Armadillidium Quinquepustulatum
''Armadillidium quinquepustulatum'' is a European species of woodlouse endemic to France. It is a relatively small to medium-sized species that belongs to the so-called "''Armadillidium maculatum'' group". Taxonomy ''Armadilliidum quinquepustulatum'' belongs to the "Armadillidiae" section of the genus, which is characterized by rib-like side edges of the forehead that never form a "frontal brim" along with the frontal shield, a frontal triangle with lateral edges that never reach the areas of the ocelli, relatively steeply-dropping epimera on all tergites and anterior lobes of the first pair of epimera that are usually either not curved upwards or with a slight hint of a bend. Additionally, the species is a member of the "''Armadillidium maculatum'' group", which itself is divided into two subgroups: the "Eastern subgroup", distributed in Eastern Europe and the Balkans and containing 5 species ('' A. albomarginatum'', '' A. bulgaricum'', '' A. flavoscutatum'', '' A. klugi ...

Budde-Lund
Gustav Henrik Andreas Budde-Lund (11 January 1846 – 19 September 1911) was a Danish invertebrate zoologist. In 1868, he co-founded the '' Entomologisk Forening'', alongside Rasmus William Traugott Schlick, Carl August Møller, Andreas Haas and Ivar Frederik Christian Ammitzbøll. He was a student of entomologist J. C. Schiødte, and became a leading authority on terrestrial isopods (woodlice, pill bugs and relatives), describing over 70 genera and around 500 species. He married in 1875 and in 1885 produced his seminal work ''Crustacea Isopoda terrestria''. The woodlouse genus '' Buddelundiella'' was named in Budde-Lund's honour by Filippo Silvestri Filippo Silvestri (22 June 1873 – 10 June 1949) was an Italian entomologist. He specialised in world Protura, Thysanura, Diplura and Isoptera, but also worked on Hymenoptera, Myriapoda and Italian Diptera. He is also noted for describing an ... in 1897.

Italy
Italy ( it, Italia ), officially the Italian Republic, ) or the Republic of Italy, is a country in Southern Europe. It is located in the middle of the Mediterranean Sea, and its territory largely coincides with the homonymous geographical region. Italy is also considered part of Western Europe, and shares land borders with France, Switzerland, Austria, Slovenia and the enclaved microstates of Vatican City and San Marino. It has a territorial exclave in Switzerland, Campione. Italy covers an area of , with a population of over 60 million. It is the third-most populous member state of the European Union, the sixth-most populous country in Europe, and the tenth-largest country in the continent by land area. Italy's capital and largest city is Rome. Italy was the native place of many civilizations such as the Italic peoples and the Etruscans, while due to its central geographic location in Southern Europe and the Mediterranean, the country has also historically been home ...

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 ...

Massif Des Maures
The Massif des Maures (, "plateau of the Moors") is a small mountain range in southeastern France. It is located in the department of Var, near Fraxinet and between Hyères and Fréjus. Its highest point, at ''Signal de la Sauvette'', is high. Geography The Massif des Maures is a low mountain range about long and wide. Its highest point is high. It lies between the River Argens and the River Réal Martin to the north and the Mediterranean coast to the south, the River Durance to the west and the foothills of the Alps to the east, between Hyères and Fréjus. The winters are mild and the amounts of precipitation are low, especially in the summer when many of the streams run dry. The sides of the hills are steep, the soil is thin and there are few settlements; cultivated crops include grapes, citrus, olives, figs, mulberries and almonds. The detailed geography of the massif is complex; it is arranged along three main ridge lines, oriented west/southwest to east/northeast, the ...

Pleopod
The decapod ( crustaceans such as a crab, lobster, shrimp or prawn) is made up of 20 body segments grouped into two main body parts: the cephalothorax and the pleon (abdomen). Each segment may possess one pair of appendages, although in various groups these may be reduced or missing. They are, from head to tail: Cephalothorax Head # antennules # antennae #mandibles # first maxillae # second maxillae The head also bears the (usually stalked) compound eyes. The distal portion of a mandible or maxilla which has a sensory function is known as a palp. Thorax / pereon #first maxillipeds #second maxillipeds #third maxillipeds #first pereiopods #second pereiopods #third pereiopods #fourth pereiopods #fifth pereiopods Maxillipeds are appendages modified to function as mouthparts. Particularly in the less advanced decapods, these can be very similar to the pereiopods. Pereiopods are primarily walking legs and are also used for gathering food. They are also the ten legs from which decapo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Sympatric
In biology, two related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter one another. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and do no ...

Armadillidium Simoni
''Armadillidium'' () is a genus of the small terrestrial crustacean known as the woodlouse. ''Armadillidium'' are also commonly known as pill woodlice, leg pebbles, pill bugs, roly-poly, or potato bugs, and are often confused with pill millipedes such as ''Glomeris marginata''. They are characterised by their ability to roll into a ball ("volvation") when disturbed. Distribution and habitat They typically feed on moss, algae, bark and other decaying organic matter. They are usually found in moist areas such as decomposing leaf matter and soil. ''Armadillidium vulgare'' is the most abundant species in Europe and has been introduced worldwide. However, the vast majority of species are endemic to small regions close to the Mediterranean Sea, in much lower numbers than common species such as ''A. vulgare'', and hence are understudied. Description Unlike other terrestrial arthropods such as insects and spiders, pill bugs do not have a waxy cuticle that would reduce evaporation from th ...
