Myotis Nyctor
The Barbados myotis (''Myotis nyctor'') is a species of bat found in the Lesser Antilles. It was previously considered a subspecies of Schwartz's myotis, ''Myotis martiniquensis'', but was elevated to species rank in 2012. Taxonomy and etymology In 1973, American zoologist Richard K. LaVal described Schwartz's myotis from specimens collected in Martinique. A year later in 1974, LaVal identified more Schwartz's myotis in Barbados; he decided that each population was a subspecies. In Martinique, the population would be called ''M. m. martiniquensis'', and the population in Barbados would be called ''M. m. nyctor''. A 2012 study determined that there was a genetic distance of 8-9% between the two subspecies. The two subspecies were actually paraphyletic, with ''M. m. nyctor'' more closely related to an unrecognized species in Suriname. On the basis of their genetic and morphological divergence, the authors of the 2012 paper recommended that ''M. m. nyctor'' be elevated to species ra ...

Lesser Antilles
The Lesser Antilles ( es, link=no, Antillas Menores; french: link=no, Petites Antilles; pap, Antias Menor; nl, Kleine Antillen) are a group of islands in the Caribbean Sea. Most of them are part of a long, partially volcanic island arc between the Greater Antilles to the north-west and the continent of South America."West Indies." ''Merriam-Webster's Geographical Dictionary'', 3rd ed. 2001. () Springfield, MA: Merriam-Webster Inc., p. 1298. The islands of the Lesser Antilles form the eastern boundary of the Caribbean Sea where it meets the Atlantic Ocean. Together, the Lesser Antilles and the Greater Antilles make up the Antilles. (Somewhat confusingly, the word Caribbean is sometimes used to refer only to the Antilles, and sometimes used to refer to a much larger region.) The Lesser and Greater Antilles, together with the Lucayan Archipelago, are collectively known as the West Indies.

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetic Distance
Genetic distance is a measure of the genetic divergence between species or between populations within a species, whether the distance measures time from common ancestor or degree of differentiation. Populations with many similar alleles have small genetic distances. This indicates that they are closely related and have a recent common ancestor. Genetic distance is useful for reconstructing the history of populations, such as the multiple human expansions out of Africa. It is also used for understanding the origin of biodiversity. For example, the genetic distances between different breeds of domesticated animals are often investigated in order to determine which breeds should be protected to maintain genetic diversity. Biological foundation In the genome of an organism, each gene is located at a specific place called the locus for that gene. Allelic variations at these loci cause phenotypic variation within species (e.g. hair colour, eye colour). However, most alleles do not hav ...

Paraphyly
In taxonomy, a group is paraphyletic if it consists of the group's last common ancestor and most of its descendants, excluding a few monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia ( reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor, including all extant reptiles as well as the extinct synapsids, ...

Grenada
Grenada ( ; Grenadian Creole French: ) is an island country in the West Indies in the Caribbean Sea at the southern end of the Grenadines island chain. Grenada consists of the island of Grenada itself, two smaller islands, Carriacou and Petite Martinique, and several small islands which lie to the north of the main island and are a part of the Grenadines. It is located northwest of Trinidad and Tobago, northeast of Venezuela and southwest of Saint Vincent and the Grenadines. Its size is , and it had an estimated population of 112,523 in July 2020. Its capital is St. George's. Grenada is also known as the "Island of Spice" due to its production of nutmeg and mace crops. Before the arrival of Europeans in the Americas, Grenada was inhabited by the indigenous peoples from South America. Christopher Columbus sighted Grenada in 1498 during his third voyage to the Americas. Following several unsuccessful attempts by Europeans to colonise the island due to resistance from res ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Barbados
Barbados is an island country in the Lesser Antilles of the West Indies, in the Caribbean region of the Americas, and the most easterly of the Caribbean Islands. It occupies an area of and has a population of about 287,000 (2019 estimate). Its capital and largest city is Bridgetown. Inhabited by Island Caribs, Kalinago people since the 13th century, and prior to that by other Indigenous peoples of the Americas, Amerindians, Spanish navigators took possession of Barbados in the late 15th century, claiming it for the Crown of Castile. It first appeared on a Spanish map in 1511. The Portuguese Empire claimed the island between 1532 and 1536, but abandoned it in 1620 with their only remnants being an introduction of wild boars for a good supply of meat whenever the island was visited. An Kingdom of England, English ship, the ''Olive Blossom'', arrived in Barbados on 14 May 1625; its men took possession of the island in the name of James VI and I, King James I. In 1627, the first ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouse-eared Bat
The mouse-eared bats or myotises are a diverse and widespread genus (''Myotis'') of bats within the family Vespertilionidae. The noun "''myotis''" itself is a New Latin construction, from the Greek "''muós'' (meaning "mouse") and "''oûs''" (meaning ear), literally translating to "mouse-eared". Relationships ''Myotis'' has historically been included in the subfamily Vespertilioninae, but was classified in its own subfamily, Myotinae, by Nancy Simmons in 1998. In her 2005 classification in ''Mammal Species of the World'', Simmons listed the genera ''Cistugo'' and ''Lasionycteris'' in the Myotinae in addition to ''Myotis'' itself.Simmons, 2005, p. 499 However, molecular data indicate that ''Cistugo'' is distantly related to all other Vespertilionidae, so it was reclassified into its own family, the Cistugidae, and that ''Lasionycteris'' belongs in the Vespertilioninae.Roehrs et al., 2010 The genus '' Submyotodon'' has since been added to the subfamily, making it and ''Myotis'' it ...

Myotis Attenbourghi
Sir David Attenborough's myotis (''Myotis attenboroughi'') is a species of small bat in the family Vespertilionidae that is endemic to the Caribbean island of Tobago. Its presence on nearby Trinidad is as yet uncertain. It is the only mammal species currently known to be endemic to Trinidad and Tobago. It was named after famed English naturalist Sir David Attenborough. It was formerly assigned to '' Myotis nigricans'' until a 2017 study revealed that it was a distinct, previously unknown species. It is the sister species to a clade containing ''M.'' cf. ''handleyi'', '' M. nesopolus'', and 3 possibly undescribed species from South and Central America. It can be distinguished from all other Caribbean ''Myotis'' by its small skull and steeply sloping frontals. It feeds on moths and other small flying nocturnal insects, and roosts in caves, tree hollows, and the attics of buildings.

Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships.
