Red Rock Hare
The red rock hares are the four species in the genus ''Pronolagus''. They are African lagomorphs of the family Leporidae. Taxonomic history Species in this genus had previously been classified in the genus ''Lepus'', as done by J. E. Gray, or in ''Oryctolagus'', as done by Charles Immanuel Forsyth Major. The genus ''Pronolagus'' was proposed by Marcus Ward Lyon, Jr. in 1904, based on a skeleton that had been labeled ''Lepus crassicaudatus'' . Lyon later acknowledged the work of Oldfield Thomas and Harold Schwann, which argued that particular specimen belonged to a species they named ''Pronolagus ruddi'' ; he wrote that the type species "should stand as ''Pronolagus crassicaudatus'' (not ) = ''Pronolagus ruddi'' ". ''P. ruddi'' is no longer regarded as its own species, but rather a subspecies of ''P. crassicaudatus''. In the 1950s, John Ellerman and Terence Morrison-Scott classified ''Poelagus'' as a subgenus of ''Pronolagus''. B. G. Lundholm regarded ''P. randensis'' as a sy ...

Karotype
A karyotype is the general appearance of the complete set of metaphase chromosomes in the cells of a species or in an individual organism, mainly including their sizes, numbers, and shapes. Karyotyping is the process by which a karyotype is discerned by determining the chromosome complement of an individual, including the number of chromosomes and any abnormalities. A karyogram or idiogram is a graphical depiction of a karyotype, wherein chromosomes are organized in pairs, ordered by size and position of centromere for chromosomes of the same size. Karyotyping generally combines light microscopy and photography, and results in a photomicrographic (or simply micrographic) karyogram. In contrast, a schematic karyogram is a designed graphic representation of a karyotype. In schematic karyograms, just one of the sister chromatids of each chromosome is generally shown for brevity, and in reality they are generally so close together that they look as one on photomicrographs as ...

Chromosomes
A chromosome is a long DNA molecule with part or all of the genetic material of an organism. In most chromosomes the very long thin DNA fibers are coated with packaging proteins; in eukaryotic cells the most important of these proteins are the histones. These proteins, aided by chaperone proteins, bind to and condense the DNA molecule to maintain its integrity. These chromosomes display a complex three-dimensional structure, which plays a significant role in transcriptional regulation. Chromosomes are normally visible under a light microscope only during the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, each chromosome is duplicated (S phase), and both copies are joined by a centromere, resulting either in an X-shaped structure (pictured above), if the centromere is located equatorially, or a two-arm structure, if the centromere is located distally. The joined copies are now called sis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Henry Lyster Jameson
Henry Paul William Lyster Jameson (1875, Louth – 26 February 1922, West Mersea) was a zoologist, who studied pearl-formation. He also made contributions to speleology and encouraged the study of psychology in adult education. Life H. Lyster Jameson was born in Louth the son of Paul Lyster Jameson, the rector of Killincoole. He was educated at Trinity College Dublin. In 1895 he explored the Marble Arch Caves with Édouard-Alfred Martel, and was the first to describe fauna in the Mitchelstown Cave. After a year at the Royal College of Science in London, Jameson studied zoology under Otto Bütschli at the University of Heidelberg, writing his dissertation (1898) on , a species of spoon worms. Put in charge of a pearling station in British New Guinea, he studied the causes of pearl-formation. He continued this research at the Lancashire Sea Fisheries Station in Piel Island, Barrow-in-Furness, developing the parasitic theory of pearl-formation in the common sea mussel ...

Hard Palate
The hard palate is a thin horizontal bony plate made up of two bones of the facial skeleton, located in the roof of the mouth. The bones are the palatine process of the maxilla and the horizontal plate of palatine bone. The hard palate spans the alveolar process, alveolar arch formed by the alveolar process that holds the upper teeth (when these are developed). Structure The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone. It forms a partition between the nasal passages and the mouth. On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help facilitate the movement of food backward towards the larynx. This partition is continued deeper into the mouth by a fleshy extension called the soft palate. On the ventral surface of hard palate, some projections or transverse ridges are present which are called as palatine rugae. Function The hard palate is important for feeding and sp ...

Interparietal Bone
An interparietal bone (os interparietale or Inca bone or ''os inca var.'') is a dermal bone situated between the parietal and supraoccipital. It is homologous to the postparietal bones of other animals. In humans, it corresponds to the upper portion of the squama of the occipital bone that lies superior to the highest nuchal line and is completely fused to the supraoccipital. However, in some individuals this portion remains separate from the rest of the occipital bone throughout life. In such cases, this separate bone is particularly referred as Inca bone. Inca bones in humans were first found in the skulls of contemporary indigenous peoples of the southern Andes as well as in those of mummies of the Inca civilization. Although the Inca bone was originally encountered as a variation in South American and Latin American cranial remains, the variation occurs in people from all geographic regions of the world and is by no means indicative of South/Latin American origin.

Hewitt's Red Rock Hare
The Hewitt's red rock hare (''Pronolagus saundersiae'') is a species of mammal in the family Leporidae. It had previously been classified as a subspecies of '' Pronolagus rupestris'', but is now regarded as its own species due to differences in morphology and genetic differences in cytochrome b, and 12S rRNA. Taxonomic history This species was named by John Hewitt (1880–1961), who was the director of the Albany Museum, South Africa. Hewitt originally described this taxon as a subspecies of ''Pronolagus crassicaudatus'' in his 1927 description. Its type locality Type locality may refer to: * Type locality (biology) * Type locality (geology) See also * Local (other) * Locality (other) {{disambiguation ... was Grahamstown. He described this taxon based and skulls from Albany district, collected by Enid Saunders and Frank Bowker; the species is named after Saunders.

Smith's Red Rock Hare
Smith's red rockhare, Smith's red rock hare or Smith's red rock rabbit (''Pronolagus rupestris'') is a species of mammal in the family Leporidae (rabbits and hares), and is the smallest member of the genus ''Pronolagus''. The upperparts and gular collar are reddish brown in colour. It has warm, brown, grizzled, thicker hairs at the back of the body, and white to tawny, thinner underfur. It is native to Africa, found in parts of Kenya (Rift Valley), Lesotho, Malawi, Namibia, South Africa (Northern Cape, Free State, and North West), Tanzania, Zambia and Zimbabwe. It is a folivore, and usually forages on grasses (such as sprouting grass), shrubs and herbs. It breeds from September to February, and the female litters one or two offspring. The young leave the nest at three years of age. In 1996, it was rated as a species of least concern on the IUCN Red List of Endangered Species.

Jameson's Red Rock Hare
Jameson's red rock hare (''Pronolagus randensis'') is a leporid found only on the continent of Africa, mostly in the southern portion of the continent. Zimbabwe and Namibia are thought to have the largest populations of the red rock hare and it is said to be found throughout both countries. South Africa has a population of this red rock hare but it is only found in the northwestern part of the country. Botswana also has a population in the Tswapong Hills. Habitat Jameson's red rock hare is found in very rocky environments, this is where it gets its name. This red rock hare is found on the rocky slopes of mountainous regions of the southern African continent. It is also found in grassy or bushy areas on or around these mountains and it uses them as its shelter during resting periods and sleep. Description This species has a fine, silky fur which is grizzled rufous-brown on the upper parts of the body. It has a whitish chin and slightly lighter fur on the ventrum. The s ...
