The eastern mountain coati or eastern dwarf coati (Nasuella meridensis) is a small procyonid found in cloud forest and páramo at altitudes of 2,000–4,000 metres (6,600–13,100 ft) in the Andes of western Venezuela. Until 2009, it was usually included as a subspecies of the western mountain coati, but the eastern mountain coati is overall smaller, somewhat shorter-tailed on average, has markedly smaller teeth, a paler olive-brown pelage, and usually a dark mid-dorsal stripe on the back (versus more rufescent or blackish, and usually without a dark mid-dorsal stripe in the western mountain coati). When the two were combined, they were rated as Data Deficient by the IUCN, but following the split the eastern mountain coati is considered endangered.
|Eastern Mountain Coati|
Coatis, also known as the coatimundis (), are members of the raccoon family (Procyonidae) in the genera Nasua and Nasuella. They are diurnal mammals native to South America, Central America, and southwestern North America. The name coatimundi is purportedly derived from the Tupian languages of Brazil.The coati is also known in English as the hog-nosed coon.Dwarf coati
Dwarf coati can refer to several species:
Cozumel Island coati (Nasua narica nelsoni) – from Cozumel Island, Mexico.
Eastern mountain coati (Nasuella meridensis) – from the Andes in Venezuela.
Western mountain coati (Nasuella olivacea) – from the Andes in Colombia and Ecuador.IUCN Red List endangered species (Animalia)
On 19 August 2018, the IUCN Red List of Threatened Species identified 4584 endangered species, subspecies, stocks and subpopulations.List of mammals of South America
This is a list of the native wild mammal species recorded in South America. South America's terrestrial mammals fall into three distinct groups: 'old-timers', African immigrants and recent North American immigrants. The marsupials and xenarthrans are 'old-timers', their ancestors having been present on the continent since at least the very early Cenozoic Era. During the early Cenozoic, South America's only land connection was to Antarctica, so it was effectively cut off from most of the world; as the fragments of Gondwana continued to separate, this connection was lost, leaving South America an island continent. Caviomorph rodents and monkeys arrived as 'waif dispersers' by rafting across the Atlantic from Africa in the Eocene epoch, 35 million or more years ago. All the remaining nonflying mammals of South America are recent arrivals, having migrated from North America via Central America during the past seven million years as part of the Great American Interchange; this invasion, which peaked around three million years ago, was made possible when the formation of the volcanic Isthmus of Panama bridged North and South America. The newcomers out-competed and drove to extinction many unique mammals that had evolved during South America's long period of isolation, as well as some species from other classes (e.g., terror birds).South America suffered another major loss of mammal species in the Quaternary extinction event, which started around 12500 cal BP, at roughly the time of arrival of Paleoindians, and may have lasted up to several thousand years. At least 37 genera of mammals were eliminated, including most of the megafauna. While South America currently has no megaherbivore species weighing more than 1000 kg, prior to this event it had a menagerie of about 25 of them (consisting of gomphotheres, camelids, ground sloths, glyptodonts, and toxodontids – 75% of these being 'old-timers'), dwarfing Africa's present and recent total of 6.Anthropogenic climate change and the damage to its ecosystems resulting from the rapid recent growth of the human population pose a further threat to South America's biodiversity.
The list consists of those species found in the nations or overseas territories of continental South America (including their island possessions, such as the Galápagos), as well as in Trinidad and Tobago and the Falkland Islands; Panama is not included. As of May 2012, the list contains 1331 species, 340 genera, 62 families and 15 orders. Of the taxa from nonflying, nonmarine groups (992 species, 230 genera, 40 families and 12 orders), 'old-timers' comprise 14% of species, 15% of genera, 20% of families and 42% of orders; African immigrants make up 38% of species, 30% of genera, 40% of families and 17% of orders; North American invaders constitute 49% of species 55% of genera, 40% of families and 50% of orders. At the order level, the 'old-timers' are overrepresented because of their ancient local origins, while the African immigrants are underrepresented because of their 'sweepstakes' mode of dispersal.
Of the species, 9 are extinct, 29 are critically endangered, 64 are endangered, 111 are vulnerable, 64 are near-threatened, and 255 are data-deficient. Mammal species presumed extinct since AD 1500 (nine or ten cases) are included. Domestic species (e.g., the guinea pig, alpaca, and llama) and introduced species are not listed.
NOTE: this list is inevitably going to be incomplete, since new species are continually being recognized via discovery or reclassification. Places to check for missing species include the Wikipedia missing mammal species list, including recently removed entries, and the species listings in the articles for mammalian genera, especially those of small mammals such as rodents or bats.
The following tags are used to highlight each species' conservation status as assessed by the IUCN; those on the left are used here, those in the second column in some other articles:
The IUCN status of all listed species except bats was last updated during the period from March to June 2009; bats were updated in September 2009.Nasua
Nasua is a genus of coatis of the family Procyonidae. Two additional species of coatis, commonly known as mountain coatis, are placed in the genus Nasuella.Nasuella
Mountain coatis are two species of procyonid mammals from the genus Nasuella. Unlike the larger coatis from the genus Nasua, mountain coatis only weigh 1.0–1.5 kilograms (2.2–3.3 lb) and are endemic to the north Andean highlands in South America.Procyonidae
Procyonidae is a New World family of the order Carnivora. It comprises the raccoons, coatis, kinkajous, olingos, olinguitos, ringtails, and cacomistles. Procyonids inhabit a wide range of environments and are generally omnivorous.Táchira depression
The Táchira depression (Spanish: Depresión de Táchira) is a saddle of land connecting the Lake Maracaibo basin to the Orinoco basin in the state of Táchira, Venezuela.
It forms a break in the eastern Andes, separating the Tamá Massif to the west from the Cordillera de Mérida to the east.
The depression has been thought to present a barrier to the movement of species between the Colombian and Venezuelan Andes, but this effect may have been relatively low during the recent ice ages. The mountains of the region have potential for coffee farming and hydroelectric power generation, while the lower levels are suitable for farming.
