Tanyuromys
''Tanyuromys'' is a genus of oryzomyine rodents distributed in mountainous areas from Central America to the western part of South America. The species in this genus have historically been placed in ''Sigmodontomys'', but according to cladistic research, this genus is either sister to the clade containing ''Sigmodontomys'' and ''Melanomys'' or sister to the extinct Caribbean giant rice rat '' Megalomys''. Along with members of ''Aegialomys'' and ''Melanomys'', it occurs at some of the highest elevations known for oryzomines. Two species are known from the genus: '' T. aphrastus'' (distributed from Costa Rica to Ecuador) and the recently described '' T. thomasleei'' (endemic Endemism is the state of a species being found 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 elsew ... to Ecuador).

Tanyuromys Thomasleei
Thomas Lee's rice water rat (''Tanyuromys thomasleei'') is a rodent species belonging to the family Cricetidae.It is native exclusively to Ecuador and inhabits middle-elevation forests on the Pacific-facing slopes of the Andes.This species is found in both undisturbed and disturbed forest environments. While similar in appearance to '' T. aphrastus'', Thomas Lee's rice water rat can be distinguished by certain cranial and genetic characteristics.

Oryzomyini
Oryzomyini is a tribe of rodents in the subfamily Sigmodontinae of the family Cricetidae. It includes about 120 species in about thirty genera,Weksler et al., 2006, table 1 distributed from the eastern United States to the southernmost parts of South America, including many offshore islands. It is part of the clade Oryzomyalia, which includes most of the South American Sigmodontinae. The name ''Oryzomyini'' derives from that of its type genus, ''Oryzomys'', which means "rice rat" or "rice mouse". Many species are also known as rice rats. Taxonomy Contents of Oryzomyini An oryzomyine group was first envisaged by Oldfield Thomas in the early 20th century. He defined it to include pentalophodont species, which have a mesoloph(id) on the upper and lower molars, with a long palate (extending past the third molars). Thomas included ''Oligoryzomys'', ''Oecomys'', and ''Oryzomys'' (which included many species now in other genera), as well as '' Rhagomys'', which is currently classified ...

Ronald H
Ronald is a masculine given name derived from the Old Norse ''Rögnvaldr'', Hanks; Hardcastle; Hodges (2006) p. 234; Hanks; Hodges (2003) § Ronald. or possibly from Old English '' Regenweald''. In some cases ''Ronald'' is an Anglicised form of the Gaelic ''Raghnall'', a name likewise derived from ''Rögnvaldr''. The latter name is composed of the Old Norse elements ''regin'' ("advice", "decision") and ''valdr'' ("ruler"). ''Ronald'' was originally used in England and Scotland, where Scandinavian influences were once substantial, although now the name is common throughout the English-speaking world. A short form of ''Ronald'' is ''Ron''. Pet forms of ''Ronald'' include ''Roni'' and ''Ronnie''. ''Ronalda'' and ''Rhonda'' are feminine forms of ''Ronald''. '' Rhona'', a modern name apparently only dating back to the late nineteenth century, may have originated as a feminine form of ''Ronald''.

Endemism
Endemism is the state of a species being found 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 be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aegialomys
''Aegialomys'' is a genus of oryzomyini, oryzomyine rodents from the lowlands and mountains of western Peru and Ecuador, including the Galápagos Islands. The species in this genus have historically been placed in ''Oryzomys'', but according to cladistics, cladistic research, the genus is more closely related to a group containing, among others, ''Nectomys'' and ''Sigmodontomys'', than to ''Oryzomys''. The generic name ''Aegialomys'' means "coastal mouse" in Ancient Greek ( "coast" and "mouse") and references the mostly coastal occurrence of the genus. ''Aegialomys'' species have a greyish to buff dorsal pelage which is divided sharply from the white to light yellow ventral pelage. They have relatively short ears. There are crowns of hair at the bases of the toes. The tail is equal to or longer than the body and is darker above than below. There are two commonly recognized and described species in the genus: the mainland ''Aegialomys xanthaeolus, A. xanthaeolus'', the type speci ...

Megalomys
''Megalomys'' is a genus of rodent in the family Cricetidae, part of the tribe Oryzomyini. The genus contains five large rodents from various Caribbean islands, of which two are known to have survived into modern times, but all of which are now extinct. The last species to survive was ''M. desmarestii'' from Martinique, which became extinct after the Mount Pelée eruption in 1902. Ancient DNA analysis places ''Megalomys'' forming a clade with '' Pennatomys,'' sister to the clade containing ''Aegialomys'', '' Nesoryzomys, Melanomys'' and ''Sigmodontomys,'' having diverged from the mainland clade around 7 million years ago. It contains the following species: Recently extinct species: * ''Megalomys desmarestii'' (Martinique giant rice rat) * ''Megalomys luciae'' (Saint Lucia giant rice rat) Fossil species: *''Megalomys audreyae'' (Barbuda giant rice rat) *'' Megalomys curazensis'' (Curaçao giant rice rat) *'' Megalomys georginae'' (Barbados Barbados is an island country i ...

Caribbean
The Caribbean (, ) ( es, El Caribe; french: la Caraïbe; ht, Karayib; nl, De Caraïben) is a region of the Americas that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America. Situated largely on the Caribbean Plate, the region has more than 700 islands, islets, reefs and cays (see the list of Caribbean islands). Island arcs delineate the eastern and northern edges of the Caribbean Sea: The Greater Antilles and the Lucayan Archipelago on the north and the Lesser Antilles and the on the south and east (which includes the Leeward Antilles). They form the West Indies with the nearby Lucayan Archipelago (the Bahamas and Turks and Caicos Islands), which are considered to be part of the Caribbean despite not bordering the Caribbe ...
