Ligidium Hypnorum
''Ligidium hypnorum'' is a species of woodlouse found across Europe and western Asia. It is a fast-moving, active species whichthat rarely grows longer than . accessed through the Natural Environment Research Council, NERC Open Access Research Archive (NORA) It is dark and shiny, and is similar in appearance to the common species ''Philoscia muscorum'', and also the rarer ''Oritoniscus flavus''. In Great Britain, it was first discovered at Copthorne Hundred, Copthorne Common, Surrey, in 1873, and most later records are also from South East England. It is considered a good indicator species for ancient woodland. Disease Prior to the recognition of ''Invertebrate iridescent virus 31'' (IIV-31) in 1980, blue individuals of ''L. hypnorum'' had been discovered, which were interpreted to be new subspecies, and were described as such: ''L. hypnorum coeruleum'' Dominique Auguste Lereboullet, Lereboullet 1843 and ''L. hypnorum amethystinum'' Schöbl 1861 (in reference to cerulean and Amet ...

Georges Cuvier
Jean Léopold Nicolas Frédéric, Baron Cuvier (; 23 August 1769 – 13 May 1832), known as Georges Cuvier, was a French natural history, naturalist and zoology, zoologist, sometimes referred to as the "founding father of paleontology". Cuvier was a major figure in natural sciences research in the early 19th century and was instrumental in establishing the fields of comparative anatomy and paleontology through his work in comparing living animals with fossils. Cuvier's work is considered the foundation of vertebrate paleontology, and he expanded Linnaean taxonomy by grouping classes into phylum, phyla and incorporating both fossils and living species into the classification. Cuvier is also known for establishing extinction as a fact—at the time, extinction was considered by many of Cuvier's contemporaries to be merely controversial speculation. In his ''Essay on the Theory of the Earth'' (1813) Cuvier proposed that now-extinct species had been wiped out by periodic catastrophi ...

Woodlice
A woodlouse (plural woodlice) is an isopod crustacean from the polyphyleticThe current consensus is that Oniscidea is actually triphyletic suborder Oniscidea within the order Isopoda. They get their name from often being found in old wood. The first woodlice were marine isopods which are presumed to have colonised land in the Carboniferous, though the oldest known fossils are from the Cretaceous period. They have many common names and although often referred to as terrestrial isopods, some species live semiterrestrially or have recolonised aquatic environments. Woodlice in the families Armadillidae, Armadillidiidae, Eubelidae, Tylidae and some other genera can roll up into a roughly spherical shape ( conglobate) as a defensive mechanism; others have partial rolling ability, but most cannot conglobate at all. Woodlice have a basic morphology of a segmented, dorso-ventrally flattened body with seven pairs of jointed legs, specialised appendages for respiration and like ...

List Of Woodlice Of The British Isles
Woodlice are the most species-rich group of terrestrial crustaceans. Of the 4,000 described species found worldwide, 35 species in 10 families are native to the British Isles. One of these species, '' Acaeroplastes melanurus'', had been considered extinct in the British Isles but was rediscovered in 2002 at its only site (Howth, County Dublin, Ireland), and a further ten species have become naturalised in greenhouses, presumably transported with exotic plants. accessed through the NERC Open Access Research Archive (NORA) Five species are especially common throughout the British Isles, and are known as the "famous five species". They are ''Oniscus asellus'' (the common shiny woodlouse), ''Porcellio scaber'' (the common rough woodlouse), ''Philoscia muscorum'' (the common striped woodlouse), '' Trichoniscus pusillus'' (the common pygmy woodlouse) and ''Armadillidium vulgare'' (the common pill bug). One species, '' Metatrichoniscoides celticus'', is endemic to Glamorgan, and is listed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amethyst (color)
Lavender is a light shade of purple or violet. It applies particularly to the color of the flower of the same name. The web color called lavender is displayed at right—it matches the color of the very palest part of the lavender flower; however, the more saturated color shown below as '' floral lavender'' more closely matches the average color of the lavender flower as shown in the picture and is the tone of lavender historically and traditionally considered ''lavender'' by the average person as opposed to those who are website designers. The color lavender might be described as a ''medium purple'' or a ''light pinkish-purple''. The term ''lavender'' may be used in general to apply to a wide range of pale, light or grayish-purples but only on the blue side. Lilac is pale purple on the pink side. In paints, the color lavender is made by mixing purple and white paint. The first recorded use of the word ''lavender'' as a color term in English was in 1705. Historical developme ...

