Cape Mountain Zebra
The Cape mountain zebra (''Equus zebra zebra'') is a subspecies of mountain zebra that occurs in certain mountainous regions of the Western and Eastern Cape provinces of South Africa. It is the smallest of all existing zebra species and also the most geographically restricted. Although once nearly driven to extinction, the population has now been increased by several conservation methods, and is classified as Vulnerable by the IUCN. Taxonomy The Cape mountain zebra is one of two geographically separated subspecies of the species ''Equus zebra'' (mountain zebra), the other being Hartmann's mountain zebra (''Equus zebra hartmannae''). The Cape mountain zebra was once regarded as a separate species from Hartmann's mountain zebra based on taxonomic evidence, but recent genomic evidence has led to the two populations now being reclassified as subspecies of ''Equus zebra''. Appearance Like all zebra species, the Cape mountain zebra has a characteristic black and white striping pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Mountain Zebra National Park
Mountain Zebra National Park is a national park in the Eastern Cape province of South Africa proclaimed in July 1937 for the purpose of providing a nature reserve for the endangered Cape mountain zebra. History In the early 1930s, the Cape mountain zebra was threatened with extinction. The National Parks Board of Trustees proclaimed a area for the zebra's preservation in 1938 after the purchase of the farm ''Babylons Toren'', Cradock the year before. The mountain zebra population of the park comprised only five stallion (horse), stallions and one mare (horse), mare and was insufficient to expand the population. By 1950 only two stallions remained, and a neighbouring farmer, Mr H L Lombard, improved the breeding pool by donating eleven zebra to the park, five stallions and six mares. By 1964, there were only 25 zebra in the park. At this time, the park's size was increased to and Paul Michau donated six zebra to the park. From then on, the number of zebras increased steadily t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sexual Maturity
Sexual maturity is the capability of an organism to reproduce. In humans it might be considered synonymous with adulthood, but here puberty is the name for the process of biological sexual maturation, while adulthood is based on cultural definitions. Most multicellular organisms are unable to sexually reproduce at birth (animals) or germination (e.g. plants): depending on the species, it may be days, weeks, or years until they have developed enough to be able to do so. Also, certain cues may trigger an organism to become sexually mature. They may be external, such as drought (certain plants), or internal, such as percentage of body fat (certain animals). (Such internal cues are not to be confused with hormones, which directly produce sexual maturity – the production/release of those hormones is triggered by such cues.) Role of reproductive organs Sexual maturity is brought about by a maturing of the reproductive organs and the production of gametes. It may also be accompanied ...

Dominance Hierarchy
In biology, a dominance hierarchy (formerly and colloquially called a pecking order) is a type of social hierarchy that arises when members of animal social animal , social groups interact, creating a ranking system. A dominant higher-ranking individual is sometimes called an alpha, and the submissive lower-ranking individual a beta. Different types of interactions can result in dominance depending on the species, including ritualized displays of aggression or direct physical violence. In social living groups, members are likely to compete for access to limited resources and mating , mating opportunities. Rather than fighting each time they meet, relative rank is established between individuals of the same sex, with higher-ranking individuals often gaining more access to resources and mates. Based on repetitive interactions, a social order is created that is subject to change each time a dominant animal is challenged by a subordinate one. Definitions Dominance is an individu ...

Springbok
The springbok (''Antidorcas marsupialis'') is a medium-sized antelope found mainly in south and southwest Africa. The sole member of the genus ''Antidorcas'', this bovid was first described by the German zoologist Eberhard August Wilhelm von Zimmermann in 1780. Three subspecies are identified. A slender, long-legged antelope, the springbok reaches at the shoulder and weighs between . Both sexes have a pair of black, long horns that curve backwards. The springbok is characterised by a white face, a dark stripe running from the eyes to the mouth, a light-brown coat marked by a reddish-brown stripe that runs from the upper fore leg to the buttocks across the flanks like the Thomson's gazelle, and a white rump flap. Active mainly at dawn and dusk, springbok form harems (mixed-sex herds). In earlier times, springbok of the Kalahari desert and Karoo migrated in large numbers across the countryside, a practice known as ''trekbokking''. A feature, peculiar but not unique, to t ...

Themeda Triandra
} ''Themeda triandra'' is a species of perennial tussock-forming grass widespread in Africa, Australia, Asia and the Pacific. In Australia it is commonly known as kangaroo grass and in East Africa and South Africa it is known as red grass and red oat grass or as ''rooigras'' in Afrikaans. Kangaroo grass was formerly thought to be one of two species, and was named ''Themeda australis''. The plant has traditional uses as food and medicine in Africa and Australia. Indigenous Australians harvested it to make bread and string for fishing nets around 30,000 years ago. It was used as livestock feed in early colonial Australia, but this use was largely replaced by introduced plants. there is a large government-funded project under way to investigate the possibility of growing kangaroo grass commercially in Australia for use as a regular food source for humans. Description ''Themeda triandra'' is a grass which grows in dense tufts up to tall and wide. It flowers in summer, produci ...

Graminivore
A graminivore is a herbivorous animal that feeds primarily on grass, specifically "true" grasses, plants of the family Poaceae (also known as Graminae). Graminivory is a form of grazing. These herbivorous animals have digestive systems that are adapted to digest large amounts of cellulose, which is abundant in fibrous plant matter and more difficult to break down for many other animals. As such, they have specialized enzymes to aid in digestion and in some cases symbiotic bacteria that live in their digestive track and "assist" with the digestive process through fermentation as the matter travels through the intestines. Horses, cattle, geese, guinea pigs, hippopotamuses, capybara and giant pandas are examples of vertebrate graminivores. Some carnivorous vertebrates, such as dogs and cats, are known to eat grass occasionally. Grass consumption in dogs can be a way to rid their intestinal tract of parasites that may be threatening to the carnivore's health. Various invertebrates ...
