Hylaeamys Laticeps
''Hylaeamys laticeps'', also known as the Atlantic Forest oryzomysMusser and Carleton, 2005 or the large-headed rice rat, is a species of rodent in the family Cricetidae. The rodent is endemic to the Atlantic Forest region of southeastern Brazil. The taxonomic history of ''Hylaeamys laticeps'' has been complex, and the name ''laticeps'' has been used for various members of the genera '' Cerradomys'', '' Euryoryzomys'', '' Transandinomys'' and ''Hylaeamys'' at different times. Until 2006, it was classified in the genus ''Oryzomys ''Oryzomys'' is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America.

Peter Wilhem Lund
Peter Wilhelm Lund (14 June 1801 – 25 May 1880) was a Danish paleontologist, zoologist, and archeologist. He spent most of his life working and living in Brazil. He is considered the father of Brazilian paleontology as well as archaeology. He was the first to describe dozens of species of pre-historic Pleistocene megafauna, including the fabled Saber-toothed cat ''Smilodon populator''. He also made the then ground-breaking discovery that humans co-existed with the long-extinct animal species, something which possibly prompted him to terminate his scientific work. His comprehensive collections are today found at the Danish Natural History Museum in Copenhagen. Early life and education Peter Wilhelm Lund was born into a wealthy family in Copenhagen. He showed an early interest in the natural science and was working towards a career in medicine but following the death of his father, his passion for natural history prompted him instead to opt for that study at the University of ...

Hylaeamys
''Hylaeamys'' is a genus of South American oryzomyine rodents found principally in humid forested areas east of the Andes. The species in this genus have historically been placed in ''Oryzomys''. They are most closely related to ''Euryoryzomys'', ''Transandinomys'', '' Nephelomys'', '' Oecomys'', and ''Handleyomys'', and most closely resemble species of the former two genera. They are distinguished from members of ''Euryoryzomys'' by all-dark or indistinct two-tone tail coloration (as opposed to the distinct two-tone tail coloration of ''Euryoryzomys''), from members of ''Transandinomys'' by having shorter whiskers above their eyes that do not extend posteriorly behind their ears, and in both cases by differences in carotid circulation. The genus is named after ''hylaea'' ("forest" in Greek), the term used by Humboldt for the lowland South American rainforests that are the main habitat of the genus. The genus currently comprises the following species: * '' Hylaeamys acritus'' * ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fauna Of The Atlantic Forest
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is '' funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Fauna Of Brazil
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 s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Of Brazil
Brazil has the largest mammal diversity in the world, with more than 600 described species and more likely to be discovered. According to the International Union for Conservation of Nature, 66 of these species are endangered, and 40% of the threatened taxa belong to the primate group. 658 species are listed. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of near threatened and least concern categories: Infraclass: Metatheria Order: Didelphimorphia * Family: Caluromyidae ** Genus: '' Caluromys'' *** Brown-eared woolly opossum, ''C. lanatus'' LC *** Bare-tailed woolly opossum, ''C. philander'' LC * Family: Didelphidae ** Genus: ''Caluromysiops'' *** Black-shouldered opossum, ''Caluromysiops irrupta'' LC ** Genus: ''Glironia'' *** Bushy-tailed opossum, ' ...

Rodents Of South America
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose incisors ...

Junior Synonym
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia lev ...

Oryzomys
''Oryzomys'' is a genus of semiaquatic rodents in the tribe Oryzomyini living in southern North America and far northern South America. It includes eight species, two of which—the marsh rice rat (''O. palustris'') of the United States and '' O. couesi'' of Mexico and Central America—are widespread; the six others have more restricted distributions. The species have had eventful taxonomic histories, and most species were at one time included in the marsh rice rat; additional species may be recognized in the future. The name ''Oryzomys'' was established in 1857 by Spencer Fullerton Baird for the marsh rice rat and was soon applied to over a hundred species of American rodents. Subsequently, the genus gradually became more narrowly defined until its current contents were established in 2006, when ten new genera were established for species previously placed in ''Oryzomys''. Species of ''Oryzomys'' are medium-sized rats with long, coarse fur. The upperparts are gray ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transandinomys
''Transandinomys'' is a genus of rodents in the tribe Oryzomyini of family Cricetidae. It includes two species—'' T. bolivaris'' and '' T. talamancae''—found in forests from Honduras in Central America south and east to southwestern Ecuador and northwestern Venezuela in northern South America. Until 2006, its members were included in the genus ''Oryzomys'', but phylogenetic analysis showed that they are not closely related to the type species of that genus, and they have therefore been placed in a new genus. They may be most closely related to genera like ''Hylaeamys'' and '' Euryoryzomys'', which contain very similar species. Both species of ''Transandinomys'' have had eventful taxonomic histories. ''Transandinomys bolivaris'' and ''T. talamancae'' are medium-sized, soft-furred rice rats. The upperparts—brownish in ''T. bolivaris'' and reddish in ''T. talamancae''—are much darker than the whitish underparts. Both species are characterized by ver ...

Euryoryzomys
''Euryoryzomys'' is a genus of rodents in the tribe Oryzomyini of family Cricetidae. It includes six species, which are distributed in South America. Until 2006, its members were included in the genus ''Oryzomys'', but they are not closely related to the type species of that genus, and therefore they were placed in a new genus. They are most closely related to genera like ''Hylaeamys'' and ''Transandinomys''; many members of these genera were previously placed in a single species, known as ''Oryzomys capito''. The genus name, ''Euryoryzomys'', combines the name "''Oryzomys''" with the Ancient Greek Ancient Greek includes the forms of the Greek language used in ancient Greece and the ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Dark Ages (), the Archaic p ... word ''eurus'' "broad", referring to the broad range in distribution of the genus.

Cerradomys
''Cerradomys'' is a genus of oryzomyine rodents from eastern Bolivia, Paraguay, and central Brazil found in cerrado, Caatinga and Gran Chaco habitats. The species in this genus have historically been placed in ''Oryzomys'', but according to cladistic research, they are not more closely related to the type species of ''Oryzomys'' than species in some other genera are. Its sister group may be a clade of oryzomyines living in open or aquatic habitats, comprising, among others, ''Aegialomys'', ''Nectomys'' and ''Sigmodontomys''. '' Sooretamys angouya'', also formerly in ''Oryzomys'', is another relative; it has been placed in the same group as the species of ''Cerradomys'' in the past. The generic name ''Cerradomys'' is a compound of the word "Cerrado" and the Ancient Greek ''mys'' "mouse" and therefore means "Cerrado mouse". The dorsal pelage is brownish, the ventral pelage, greyish. It has small ears and a relatively long tail. There are crowns of hair on the hindfeet at the bas ...
