Encephalartos Ferox-female-cone-BSI-yercaud-salem-India
''Encephalartos'' is a genus of cycad native to Africa. Several species of ''Encephalartos'' are commonly referred to as bread trees, bread palms or kaffir bread, since a bread-like starchy food can be prepared from the centre of the stem. The genus name is derived from the Greek words ''en'' (within), ''kephalē'' (head), and ''artos'' (bread), referring to the use of the pith to make food. They are, in evolutionary terms, some of the most primitive living gymnosperms. All the species are endangered, some critically, due to their exploitation by collectors and traditional medicine gatherers. The whole genus is listed under CITES Appendix I which prohibits international trade in specimens of these species except for certain non-commercial motives, such as scientific research. Description Several of the species possess stout trunks. In '' E. cycadifolius'', the main trunks are up to high, and several of them may be united at a base where a former main trunk once grew.

Khoikhoi
Khoekhoen (singular Khoekhoe) (or Khoikhoi in the former orthography; formerly also ''Hottentot (racial term), Hottentots''"Hottentot, n. and adj." ''OED Online'', Oxford University Press, March 2018, www.oed.com/view/Entry/88829. Accessed 13 May 2018. Citing G. S. Nienaber, 'The origin of the name “Hottentot” ', ''African Studies'', 22:2 (1963), 65-90, . See also . ) are the traditionally Nomad, nomadic pastoralist Indigenous peoples of Africa, indigenous population of southwestern Africa. They are often grouped with the hunter-gatherer San people, San (literally "Foragers") peoples. The designation "Khoekhoe" is actually a ''kare'' or praise address, not an ethnic endonym, but it has been used in the literature as an ethnic term for Khoe–Kwadi languages, Khoe-speaking peoples of Southern Africa, particularly pastoralist groups, such as the Griqua people, !Ora, !Gona, Nama people, Nama, Khoemana, Xiri and Damara people, ǂNūkhoe nations.

Encephalartos Ngoyanus
''Encephalartos ngoyanus'' is a species of cycad in Ngoye Forest, in KwaZulu-Natal, South Africa. Description The stem is 30 cm high for a diameter of 15–20 cm. The leaves are 50 to 150 cm long, dark green in color, with leaflets that branch off opposite to an angle of 180° from the rachis and that are reduced to thorns towards the base of the leaf. It is a dioecious species, with yellow, ovoid male cones 20–25 cm long by 5–7 cm in diameter, and yellow, ovoid female cones 25 cm long by 12–15 cm in diameter. The seeds are oblong in shape, 25–30 mm long and 15–20 mm wide, with a red sarcotesta The sarcotesta is a fleshy seedcoat, a type of testa. Examples of seeds with a sarcotesta are pomegranate and some cycad seeds. The sarcotesta of pomegranate seeds consists of epidermal cells derived from the integument In biology, an integu ....

Geometer Moth
The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek ''geo'' γεω (derivative form of or "the earth"), and ''metron'' "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. A very large family, it has around 23,000 species of moths described, and over 1400 species from six subfamilies indigenous to North America alone. A well-known member is the peppered moth, ''Biston betularia'', which has been subject of numerous studies in population genetics. Several other geometer moths are notorious pests. Adults Many geometrids have slender abdomens and broad wings which are usually held flat with the hindwings visible. As such, they appear rather butterfly-like, but in most respects they are typical moths; the majority fly at night, they possess a frenulum to link the wings, and the ...

Aposematic
Aposematism is the advertising by an animal to potential predators that it is not worth attacking or eating. This unprofitability may consist of any defences which make the prey difficult to kill and eat, such as toxicity, venom, foul taste or smell, sharp spines, or aggressive nature. These advertising signals may take the form of conspicuous coloration, sounds, odours, or other perceivable characteristics. Aposematic signals are beneficial for both predator and prey, since both avoid potential harm. The term was coined in 1877 by Edward Bagnall Poulton for Alfred Russel Wallace's concept of warning coloration. Aposematism is exploited in Müllerian mimicry, where species with strong defences evolve to resemble one another. By mimicking similarly coloured species, the warning signal to predators is shared, causing them to learn more quickly at less of a cost. A genuine aposematic signal that a species actually possesses chemical or physical defences is not the only way to d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vervet Monkey
The vervet monkey (''Chlorocebus pygerythrus''), or simply vervet, is an Old World monkey of the family Cercopithecidae native to Africa. The term "vervet" is also used to refer to all the members of the genus ''Chlorocebus''. The five distinct subspecies can be found mostly throughout Southern Africa, as well as some of the eastern countries. Vervets were introduced to Florida, St. Kitts and Nevis, Barbados, and Cape Verde. These mostly herbivorous monkeys have black faces and grey body hair color, ranging in body length from about for females, to about for males. In addition to behavioral research on natural populations, vervet monkeys serve as a nonhuman primate model for understanding genetic and social behaviors of humans. They have been noted for having human-like characteristics, such as hypertension, anxiety, and social and dependent alcohol (drug), alcohol use. Vervets live in social groups ranging from 10 to 70 individuals, with males moving to other groups at the tim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
