Nephila Komaci
''Nephila komaci'' is a species of golden orb-web spider. It is the largest web-spinning spider known. A few specimens have been found in South Africa and Madagascar. Discovery This species was first identified in a Pretoria museum collection in 2000. The species is named in honor of Andrej Komac, a late friend of one of the arachnologists who reported its discovery in 2009. It was not discovered in the wild until 2007, when it was located in Tembe Elephant Park in South Africa. It was one of the first new ''Nephila'' spiders to be discovered in more than a century; most were discovered in the 19th century. Description ''N. komaci'' females are the largest ''Nephila'' yet discovered. Displaying sexual size dimorphism commonly observed in various species of spiders, the size of a male reaches a leg span of only about 2.5 centimetres, with a body length of about 9 mm, roughly one fifth of that of a female. The tip-to-tip leg span of a female is about 12 cm (body length ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Insemination
Insemination is the introduction of sperm into a female’s reproductive system for the purpose of impregnating, also called fertilizing, the female for sexual reproduction. The sperm is introduced into the uterus of a mammal or the oviduct of an oviparous (egg-laying) animal. In mammals, insemination normally occurs during sexual intercourse or copulation, but insemination can take place in other ways, such as by artificial insemination. In humans, the act and form of insemination has legal, moral and interpersonal implications. However, whether insemination takes place naturally or by artificial means, the pregnancy and the progress of it will be the same. Insemination may be called ''in vivo'' fertilisation (from ''in vivo'' meaning "within the living") because an egg is fertilized inside the body, this is in contrast with in vitro fertilisation (IVF). In plants, the fertilization process is referred to as pollination. It is the process of transfer of pollen grains from one ...

Araneidae
Orb-weaver spiders are members of the spider family Araneidae. They are the most common group of builders of spiral wheel-shaped webs often found in gardens, fields, and forests. The English word "orb" can mean "circular", hence the English name of the group. Araneids have eight similar eyes, hairy or spiny legs, and no stridulating organs. The family has a cosmopolitan distribution, including many well-known large or brightly colored garden spiders. With 3,108 species in 186 genera worldwide, the Araneidae comprise the third-largest family of spiders (behind the Salticidae and Linyphiidae). Araneid webs are constructed in a stereotypical fashion, where a framework of nonsticky silk is built up before the spider adds a final spiral of silk covered in sticky droplets. Orb webs are also produced by members of other spider families. The long-jawed orb weavers (Tetragnathidae) were formerly included in the Araneidae; they are closely related, being part of the superfamily Araneo ...

Albany, South Africa
Albany, South Africa (also known as Cape Borders, Cape Frontier, Settler Country, and Western Region) was a district in the Eastern Cape, South Africa. Grahamstown was traditionally the administrative capital, cultural centre and largest town of the Albany district. The area was previously known as the 'Zuurveld' by migrating Boer farmers in the late 18th century, and it lay near the boundary between the Cape Colony and the traditional Xhosa lands to the east. The 1820 Settlers were instrumental in settling and farming the district and giving it some of its distinctive local culture. The ANC government merged the Albany area with the large Xhosa township of Alice as the municipal area of 'Cacadu'br> History General Jacob Glen Cuyler, the ''Landdrost'' of the Uitenhage district, named the area between the Sundays and Fish rivers "Albany" after Albany in his native New York. Albany became the destination for the 1820 Settlers by the Cape Colony's new British masters. It accept ...

Pondoland
Pondoland or Mpondoland (Xhosa: ''EmaMpondweni''), is a natural region on the South African shores of the Indian Ocean. It is located in the coastal belt of the Eastern Cape province. Its territory is the former Mpondo Kingdom of the Mpondo people. Geography Mpondoland stretches between the Mthatha River, whose mouth is its southernmost point, and the Mtamvuna River in the north along a coastal strip that is not more than 50 km wide. The Mzimvubu River divides Mpondoland into an eastern and a western region. It is a mountainous area whose main vegetation consists in thornveld, grassland, as well as subtropical evergreen forests in the humid coastal valleys. History The Khoikhoi and San people had inhabited the region since ancient times in scattered nomadic groups. About 500 AD the Xhosa speaking Ngunis settled in the area, for the mountain grasslands were a good resource for cattle-rearing. Geographically Mpondoland was a remote area, not strongly affected by the events ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Biodiversity Hotspot
A biodiversity hotspot is a biogeographic region with significant levels of biodiversity that is threatened by human habitation. Norman Myers wrote about the concept in two articles in ''The Environmentalist'' in 1988 and 1990, after which the concept was revised following thorough analysis by Myers and others into “Hotspots: Earth’s Biologically Richest and Most Endangered Terrestrial Ecoregions” and a paper published in the journal ''Nature'', both in 2000. To qualify as a biodiversity hotspot on Myers' 2000 edition of the hotspot map, a region must meet two strict criteria: it must contain at least 1,500 species of vascular plants (more than 0.5% of the world's total) as endemics, and it has to have lost at least 70% of its primary vegetation. Globally, 36 zones qualify under this definition. These sites support nearly 60% of the world's plant, bird, mammal, reptile, and amphibian species, with a high share of those species as endemics. Some of these hotspots support up ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mating
In biology, mating is the pairing of either opposite-sex or hermaphroditic organisms for the purposes of sexual reproduction. ''Fertilization'' is the fusion of two gametes. ''Copulation'' is the union of the sex organs of two sexually reproducing animals for insemination and subsequent internal fertilization. Mating may also lead to external fertilization, as seen in amphibians, fishes and plants. For most species, mating is between two individuals of opposite sexes. However, for some hermaphroditic species, copulation is not required because the parent organism is capable of self-fertilization (autogamy); for example, banana slugs. The term ''mating'' is also applied to related processes in bacteria, archaea and viruses. Mating in these cases involves the pairing of individuals, accompanied by the pairing of their homologous chromosomes and then exchange of genomic information leading to formation of recombinant progeny (see mating systems).

Sex Organ
A sex organ (or reproductive organ) is any part of an animal or plant that is involved in sexual reproduction. The reproductive organs together constitute the reproductive system. In animals, the testis in the male, and the ovary in the female, are called the ''primary sex organs''. All others are called ''secondary sex organs'', divided between the external sex organs—the genitals or external genitalia, visible at birth in both sexes—and the internal sex organs. Mosses, ferns, and some similar plants have gametangia for reproductive organs, which are part of the gametophyte. The flowers of flowering plants produce pollen and egg cells, but the sex organs themselves are inside the gametophytes within the pollen and the ovule. Coniferous plants likewise produce their sexually reproductive structures within the gametophytes contained within the cones and pollen. The cones and pollen are not themselves sexual organs. Terminology The ''primary sex organs'' are the gonads, a p ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Ecdysis
Ecdysis is the moulting of the cuticle in many invertebrates of the clade Ecdysozoa. Since the cuticle of these animals typically forms a largely inelastic exoskeleton, it is shed during growth and a new, larger covering is formed. The remnants of the old, empty exoskeleton are called exuviae. After moulting, an arthropod is described as ''teneral'', a ''callow''; it is "fresh", pale and soft-bodied. Within one or two hours, the cuticle hardens and darkens following a tanning process analogous to the production of leather. During this short phase the animal expands, since growth is otherwise constrained by the rigidity of the exoskeleton. Growth of the limbs and other parts normally covered by the hard exoskeleton is achieved by transfer of body fluids from soft parts before the new skin hardens. A spider with a small abdomen may be undernourished but more probably has recently undergone ecdysis. Some arthropods, especially large insects with tracheal respiration, expand thei ...
