Poa Trivialis
''Poa trivialis'' (rough bluegrass; ''UK:'' rough-stalked meadow-grass or rough meadow-grass), is a perennial plant regarded in the US as an ornamental plant. It is part of the Poaceae, grass family. Description It is very common in meadows and pastures throughout United Kingdom, Britain. Its preferred habitat is moist, sheltered places. Its wiktionary:herbage, herbage is plentiful and fairly nutritious, though not as much as ''Poa annua'' or ''Poa pratensis''. It is useful for grazing on heavy and damp soil. It also copes well with the polluted atmosphere of towns and cities. It is in flower from June onwards throughout the summer. It is often considered a weed of golf courses. It is an invasive species in the Great Lakes region and was first sighted in 1843. It has short stolons. The leaves are broad and tapering, and the sheathes are very rough. It has shiny leaves like ''Lolium perenne'' and crested dog's-tail. They have pointed ligules 4–10 mm (3/16 – 3/8 in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carl Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ligule
A ligule (from "strap", variant of ''lingula'', from ''lingua'' "tongue") is a thin outgrowth at the junction of leaf and leafstalk of many grasses (Poaceae) and sedges. A ligule is also a strap-shaped extension of the corolla, such as that of a ray floret in plants in the daisy family Asteraceae. Poaceae and Cyperaceae The ligule is part of the leaf that is found at the junction of the blade and sheath of the leaf. It may take several forms, but it is commonly some form of translucent membrane or a fringe of hairs. The membranous ligule can be very short 1–2 mm (Kentucky bluegrass, ''Poa pratensis'') to very long 10–20 mm (Johnson grass, ''Sorghum halepense''), it can also be smooth on the edge or very ragged. Some grasses do not have a ligule, for example barnyardgrass (''Echinochloa crus-galli''). A ligule can also be defined as a membrane-like tissue or row of delicate hairs typically found in grasses at the junction of the leaf sheath and blade. The ...

Blumeria Graminis
''Blumeria graminis'' (commonly called barley powdery mildew or corn mildew) is a fungus that causes powdery mildew on grasses, including cereals. It is the only species in the genus ''Blumeria''. It has also been called ''Erysiphe graminis'' and (by its anamorph) ''Oidium monilioides'' or ''Oidium tritici''. Systematics Previously ''B. graminis'' was included within the genus ''Erysiphe'', but molecular studies have placed it into a clade of its own. Thus since 1975, the species ''graminis'' was moved into the new taxa ''Blumeria'' of which it is the only species. ''Blumeria'' differs from ''Erysiphe'' in its digitate haustoria and in details of the conidial wall. As well ''Blumeria'' is considered to be phylogenetically distinct from ''Erisiphe'' as it is a plant pathogen that hosts solely on the true grasses of ''Poaceae. '' Eight special forms or ''formae speciales'' (ff.spp.) of ''B. graminis'' have been distinguished, each of which is parasitic on a particular genus of gras ...

Leafhopper
A leafhopper is the common name for any species from the family Cicadellidae. These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species. They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhyncha, but as the latter taxon is probably not monophyletic, many modern au ...

Amara Aenea
''Amara aenea'' is a ground beetle common in almost the whole of Europe and Northern Asia. Its range covers also parts of Northern Africa. It is known as the common sun beetle. ''A. aenea'' adults are predators that eat other insects, such as the apple maggot and Aphis glycines, soybean aphid, which are considered pests by the Agribusiness, agriculture industry. As such, this beetle is under study for use in integrated pest management. Larvae are omnivorous. The adults feed on the developing seed of ''Poa trivialis'' and smooth meadow grass ''Poa pratensis''.

Gatekeeper Butterfly
The gatekeeper or hedge brown (''Pyronia tithonus'') is a European species of butterfly. Given its preference for warmer weather, the restriction of range expansion can be assumed to be due to climate. Colonies vary in size depending on the available habitat, and can range from a few dozen to several thousand butterflies. Similar species and subspecies It is a member of the subfamily Satyrinae in the family Nymphalidae. A similar species is the meadow brown; the two species can be difficult to distinguish with closed wings, since the underwing markings are very similar. However, the gatekeeper tends to rest with its wings open, whereas the meadow brown usually rests with its wings closed. The gatekeeper is also smaller and more orange than the meadow brown and has double pupils on its eyespots. Two other similar species of ''Pyronia'' are found in southern Europe, the southern gatekeeper ('' P. cecilia'') and the Spanish gatekeeper ('' P. bathsheba''). ''P. tithon ...

Meadow Brown
The meadow brown (''Maniola jurtina'') is a butterfly found in the Palearctic realm. Its range includes Europe south of 62°N, Russia eastwards to the Urals, Asia Minor, Iraq, Iran, North Africa and the Canary Islands. The larvae feed on grasses. Description There is marked sexual dimorphism in this species. The upperside of the male is uniformly light brown with a black ocellus centered white at the apex of the forewing, while the female has a tawny patch more or less extended around this ocella. The underside forewing is ochre-colored bordered with dark beige with the same ocelli at the apex in the male, while the hindwing is greyish to brown with a more or less orange band in the female. The males are also much more active and range far about, while females fly less and often may not move away from the area where they grew up. Description in Seitz Above dark brown: the apical ocellus minutely centred with white, being in the male bordered with dull dark yellow, and standing ...

Coenonympha Pamphilus
The small heath (''Coenonympha pamphilus'') is a butterfly species belonging to the family Nymphalidae, classified within the subfamily Satyrinae (commonly known as "the browns"). It is the smallest butterfly in this subfamily. The small heath is diurnal and flies with a noticeable fluttering flight pattern near the ground. It rests with closed wings when not in flight.Wickman, Per-Clof. "The Influence of Temperature on the Territorial and Mate Locating Behaviour of the Small Heath Butterfly, Coenonympha Pamphilus (L.) (Lepidoptera: Satyridae)." ''Behavioral Ecology and Sociobiology'', vol. 16, no. 3, 1985, pp. 233–238., doi:10.1007/bf00310985. It is widespread in colonies throughout the grasslands of Eurasia and north-western Africa, preferring drier habitats than other ''Coenonympha'', such as salt marshes, alpine meadows, wetlands, and grasslands near water (i.e. streams). However, habitat loss caused by human activities has led to a decline in populations in some locati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salisbury Plain
Salisbury Plain is a chalk plateau in the south western part of central southern England covering . It is part of a system of chalk downlands throughout eastern and southern England formed by the rocks of the Chalk Group and largely lies within the county of Wiltshire, but stretches into Hampshire. The plain is famous for its rich archaeology, including Stonehenge, one of England's best known landmarks. Large areas are given over to military training and thus the sparsely populated plain is the biggest remaining area of calcareous grassland in northwest Europe. Additionally the plain has arable land, and a few small areas of beech trees and coniferous woodland. Its highest point is Easton Hill. Physical geography The boundaries of Salisbury Plain have never been truly defined, and there is some difference of opinion as to its exact area. The river valleys surrounding it, and other downs and plains beyond them loosely define its boundaries. To the north the scarp of the ...
