Charaxes Ansorgei
__NOTOC__ ''Charaxes ansorgei'' is a butterfly in the family Nymphalidae. It is found in Sudan, the Democratic Republic of Congo, Uganda, Rwanda, Burundi, Kenya, Tanzania, Malawi and Zambia. The habitat consists of montane forest on altitudes between 2,000 and 3,000 meters. The larvae feed on '' Bersama abyssinica abyssinica'', '' Bersama abyssinica englerana'' and '' Bersama paullinoides''.It was once considered to be a very rare species but it is relatively common in dense and inaccessible montane forests Description Nearly allied to the preceding species ''Charaxes brutus'', but has the basal part of the forewing above chestnut-brown, not black; the discal band of the hindwing is bluish white. Male- discal band of the fore wing ochre-yellow, continuous to vein 4, then broken up into spots, one each in cellules 4 and 7 and two each in 5 and 6; on the proximal side of the discal band the ground-colour forms black spots in cellules 2—6; small light marginal dots; hindwing w ...

Lionel Walter Rothschild, 2nd Baron Rothschild, Baron de Rothschild, (8 February 1868 – 27 August 1937) was a British banker, politician, zoologist and soldier, who was a member of the Rothschild family. As a Zionist leader, he was presented with the Balfour Declaration, which pledged British support for a Jewish national home in Palestine. Rothschild was the president of the Board of Deputies of British Jews from 1925 to 1926. Early life Walter Rothschild was born in London as the eldest son and heir of Emma Louise von Rothschild and Nathan Rothschild, 1st Baron Rothschild, an immensely wealthy financier of the international Rothschild financial dynasty and the first Jewish peer in England. The eldest of three children, Walter was deemed to have delicate health and was educated at home. As a young man, he travelled in Europe, attending the University of Bonn for a year before entering Magdalene College, Cambridge. In 1889, leaving Cambridge after two years, he was ...

Albertine Rift
The Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania. It extends from the northern end of Lake Albert to the southern end of Lake Tanganyika. The geographical term includes the valley and the surrounding mountains. Geology The Albertine Rift and the mountains are the result of tectonic movements that are gradually splitting the Somali Plate away from the rest of the African continent. The mountains surrounding the rift are composed of uplifted Pre-Cambrian basement rocks, overlaid in parts by recent volcanic rocks. Lakes and rivers The northern part of the rift is crossed by two large mountain ranges, the Rwenzori Mountains between Lake Albert and Lake Rutanzige (formerly Lake Edward) and the Virunga Mountains between Lake Rutanzige and Lake Kivu. The Virungas form a barrier between the Nile Basin to the north and east and the Congo Basin to the west and south. Lak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberdare Range
The Aberdare Range (formerly the Sattima Range, Kikuyu: ''Nyandarua'') is a 160 km (100 mile) long mountain range of upland, north of Kenya's capital Nairobi with an average elevation of . It straddles across the counties of Nyandarua, Nyeri, Muranga, Kiambu and Laikipia. The mountain range is located in west central Kenya, northeast of Naivasha and Gilgil and lies just south of the Equator. The mountain range is called Nyandarua among the Agikuyu people in whose territory this forest and mountain range is located. The name Nyandarua comes from the Kikuyu word rwandarua meaning a drying hide, due to the distinctive fold of its silhouette. Topology The Aberdare Range forms a section of the eastern rim of the Great Rift Valley running roughly north to south. On the west, the range falls off steeply into the Kinangop Plateau and then into the Great Rift Valley. On the east, the range slopes more gently. Lake Naivasha and the distant Mau Escarpment can be seen from peaks in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charaxes Dowsetti
''Charaxes dowsetti'' is a butterfly in the family Nymphalidae. It is found on the Nyika Plateau in Malawi. The habitat consists of montane forests at altitudes above 2,200 meters. The larvae feed on ''Agarista salicifolia''. Related species Historical attempts to assemble a cluster of presumably related species into a "''Charaxes jasius'' Group" have not been wholly convincing. More recent taxonomic revision, corroborated by phylogenetic research, allow a more rational grouping congruent with cladistic relationships. Within a well-populated clade of 27 related species sharing a common ancestor approximately 16 mya during the Miocene, 26 are now considered together as The ''jasius'' Group. One of the two lineages within this clade forms a robust monophyletic group of seven species sharing a common ancestor approximately 2-3 mya, i.e. during the Pliocene, [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...

Charaxes Jasius
''Charaxes jasius'', the two-tailed pasha, is a butterfly in the family Nymphalidae. It is the only European species of the genus ''Charaxes''. Divergence of the Mediterranean species ''C. jasius'' from the last common ancestor it shared with its closest related species still flying in the Afrotropical realm most probably occurred around 2 mya, i.e. during the Pliocene. *''Charaxes legeri'' *''Charaxes saturnus'' tat.rev.2005ref name="Turlin 2005"/> *'' Charaxes pelias'' *''Charaxes castor'' *''Charaxes hansali'' Clade 2: contains the three well-populated additional subgroups (19 species) of the jasius Group: *the ''brutus'' subgroup (4 species): *''Charaxes brutus'' *''Charaxes antiquus'' *''Charaxes junius'' *''Charaxes andara'' *the ''pollux'' subgroup (4 species): *'' Charaxes pollux'' *'' Charaxes phoebus'' *'' Charaxes ansorgei'' *'' Charaxes dowsetti'' *the ''eudoxus'' subgroup (11 species): *'' Charaxes eudoxus'' *'' Charaxes lucyae'' *'' Charaxes richelmanni'' *'' Char ...

Miocene
The Miocene ( ) is the first geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene is preceded by the Oligocene and is followed by the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by a single distinct global event but consist rather of regionally defined boundaries between the warmer Oligocene and the cooler Pliocene Epoch. During the Early Miocene, the Arabian Peninsula collided with Eurasia, severing the connection between the Mediterranean and Indian Ocean, and allowing a faunal interchange to occur between Eurasia and Africa, including the dispersal of proboscideans into Eurasia.
