Kuril Islands Bobtail
The Kurilian Bobtail is a cat breed (or breed group, depending on registry) originating from the (disputed) Russian Kuril Islands, as well as Sakhalin Island and the Kamchatka peninsula of Russia. Short- or long-haired, it has a semi-cobby body type and a distinct short, fluffy tail. The back is slightly arched with hind legs longer than the front, similar to those of the Manx. The breed is also called the Kuril Islands Bobtail, Kuril Bobtail (both often misspelled "Kurile") and Curilsk Bobtail, and may be referred to without "Bobtail". It is sometimes also spelled Kurilean. The original short-haired variant is a natural breed, known on the islands for over 200 years. As selectively bred pets, they have been popular in Russia and to some extent other parts of Europe, especially for their rodent-hunting abilities, since the middle of the 20th century, but remained rare in North America . Kurilians are recognized as a breed group of a pair related short- and emi-ong-haired br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cat Breed
The following list of cat breeds includes only domestic cat breeds and domestic and wild hybrids. The list includes established breeds recognized by various cat registries, new and experimental breeds, landraces being established as standardized breeds, distinct domestic populations not being actively developed and lapsed (extinct) breeds. As of 2019, The International Cat Association (TICA) recognizes 73 standardized breeds, the Cat Fanciers' Association (CFA) recognizes 45, and the Fédération Internationale Féline (FIFe) recognizes 48. Inconsistency in a breed classification and naming among registries means that an individual animal may be considered different breeds by different registries (though not necessarily eligible for registry in them all, depending on its exact ancestry). For example, TICA's Himalayan is considered a colorpoint variety of the Persian by the CFA, while the Javanese (or Colorpoint Longhair) is a color variation of the Balinese in both the TICA and ...

Eurasia
Eurasia (, ) is the largest continental area on Earth, comprising all of Europe and Asia. Primarily in the Northern and Eastern Hemispheres, it spans from the British Isles and the Iberian Peninsula in the west to the Japanese archipelago and the Russian Far East to the east. The continental landmass is bordered by the Atlantic Ocean and Africa to the west, the Pacific Ocean to the east, the Arctic Ocean to the north, and by Africa, the Mediterranean Sea, and the Indian Ocean to the south. The division between Europe and Asia as two continents is a historical social construct, as many of their borders are over land; thus, in some parts of the world, Eurasia is recognized as the largest of the six, five, or four continents on Earth. In geology, Eurasia is often considered as a single rigid megablock. However, the rigidity of Eurasia is debated based on paleomagnetic data. Eurasia covers around , or around 36.2% of the Earth's total land area. It is also home to the lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cat Breeds Originating In Japan
The cat (''Felis catus'') is a domestic species of small carnivorous mammal. It is the only domesticated species in the family Felidae and is commonly referred to as the domestic cat or house cat to distinguish it from the wild members of the family. Cats are commonly kept as house pets but can also be farm cats or feral cats; the feral cat ranges freely and avoids human contact. Domestic cats are valued by humans for companionship and their ability to kill rodents. About 60 cat breeds are recognized by various cat registries. The cat is similar in anatomy to the other felid species: they have a strong flexible body, quick reflexes, sharp teeth, and retractable claws adapted to killing small prey. Their night vision and sense of smell are well developed. Cat communication includes vocalizations like meowing, purring, trilling, hissing, growling, and grunting as well as cat-specific body language. Although the cat is a social species, they are a solitary hunter. As a pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pom-pom
A pom-pom – also spelled pom-pon, pompom or pompon – is a decorative ball or tuft of fibrous material. The term may refer to large tufts used by cheerleaders, or a small, tighter ball attached to the top of a hat, also known as a bobble or toorie. Pom-poms may come in many colours, sizes, and varieties and are made from a wide array of materials, including wool, cotton, paper, plastic, thread, glitter and occasionally feathers. Pom-poms are shaken by cheerleaders, pom or dance teams, and sports fans during spectator sports. Spelling and etymology *'' Webster's Third New International Dictionary'' (1961) gives the spelling as "pompon." *The ''New Oxford American Dictionary'' (third edition, 2010) gives the spelling as "pom-pom." *The ''American Heritage Dictionary of the English Language'' (5th edition, 2011) gives the spelling as "pompom" or "pompon." *''Webster's New World College Dictionary'' (fourth edition) gives the spelling as "pompom."

