Bluegrass (grass)
''Poa'' is a genus of about 570 species of Poaceae, grasses, native to the temperate regions of both hemispheres. Common names include meadow-grass (mainly in Europe and Asia), bluegrass (mainly in North America), tussock (some New Zealand species), and speargrass. ''Poa'' () is Greek language, Greek for "fodder". ''Poa'' are members of the subfamily Pooideae of the family Poaceae. Bluegrass, which has green leaves, derives its name from the seed heads, which are blue when the plant is allowed to grow to its natural height of two to three feet (0.6 to 0.9 meters). The genus ''Poa'' includes both annual plant, annual and perennial plant, perennial species. Most are plant sexuality, monoecious, but a few are plant sexuality, dioecious (separate male and female plants). The leaf, leaves are narrow, folded or flat, sometimes bristled, and with the basal sheath flattened or sometimes thickened, with a blunt or hooded apex and membranaceous ligule.

Poa Annua
''Poa annua'', or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Notwithstanding the reference to annual plant in its name, perennial bio-types do exist. This grass may have originated as a hybrid between ''Poa supina'' and '' Poa infirma''. Description It has a slightly creeping, fibrous, rootstock. The stem grows from 15–25 cm (6-10 in.) high. It is slightly flattened, due to being folded rather than rolled. The panicle is open and triangular shaped, 5 to 7.5 cm (2 to 3 in.) long. The spikelets are stalked, awnless, 1 to 2 cm (3/8 to 3/4 in.) long when flowering, and loosely arranged on delicate paired or spreading branches. Sometimes they are tinged purple. The vivid green leaves are short and blunt at the tips, shaped like the prow of a small canoe. They are soft and drooping. Long sheaths clasp the stem. The leaves are smooth above and below, with fin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grazing
In agriculture, grazing is a method of animal husbandry whereby domestic livestock are allowed outdoors to roam around and consume wild vegetations in order to convert the otherwise indigestible (by human gut) cellulose within grass and other forages into meat, milk, wool and other animal products, often on land unsuitable for arable farming. Farmers may employ many different strategies of grazing for optimum production: grazing may be continuous, seasonal, or rotational within a grazing period. Longer rotations are found in ley farming, alternating arable and fodder crops; in rest rotation, deferred rotation, and mob grazing, giving grasses a longer time to recover or leaving land fallow. Patch-burn sets up a rotation of fresh grass after burning with two years of rest. Conservation grazing proposes to use grazing animals to improve the biodiversity of a site, but studies show that the greatest benefit to biodiversity comes from removing grazing animals from the landscape. ...

Cercyonis Pegala
The common wood-nymph (''Cercyonis pegala'') is a North American butterfly in the family Nymphalidae. It is also known as the wood-nymph, grayling, blue-eyed grayling, and the goggle eye. Description The common wood-nymph can vary greatly. All individuals are brown with two eyespots on each forewing – the lower one often being larger than the upper one. Some may have many, few, or no eyespots on the ventral surface of the hindwing. In the southeastern part of its range, it has a large yellow patch on both surfaces of the forewing. In the western part of its range, it may have a pale yellow patch or may be lacking one. Individuals in the Northeast also lack the yellow patch, i.e., ''C. p. nephele''. In individuals with no yellow patch, there are two pale yellow eye rings that encircle both the forewing eyespots. The wingspan measures 5.3 to 7.3 cm (2.1 to 2.9 in). These butterflies have ears on their forewings that are most sensitive to low frequency sounds (l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agriphila Inquinatella
:''The name ''Agriphila inquinatella'' has been misapplied to some related species in the past; see below for details.'' ''Agriphila inquinatella'' is a small moth species of the family Crambidae. It is found in Europe, around the Caucasus area to Turkestan, and in the Near East to Jordan. The type locality is in Austria. Three subspecies are accepted today: * ''Agriphila inquinatella inquinatella'' (Denis & Schiffermüller, 1775) – most of the range * ''Agriphila inquinatella nevadensis'' (Caradja, 1910) – Sierra Nevada and presumably elsewhere in Spain * ''Agriphila inquinatella elbursella'' (Zerny, 1939) – Alborz mountains and presumably elsewhere in the Caucasus region The adult moths fly between June and September, depending on the location. Their wingspan is 23–29 mm. The caterpillars feed mainly on Poaceae grasses, such as meadow-grass species (''Poa'') or sheep's fescue (''Festuca ovina''). They can be found under pebbles adjacent to their food ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lepidoptera
Lepidoptera ( ) is an order (biology), order of insects that includes butterfly, butterflies and moths (both are called lepidopterans). About 180,000 species of the Lepidoptera are described, in 126 Family (biology), families and 46 Taxonomic rank, superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most wikt:speciose, speciose orders, along with the Hymenoptera, fly, Diptera, and beetle, Coleoptera. Lepidopteran species are characterized by more than three derived features. The most apparent is the presence of scale (anatomy), scales that cover the torso, bodies, wings, and a proboscis. The scales are modified, flattened "hairs", and give ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nephritis
Nephritis is inflammation of the kidneys and may involve the glomeruli, tubules, or interstitial tissue surrounding the glomeruli and tubules. It is one of several different types of nephropathy. Types * Glomerulonephritis is inflammation of the glomeruli. Glomerulonephritis is often implied when using the term "nephritis" without qualification. * Interstitial nephritis (or tubulo-interstitial nephritis) is inflammation of the spaces between renal tubules. Causes Nephritis is often caused by infections, and toxins, but is most commonly caused by autoimmune disorders that affect the major organs like kidneys. * Pyelonephritis is inflammation that results from a urinary tract infection that reaches the renal pelvis of the kidney. * Lupus nephritis is inflammation of the kidney caused by systemic lupus erythematosus (SLE), a disease of the immune system. * Athletic nephritis is nephritis resulting from strenuous exercise. Bloody urine after strenuous exercise may also result from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Galen
Aelius Galenus or Claudius Galenus ( el, Κλαύδιος Γαληνός; September 129 – c. AD 216), often Anglicized as Galen () or Galen of Pergamon, was a Greek physician, surgeon and philosopher in the Roman Empire. Considered to be one of the most accomplished of all medical researchers of antiquity, Galen influenced the development of various scientific disciplines, including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy and logic. The son of Aelius Nicon, a wealthy Greek architect with scholarly interests, Galen received a comprehensive education that prepared him for a successful career as a physician and philosopher. Born in the ancient city of Pergamon (present-day Bergama, Turkey), Galen traveled extensively, exposing himself to a wide variety of medical theories and discoveries before settling in Rome, where he served prominent members of Roman society and eventually was given the position of personal physician to several emp ...

Golf Course
A golf course is the grounds on which the sport of golf is played. It consists of a series of holes, each consisting of a tee box, a fairway, the rough and other hazards, and a green with a cylindrical hole in the ground, known as a "cup". The cup holds a flagstick, known as a "pin". A standard round of golf consists of 18 holes, and as such most courses contain 18 distinct holes; however, there are many 9-hole courses and some that have holes with shared fairways or greens. There are also courses with a non-standard number of holes, such as 12 or 14. The vast majority of golf courses have holes of varying length and difficulties that are assigned a standard score, known as par, that a proficient player should be able to achieve; this is usually three, four or five strokes. Par-3 courses consist of holes all of which have a par of three. Short courses have gained in popularity; these consist of mostly par 3 holes, but often have some short par 4 holes. Many older courses ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
