Sanetti Plateau
The Sanetti Plateau is a major plateau of the Ethiopian Highlands, in the Oromia Region of Ethiopia. The plateau is the highest part of the Bale Mountains, and is located within Bale Mountains National Park.L.J.G. van der Maesen, X.M. van der Burgt and J.M. van Medenbach de Rooy. 1994. ''The Biodiversity of African Plants: Proceedings, XIVth AETFAT Congress'', 22–27 August 1994, Wageningen, The Netherlands, Published by Springer, Geography The plateau exceeds 4000 meters in elevation, and its highest point is Mount Tullu Dimtu at . The southern edge of the plateau forms a steep escarpment, known as the Harenna escarpment, which descends from 3800 to 2800 meters elevation. The northern slopes drain into the Shebelle River, and the southern slopes are drained by tributaries of the Ganale River, including the Weyib. The southern slopes receive higher rainfall, generally 1000 mm or more annually, while the northern slopes are in the drier rain shadow of the mountains. Flora an ...

Bale Mountains
The Bale Mountains (also known as the Urgoma Mountains) are mountain ranges in the Oromia Region of southeast Ethiopia, south of the Awash River, part of the Ethiopian Highlands. They include Tullu Demtu, the second-highest mountain in Ethiopia (4377 meters), and Mount Batu (4307 meters). The Weyib River, a tributary of the Jubba River, rises in these mountains east of Goba. The Bale Mountains National Park covers 2,200 square kilometers of these mountains. The main attractions of the park are the wild alpine scenery, and the relative ease with which visitors can see unique birds and mammals. Fauna The Bale Mountains are home to many of Ethiopia's endemic animals, notably the Ethiopian wolf (''Canis simensis''), found on the Sanetti Plateau. The park also contains the Harenna Forest, situated to the south of the mountains, which is a largely unexplored area thought to contain many undiscovered species of reptile as well as lions, leopards and various types of antelope.

Eduard Rüppell
Wilhelm Peter Eduard Simon Rüppell (20 November 1794 – 10 December 1884) was a German Natural history, naturalist and List of explorers, explorer. Rüppell is occasionally transliterated to "Rueppell" for the English alphabet, due to german orthography. Biography Rüppell was born in Frankfurt am Main, the son of a prosperous banker, who was a partner in 'Rüppell und Harnier’s Bank'. He was originally destined to be a merchant, but after a visit to Sinai Peninsula, Sinai in 1817, where he met Henry Salt (Egyptologist), Henry Salt and the Swiss-German traveller Johann Ludwig Burckhardt, Ludwig Burckhardt. He explored Giza and the Pyramids with Salt. In 1818, he developed an interest in natural history, and became elected member of the ''Senckenbergische Naturforschende Gesellschaf''. He attended lectures at the University of Pavia and University of Genoa in botany and zoology. Rüppell set off on his first expedition in 1821, accompanied by surgeon Michael Hey as his assistan ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finch
The true finches are small to medium-sized passerine birds in the family Fringillidae. Finches have stout conical bills adapted for eating seeds and nuts and often have colourful plumage. They occupy a great range of habitats where they are usually resident and do not migrate. They have a worldwide distribution except for Australia and the polar regions. The family Fringillidae contains more than two hundred species divided into fifty genera. It includes species known as siskins, canaries, redpolls, serins, grosbeaks and euphonias. Many birds in other families are also commonly called "finches". These groups include the estrildid finches (Estrildidae) of the Old World tropics and Australia; some members of the Old World bunting family (Emberizidae) and the New World sparrow family (Passerellidae); and the Darwin's finches of the Galapagos islands, now considered members of the tanager family (Thraupidae).Newton (1973), Clement ''et al.''

Ethiopian Highlands
The Ethiopian Highlands is a rugged mass of mountains in Ethiopia in Northeast Africa. It forms the largest continuous area of its elevation in the continent, with little of its surface falling below , while the summits reach heights of up to . It is sometimes called the Roof of Africa due to its height and large area. Most of the Ethiopian Highlands are part of central and northern Ethiopia, and its northernmost portion reaches into Eritrea. History In the southern parts of the Ethiopian Highlands once was located the Kingdom of Kaffa, a medieval early modern state, whence the coffee plant was exported to the Arabian Peninsula. The land of the former kingdom is mountainous with stretches of forest. The land is very fertile, capable of three harvests a year. The term ''coffee'' derives from the ar, قهوة, italic=no ()''Oxford English Dictionary'', 1st ed. "coffee, ''n.''" Oxford University Press (Oxford), 1891. and is traced to Kaffa.

Habitat
In ecology, the term habitat summarises the array of resources, physical and biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subtropical
The subtropical zones or subtropics are geographical zone, geographical and Köppen climate classification, climate zones to the Northern Hemisphere, north and Southern Hemisphere, south of the tropics. Geographically part of the Geographical zone#Temperate zones, temperate zones of both hemispheres, they cover the middle latitudes from to approximately 35° north and south. The horse latitudes lie within this range. Subtropical climates are often characterized by hot summers and mild winters with infrequent frost. Most subtropical climates fall into two basic types: humid subtropical climate, humid subtropical (Köppen climate classification, Koppen climate Cfa), where rainfall is often concentrated in the warmest months, for example list of regions of China, Southeast China and the Southeastern United States, and Mediterranean climate, dry summer or Mediterranean climate (Köppen climate classification, Koppen climate Csa/Csb), where seasonal rainfall is concentrated in the c ...

Afromontane
The Afromontane regions are subregions of the Afrotropical realm, one of the Earth's eight biogeographic realms, covering the plant and animal species found in the mountains of Africa and the southern Arabian Peninsula. The Afromontane regions of Africa are discontinuous, separated from each other by lower-lying areas, and are sometimes referred to as the Afromontane archipelago, as their distribution is analogous to a series of sky islands. Geography Afromontane communities occur above elevation near the equator, and as low as elevation in the Knysna-Amatole montane forests of South Africa. Afromontane forests are generally cooler and more humid than the surrounding lowlands. The Afromontane archipelago mostly follows the East African Rift from the Red Sea to Zimbabwe, with the largest areas in the Ethiopian Highlands, the Albertine Rift Mountains of Uganda, Rwanda, Burundi, Democratic Republic of the Congo, and Tanzania, and the Eastern Arc highlands of Kenya and Tanzan ...

Grassland
A grassland is an area where the vegetation is dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes, like clover, and other herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures." (Pilot Assessment of Global Ecosystems, 2000) * "A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
