Bonobo Sexual Behavior 1
The bonobo (; ''Pan paniscus''), also historically called the pygmy chimpanzee (less often the dwarf chimpanzee or gracile chimpanzee), is an endangered great ape and one of the two species making up the genus '' Pan'' (the other being the common chimpanzee, ''Pan troglodytes''). While bonobos are today recognized as a distinct species in their own right, they were initially thought to be a subspecies of ''Pan troglodytes'', because of the physical similarities between the two species. Taxonomically, members of the chimpanzee/bonobo subtribe Panina—composed entirely by the genus '' Pan''—are collectively termed ''panins''. Bonobos are distinguished from common chimpanzees by relatively long limbs, pinker lips, a darker face, a tail-tuft through adulthood, and parted, longer hair on their heads. Some individuals have sparser, thin hair over parts of their bodies. The bonobo is found in a area within the Congo Basin of the Democratic Republic of the Congo (DRC), Central Afric ...

Pleistocene
The Pleistocene ( ; referred to colloquially as the ''ice age, Ice Age'') is the geological epoch (geology), epoch that lasted from 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 () 'most' and (; Latinized as ) 'new'. The aridification and cooling trends of the preceding Neogene were continued in the Pleistocene. The climate was strongly variable depending on the glacial cycle, oscillating between cold Glacial period, glacial periods and warmer Interglacial, int ...

Royal Antelope
The royal antelope (''Neotragus pygmaeus'') is a West African antelope recognized as the world's smallest. It was first described by Swedish zoologist Carl Linnaeus in 1758. It stands up to merely at the shoulder and weighs . A characteristic feature is the long and slender legs, with the hindlegs twice as long as the forelegs. Horns are possessed only by males; the short, smooth, spiky horns measure and bend backward. The soft coat is reddish to golden brown, in sharp contrast with the white ventral parts. In comparison to Bates's pygmy antelope, the royal antelope has a longer muzzle, broader lips, a smaller mouth and smaller cheek muscles. Typically nocturnal (active at night), the royal antelope exhibits remarkable alertness. Territories are marked with dung. An herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Like other neotragines, the royal antelope is monogamous. Both sexes can become s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bolobo
Bolobo is a town on the Congo River in Mai-Ndombe Province in the western part of the Democratic Republic of the Congo (DRC). It is the administrative center of Bolobo Territory. As of 2009 it had an estimated population of 31,366. People The predominant ethnic group is that of the Banunu people, who originate from upriver and whose Bobangi language was the former trade language for the area. Lingala, one of the four national languages of the DRC, is now used as the lingua franca. Other local ethnicities include the Bateke (the natives of this area) and Batende, who have their own Bantu languages. Early European visitors Bolobo was visited by Henry Morton Stanley on his trip down the Congo River in the 19th century.Stanley, H.M., 1899, Through the Dark Continent, London: G.

Heinz Heck
Heinz Heck (22 January 1894 – 5 March 1982) was a German biologist and director of Hellabrunn Zoo (''Tierpark Hellabrunn'') in Munich. He was born in Berlin and died in Munich. With his brother, Lutz Heck, who was director of the Berlin Zoological Garden, he worked on two breeding back projects to recreate extinct species. The Heck horse aimed to recreate the tarpan, and the Heck cattle, aimed to recreate the aurochs, the wild cattle of the European forest. This work has been criticised on grounds that once an animal is extinct, it cannot re-exist. This was contrary to Heck's view, which is that while genes of an extinct animal still exist in extant taxon, extant descendants, the animal could still be recreated. Under Nazi Germany, Heinz Heck was among the first political prisoners to be interned—and later released—in Dachau concentration camp, Dachau for suspected membership in the Communist Party and for his brief marriage to a Jewish woman. Heck also played an im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eduard Paul Tratz
Eduard Paul Tratz (25 September 1888, in Salzburg – 5 January 1977, in Salzburg) was an Austrian zoologist. Ahnenerbe Tratz was the founder of Salzburg's ''Haus der Natur'', one of the leading museums of natural history in Austria, in 1924. A member of the Nazi Party, he ensured significant funding for the museum after the Anschluss and spent much of it adding eight new areas dealing with such topics as eugenics and racial hygiene. He played a leading role in helping to popularise " Rassenkunde" in Austria and was also a departmental head in the Ahnenerbe (and thus entitled to officer rank in the Schutzstaffel).Pringle, ''The Master Plan'', p. 311 In late 1939, Tratz was one of a number of leading scholars chosen by Wolfram Sievers to be sent to Poland in order to help plunder the country's museums. His main port of call was the State Zoological Museum in Warsaw, where his haul included 147 rare birds, three wisents, two wildcats, a Nile crocodile, numerous skeletons and ...

Habitat Destruction
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduction of invasive species, ecosystem nutrient depletion, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as the ...

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 an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations. The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity. Major species assessors include BirdLife International, the Institute of Zoology (the research division of the Zoological Society of London), the World Conservation Monitoring Centre, and many Specialist Groups w ...

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, invasive species, and climate change. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speciation
Speciation is the evolutionary process by which populations evolve to become distinct species. The biologist Orator F. Cook coined the term in 1906 for cladogenesis, the splitting of lineages, as opposed to anagenesis, phyletic evolution within lineages. Charles Darwin was the first to describe the role of natural selection in speciation in his 1859 book ''On the Origin of Species''. He also identified sexual selection as a likely mechanism, but found it problematic. There are four geographic modes of speciation in nature, based on the extent to which speciating populations are isolated from one another: allopatric speciation, allopatric, peripatric speciation, peripatric, parapatric speciation, parapatric, and sympatric speciation, sympatric. Whether genetic drift is a minor or major contributor to speciation is the subject of much ongoing discussion. Rapid sympatric speciation can take place through polyploidy, such as by doubling of chromosome number; the result is progeny wh ...
