Rabbit And Hare Mascots
Rabbits are small mammals in the family (biology), family Leporidae (which also includes the hares), which is in the order (biology), order Lagomorpha (which also includes pikas). They are familiar throughout the world as a small herbivore, a prey animal, a domesticated form of livestock, and a pet, having a widespread effect on Ecology, ecologies and cultures. The most widespread rabbit Genus, genera are ''Oryctolagus'' and ''Sylvilagus''. The former, ''Oryctolagus'', includes the European rabbit, ''Oryctolagus cuniculus'', which is the ancestor of the hundreds of List of rabbit breeds, breeds of domestic rabbit and has been introduced on every continent except Antarctica. The latter, ''Sylvilagus'', includes over 13 wild rabbit species, among them the cottontail rabbit, cottontails and tapetis. Wild rabbits not included in ''Oryctolagus'' and ''Sylvilagus'' include several species of limited Species distribution, distribution, including the pygmy rabbit, volcano rabbit, and ...

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''Ēṓs'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hare
Hares and jackrabbits are mammals belonging to the genus ''Lepus''. They are herbivores and live Solitary animal, solitarily or in pairs. They nest in slight depressions called forms, and their young are precociality, able to fend for themselves shortly after birth. The genus includes the largest Lagomorpha, lagomorphs. Most are fast runners with long, powerful hind legs, and large ears that dissipate body heat. Hare species are native to Africa, Eurasia and North America. A hare less than one year old is called a "leveret". Members of the ''Lepus'' genus are considered true hares, distinguishing them from rabbits which make up the rest of the Leporidae family. However, there are five leporid species with "hare" in their common names which are not considered true hares: the hispid hare (''Caprolagus hispidus''), and four species known as red rock hares (''Pronolagus''). Conversely, several ''Lepus'' species are called "jackrabbits", but classed as hares rather than rabbits. The p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano Rabbit
The volcano rabbit (''Romerolagus diazi'') (), also known as the teporingo or zacatuche, is a small mammal in the family Leporidae that resides on the slopes of volcanoes in Mexico. It is the only species in the genus ''Romerolagus''. It has small rounded ears, short legs, a large forehead, and short, thick fur. Adult rabbits can weigh from . The volcano rabbit lives in groups of 2 to 5 animals in burrows (underground nests) and runways among bunchgrasses. Up to 3 young are produced per litter, born in nests formed from shallow depressions in the ground lined with fur and plant matter. Uniquely among the rabbits, the volcano rabbit emits high-pitched sounds to warn other rabbits of danger, a habit common in the related pikas. It is awake and most active in the evening and early morning. Populations have been estimated as approximately 7,000 adult individuals over their entire range. Human developments surrounding the volcano rabbit's habitat, including overgrazing, hunting, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pygmy Rabbit
The pygmy rabbit (''Sylvilagus idahoensis'') is a rabbit species native to the United States. It is the only native rabbit species in North America to dig its own burrow. The pygmy rabbit differs significantly from species within either the '' Lepus'' (hare) or '' Sylvilagus'' (cottontail) genera, and was once considered to be within the genus '' Brachylagus'', which includes one extinct species. One isolated population, the Columbia Basin pygmy rabbit, is listed as an endangered species by the U.S. Federal government, though the International Union for Conservation of Nature lists the species as lower risk. Taxonomy The pygmy rabbit was first described by Clinton Hart Merriam in 1891, as ''Lepus idahoensis''; the type specimen, in winter pelage, had been collected in the Pahsimeroi Valley the previous autumn. In 1900, Gerrit S. Miller, Jr. erected the new subgenus '' Brachylagus'' for the pygmy rabbit; ''Brachylagus'' has since been elevated to the rank of genus. Historica ...

Species Distribution
Species distribution, or species dispersion, is the manner in which a biological taxon is spatially arranged. The geographic limits of a particular taxon's distribution is its range, often represented as shaded areas on a map. Patterns of distribution change depending on the scale at which they are viewed, from the arrangement of individuals within a small family unit, to patterns within a population, or the distribution of the entire species as a whole (range). Species distribution is not to be confused with biological dispersal, dispersal, which is the movement of individuals away from their center of origin, region of origin or from a population center of high population density, density. Range In biology, the range of a species is the geographical area within which that species can be found. Within that range, distribution is the general structure of the species population, while dispersion is the variation in its population density. Range is often described with the foll ...

