William Nylander (botanist)
William (Wilhem) Nylander (3 January 1822 – 29 March 1899) was a Finnish botanist and entomologist. Nylander was born in Oulu, and taught at the University of Helsinki before moving to Paris, where he lived until his death in 1899. Nylander studied medicine, receiving a degree in 1847. Nylander pioneered the technique of determining the taxonomy of lichens by the use of chemical reagents, such as potassium hydroxide, tinctures of iodine and calcium hypochlorite, still used by lichenologists as the K and C tests. Nylander was the first to realise the effect of atmospheric pollution Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types ... on the growth of lichens, an important discovery that paved the way for the use of lichens to detect pollution and determine the cleanness o ...

Carex Acutiformis
''Carex acutiformis'', the lesser pond-sedge, is a species of sedge. Description It grows up to tall, with leaves up to long and wide.

Moths Of Europe
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Elachista
''Elachista'' is a genus of gelechioid moths described by Georg Friedrich Treitschke in 1833. It is the type genus of the grass-miner moth family (Elachistidae). This family is sometimes (in particular in older sources) circumscribed very loosely, including for example the Agonoxenidae and Ethmiidae which seem to be quite distinct among the Gelechioidea, as well as other lineages which are widely held to be closer to ''Oecophora'' than to ''Elachista'' and are thus placed in the concealer moth family Oecophoridae here. These grass-miners are very small moths with the "feathery" hindwings characteristic of their family. They are essentially found worldwide, except in very cold places and on some oceanic islands; as usual for Gelechioidea, they are most common in the Palearctic however. They usually have at least one, sometimes as many as three light bands running from leading to trailing edge of their forewing uppersides. Some species, however, have upper forewings that are mo ...

Eriophorum Angustifolium
''Eriophorum angustifolium'', commonly known as common cottongrass or common cottonsedge, is a species of flowering plant in the sedge family, Cyperaceae. Native to North America, North Asia, and Northern Europe, it grows on peat or acidic soils, in open wetland, heath or moorland. It begins to flower in April or May and, after fertilisation in early summer, the small, unremarkable brown and green flowers develop distinctive white bristle-like seed-heads that resemble tufts of cotton; combined with its ecological suitability to bog, these characteristics give rise to the plant's alternative name, bog cotton. ''Eriophorum angustifolium'' is a hardy, herbaceous, rhizomatous, perennial sedge, able to endure in a variety of environments in the temperate, subarctic and arctic regions of Earth. Unlike ''Gossypium'', the genus from which cotton is derived, the bristles which grow on ''E. angustifolium'' are unsuited to textile manufacturing. Nevertheless, in Northern Europe, they ...

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. The species is cultivated as an ornamental garden plant, and numerous cultivars are available. The cultivars 'Goldschleier' and 'Goldtau' have gained the Royal Horticultural Society's Award of Garden Merit. It is a larval host to the Juba skipper and the umber skipper.