Cerulean
Cerulean (), also spelled caerulean, is a shade of blue ranging between azure and a darker sky blue. The first recorded use of ''cerulean'' as a colour name in English was in 1590. The word is derived from the Latin word '' caeruleus'', "dark blue, blue, or blue-green", which in turn probably derives from ''caerulum'', diminutive of ''caelum'', "heaven, sky". "Cerulean blue" is the name of a pigment. The pigment was discovered in the late eighteenth century and designated as cerulean blue in the nineteenth century. Cerulean blue pigment The primary chemical constituent of the pigment is cobalt(II) stannate (). The precise hue of the pigment is dependent on a variable silicate component. The pigment Cerulean blue was discovered in 1789 by the Swiss chemist Albrecht Höpfner. Subsequently, there was a limited German production under the name of ''Cölinblau''. It was in 1860 first marketed in the United Kingdom by colourman George Rowney, as "coeruleum". Other nineteenth c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dominique Auguste Lereboullet
Dominique Auguste Lereboullet was a French doctor and zoologist. He was born on 19 September 1804 at Épinal, and died of an apoplectic fit on 6 October 1865 in Strasbourg. He began his studies at Colmar before specialising in medicine at Strasbourg where he graduated as a doctor with a thesis about cholera. While practising medicine, he kept up a series of studies into comparative anatomy of animals. On the departure of Georges Louis Duvernoy to Paris, Lereboullet took the opportunity to occupy the chair of zoology and comparative anatomy at the faculty of science in Strasbourg. Lereboullet was dean of the Faculty of Sciences and professor of zoology at the University of Strasbourg, as well as the director of ' (the city's natural history museum). His zoological studies included works on the genitals of vertebrates, foie gras, comparative embryology of fish and carcinology Carcinology is a branch of zoology that consists of the study of crustaceans, a group of arthropods ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invertebrate Iridescent Virus 31
''Invertebrate iridescent virus 31'' (IIV-31), also known informally as isopod iridovirus, is a species of invertebrate iridescent virus in the genus ''Iridovirus''. Oniscidea (commonly known by a variety of names including ''woodlouse'', ''pillbug'', ''slater'', ''rolly-polly'', ''potato bug'', et al.) serve as hosts. Infection is associated with decreased responsiveness in the host, increased mortality, and most strikingly, the emergence of an iridescent blue or bluish-purple colour due to the reflection of light off a paracrystalline arrangement of virions within the tissues. Taxonomy In earlier centuries, blue individuals of otherwise drab oniscidean species had been discovered. They were sometimes interpreted to be new subspecies and were described as such: ''Ligidium hypnorum coeruleum'' Lereboullet 1843 and ''L. hypnorum amethystinum'' Schöbl 1861 (in reference to cerulean and amethyst, respectively). In 1980, the first research was published showing that the phenomeno ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient Woodland
In the United Kingdom, an ancient woodland is a woodland that has existed continuously since 1600 or before in England, Wales and Northern Ireland (or 1750 in Scotland). Planting of woodland was uncommon before those dates, so a wood present in 1600 is likely to have developed naturally. In most ancient woods, the trees and shrubs have been cut down periodically as part of the management cycle. Provided that the area has remained as woodland, the stand is still considered ancient. Since it may have been cut over many times in the past, ancient woodland does not necessarily contain very old trees. For many species of animal and plant, ancient woodland sites provide the sole habitat, and for many others, conditions on these sites are much more suitable than those on other sites. Ancient woodland in the UK, like rainforest in the tropics, is home to rare and threatened species. For these reasons ancient woodland is often described as an irreplaceable resource, or 'critical natural ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indicator Species
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water body, water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollution, pollutants in the ecosystem and about how long a problem may have been present, which Water pollution#Measurement, physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative property, quantitative information on the quality of Environment (biophysical), the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional inform ...

Surrey
Surrey () is a ceremonial and non-metropolitan county in South East England, bordering Greater London to the south west. Surrey has a large rural area, and several significant urban areas which form part of the Greater London Built-up Area. With a population of approximately 1.2 million people, Surrey is the 12th-most populous county in England. The most populated town in Surrey is Woking, followed by Guildford. The county is divided into eleven districts with borough status. Between 1893 and 2020, Surrey County Council was headquartered at County Hall, Kingston-upon-Thames (now part of Greater London) but is now based at Woodhatch Place, Reigate. In the 20th century several alterations were made to Surrey's borders, with territory ceded to Greater London upon its creation and some gained from the abolition of Middlesex. Surrey is bordered by Greater London to the north east, Kent to the east, Berkshire to the north west, West Sussex to the south, East Sussex to ...
