Red Rock Hare
The red rock hares are the four species of rabbit in the genus ''Pronolagus''. They are lagomorphs of the family Leporidae living in rocky habitats across Africa. Three species are restricted to Southern Africa, while one—Smith's red rock hare (''P. rupestris'')—is found as far north as Kenya. The red rock hares are rufous, dark brown, or reddish-brown-tailed rabbits that vary in size, with some shared physical characteristics being short ears and a lack of an Interparietal bone, interpareital bone. They have 42 chromosomes and are active during the night, feeding only on plants. Breeding results in Litter (zoology), litters of one to two altricial young. The red rock hares have a varied Taxonomy, taxonomic history. Initially described as members of the genus ''Lepus'' or ''Oryctolagus'', the genus ''Pronolagus'' was proposed in 1904 to describe a skeleton of ''Natal red rock hare, Pronolagus crassicaudatus'', which was at that time labeled under the genus ''Lepus''.

Pliocene
The Pliocene ( ; also Pleiocene) is the epoch (geology), epoch in the geologic time scale that extends from 5.33 to 2.58See the 2014 version of the ICS geologic time scale million years ago (Ma). It is the second and most recent epoch of the Neogene Period in the Cenozoic, Cenozoic Era. The Pliocene follows the Miocene Epoch and is followed by the Pleistocene Epoch. Prior to the 2009 revision of the geologic time scale, which placed the four most recent major glaciations entirely within the Pleistocene, the Pliocene also included the Gelasian Stage, which lasted from 2.59 to 1.81 Ma, and is now included in the Pleistocene. As with other older geologic periods, the Stratum, geological strata that define the start and end are well-identified but the exact dates of the start a ...

Chromosome
A chromosome is a package of DNA containing part or all of the genetic material of an organism. In most chromosomes, the very long thin DNA fibers are coated with nucleosome-forming packaging proteins; in eukaryotic cells, the most important of these proteins are the histones. Aided by chaperone proteins, the histones bind to and condense the DNA molecule to maintain its integrity. These eukaryotic chromosomes display a complex three-dimensional structure that has a significant role in transcriptional regulation. Normally, chromosomes are 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 stage occurs, each chromosome is duplicated ( S phase), and the two copies are joined by a centromere—resulting in either an X-shaped structure if the centromere is located equatorially, or a two-armed structure if the centromere is located distally; the jo ...

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 ...

National Park
A national park is a nature park designated for conservation (ethic), conservation purposes because of unparalleled national natural, historic, or cultural significance. It is an area of natural, semi-natural, or developed land that is protected and owned by a government. Although governments hold different standards for national park designation, the conservation of 'wild nature' for posterity and as a symbol of national pride is a common motivation for the continued protection of all national parks around the world. National parks are almost always accessible to the public.Gissibl, B., S. Höhler and P. Kupper, 2012, ''Civilizing Nature, National Parks in Global Historical Perspective'', Berghahn, Oxford Usually national parks are developed, owned and managed by national governments, though in some countries with federal government, federal or Devolution, devolved forms of government, "national parks" may be the responsibility of subnational, regional, or local authorities.

Protected Area
Protected areas or conservation areas are locations which receive protection because of their recognized natural or cultural values. Protected areas are those areas in which human presence or the exploitation of natural resources (e.g. firewood, non-timber forest products, water, ...) is limited. The term "protected area" also includes marine protected areas and transboundary protected areas across multiple borders. As of 2016, there are over 161,000 protected areas representing about 17 percent of the world's land surface area (excluding Antarctica). For waters under national jurisdiction beyond inland waters, there are 14,688 Marine Protected Areas (MPAs), covering approximately 10.2% of coastal and marine areas and 4.12% of global ocean areas. In contrast, only 0.25% of the world's oceans beyond national jurisdiction are covered by MPAs. In recent years, the 30 by 30 initiative has targeted to protect 30% of ocean territory and 30% of land territory worldwide by 2030; this ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Least-concern Species
A least-concern species is a species that has been evaluated and categorized by the International Union for Conservation of Nature (IUCN) as not being a focus of wildlife conservation because the specific species is still plentiful in the wild. They do not qualify as threatened, near threatened, or (before 2001) conservation dependent. Species cannot be assigned the "Least Concern" category unless they have had their population status evaluated. That is, adequate information is needed to make a direct, or indirect, assessment of its risk of extinction based on its distribution or population status. Evaluation Since 2001 the category has had the abbreviation "LC", following the IUCN 2001 Categories & Criteria (version 3.1). Before 2001 "least concern" was a subcategory of the " Lower Risk" category and assigned the code "LR/lc" or lc. Around 20% of least concern taxa (3261 of 15,636) in the IUCN database still use the code "LR/lc", which indicates they have not been re- ...

