Salticus Cingulatus
''Salticus cingulatus'' is a Palearctic jumping spider of the family Salticidae. Description The female ''Salticus cingulatus'' has a body length of 5.2–5.5 mm while the male's is 3.4–6 mm. On the male the palpal bulb is distally forked, with a long visible part. On the female the epigyne is strongly sclerotized, the anterior part opaque. The prosoma is black, with white spots, and the opisthosoma is black, but largely covered with white hairs. It is similar to ''Salticus scenicus'' but it is normally distinguished by being much paler due to more white hairs on the prosoma. Habitat and ecology The favoured habitat of ''Salticus cingulatus'' is old tree trunks and fence palings situated in sunny situations in or close to woodland, fens and heathland. It is frequently encountered on pines A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae.

Georg Wolfgang Franz Panzer
Georg Wolfgang Franz Panzer (31 May 1755 – 28 June 1829) was a German botanist and entomologist. He was born at Etzelwang in the Upper Palatinate and died at Hersbruck, near Nuremberg. He was the son of (the elder, 1729-1805), one of the most distinguished and productive of German bibliographers, whose ''Annales Typographici'' were published between 1793 and 1803.G.W. Panzer, ''Annales Typographici ab Artis Inventae Origine usque ad annum MDXXXVI'', 11 Vols (Impensis Joannis Eberhardi Zeh, Bibliopolae, Norimbergae 1793-1803). A physician, he practised at Hersbruck. A celebrated botanist, he had a very species-rich herbarium. He also assembled a very important insect collection which was the basis of a vast work ''Faunae insectorum germanicae initia'' (Elements of the insect fauna of Germany), published at Nuremberg between 1796 and 1813. Illustrated by Jacob Sturm Jacob Sturm (21 March 1771 – 28 November 1848) was a leading engraver of entomological and botanical ...

Woodland
A woodland () is, in the broad sense, land covered with trees, or in a narrow sense, synonymous with wood (or in the U.S., the ''plurale tantum'' woods), a low-density forest forming open habitats with plenty of sunlight and limited shade (see differences between British, American, and Australian English explained below). Woodlands may support an understory of shrubs and herbaceous plants including grasses. Woodland may form a transition to shrubland under drier conditions or during early stages of primary or secondary succession. Higher-density areas of trees with a largely closed canopy that provides extensive and nearly continuous shade are often referred to as forests. Extensive efforts by conservationist groups have been made to preserve woodlands from urbanization and agriculture. For example, the woodlands of Northwest Indiana have been preserved as part of the Indiana Dunes. Definitions United Kingdom ''Woodland'' is used in British woodland management to mean tre ...

Great Britain
Great Britain is an island in the North Atlantic Ocean off the northwest coast of continental Europe. With an area of , it is the largest of the British Isles, the largest European island and the ninth-largest island in the world. It is dominated by a maritime climate with narrow temperature differences between seasons. The 60% smaller island of Ireland is to the west—these islands, along with over 1,000 smaller surrounding islands and named substantial rocks, form the British Isles archipelago. Connected to mainland Europe until 9,000 years ago by a landbridge now known as Doggerland, Great Britain has been inhabited by modern humans for around 30,000 years. In 2011, it had a population of about , making it the world's third-most-populous island after Java in Indonesia and Honshu in Japan. The term "Great Britain" is often used to refer to England, Scotland and Wales, including their component adjoining islands. Great Britain and Northern Ireland now constitute the ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

British Arachnological Society
The British Arachnological Society (BAS) is the UK’s first body devoted exclusively to the study of arachnids. The primary objectives of the Society are to encourage interest in arachnology in people of all ages and to generate, promote and disseminate arachnological knowledge and understanding by all suitable means. In particular, it works to foster co-operation between amateur and professional arachnologists. Actively involved in scientific aspects of arachnid conservation, it provides impartial information and expert advice on the ecology and biology of British arachnids to policy and decision makers in Government and non-governmental organisations (NGOs), as well as to conservation practitioners, private interests and the public. The Society oversees national recording schemes for spiders, harvestmen and pseudoscorpions. Founded in 1958, it is one of the oldest societies specializing in this animal group, publishing a journal (''Arachnology'') and a Newsletter three times ...

