Great Snakehead
''Channa marulius'' (bullseye snakehead or great snakehead) is a large species of snakehead native to South Asia. Populations in Southeast Asia are now regarded as separate species.Adamson, E. A. S. and R. Britz (2018). The snakehead fish Channa aurolineata is a valid species (Teleostei: Channidae) distinct from Channa marulius. Zootaxa 4514 (4): 542-552.Adamson, E.A.S., R. Britz and S. Lieng (2019). Channa auroflammea, a new species of snakehead fish of the Marulius group from the Mekong River in Laos and Cambodia (Teleostei: Channidae). Zootaxa 4571(3): 398-408. Taxonomy ''C. marulius''—as traditionally defined—is a species complex. A study published in 2017 showed that '' C. pseudomarulius'', formerly regarded as a synonym of ''C. marulius'', is a valid species from the southern Western Ghats. A genetic study published the same year showed that ''C. marulius'' consisted of three clearly separated lineages (not counting the already separated ''C. pseudomarulius''). O ...

Francis Buchanan-Hamilton
Francis Buchanan (15 February 1762 – 15 June 1829), later known as Francis Hamilton but often referred to as Francis Buchanan-Hamilton, was a Scottish physician who made significant contributions as a geographer, zoologist, and botanist while living in India. He did not assume the name of Hamilton until three years after his retirement from India. The standard botanical author abbreviation Buch.-Ham. is applied to plants and animals he described, though today the form "Hamilton, 1822" is more usually seen in ichthyology and is preferred by Fishbase. Early life Francis Buchanan was born at Bardowie, Callander, Perthshire where Elizabeth, his mother, lived on the estate of Branziet; his father Thomas, a physician, came in Spittal and claimed the chiefdom of the name of Buchanan and owned the Leny estate. Francis Buchanan matriculated in 1774 and received an MA in 1779. As he had three older brothers, he had to earn a living from a profession, so Buchanan studied medicine ...

Lineage (evolution)
An evolutionary lineage is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant.The Oxford English Dictionary defines biological lineage as "a sequence of species each of which is considered to have evolved from its predecessorOED definition of lineage/ref> Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics.

Channa
''Channa'' is a genus of predatory fish in the family Channidae, commonly known as snakeheads, native to freshwater habitats in Asia. This genus contains about 50 scientifically described species. The genus has a wide natural distribution extending from Iraq in the west, to Indonesia and China in the east, and parts of Siberia in the Far East. A particularly high richness of species exists in Myanmar (Burma) and northeastern India, and many ''Channa'' species live nowhere else. In contrast, a few widespread species have been introduced to several regions outside their natural range, where they often become invasive. The large and medium-sized ''Channa'' species are among the most common staple food fish in several Asian countries, and they are extensively cultured.Kumar, K., R. Kumar, S. Saurabh, M. Sahoo, A.K.

Assamese Language
Assamese (), also Asamiya ( ), is an Indo-Aryan language spoken mainly in the north-east Indian state of Assam, where it is an official language, and it serves as a ''lingua franca'' of the wider region. The easternmost Indo-Iranian language, it has over 23 million speakers. Nefamese, an Assamese-based pidgin, is used in Arunachal Pradesh, and Nagamese, an Assamese-based Creole language, is widely used in Nagaland. The Kamtapuri language of Rangpur division of Bangladesh and the Cooch Behar and Jalpaiguri districts of India are linguistically closer to Assamese, though the speakers identify with the Bengali culture and the literary language. In the past, it was the court language of the Ahom kingdom from the 17th century. Along with other Eastern Indo-Aryan languages, Assamese evolved at least before the 7th century CE from the middle Indo-Aryan Magadhi Prakrit. Its sister languages include Angika, Bengali, Bishnupriya Manipuri, Chakma, Chittagonian, Hajong, Rajbangsi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mekong
The Mekong or Mekong River is a trans-boundary river in East Asia and Southeast Asia. It is the world's List of rivers by length, twelfth longest river and List of longest rivers of Asia, the third longest in Asia. Its estimated length is , and it drains an area of , discharging of water annually. From the Tibetan Plateau the river runs through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam. The extreme seasonal variations in flow and the presence of rapids and waterfalls in the Mekong make navigation difficult. Even so, the river is a major trade route between western China and Southeast Asia. Names The Mekong was originally called ''Mae Nam Khong'' from a contracted form of Tai language, Tai shortened to ''Mae Khong''. In Thai and Lao, ''Mae Nam'' ("Mother of Water[s]") is used for large rivers and ''Khong'' is the proper name referred to as "River Khong". However, ''Khong'' is an archaic word meaning "river", loaned from Austroasiatic languages, such as Vietnamese ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Geology Of Myanmar
The geology of Myanmar is shaped by dramatic, ongoing tectonic processes controlled by shifting tectonic components as the Indian plate slides northwards and towards Southeast Asia. Myanmar spans across parts of three tectonic plates (the Indian Plate, Burma microplate and Shan Thai Block) separated by north-trending faults. To the west, a highly oblique subduction zone separates the offshore Indian plate from the Burma microplate, which underlies most of the country. In the center-east of Myanmar, a right lateral strike slip fault extends from south to north across more than . These tectonic zones are responsible for large earthquakes in the region. The India-Eurasia plate collision which initiated in the Eocene provides the last geological pieces of Myanmar, and thus Myanmar preserves a more extensive Cenozoic geological record as compared to records of the Mesozoic and Paleozoic eras. Myanmar is physiographically divided into three regions: the Indo-Burman Range, Myanmar Cent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thailand
Thailand ( ), historically known as Siam () and officially the Kingdom of Thailand, is a country in Southeast Asia, located at the centre of the Indochinese Peninsula, spanning , with a population of almost 70 million. The country is bordered to the north by Myanmar and Laos, to the east by Laos and Cambodia, to the south by the Gulf of Thailand and Malaysia, and to the west by the Andaman Sea and the extremity of Myanmar. Thailand also shares maritime borders with Vietnam to the southeast, and Indonesia and India to the southwest. Bangkok is the nation's capital and largest city. Tai peoples migrated from southwestern China to mainland Southeast Asia from the 11th century. Indianised kingdoms such as the Mon, Khmer Empire and Malay states ruled the region, competing with Thai states such as the Kingdoms of Ngoenyang, Sukhothai, Lan Na and Ayutthaya, which also rivalled each other. European contact began in 1511 with a Portuguese diplomatic mission to Ayutthaya, w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myanmar
Myanmar, ; UK pronunciations: US pronunciations incl. . Note: Wikipedia's IPA conventions require indicating /r/ even in British English although only some British English speakers pronounce r at the end of syllables. As John C. Wells, John Wells explains, the English spellings of both Myanmar and Burma assume a non-rhotic variety of English, in which the letter r before a consonant or finally serves merely to indicate a long vowel: [ˈmjænmɑː, ˈbɜːmə]. So the pronunciation of the last syllable of Myanmar as [mɑːr] or of Burma as [bɜːrmə] by some speakers in the UK and most speakers in North America is in fact a spelling pronunciation based on a misunderstanding of non-rhotic spelling conventions. The final ''r'' in ''Myanmar'' was not intended for pronunciation and is there to ensure that the final a is pronounced with the broad a, broad ''ah'' () in "father". If the Burmese name my, မြန်မာ, label=none were spelled "Myanma" in English, this would b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...
