Zoologist
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the Animal, animal kingdom, including the anatomy, structure, embryology, evolution, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and made use of this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cuscomys Ashaninka
''Cuscomys'' is a genus of rodents found in the Andes of Cusco in southern Peru. These relatively large chinchilla rats are dark grey with a distinct white line running from the crown to the nose. The genus was coined in 1999 when ''C. ashaninka'' was scientifically described,Emmons, L. H. (1999). ''A new genus and species of abrocomid rodent from Peru (Rodentia: Abrocomidae).'' American Museum Novitates 3279: 1-14. but later it was discovered that ''C. oblativus'', a species traditionally placed in the genus ''Abrocoma'', actually belonged in ''Cuscomys''. They are very poorly known, as ''C. ashaninka'' only is known from the holotype, while ''C. oblativus'' usually has been considered extinct, as it was only known from remains found in 1912, buried alongside people in ancient Inca tombs at the Machu Picchu ruins. However, photos of a rodent taken at the ruins in late 2009 likely show this species.Castillo, G. M. (2009). Detectan en Cusco a roedor declarado extinto'. El Comercio ...

Rice Rat
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 class ...

Euryoryzomys Emmonsae
''Euryoryzomys emmonsae'', also known as Emmons' rice rat or Emmons' oryzomys, is a rodent from the Amazon rainforest of Brazil in the genus ''Euryoryzomys'' of the family Cricetidae. Initially misidentified as '' E. macconnelli'' or '' E. nitidus'', it was formally described in 1998. A rainforest species, it may be scansorial, climbing but also spending time on the ground. It lives only in a limited area south of the Amazon River in the state of Pará, a distribution that is apparently unique among the muroid rodents of the region. ''Euryoryzomys emmonsae'' is a relatively large rice rat, weighing , with a distinctly long tail and relatively long, tawny brown fur. The skull is slender and the incisive foramina (openings in the bone of the palate) are broad. The animal has 80 chromosomes and its karyotype is similar to that of other ''Euryoryzomys''. Its conservation status is assessed as "Data Deficient", but deforestation may pose a threat to this species. Taxonomy In ...

Patronym (taxonomy)
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 zoolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monodelphis Gardneri
Gardner's short-tailed opossum (''Monodelphis gardneri'') is a marsupial mammal from South America. It was named in 2012 by Sergio Solari, Víctor Pacheco, Elena Vivar and Louise H. Emmons. They named it after Dr. Alfred L. Gardner who took the first specimen of this species. Description Collected specimen range from 70–100 mm in head-and-body length. The fur has a Prout Brown to Mummy Brown colour with three distinctive black stripes on its back, reaching from between the ears to the base of the tail. The tail is slightly shorter than half of the head-and-body length. This species, although marsupial, has no pouch for its young. Habitat and ecology Gardner's short-tailed opossum inhabits the montane forests on the eastern slopes of the Andes Mountains in Peru. It was found in dense to semi-open forests or even at the edge between forest and an open sphagnum bog in thickets of dense brush and bamboo. It probably is terrestrial and does not climb trees.

Didelphid
Opossums () are members of the marsupial order Didelphimorphia () endemic to the Americas. The largest order of marsupials in the Western Hemisphere, it comprises 93 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. The Virginia opossum is the only species found in the United States and Canada. It is often simply referred to as an opossum, and in North America it is commonly referred to as a possum (; sometimes rendered as ''possum'' in written form to indicate the dropped "o"). Possums should not be confused with the Australasian arboreal marsupials of suborder Phalangeriformes that are also called possums because of their resemblance to the Didelphimorphia. The opossum is typically a nonaggressive animal. Etymology The word ''opossum'' is borrowed from the Powhatan language and was first recorded between 1607 and 1611 by John Smith (as ''opassom'') and W ...

Pithecheirops Otion
The Bornean pithecheirops (''Pithecheirops otion'') is a species of rodent found in Borneo. It is monotypic in the genus ''Pithecheirops''. ''Pithecheirops'' is closely related to the genus ''Pithecheir'', and the name is derived from ''Pithecheir'' and the Greek ''ops'', meaning "resembling". The only known example of this species was caught in the Danum Valley Field Centre in Sabah, north Borneo, at approximately 150 m. Description It is similar to species in the genus ''Pithecheir'', both having long, dense, soft fur and broad feet. The species is distinguished by the appearance of the inner ear bones and auditory bulla. Habitat It was found in "dense viny roadside secondary brush on an abandoned logging road". The dominant habitat of the area is lowland dipterocarp forest.

Oecomys Sydandersoni
''Oecomys sydandersoni'' is an arboreal species of rodent in the genus ''Oecomys''. It lives in forest patches in a small area in eastern Bolivia. It is a medium-sized species, weighing about , with mostly grayish and brownish fur and short and broad hindfeet with well-developed pads. First collected in 1964, it was formally described in 2009. The species may be most closely related to '' O. concolor'' and '' O. mamorae'', which are distributed further north and south in South America. Among other characters, the three share a particular arrangement of the arteries of the head. Virtually nothing is known of its biology. Taxonomy An American Museum of Natural History expedition led by Sydney Anderson collected the first three specimens of ''Oecomys sydandersoni'' in 1964 and 1965.Carleton et al., 2009, p. 19 The material was mentioned in passing in a report on the chiggers of the regionBrennan, 1970, p. 811 and tentatively identified as '' O. concolor ...
