Zospeum Zaldivarae
''Zospeum zaldivarae'' is a cave-dwelling species of air-breathing 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. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as .... Description This species has an average shell height of ca. 1.5 mm and an average shell width of ca. 1.2 mm. It is larger, wider and less elongated compared to other ''Zospeum'' species. The shell is transparent, when fresh, and chalky white with age. It has a turbinate-conical shape with approximately 5 1/2 regularly coiled, convex, rounded whorls. The last whorl is large, tumid and encompasses ca. 2/3 of the shell height. The opening (aperture) of the shell is crescent-shaped. ''Zospesum zaldivarae'' seems to be polymorphic regarding the presence/absence of the apertural barriers. Some individuals show an apertural dentition, some not. The ...

Troglofauna
Troglofauna are small cave-dwelling animals that have adapted to their dark surroundings. Troglofauna and stygofauna are the two types of subterranean fauna (based on life-history). Both are associated with subterranean environments – troglofauna are associated with caves and spaces above the water table and stygofauna with water. Troglofaunal species include spiders, insects, myriapods and others. Some troglofauna live permanently underground and cannot survive outside the cave environment. Troglofauna adaptations and characteristics include a heightened sense of hearing, touch and smell. Loss of under-used senses is apparent in the lack of pigmentation as well as eyesight in most troglofauna. Troglofauna insects may exhibit a lack of wings and longer appendages. Ecological categories Troglofauna are divided into three main categories based on their ecology: * Troglobionts (or troglobites): species, or populations of species, strictly bound to subterranean habitats. * Troglophi ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulmonate
Pulmonata or pulmonates, is an informal group (previously an order, and before that a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts. Linnean taxonomy The taxonomy of this group according to the taxonomy of the Ga ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

Sierra Salvada
Sierra Salvada ( eu, Gorobel) is a mountain range situated to the northwest of Burgos (Spain), and it is also part of Alava and Orduña (an enclave on Biscay). The southern slope of this mountain range, whose rivers flow to the mediterranean sea, is included in the province of Burgos. However, the north slope is part of the Autonomous Community of the Basque Country. The rivers of this area of Sierra Salvada flow to the Cantabrian coast. Sierra Salvada is famous because of its peculiar shape, created by its north steep slope, in length, and because of its biodiversity, That is why Sierra Salvada is considered a Special Protection Area (SPA), in order to protect the different species of birds. History This mountain range has been very important between the 16th and 18th centuries, as a communication way between Castilla and the Cantabrian. It is considered an important trade route that connected the Northern Peninsula, and therefore, it was very significant on the commerc ...

Province Of Burgos
The Province of Burgos is a province of northern Spain, in the northeastern part of the autonomous community of Castile and León. It is bordered by the provinces of Palencia, Cantabria, Vizcaya, Álava, La Rioja, Soria, Segovia, and Valladolid. Its capital is the city of Burgos. The Cartularies of Valpuesta from the monastery Santa María de Valpuesta, in Burgos, are considered to be the oldest known documents containing words written in the Spanish language. Overview Since 1964, archaeologists have been working at numerous areas of the Archaeological Site of Atapuerca, where they have found ancient hominid and human remains, the former dating to more than one million years ago, with artefacts from the Palaeolithic and Bronze Ages of man. The site has been designated a UNESCO World Heritage Site. The province has an area of and a population of approximately 375,000 of whom nearly half live in the capital. The other locations higher than 20,000 inhabitants apart from Burgo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Niphargus Speleoloical Team
''Niphargus'' is by far the largest genus of its family, the Niphargidae, and the largest of all freshwater amphipod genera. Usually, these animals inhabit caves or groundwater. They occur in western Eurasia, in regions that were not covered by the Pleistocene ice sheets. They are found throughout most of Europe with the notable exception of the Nordics and they are also largely missing from Iberia. The genus extends into Asia as far as the Arabian Peninsula and Iran. In their main range – the central Mediterranean region through Central and Eastern Europe to the Ukraine – they are among the most significant organisms inhabiting the groundwater. In the Dinaric Alps alone there are at least 45 species. There are also six species in the British Isles (the northernmost ''Niphargus''): ''N. aquilex'', ''N. fontanus'', ''N. glenniei'' and ''N. kochianus'' of Great Britain, and ''N. irlandicus'' and ''N. wexfordensis'' of Ireland.
