Black Four-eyed Opossum
The black four-eyed opossum (''Philander nigratus'') is a species of opossum from South America. Taxonomy This species was originally described as a subspecies of the gray four-eyed opossum under the name ''Metachirus opossum nigratus''. The Spanish zoologist Ángel Cabrera (naturalist), Ángel Cabrera went on to synonym (zoology), synonymize it with the gray four-eyed opossum. The American zoologist Alfred Gardner and later the American mammalogist Philip Hershkovitz would synonymize this species with Anderson's four-eyed opossum. It was recognized as a distinct species in 2020 following a study of the analysis of the cytochrome b of the holotype and other specimens. This analysis determined its closest relatives to be the dark four-eyed opossum and the Philander vossi, northern four-eyed opossum. This species is recognized by the American Society of Mammalogists, but not by the IUCN. Description The back, muzzle, sides, head, and outer part of the legs of this species is greyi ...

Oldfield Thomas
Michael Rogers Oldfield Thomas (21 February 1858 – 16 June 1929) was a British zoologist. Career Thomas worked at the Natural History Museum, London, Natural History Museum on mammals, describing about 2,000 new species and subspecies for the first time. He was appointed to the museum secretary's office in 1876, transferring to the zoological department in 1878. In 1891, Thomas married Mary Kane, daughter of Sir Andrew Clark, 1st Baronet, Sir Andrew Clark, heiress to a small fortune, which gave him the finances to hire mammal collectors and present their specimens to the museum. He also did field work himself in Western Europe and South America. His wife shared his interest in natural history, and accompanied him on collecting trips. In 1896, when William Henry Flower took control of the department, he hired Richard Lydekker to rearrange the exhibitions, allowing Thomas to concentrate on these new specimens. Thomas viewed his taxonomy efforts from the scope of British impe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Opossums
Opossums () are members of the marsupial order Didelphimorphia () endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 126 species in 18 genera. Opossums originated in South America and entered North America in the Great American Interchange following the connection of North and South America in the late Cenozoic. The Virginia opossum is the only species found in the United States and Canada. It is often simply referred to as an opossum; in North America, it is commonly referred to as a possum (; sometimes rendered as ''possum'' in written form to indicate the dropped "o"). The Australasian arboreal marsupials of suborder Phalangeriformes are also called possums because of their resemblance to opossums, but they belong to a different order. The opossum is typically a nonaggressive animal and almost never carries the virus that causes rabies. Etymology The word ''opossum'' is derived from the Powhatan language and was first recorded ...

Type Locality (biology)
In biology, a type is a particular wikt:en:specimen, specimen (or in some cases a group of specimens) of an organism to which the scientific name of that organism is formally associated. In other words, a type is an example that serves to anchor or centralizes the defining features of that particular taxon. In older usage (pre-1900 in botany), a type was a taxon rather than a specimen. A taxon is a scientifically named grouping of organisms with other like organisms, a set (mathematics), set that includes some organisms and excludes others, based on a detailed published description (for example a species description) and on the provision of type material, which is usually available to scientists for examination in a major museum research collection, or similar institution. Type specimen According to a precise set of rules laid down in the International Code of Zoological Nomenclature (ICZN) and the ''International Code of Nomenclature for algae, fungi, and plants'' (ICN), the ...

Marmosops Juninensis
The Junin slender opossum (''Marmosops juninensis'') is a species of South American opossum in the family Didelphidae. It is known only from the valley of the Chanchamayu in Peru (a range that includes Junín Region) where it lives in Andean montane forest Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures lapse rate, fall as elevation increases, causing the ecosystem to stratify. This stratification is ...s at elevations between 1460 and 2200 m. The species is threatened by destruction of its forest habitat as the area under cultivation in the region increases.

Sympatry
In biology, two closely related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter each other. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not shared ranges and ...

Department Of Junín
Junín () is a Departments of Peru, department and Political division of Peru, region in the central highland (geography), highlands and westernmost Peruvian Amazon. Its capital is Huancayo. Geography The region has a very heterogeneous topography. The western cordillera, range located near the border with the Lima Region, has snowy and ice-covered peaks. On the east, there are high glacier valleys which end up in high plateaus (''Altiplano''). Among them is the Junín Plateau that is located between the cities of La Oroya and Cerro de Pasco. The Mantaro Valley becomes wider before Jauja up to the limit with the Huancavelica Region. This area concentrates a large share of the region's population. Towards the east, near the jungle, there is an abundance of narrow and deep canyons, with highly inclined hillsides, covered by woods under low-lying clouds. The Waytapallana mountain range is located in the south central area of the region. This range holds a great fault which is ...

Department Of Ayacucho
Ayacucho (), known as Huamanga from its creation in 1822 until 1825, is a department and region of Peru, located in the south-central Andes of the country. Its capital is the city of Ayacucho. The region was one of the hardest hit in the 1980s during the guerrilla war waged by Shining Path known as the internal conflict in Peru. A referendum was held on 30 October 2005, in order to decide whether the department would merge with the departments of Ica and Huancavelica to form the new Ica-Ayacucho-Huancavelica Region, as part of the decentralization process in Peru. The proposal failed and no merger was carried out. Political division The department is divided into 11 provinces (, singular: ''provincia''), which are composed of 111 districts (''distritos'', singular: ''distrito''). Provinces The provinces, with their capitals in parentheses, are: # Cangallo (Cangallo) # Huamanga (Ayacucho) # Huanca Sancos (Huanca Sancos) # Huanta (Huanta) # La Mar ( San Miguel) # Lucana ...

Departments Of Peru
According to the ''Organic Law of Regional Governments'', the regions () are, with the departments, the first-level semi autonomous administrative subdivisions of Peru. Since its 1821 independence, Peru had been divided into departments (Regions) Peru’s 24 departments each have a regional government and legislature responsible for administration, economic planning, and public services. These governments operate with autonomy while still coordinating with national authorities. Each department is led by a regional governor, who is elected by popular vote for a four-year term. The governor is responsible for implementing regional policies, managing budgets, and overseeing infrastructure projects. Supporting the governor is the regional legislative council, composed of elected representatives from different provinces within the department. This council approves budgets, monitors public investments, and ensures government accountability. Each department is further divided into ...

Andes Mountains
The Andes ( ), Andes Mountains or Andean Mountain Range (; ) are the longest continental mountain range in the world, forming a continuous highland along the western edge of South America. The range is long and wide (widest between 18°S and 20°S latitude) and has an average height of about . The Andes extend from south to north through seven South American countries: Argentina, Chile, Bolivia, Peru, Ecuador, Colombia, and Venezuela. Along their length, the Andes are split into several ranges, separated by intermediate depressions. The Andes are the location of several high plateaus—some of which host major cities such as Quito, Bogotá, Cali, Arequipa, Medellín, Bucaramanga, Sucre, Mérida, El Alto, and La Paz. The Altiplano Plateau is the world's second highest after the Tibetan Plateau. These ranges are in turn grouped into three major divisions based on climate: the Tropical Andes, the Dry Andes, and the Wet Andes. The Andes are the highest mountain r ...
