Anoa (armoured Personnel Carrier)
Anoa, also known as dwarf buffalo and ''sapiutan'', are two species of the genus ''Bubalus'', placed within the subgenus ''Anoa'' and endemic to the island of Sulawesi in Indonesia: the mountain anoa (''Bubalus quarlesi'') and the lowland anoa (''Bubalus depressicornis''). Both live in undisturbed rainforests and are similar in appearance to miniature water buffaloes, weighing . 'Anoa' itself is Celebic in origin cognate to words in other related Philippine languages in the same Austronesian family that name the common water buffalo (''anwáng'' in Tagalog, ''nuáng'' in Ilocano, nuwang in Ifugaw etc.). Both species of anoa have been classified as endangered since the 1960s and the populations continue to decrease. Fewer than 5,000 animals of each species likely remain. Reasons for their decline include poaching for hides, horns, and meat by the local peoples and loss of habitat due to the advancement of settlement. Currently, poaching is the most serious factor in most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surabaya Zoo
Surabaya Zoo (; sometimes abbreviated as ''KBS'' and ), is a zoo located in the city of Surabaya in East Java. History Surabaya Zoo was established by decree of the Governor General of the Netherlands East Indies on 31 August 1916 as ''Soerabaiasche Planten-en Dierentuin'' on the merit of the journalist H. F. K. Kommer who had the hobby of collecting animals. In 1916, the first Surabaya Zoo was established in Kaliondo. On 28 September 1917, the zoo was moved to Groedo Road. In April 1918, Surabaya Zoo sold tickets to enter the zoo. In 1920, the zoo was transferred to another new location in the Darmo area, on a plot of land measuring 30,500 m2 belonging to the ''Oost-Java Stoomtram Maatschappij'' (steam tramway company of East Java). On 21 July 1922, the zoo experienced its first financial crisis and there was a plan to disestablish the zoo, but the decision was not agreed by the Surabaya municipality at that time. On 11 May 1923, it was decided to establish a new association ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Horn (anatomy)
A horn is a permanent pointed projection on the head of various animals that consists of a covering of keratin and other proteins surrounding a core of live bone. Horns are distinct from antlers, which are not permanent. In mammals, true horns are found mainly among the ruminant artiodactyls, in the families Antilocapridae ( pronghorn) and Bovidae ( cattle, goats, antelope etc.). Cattle horns arise from subcutaneous connective tissue (under the scalp) and later fuse to the underlying frontal bone. One pair of horns is usual; however, two or more pairs occur in a few wild species and in some domesticated breeds of sheep. Polycerate (multi-horned) sheep breeds include the Hebridean, Icelandic, Jacob, Manx Loaghtan, and the Navajo-Churro. Horns usually have a curved or spiral shape, often with ridges or fluting. In many species, only males have horns. Horns start to grow soon after birth and continue to grow throughout the life of the animal (except in pronghorns, whi ...

Tropical Rainforest
Tropical rainforests are dense and warm rainforests with high rainfall typically found between 10° north and south of the Equator. They are a subset of the tropical forest biome that occurs roughly within the 28° latitudes (in the torrid zone between the Tropic of Cancer and Tropic of Capricorn). Tropical rainforests are a type of tropical moist broadleaf forest, that includes the more extensive seasonal tropical forests. True rainforests usually occur in tropical rainforest climates where no dry season occurs; all months have an average precipitation of at least . Seasonal tropical forests with tropical monsoon climate, tropical monsoon or tropical savanna climate, savanna climates are sometimes included in the broader definition. Tropical rainforests ecosystems are distinguished by their consistent, high temperatures, exceeding monthly, and substantial annual rainfall. The abundant rainfall results in nutrient-poor, leached soils, which profoundly affect the flora and fau ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowland
Upland and lowland are conditional descriptions of a plain based on elevation above sea level. In studies of the ecology of freshwater rivers, habitats are classified as upland or lowland. Definitions Upland and lowland are portions of a plain that are conditionally categorized by their elevation above the sea level. Lowlands are usually no higher than , while uplands are somewhere around to . On unusual occasions, certain lowlands such as the Caspian Depression lie below sea level. Uplands areas tend to spike into valleys and mountains, forming mountain ranges while lowland areas tend to be uniformly flat, although both can vary such as the Mongolian Plateau. Upland habitats are cold, clear and rocky whose rivers are fast-flowing in mountainous areas; lowland habitats are warm with slow-flowing rivers found in relatively flat lowland areas, with water that is frequently colored by sediment and organic matter. These classifications overlap with the geological definitions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bovid
The Bovidae comprise the family (biology), biological family of cloven-hoofed, ruminant mammals that includes Bos, cattle, bison, Bubalina, buffalo, antelopes (including Caprinae, goat-antelopes), Ovis, sheep and Capra (genus), goats. A member of this family is called a bovid. With 143 Extant taxon, extant species and 300 known Extinction, extinct species, the family Bovidae consists of 11 (or two) major subfamilies and thirteen major tribes. The family evolved 20 million years ago, in the early Miocene. The bovids show great variation in size and Fur, pelage colouration. Except some Polled livestock, domesticated forms, all male bovids have two or more horn (anatomy), horns, and in many species, females possess horns, too. The size and shape of the horns vary greatly, but the basic structure is always one or more pairs of simple bony protrusions without branches, often having a spiral, twisted or fluted form, each covered in a permanent sheath of keratin. Most bovids bear 30 to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lowland Anoa
The lowland anoa ''(Bubalus depressicornis)'' is a species of buffalo endemic to Sulawesi. Its closest relative is the mountain anoa, and it is still a debate as to whether the two are the same species or not. It is also related to the water buffalo, and both are classified in the genus ''Bubalus''. Taxonomy Skulls of anoa cannot be accurately identified as to species, and there is likely hybridizing and interbreeding between the mountain anoa and lowland anoa in the zoo population. It is questioned as to whether the two species were actually different due to them occurring together in many different areas, as well as some interbreeding. A study of the mtDNA of ten specimens from different localities found a high mitochondrial genetic diversity between individuals identified as one or the other species, indicating support for recognition as two species. The extinct '' Bubalus grovesi'' of southern Sulawesi appears to be a close relative of both anoa species. Description The lo ...