Nomen Oblitum
In zoological nomenclature, a ''nomen oblitum'' (plural: ''nomina oblita''; Latin for "forgotten name") is a disused scientific name which has been declared to be obsolete (figuratively "forgotten") in favor of another "protected" name. In its present meaning, the ''nomen oblitum'' came into being with the fourth edition (1999) of the ''International Code of Zoological Nomenclature''. After 1 January 2000, a scientific name may be formally declared to be a ''nomen oblitum'' when it satisfy the following conditions: # No uses as a valid name in a scientific publication are known after 1899 (this criterion is taken on faith). # It is either a senior synonym (there is also a more recent name which applies to the same taxon, and which is in common use) or a senior homonym (it is spelled the same as another name, which is also in valid use). # The preferred junior synonym or homonym is shown to be in wide use, defined as appearing in 25 or more publications in the past 50 years (must ...

Hewitt's Red Rock Hare
Hewitt's red rock hare (''Pronolagus saundersiae'') is a species of rabbit in the family Leporidae found in South Africa, Eswatini, and Lesotho. It is a medium-sized, densely-furred rufous and brown rabbit that behaves similarly to other red rock hares, with a preference for higher elevated rocky habitats. Previously classified as a subspecies of Smith's red rock hare (''Pronolagus rupestris''), it is now regarded as its own species. Like other red rock hares, ''P. saundersiae'' is nocturnal, and is presumed to feed on grasses, herbs, and shrubs. Its breeding patterns are also presumed to be similar to those of other red rock hares, with females producing three to four litters of altricial young each warm season. The species is predated upon by Verreaux's eagle, Cape eagle-owls, and leopards. It is considered a least-concern species by the International Union for Conservation of Nature (IUCN) and is said to be "abundant" throughout its range, despite not being protected by ...

Jameson's Red Rock Hare
Jameson's red rock hare (''Pronolagus randensis'') is a species of hare in the family Leporidae found in rocky habitats in Zimbabwe, Angola, Namibia, South Africa, Botswana, and Mozambique. It is rufous and brown-furred, nocturnal, in length and in weight—slightly smaller than the largest of the red rock hare species, the Natal red rock hare (''P. crassicaudatus''). The species is generally solitary when not breeding or grazing. Jameson's red rock hare feeds only at night. While grazing, it is sometimes seen in small groups feeding upon grasses and fresh shoots. Little is known about its mating behaviour, and its predators are similar to those of other red rock hares. It is classified as a least-concern species by the International Union for Conservation of Nature (IUCN), being abundant in the protected areas its distribution overlaps, but its population is decreasing. Taxonomy and evolution ''Pronolagus randensis'' was first described by and named after Irish zoologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Natal Red Rock Hare
The Natal red rock hare or greater red rock hare (''Pronolagus crassicaudatus'') is a species of mammal in the family Leporidae (rabbits and hares). It has a slightly grizzled, grayish brown head and reddish brown upperparts. The dense fur is thick and rougher than other rock hares. It is endemic to Africa, and found in southeastern provinces of South Africa (Eastern Cape, Mpumalanga, and KwaZulu-Natal), eastern Lesotho, Eswatini (Highveld and Lumbobo), and southern Mozambique (Maputo Province). It is a herbivore, primarily feeding on grass. It breeds throughout the year, and one or two pups are usually born in the summer. It is rated as a species of least concern on the IUCN Red List of Endangered Species. Taxonomy French zoologist Isidore Geoffroy Saint-Hilaire first described the Natal red rock hare in 1832 and classified it in the genus ''Lepus'', giving it the name ''Lepus crassicaudatus''. American mammalogist Marcus Ward Lyon Jr. later place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