Tapeti
The common tapeti (''Sylvilagus brasiliensis''), also known as the Brazilian cottontail, forest cottontail, or (formerly) simply tapeti is a species of cottontail rabbit. It is small to medium-sized with a small, dark tail, short hind feet, and short ears. As traditionally defined, its range extends from southern Mexico to northern Argentina, but this includes several distinctive population that have since been split into separate species. Under this narrower definition, the true common tapeti only occurs in the Atlantic Rainforest of coastal northeastern Brazil and it is classified as "Endangered" by the IUCN. The American Society of Mammalogists concurs, but also tentatively classifies several distinct populations that have not yet received proper species names into ''S. brasiliensis'', and thus considers it to range from Venezuela south to Argentina. Taxonomy The species was first described scientifically by Carl Linnaeus in the 10th edition of Systema Naturae, published in ...

Cottontail Rabbit
Cottontail rabbits are in the ''Sylvilagus'' genus, which is in the family Leporidae. They are found in the Americas. Most ''Sylvilagus'' species have stub tails with white undersides that show when they retreat, giving them their characteristic name. However, this feature is not present in all ''Sylvilagus'', nor is it unique to the genus. However their fur ranges from brown to gray and changes throughout the year, depending on the season. The genus is widely distributed across North America, Central America, and northern and central South America, though most species are confined to particular regions. Most species live in nests called forms, and all have altricial young. They often live on the edges of fields, farms, and other open spaces far from highly populated areas. But sometimes they make their nests in yards and parks near more people. An adult female averages three litters per year, which can be born in any season. Occurrence and litter size depend on several factors ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antarctica
Antarctica () is Earth's southernmost and least-populated continent. Situated almost entirely south of the Antarctic Circle and surrounded by the Southern Ocean (also known as the Antarctic Ocean), it contains the geographic South Pole. Antarctica is the fifth-largest continent, being about 40% larger than Europe, and has an area of . Most of Antarctica is covered by the Antarctic ice sheet, with an average thickness of . Antarctica is, on average, the coldest, driest, and windiest of the continents, and it has the highest average elevation. It is mainly a polar desert, with annual Climate of Antarctica#Precipitation, precipitation of over along the coast and far less inland. About 70% of the world's freshwater reserves are frozen in Antarctica, which, if melted, would raise global sea levels by almost . Antarctica holds the record for the Lowest temperature recorded on Earth, lowest measured temperature on Earth, . The coastal regions can reach temperatures over in the ...

Domestic Rabbit
The domestic rabbit (''Oryctolagus cuniculus domesticus'') is the domestication, domesticated form of the European rabbit, a member of the lagomorph order. A male rabbit is known as a ''buck,'' a female as a ''doe,'' and a young rabbit as a ''kit''. There are hundreds of List of rabbit breeds, rabbit breeds, originating from all over the world. Rabbits were first domesticated and used for their Rabbit#As food and clothing, food and fur by Ancient Rome, the Romans. Rabbits may be housed inside, but the idea of the domestic rabbit as a house companion, a so-called ''house rabbit'' (similar to a house cat), was only strongly promoted starting with publications in the 1980s. Rabbits can be trained to use a litter box and taught to Animal training, come when called, but they require exercise and can damage a house or injure themselves if it has not been suitably prepared, based on their innate need to chew.

List Of Rabbit Breeds
As of 2017, there were at least 305 breeds of the domestic rabbit in 70 countries around the world raised for in the Agriculture, agricultural practice of Selective breeding, breeding and raising domestic rabbits as livestock for their value in meat, fur, wool, education, Scientific method, scientific research, entertainment and companionship in cuniculture. A rabbit breed is a distinct strain created through selective breeding (or occasionally natural selection) for specific characteristics, including size, fur, body type, color, feed conversion ratio, et cetera. Organizations such as the American Rabbit Breeders Association (ARBA) and the British Rabbit Council (BRC) have standards for the desired qualities of their respective recognized breeds. Each rabbit breed is considered to benefit when a reputable breeder strives to emulate the perfect example for the breed, defined by the individual breed standard by which it may be judged.

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Ecology
Ecology () is the natural science of the relationships among living organisms and their Natural environment, environment. Ecology considers organisms at the individual, population, community (ecology), community, ecosystem, and biosphere levels. Ecology overlaps with the closely related sciences of biogeography, evolutionary biology, genetics, ethology, and natural history. Ecology is a branch of biology, and is the study of abundance (ecology), abundance, biomass (ecology), biomass, and distribution of organisms in the context of the environment. It encompasses life processes, interactions, and adaptations; movement of materials and energy through living communities; ecological succession, successional development of ecosystems; cooperation, competition, and predation within and between species; and patterns of biodiversity and its effect on ecosystem processes.