Mitochondrial
A mitochondrion () is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. The term ''mitochondrion'', meaning a thread-like granule, was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the "powerhouse of the cell", a phrase popularized by Philip Siekevitz in a 1957 ''Scientific American'' article of the same name. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). The multicellular animal '' Henneguya salminicola'' is known to have retained mitochondrion-related organelles despite a complete loss of their mitochondrial genome. A large number of unicellular organisms, such as microsporidia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MtDNA
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits tra ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Buton
Buton (also Butung, Boeton or Button) is an island in Indonesia located off the southeast peninsula of Sulawesi. It covers roughly 4,727 square kilometers in area, or about the size of Madura; it is the 129th List of islands by area, largest island in the world and Indonesia's 19th largest in area. History In the precolonial era, the island, then usually known as Butung, was within the sphere of influence of Sultanate of Ternate, Ternate. Especially in the sixteenth century, Buton served as an important secondary regional center within the Ternaten empire, controlling regional trade and collecting tribute to be sent to Ternate. The Sultanate of Buton ruled over the island from the 14th until the 20th century. Sultan Murhum, the first Islamic monarch on the island, is remembered in the name of the island's major harbor, Murhum Harbor, in Baubau. Geography Its largest town is Baubau, where the Wolio language, Wolio and Cia-Cia language, Cia-Cia languages are spoken. Major near ...

Siwalik Hills
The Sivalik Hills, also known as Churia Hills, are a mountain range of the outer Himalayas. The literal translation of "Sivalik" is 'tresses of Shiva'. The hills are known for their numerous fossils, and are also home to the Soanian Middle Paleolithic archaeological culture. Geography The Sivalik Hills are a mountain range of the outer Himalayas that stretches over about from the Indus River eastwards close to the Brahmaputra River, spanning the northern parts of the Indian subcontinent. It is wide with an average elevation of . Between the Teesta and Raidāk Rivers in Assam is a gap of about . They are well known for their Neogene and Pleistocene aged vertebrate fossils. Geology Geologically, the Sivalik Hills belong to the Tertiary deposits of the outer Himalayas. They are chiefly composed of sandstone and conglomerate rock formations, which are the solidified detritus of the Himalayas to their north; they are poorly consolidated.

Race (biology)
In Taxonomy (biology), biological taxonomy, race is an informal group (taxonomy), informal Taxonomic rank, rank in the taxonomic hierarchy for which various definitions exist. Sometimes it is used to denote a level below that of subspecies, while at other times it is used as a synonym for subspecies. It has been used as a higher rank than Strain (biology), strain, with several strains making up one race. Races may be Genetics, genetically distinct populations of individuals within the same species, Republished without known revision several times since 1999, and originally published as: or they may be defined in other ways, e.g. geographically, or physiologically. Genetic isolate, Genetic isolation between races is not complete, but genetic differences may have accumulated that are not (yet) sufficient to separate species. The term is recognized by some, but not governed by any of Nomenclature code, the formal codes of biological nomenclature. Taxonomic units below the level o ...
