Cavia Anolaimae
''Cavia anolaimae'' is a guinea pig species from South America. It is found in Colombia near Bogotá. It is believed to be a feral offshoot of the domestic guinea pig, ''Cavia porcellus'', and is often treated as a synonym of ''C. porcellus'', but Zúñiga et al. (2002), based on morphologic characters, recognized them as different species. According to the molecular analysis of Dunnum and Salazar (2010) ''C. anolaimae'' is a subspecies In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morpholog ... of '' Cavia aperea'', ''C. aperea anolaimae'', and a possible synonymous of '' C. a. guianae'' .

Cavia
''Cavia'' is a genus in the subfamily Caviinae that contains the rodents commonly known as the guinea pigs or cavies. The best-known species in this genus is the domestic guinea pig, ''Cavia porcellus'', a meat animal in South America and a common household pet outside that continent. Characteristics General characteristics The true guinea pigs are medium-sized rodents. They reach a head-body length of 20 to 35 centimeters (8 to 14 inches) and a weight of 500 to a maximum of 1,000 grams. The largest species of the genus is the greater guinea pig (''Cavia magna''). The species are very similar in habit and appearance, the long and relatively rough fur is usually grayish or brown to reddish-brown in color. The coloring can be variable, especially in species with a large distribution area and several subspecies. The head is relatively large in relation to the body, the eyes are large and the ears are small. The legs are short and strong, the front feet have four toes and the h ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Feral
A feral (; ) animal or plant is one that lives in the wild but is descended from domesticated individuals. As with an introduced species, the introduction of feral animals or plants to non-native regions may disrupt ecosystems and has, in some cases, contributed to extinction of indigenous species. The removal of feral species is a major focus of island restoration. Animals A feral animal is one that has escaped from a domestic or captive status and is living more or less as a wild animal, or one that is descended from such animals. Other definitions include animals that have changed from being domesticated to being wild, natural, or untamed. Some common examples of animals with feral populations are horses, dogs, goats, cats, rabbits, camels, and pigs. Zoologists generally exclude from the feral category animals that were genuinely wild before they escaped from captivity: neither lions escaped from a zoo nor the white-tailed eagles re-introduced to the UK are regarded ...

Guinea Pig
The guinea pig or domestic guinea pig (''Cavia porcellus''), also known as the cavy or domestic cavy ( ), is a species of rodent belonging to the genus ''Cavia'', family Caviidae. Animal fancy, Breeders tend to use the name "cavy" for the animal, but "guinea pig" is more commonly used in scientific and laboratory contexts. Despite their name, guinea pigs are not native to Guinea (region), Guinea, nor are they closely related to suidae, pigs. Instead, they originated in the Andes region of South America, where wild guinea pigs can still be found today. Studies based on biochemistry and DNA Hybrid (biology), hybridization suggest they are domestication, domesticated animals that do not exist naturally in the wild, but are descendants of a closely related cavy species such as ''Montane guinea pig, C. tschudii''. Originally, they were domesticated as livestock (source of meat) in the Andean region and are still consumed in some parts of the world. In Western society, the guin ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Cavia Aperea
The Brazilian guinea pig (''Cavia aperea'') (''preá'' in Portuguese) is a wild guinea pig species found in Argentina, Brazil, Bolivia, Colombia, Ecuador, Guyana, Paraguay, Uruguay and Venezuela. ''Cavia aperea'' has been successfully mated to the domestic guinea pig, ''Cavia porcellus'', though many females become infertile in successive generations. Brazilian guinea pigs are mainly diurnal animals and are narrower and longer than domesticated guinea pigs. Description This is a medium-sized guinea pig with an adult length of about and a weight of . The tail, at around 2.4 mm, is almost non-existent. The dorsal fur is dark olive-brown mixed with brown and black, and the underparts are a pale grey or yellowish-grey. Its karyotype has 2n = 64 and a reportedly variable FN of 116 or 128 for ''C. a. aperea'' and 128 for ''C. a. pamparum''. Distribution The Brazilian guinea pig has a wide distribution in South America at altitudes between above sea level. Its range extends ...

Cavia Guianae
''Cavia guianae'' is a guinea pig species from South America. It is found in southern Venezuela, Guyana, and portions of northern Brazil Brazil, officially the Federative Republic of Brazil, is the largest country in South America. It is the world's List of countries and dependencies by area, fifth-largest country by area and the List of countries and dependencies by population .... Some biologists believe it to be a feral offshoot of the domestic guinea pig, ''Cavia porcellus''; others subsume it under the wild cavy, '' Cavia aperea''. Molecular data collected show there is little genetic differentiation in ''C.a. guianae'' known to be a lowland locality in comparison to ''C. anolaimae'' which are predominantly highland populations.

Endemic Fauna Of Colombia
Endemism is the state of a species being found only 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 also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...