Siberian Cat
The Siberian is a centuries-old landrace (natural variety) of domestic cat in Russia and recently developed as a formal breed with standards promulgated the world over since the late 1980s. Siberians vary from medium to medium-large in size. The formal name of the breed is Siberian Forest Cat, but it is typically referred to as the Siberian or Siberian cat. Another formal breed name is the Moscow Semi-Longhair. The cat is an ancient breed that is now believed to be ancestral to all modern long-haired cats. The cat has similarities with the Norwegian forest cat, to which it is likely closely related. It is a natural breed from Siberia and the national cat of Russia. While it began as a landrace, it is selectively bred and pedigreed today in at least seven major cat fancier and breeder organizations. The colorpoint variant of the breed is called the Neva Masquerade by some registries, including ''Fédération Internationale Féline'' (FIFé). The Siberian is often called hypoal ...

Founder Effect
In population genetics, the founder effect is the loss of genetic variation that occurs when a new population is established by a very small number of individuals from a larger population. It was first fully outlined by Ernst Mayr in 1942, using existing theoretical work by those such as Sewall Wright. As a result of the loss of genetic variation, the new population may be distinctively different, both genotypically and phenotypically, from the parent population from which it is derived. In extreme cases, the founder effect is thought to lead to the speciation and subsequent evolution of new species. In the figure shown, the original population has nearly equal numbers of blue and red individuals. The three smaller founder populations show that one or the other color may predominate (founder effect), due to random sampling of the original population. A population bottleneck may also cause a founder effect, though it is not strictly a new population. The founder effect occu ...

Island Biogeography
Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands. Under either name it is now used in reference to any ecosystem (present or past) that is isolated due to being surrounded by unlike ecosystems, and has been extended to mountain peaks, seamounts, oases, fragmented forests, and even natural habitats isolated by human land development. The field was started in the 1960s by the ecologists Robert H. MacArthur and E. O. Wilson, who coined the term ''island biogeography'' in their inaugural contribution to Princeton's Monograph in Population Biology series, which attempted to predict the number of species that would exist on a newly created island.

Genetic Diversity
Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species. It is distinguished from '' genetic variability'', which describes the tendency of genetic characteristics to vary. Genetic diversity serves as a way for populations to adapt to changing environments. With more variation, it is more likely that some individuals in a population will possess variations of alleles that are suited for the environment. Those individuals are more likely to survive to produce offspring bearing that allele. The population will continue for more generations because of the success of these individuals. The academic field of population genetics includes several hypotheses and theories regarding genetic diversity. The neutral theory of evolution proposes that diversity is the result of the accumulation of neutral substitutio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mutation
In biology, a mutation is an alteration in the nucleic acid sequence of the genome of an organism, virus, or extrachromosomal DNA. Viral genomes contain either DNA or RNA. Mutations result from errors during DNA replication, DNA or viral replication, mitosis, or meiosis or other types of DNA repair#DNA damage, damage to DNA (such as pyrimidine dimers caused by exposure to ultraviolet radiation), which then may undergo error-prone repair (especially microhomology-mediated end joining), cause an error during other forms of repair, or cause an error during replication (DNA repair#Translesion synthesis, translesion synthesis). Mutations may also result from Insertion (genetics), insertion or Deletion (genetics), deletion of segments of DNA due to mobile genetic elements. Mutations may or may not produce detectable changes in the observable characteristics (phenotype) of an organism. Mutations play a part in both normal and abnormal biological processes including: evolution, cancer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Karelian Bobtail
The Karelian Bobtail is a breed of cat that originated in the Lake Ladoga region of the Republic of Karelia, Russia. History The breed was first recognised by the World Cat Federation in 1994. Characteristics Karelian Bobtails can be either short-haired or long-haired. The tail varies from 4 to 13 cm in length, and has longer hair than that of the body. Unlike similar breeds such as the Kurilian Bobtail, the bobbed tail is recessive In genetics, dominance is the phenomenon of one variant (allele) of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome. The first variant is termed dominant and t .... All colours except cinnamon, chocolate, fawn and lilac are acceptable; all patterns are acceptable also except for colorpointing. The Karelian Bobtail has a soft undercoat and a glossy and thick top coat. References Cat breeds originating in Russia Cat breeds {{felid-stub ...
