Escalera's Bat
Escalera's bat (''Myotis escalerai'') is a European bat in the genus '' Myotis'', found in Spain (including the Balearic Islands), Portugal, and far southern France. Although the species was first named in 1904, it was included in Natterer's bat (''Myotis nattereri'') until molecular studies, first published in 2006, demonstrated that the two are distinct species. ''M. escalerai'' is most closely related to an unnamed species from Morocco. Unlike ''M. nattereri'', which lives in small groups in tree holes, ''M. escalerai'' forms large colonies in caves. Females start to aggregate in late spring in maternity colonies, and their young are born in summer. The species spends each winter in hibernation colonies, usually in caves or basements. ''M. escalerai'' is a medium-sized, mostly gray bat, with lighter underparts. It has a pointed muzzle, a pink face, and long ears. The wings are broad and the species is an agile flyer. Wingspan is and body mass is . Though ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

テ]gel Cabrera (naturalist)
テ]gel Cabrera (19 February 1879 – 8 July 1960) was a Spanish zoologist. He was born in Madrid and studied at the Universidad Central, Madrid (now part of the Universidad Complutense de Madrid). He worked the National Museum of Natural Sciences from 1902, going on several collecting expeditions to Morocco. In 1907, he proposed that the Iberian wolf was a separate subspecies, which he named ''Canis lupus signatus''. In 1925 Cabrera went to Argentina and remained there for the rest of his life. He was head of the Department of Vertebrate Paleontology at the Museo de La Plata, and made collecting trips to Patagonia and Catamarca. In Patagonia he discovered the first Jurassic dinosaur of South America; he thus began a series of discoveries in this region, one of the richest in dinosaur remains. He supervised the doctoral work of some of the first palaeontologists of South America, including Mathilde Dolgopol de Sテ。ez and Dolores Lテウpez Aranguren. His son テ]gel Lulio Cab ...

Mitochondrial DNA
Mitochondrial DNA (mtDNA or mDNA) is the DNA located in mitochondria, cellular organelles within eukaryotic cells that convert chemical energy from food into a form that cells can use, such as adenosine triphosphate (ATP). Mitochondrial DNA is only a small portion of the DNA in a eukaryotic cell; most of the DNA can be found in the cell nucleus and, in plants and algae, also in plastids such as chloroplasts. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that the human mtDNA includes 16,569 base pairs and encodes 13 proteins. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits an examination of the relatedness of populations, and so has become important in anthropology and biogeography. Origin Nuclear and mitochondrial DNA are thought to be of separate evolutionary origin, with the mtDNA being derived ...

Tragus (anatomy)
The tragus is a small pointed eminence of the external ear, situated in front of the concha, and projecting backward over the meatus. It also is the name of hair growing at the entrance of the ear. Its name comes the Ancient Greek (), meaning 'goat', and is descriptive of its general covering on its under surface with a tuft of hair, resembling a goat's beard. The nearby antitragus projects forwards and upwards. Because the tragus faces rearwards, it aids in collecting sounds from behind. These sounds are delayed more than sounds arriving from the front, assisting the brain to sense front vs. rear sound sources. In a positive fistula test (for the presence of a fistula from cholesteatoma to the labyrinth), pressure on the tragus causes vertigo or eye deviation by inducing movement of perilymph. Other animals The tragus is a key feature in many bat species. As a piece of skin in front of the ear canal, it plays an important role in directing sounds into the ear for prey locatio ...

Zenati Myotis
The Zenati myotis (''Myotis zenatius'') is a rare species of mouse-eared bat that is restricted to North Africa. It is very rare in Morocco, being restricted to just four localities ranging from the Rif to the Atlas Mountains. Aside from Morocco, it is only known from three populations in northern Algeria, although it is possible that populations may exist in Tunisia. There are two genetically distinct haplogroups in the Atlas Mountains that could be further considered distinct subpopulations. It is a member of the Natterer's bat (''M. nattereri'') species complex and closely resembles the cryptic myotis The cryptic myotis (''Myotis crypticus'') is a European vespertilionid bat. It is a member of the Natterer's bat (''M. nattereri'') species complex, and is also the closest living relative of ''M. nattereri''. It is mostly distributed across Eur ...

