Carl Peter Thunberg
Carl Peter Thunberg, also known as Karl Peter von Thunberg, Carl Pehr Thunberg, or Carl Per Thunberg (11 November 1743 – 8 August 1828), was a Swedish naturalist and an "apostle" of Carl Linnaeus. After studying under Linnaeus at Uppsala University, he spent seven years travelling in southern Africa and Asia, collecting and describing many plants and animals new to European science, and observing local cultures. He has been called "the father of South African botany", "pioneer of Occidental Medicine in Japan", and the "Japanese Linnaeus". Early life Thunberg was born and grew up in Jönköping, Sweden. At the age of 18, he entered Uppsala University where he was taught by Carl Linnaeus, regarded as the "father of modern taxonomy". Thunberg graduated in 1767 after 6 years of studying. To deepen his knowledge in botany, medicine and natural history, he was encouraged by Linnaeus in 1770 to travel to Paris and Amsterdam. In Amsterdam and Leiden Thunberg met the Dutch botanist ...

Knysna () is a town with 76,150 inhabitants (2019 mid-year estimates) in the Western Cape province of South Africa. and is one of the destinations on the loosely defined Garden Route tourist route. It lies at 34° 2' 6.3168'' S and 23° 2' 47.2884'' E., and is situated 60 kilometres east of the city of George on the N2 highway, and 33 kilometres west of the Plettenberg Bay on the same road.

The first of these were various San Hunter-gatherer peoples who inhabited most of Southern Africa in paleolithic. The San were gradually displaced and absorbed by south migrating Khoekhoe peoples. Houtunqua (Outeniqua) Khoe The indigenous inhabitants of the Knysna area are a southern Khoekhoe people called the Houtunqua or Outeniqua. Their name means "The People Who Bear Honey" ...

Papilio Demodocus
''Papilio demodocus'', the citrus swallowtail or Christmas butterfly, is a swallowtail butterfly which commonly occurs over the entirety of sub-Saharan Africa, including Madagascar, besides the southern Arabian Peninsula. The caterpillars feed on various native plants of especially the family Rutaceae, but have also taken to the leaves of cultivated citrus trees. Life cycle Citrus swallowtails pass through approximately three generations per year. Eggs Female butterflies lay their eggs singly on citrus leaves. After about six days, the egg hatches into an immature larva. Immature larva The immature larvae are black, yellow, and white with spikes. Their coloration provides effective camouflage, as they resemble bird droppings. They grow to a length of 10 or 15 mm before changing into mature larvae. Mature larva Mature larvae are green with white or pink markings and eyespots. They grow to a maximum length of about 45 mm. Mature caterpillars lack the camouflage of ...

Southern African Sand Forest
Southern African Sand Forest is a sand forest, or a subtropical forest plant community of the tropical and subtropical dry broadleaf forests biome. It grows on ancient sand dunes in northern KwaZulu-Natal and southern Mozambique. In South Africa these forests are known simply as Sand Forest, while in Mozambique they are known as Licuati Forest. The Southern African sand forest is part of the Maputaland coastal forest mosaic ecoregion. Origins Sand forests are thought to be relics of coastal dune forests, which have been separated from the ocean for more than a million years as the shoreline has shifted slowly eastwards over the millennia. Dunes have accreted on the southeast African coastal plain since the Pliocene, and frequent sand mobilization events during climatic changes have resulted in some reworking of the dunes. The geological history of the region suggests that the current ecosystems here may be of recent derivation and many endemic plant taxa comply with the concept ...

Flora Of Africa
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