Pinus
A pine is any conifer tree or shrub in the genus ''Pinus'' () of the family Pinaceae. ''Pinus'' is the sole genus in the subfamily Pinoideae. The World Flora Online created by the Royal Botanic Gardens, Kew and Missouri Botanical Garden accepts 187 species names of pines as current, together with more synonyms. The American Conifer Society (ACS) and the Royal Horticultural Society accept 121 species. Pines are commonly found in the Northern Hemisphere. ''Pine'' may also refer to the lumber derived from pine trees; it is one of the more extensively used types of lumber. The pine family is the largest conifer family and there are currently 818 named cultivars (or trinomials) recognized by the ACS. Description Pine trees are evergreen, coniferous resinous trees (or, rarely, shrubs) growing tall, with the majority of species reaching tall. The smallest are Siberian dwarf pine and Potosi pinyon, and the tallest is an tall ponderosa pine located in southern Oregon's Rogue Riv ...

Heathland
A heath () is a shrubland habitat found mainly on free-draining infertile, acidic soils and characterised by open, low-growing woody vegetation. Moorland is generally related to high-ground heaths with—especially in Great Britain—a cooler and damper climate. Heaths are widespread worldwide but are fast disappearing and considered a rare habitat in Europe. They form extensive and highly diverse communities across Australia in humid and sub-humid areas where fire regimes with recurring burning are required for the maintenance of the heathlands.Specht, R.L. 'Heathlands' in 'Australian Vegetation' R.H. Groves ed. Cambridge University Press 1988 Even more diverse though less widespread heath communities occur in Southern Africa. Extensive heath communities can also be found in the Texas chaparral, New Caledonia, central Chile, and along the shores of the Mediterranean Sea. In addition to these extensive heath areas, the vegetation type is also found in scattered locations acro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salticus Scenicus
The zebra jumping spider (''Salticus scenicus'') is a common jumping spider of the Northern Hemisphere. Their common name refers to their vivid black-and-white colouration, whilst their scientific name derives from ''Salticus'' from the Latin for “dancing”, in reference to their agility, and the Greek ''scenicus'', translating to “theatrical” or “of a decorative place,” in reference to the flashy, zebra-like coloration of the species. Description Female zebra spiders are 5–9 mm long, while males are 5–6 mm. Male zebra spiders have distinctly larger chelicerae than females. Spiders in the family Salticidae have especially enlarged anterior median eyes (AME), though the anterior and posterior lateral eyes (ALE, PLE) are also large when compared to the very small posterior median eyes (PME). In total there are eight eyes, with the very large anterior median eyes primarily responsible for its excellent binocular vision. These small spiders are black with whi ...

Palearctic
The Palearctic or Palaearctic is the largest of the eight biogeographic realms of the Earth. It stretches across all of Eurasia north of the foothills of the Himalayas, and North Africa. The realm consists of several bioregions: the Euro-Siberian region; the Mediterranean Basin; the Sahara and Arabian Deserts; and Western, Central and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions. The term 'Palearctic' was first used in the 19th century, and is still in use as the basis for zoogeographic classification. History In an 1858 paper for the ''Proceedings of the Linnean Society'', British zoologist Philip Sclater first identified six terrestrial zoogeographic realms of the world: Palaearctic, Aethiopian/Afrotropic, Indian/Indomalayan, Australasian, Nearctic, and Neotropical. The six indicated general groupings of fauna, based on shared biogeography and large-scale geographic barriers to migration. Alfred Wallace a ...

Opisthosoma
The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma (cephalothorax). It is a distinctive feature of the subphylum Chelicerata (arachnids, horseshoe crabs and others). Although it is similar in most respects to an abdomen (and is often referred to as such), the opisthosoma is differentiated by its inclusion of the respiratory organs (book lungs or book gills) and the heart. Segments The number of segments and appendages on the opisthosoma vary. Scorpions have 13, but the first is only seen during its embryological development. Other arachnids have fewer; harvestmen, for instance, have only ten. In general, appendages are absent or reduced, although in horseshoe crabs they persist as large plate-like limbs, called opercula or branchiophores, bearing the book gills, and that function in locomotion and gas exchange. In most chelicerates the opisthosomal limbs are greatly reduced and persist only as specialized structures, such as the silk-producing ...
