Atlantica Calathoides
''Atlantica calathoides'' is a species of land snail belonging to the family Gastrodontidae. Distribution This species is endemic to Madeira, Portugal. Description (Original description) This species is very closely allied to the Madeiran '' Atlantica gueriniana'' (R. T. Lowe, 1852), but is assuredly a genuine species, and not a merely large fossil form of that shell. It is distinguished by its larger size, less discoidal shape, greater convexity beneath, more elevated spire, obsolete keel, deeply impressed suture, and much coarser, more abrupt, and prominent ribs above, resembling, in the latter respect and in the abrupt ending of the ribs at the obsolete keel or angle of the last whorl, '' Janulus calathus'' (R. T. Lowe, 1852) (taxon inquirendum) or ''Janulus bifrons'' (R. T. Lowe, 1852). Historical account The species was first described by Richard Thomas Lowe in 1863 as ''Helix calathoides''. In 2008, reserve warden Isamberto Silva and biologist Dinarte Teixeira redisc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Thomas Lowe
Richard Thomas Lowe (1802–1874) was an English botanist, ichthyologist, malacologist, and clergyman. In 1825 he graduated from Christ's College, Cambridge, and in the same year he took holy orders. In 1832 he became a clergyman in the Madeira Islands, where he was also a part-time naturalist, extensively studying the local flora and fauna. He wrote a book on the Madeiran flora. He died in 1874 when the ship he was on was wrecked off the Isles of Scilly. Taxa Lowe named and described numerous molluscan taxa, including: * '' Caseolus'', a land snail genus and eight species within it * '' Lemniscia'', a land snail A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails.

Endemic Fauna Of Madeira
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becoming ...

Taxa Named By Richard Thomas Lowe
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landslide
Landslides, also known as landslips, rockslips or rockslides, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, mudflows, shallow or deep-seated slope failures and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Landslides are frequently made worse by human development (such as urban sprawl) and resource exploitation (such as mining and deforestation). Land degradation freque ...

Ground Beetle
Ground beetles are a large, cosmopolitan distribution, cosmopolitan family (biology), family of beetles, the Carabidae, with more than 40,000 species worldwide, around 2,000 of which are found in North America and 2,700 in Europe. As of 2015, it is one of the 10 most species-rich animal families. They belong to the Adephaga. Members of the family are primarily Carnivore, carnivorous, but some members are Herbivore, herbivorous or Omnivore, omnivorous. Description and ecology Although their body shapes and coloring vary somewhat, most are shiny black or metallic and have ridged wing covers (elytra). The elytra are fused in some species, particularly the large Carabinae, rendering the beetles unable to fly. The species ''Mormolyce phyllodes'' is known as violin beetle due to their peculiarly shaped elytra. All carabids except the quite primitive flanged bombardier beetles (Paussinae) have a groove on their arthropod leg, fore leg tibiae bearing a comb of hairs used for cleaning the ...

Mouse
A mouse (: mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (''Mus musculus''). Mice are also popular as pets. In some places, certain kinds of Apodemus, field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size. Generally, when a muroid rodent is discovered, its common name includes the term ''mouse'' if it is smaller, or ''rat'' if it is larger. The common terms ''rat'' and ''mouse'' are not Taxonomy (biology), taxonomically specific. Typical mice are classified in the genus ''Mus (genus), Mus'', but the term ''mouse'' is not confined to members of ''Mus'' and can also apply to species from other genera such as the deer mouse, deer mouse (''Peromyscus''). Fancy mouse, Domestic mice sold as pets often differ substantially in size f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pteridium Aquilinum
''Pteridium aquilinum'', commonly called bracken, brake, pasture brake, common bracken, and also known as eagle fern, is a species of fern occurring in temperate and subtropical regions in both hemispheres. Originally native to Eurasia and North America, the extreme lightness of its spores has led to it achieving a cosmopolitan distribution. Description Common bracken is a herbaceous perennial plant, deciduous in winter. The large, roughly triangular fronds are produced singly, arising upwards from an underground rhizome, and grow to tall; the main stem, or stipe, is up to in diameter at the base. It dies back to ground level in autumn. The rhizome grows up to deep, about in diameter, and up to long. Because it regrows in the spring from an underground rhizome, ''P. aquilinum'' tends to be found in dense colonies of genetically identical fronds. Such colonies can be as much as 650 years of age, with individual rhizomes living up to 72 years. One colony at Raakkyla, North Ka ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS. The Quaternary is typically defined by the Quaternary glaciation, the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four succ ...

Deserta Grande Island
The Deserta Grande Island is the main island of the Desertas Islands archipelago, a small chain of three islands in the Portuguese Madeira Islands Archipelago of Macaronesia. It is located southeast of Madeira Island, off the western coast of North Africa in the Atlantic Ocean. Nature reserve The island is part of the Desertas Islands nature reserve, with a warden's base midway along the western coast. South of the base, no approach to the island closer than 100 m is permitted in order to protect the critically endangered Mediterranean monk seal breeding population. Access is permitted to the north of the nature base. Some activities, such as line and spear fishing, are banned. The large, critically endangered wolf spider '' Hogna ingens'' is endemic to Deserta Grande. The island has breeding Cory's shearwaters, Bulwer's petrels and Madeiran storm-petrels. The Madeiran land snails are endemic to the islands. They had not been observed for over a century, and was ass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
