Satyrini
The Satyrini is one of the tribes of the subfamily Satyrinae. It includes about 2200 species and is therefore the largest tribe in the subfamily which comprises 2500 species. Distribution Satyrini butterflies have a worldwide distribution, but the distribution pattern differs between subtribes. Some subtribes are almost restricted to a single biogeographic region, such as the Pronophilina, which is found only in Andean cloud forests from Venezuela to Bolivia. Biology The larval food plants of many species in this tribe are grasses, i.e. Poaceae. It is considered that the Satyrini diversified at about the same time as the grasses did, and that the radiation of the tribe is therefore closely related to the evolution of the grasses. In contrast, the tribe has a few genera which show uncommon feeding preferences. Three genera, '' Euptychia'', ''Ragadia'' and ''Acrophtalmia'', feed on Lycopsida, and moreover, some species of ''Euptychia'' have been reported to feed on mosses o ...

Wingspan
The wingspan (or just span) of a bird or an airplane is the distance from one wingtip to the other wingtip. For example, the Boeing 777–200 has a wingspan of , and a wandering albatross (''Diomedea exulans'') caught in 1965 had a wingspan of , the official record for a living bird. The term wingspan, more technically extent, is also used for other winged animals such as pterosaurs, bats, insects, etc., and other aircraft such as ornithopters. In humans, the term wingspan also refers to the arm span, which is distance between the length from one end of an individual's arms (measured at the fingertips) to the other when raised parallel to the ground at shoulder height at a 90º angle. Former professional basketball player Manute Bol stood at and owned one of the largest wingspans at . Wingspan of aircraft The wingspan of an aircraft is always measured in a straight line, from wingtip to wingtip, independently of wing shape or sweep. Implications for aircraft design and anima ...

Dactylis
''Dactylis'' is a genus of Eurasian and North African plants in the bluegrass subfamily within the grass family. ''Dactylis'' is native to North Africa, they are found throughout the world, and are an invasive species. They are known in English as cock's-foot or cocksfoot grasses, also sometimes as orchard grasses. Taxonomy The genus has been treated as containing only a single species ''Dactylis glomerata'' by many authors, treating variation in the genus at only subspecific rank within ''D. glomerata'',Flora Europaea''Dactylis glomerata''Flora of China Town''Dactylis''/ref> but more recently, there has been a trend to accept two species,Germplasm Resources Information NetworkSpecies Records of ''Dactylis'' while some authors accept even more species in the genus, particularly island endemic species in Macaronesia.Schönfelder, P., & Ludwig, D.

Cynosurus Cristatus
''Cynosurus cristatus'', the crested dog's-tail, is a short-lived perennial grass in the family Poaceae, characterised by a seed head that is flat on one side. It typically grows in species rich grassland. It thrives in a variety of soil types but avoids the acid and calcareous extremes of pH, and prefers well drained soils. retrieved 10 December 2010.

Brachypodium Pinnatum
''Brachypodium pinnatum'', the heath false brome or tor-grass, is a species of grass with a widespread distribution in temperate regions of the Northern Hemisphere. It typically grows in calcareous grassland, and reaches tall. The flowerhead is open, with 10 to 15 erect spikelets. Distribution The plant can be found in such US states as California, Massachusetts, and Oregon. Ecology The caterpillars of some Lepidoptera use it as a food plant, e.g. the Essex skipper (''Thymelicus lineola''). It is also one of the most important host grasses for Auchenorrhyncha in central Europe.Nickel, H. (2003).

Bromus Erectus
''Bromus erectus'', commonly known as erect brome, upright brome or meadow brome, is a dense, course, tufted perennial grass. It can grow to . Like many brome grasses the plant is hairy. The specific epithet ''erectus'' is Latin, meaning "erect". The diploid number of the grass is 56. Description ''Bromus erectus'' is a perennial, tufted grass with basal tufts of cespitose leaves that is nonrhizomatous. The culms grow between in height. The internodes are typically glabrous. The flattened cauline leaves have pubescent or glabrous sheaths. The leaf blades are long and wide. The grass lacks auricles and the ligule is blunt but finely serrated, sometimes with hairy edges. The contracted and ellipsoid panicle is usually upright, rather than nodding, measuring long. The lanceolate spikelets are long and have five to twelve flowers.

Festuca
''Festuca'' (fescue) is a genus of flowering plants belonging to the grass family Poaceae (subfamily Pooideae). They are evergreen or herbaceous perennial tufted grasses with a height range of and a cosmopolitan distribution, occurring on every continent except Antarctica. The genus is closely related to ryegrass (''Lolium''), and recent evidence from phylogenetic studies using DNA sequencing of plant mitochondrial DNA shows that the genus lacks monophyly. As a result, plant taxonomists have moved several species, including the forage grasses tall fescue and meadow fescue, from the genus ''Festuca'' into the genus ''Lolium'', or alternatively into the segregate genus ''Schedonorus''. Because the taxonomy is complex, scientists have not determined how many true species belong to the genus, but estimates range from more than 400 to over 640.Darbyshire, S. J. and L. E.

Univoltine
Voltinism is a term used in biology to indicate the number of broods or generations of an organism in a year. The term is most often applied to insects, and is particularly in use in sericulture, where silkworm varieties vary in their voltinism. * Univoltine (monovoltine) – (adjective) referring to organisms having one brood or generation per year * Bivoltine (divoltine) – (adjective) referring to organisms having two broods or generations per year *Trivoltine – (adjective) referring to organisms having three broods or generations per year * Multivoltine (polyvoltine) – (adjective) referring to organisms having more than two broods or generations per year * Semivoltine – There are two meanings: :* (''biology'') Less than univoltine; having a brood or generation less often than once per year :* or (adjective) referring to organisms whose generation time is more than one year. Examples The speckled wood butterfly is univoltine in the northern part of its range, e.g. north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Siberia
Siberia ( ; rus, Сибирь, r=Sibir', p=sʲɪˈbʲirʲ, a=Ru-Сибирь.ogg) is an extensive geographical region, constituting all of North Asia, from the Ural Mountains in the west to the Pacific Ocean in the east. It has been a part of Russia since the latter half of the 16th century, after the Russians conquered lands east of the Ural Mountains. Siberia is vast and sparsely populated, covering an area of over , but home to merely one-fifth of Russia's population. Novosibirsk, Krasnoyarsk and Omsk are the largest cities in the region. Because Siberia is a geographic and historic region and not a political entity, there is no single precise definition of its territorial borders. Traditionally, Siberia extends eastwards from the Ural Mountains to the Pacific Ocean, and includes most of the drainage basin of the Arctic Ocean. The river Yenisey divides Siberia into two parts, Western and Eastern. Siberia stretches southwards from the Arctic Ocean to the hills of north-ce ...