Undescribed Taxon
In taxonomy, an undescribed taxon is a taxon (for example, a species) that has been discovered, but not yet formally described and named. The various Nomenclature Codes specify the requirements for a new taxon to be validly described and named. Until such a description has been published, the taxon has no formal or official name, although a temporary, informal name is often used. A published scientific name may not fulfil the requirements of the Codes for various reasons. For example, if the taxon was not adequately described, its name is called a '' nomen nudum''. It is possible for a taxon to be "undescribed" for an extensive period of time, even if unofficial descriptions are published. An undescribed species may be referred to with the genus name, followed by "sp"., but this abbreviation is also used to label specimens or images that are too incomplete to be identified at the species level. In some cases, there is more than one undescribed species in a genus. In this case, th ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cytochrome B
Cytochrome b within both molecular and cell biology, is a protein found in the mitochondria of eukaryotic cells. It functions as part of the electron transport chain and is the main subunit of transmembrane cytochrome bc1 and b6f complexes. Function In the mitochondrion of eukaryotes and in aerobic prokaryotes, cytochrome b is a component of respiratory chain complex III () 窶 also known as the bc1 complex or ubiquinol-cytochrome c reductase. In plant chloroplasts and cyanobacteria, there is an analogous protein, cytochrome b6, a component of the plastoquinone-plastocyanin reductase (), also known as the b6f complex. These complexes are involved in electron transport, the pumping of protons to create a proton-motive force ( PMF). This proton gradient is used for the generation of ATP. These complexes play a vital role in cells. Structure Cytochrome b/b6 is an integral membrane protein of approximately 400 amino acid residues that probably has 8 transmembrane segments. ...

Alps
The Alps () ; german: Alpen ; it, Alpi ; rm, Alps ; sl, Alpe . are the highest and most extensive mountain range system that lies entirely in Europe, stretching approximately across seven Alpine countries (from west to east): France, Switzerland, Italy, Liechtenstein, Austria, Germany, and Slovenia. The Alpine arch generally extends from Nice on the western Mediterranean to Trieste on the Adriatic and Vienna at the beginning of the Pannonian Basin. The mountains were formed over tens of millions of years as the African and Eurasian tectonic plates collided. Extreme shortening caused by the event resulted in marine sedimentary rocks rising by thrusting and folding into high mountain peaks such as Mont Blanc and the Matterhorn. Mont Blanc spans the French窶的talian border, and at is the highest mountain in the Alps. The Alpine region area contains 128 peaks higher than . The altitude and size of the range affect the climate in Europe; in the mountains, precipitation ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cryptic Myotis
The cryptic myotis (''Myotis crypticus'') is a European vespertilionid bat. It is a member of the Natterer's bat (''M. nattereri'') species complex, and is also the closest living relative of ''M. nattereri''. It is mostly distributed across European countries bordering the Mediterranean Sea, from Spain west to Austria, north to Switzerland, and south to most of the Italian Peninsula. Populations of similar bats in southern Italy and Sicily display significant genetic divergence from ''M. crypticus'', and thus may represent a unique taxonomic entity that requires more study. It is found in a wide range of altitudes, from sea level to 1000 meters above. It feeds in forest and grassland habitats and roosts in tree hollows as well as man-made structures. In autumn, ''M. crypticus'' swarms with other ''Myotis'' in large numbers, and overwinters Overwintering is the process by which some organisms pass through or wait out the winter season, or pass through that period of the year w ...

Iberian Peninsula
The Iberian Peninsula (), ** * Aragonese and Occitan: ''Peninsula Iberica'' ** ** * french: Pテゥninsule Ibテゥrique * mwl, Penテュnsula Eibテゥrica * eu, Iberiar penintsula also known as Iberia, is a peninsula in southwestern Europe, defining the westernmost edge of Eurasia. It is principally divided between Spain and Portugal, comprising most of their territory, as well as a small area of Southern France, Andorra, and Gibraltar. With an area of approximately , and a population of roughly 53 million, it is the second largest European peninsula by area, after the Scandinavian Peninsula. Name Greek name The word ''Iberia'' is a noun adapted from the Latin word "Hiberia" originating in the Ancient Greek word 眈クホイホキマ∃ッホア ('), used by Greek geographers under the rule of the Roman Empire to refer to what is known today in English as the Iberian Peninsula. At that time, the name did not describe a single geographical entity or a distinct population; the same name was us ...

DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence 窶 the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cryptic Species
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
