarctica, the other being ''Colobanthus quitensis'' (Antarctic pearlwort). They mainly occur on the South Orkney Islands, the South Shetland Islands, and along the western Antarctic Peninsula. A recent warming trend has increased germination, and thus number of seedlings and plants, also extending their range southward to cover larger areas; reports indicate a twenty-fivefold increase in their number. ''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 seal, fur seals.

Poaceae
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and 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, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well 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); others can provide a source of biofuel, ...

Dusky Brocade
''Apamea remissa'', the dusky brocade, is a species of moth of the family Noctuidae. It is distributed throughout Europe and Turkey, ranging across the Palearctic realm to Siberia, Manchuria and Japan. It has also been reported from Alaska.Kononenko, V. S., et al. (1989). Annotated list of owlet moths (Lepidoptera, Noctuidae) of Beringia. ''Entomologicheskoe Obozrenie'' 68(3) 549-67. Some authors consider '' Apamea indocilis'' to be a subspecies of ''Apamea remissa''. Description This species has a wingspan of 36 to 42 mm. Well-marked individuals are fairly distinctive, but forms with obscure markings can be difficult to distinguish from other species. The typical form has pale greyish-brown forewings with dark markings, including a large blackish mark near the dorsum and two spots at the termen. The difference between the ground colour and the dark shading is pronounced, the ground being pale grey, often reddish tinted, and the markings blackish fuscous;some black wedge s ...

Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern 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 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 measured temperature on Earth, . The coastal regions can reach temperatures over in summer. Native species of animals include mites, nematodes, penguins, seals and tardigrades. Where vegetation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Portlethen Moss
The Portlethen Moss is an acidic bog nature reserve located to the west of the town of Portlethen, Aberdeenshire in Scotland. Like other Bog, mosses, this wetland area supports a variety of plant and animal species, even though it has been subject to certain development and agricultural degradation pressures. For example, the Great Crested Newt was found here prior to the expansion of the town of Portlethen. Many acid loving vegetative species occur in Portlethen Moss, and the habitat is monitored by the Scottish Wildlife Trust. Portlethen Moss is the location of considerable prehistoric, Middle Ages and seventeenth century history, largely due to a ridge near the bog which was the route of early travellers. By at least the Middle Ages this trackway was more formally constructed with raised stonework and called the Causey Mounth. Without this drovers' road, travel through the Portlethen Moss and several nearby bogs would have been impossible between Aberdeen and coastal points to ...
