Oriental Dwarf Kingfisher
The black-backed dwarf kingfisher (''Ceyx erithaca''), also known as the three-toed kingfisher, is a pocket-sized bird in the Family (biology), family Alcedinidae. It was formerly considered as conspecific with the rufous-backed dwarf kingfisher and together the species complex was known by the English name "oriental dwarf kingfisher". This tropical kingfisher is a partial Bird migration, migrant that is Endemism, endemic to parts of the Indian subcontinent, Indian Subcontinent and Mainland Southeast Asia. It resides in lowland forests, typically near streams or ponds, where it feeds upon insects, spiders, worms, crabs, fish, frogs, and lizards. It is easily distinguishable from other birds in its range due to its red bill, yellow-orange underparts, lilac-rufous upperparts, and blue-black back. Taxonomy and systematics The black-backed kingfisher was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae ...

Mangaon
Mangaon is a Village and ''tehsil'' (council) in the Konkan Division, India. It is located in the Raigad district, from Alibaug headquarters, and from the capital city of Bombay (Mumbai). The area is located towards the Panjim side of Goa. History Mangaon has been identified with the site of the ancient village of ''Kothuraka'', mentioned in the so-called Kothuraka grant of the 5th-century Vakataka ruler Pravarasena II. The same inscription also mentions a place called ''Maṇḍuki-grāma'', which has been identified with the nearby village of Mandgaon, 3 km north of Mangaon. Industrial development The Vile-Bhagad M.I.D.C. industrial zone, which is located in Mangaon, was previously in a dilapidated state due to a lack of investment. Lately, however, the zone has increased in importance and houses several steel companies, including POSCO LTD. Moreover, Tata Power Ltd.'s hydroelectric project has greatly reduced the need for additional energy generation in the Ma ...

Mainland Southeast Asia
Mainland Southeast Asia (historically known as Indochina and the Indochinese Peninsula) is the continental portion of Southeast Asia. It lies east of the Indian subcontinent and south of Mainland China and is bordered by the Indian Ocean to the west and the Pacific Ocean to the east. It includes the countries of Cambodia, Laos, Myanmar, Singapore, Thailand and Vietnam as well as Peninsular Malaysia. The term ''Indochina'' (originally ''Indo-China'') was coined in the early nineteenth century, emphasizing the historical cultural influence of Indian and Chinese civilizations on the region. The term was later adopted as the name of the colony of French Indochina (present-day Cambodia, Laos, and Vietnam). Today, the term "Mainland Southeast Asia" is more commonly used, in contrast to Maritime Southeast Asia for the island groups off the coast of the peninsula. Terminology In Indian sources, the earliest name connected with Southeast Asia is . Another possible early name of mai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Introgression
Introgression, also known as introgressive hybridization, in genetics is the transfer of genetic material from one species into the gene pool of another by the repeated backcrossing of an interspecific hybrid with one of its parent species. Introgression is a long-term process, even when artificial; it may take many hybrid generations before significant backcrossing occurs. This process is distinct from most forms of gene flow in that it occurs between two populations of different species, rather than two populations of the same species. Introgression also differs from simple Hybridization (biology), hybridization. Simple hybridization results in a relatively even mixture; gene and allele frequencies in the first generation will be a uniform mix of two parental species, such as that observed in mules. Introgression, on the other hand, results in a complex, highly variable mixture of genes, and may only involve a minimal percentage of the donor genome. Definition Introgression or i ...

Molecular Genetic
Molecular genetics is a branch of biology that addresses how differences in the structures or expression of DNA molecules manifests as variation among organisms. Molecular genetics often applies an "investigative approach" to determine the structure and/or function of genes in an organism's genome using genetic screens. The field of study is based on the merging of several sub-fields in biology: classical Mendelian inheritance, cellular biology, molecular biology, biochemistry, and biotechnology. It integrates these disciplines to explore things like genetic inheritance, gene regulation and expression, and the molecular mechanism behind various life processes. A key goal of molecular genetics is to identify and study genetic mutations. Researchers search for mutations in a gene or induce mutations in a gene to link a gene sequence to a specific phenotype. Therefore molecular genetics is a powerful methodology for linking mutations to genetic conditions that may aid the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Commission On Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries. Organization The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. Members are elected by the Section of Zoological Nomenclature, established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years. Members can be re-elected up to a total of three full six-year terms in a row. After 18 continuous years of elected service, a break of at least three years is prescribed before the member can stand again for election. Activities Since 2014, the work of the Commission is supported by a small secretariat based at the National University of Singapore, in Singapore. Previously, the secretariat was based in London and f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernard Germain De Lacépède
Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French natural history, naturalist and an active freemason. He is known for his contribution to the Comte de Buffon's great work, the ''Histoire Naturelle''. Biography Lacépède was born at Agen in Guienne. His education was carefully conducted by his father, and the early perusal of Georges-Louis Leclerc, Comte de Buffon, Buffon's Natural History (''Histoire naturelle, Histoire naturelle, générale et particulière'') awakened his interest in that branch of study, which absorbed his chief attention. His leisure he devoted to music, in which, besides becoming a good performer on the piano and organ, he acquired considerable mastery of composition, two of his operas (which were never published) meeting with the high approval of Christoph Willibald Gluck, Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''.

Ceyx (bird)
''Ceyx'' ( ) is an Old World genus of river kingfishers. These kingfishers are found from South East Asia to the Solomon Islands. The genus was introduced by the French naturalist Bernard Germain de Lacépède in 1799, and derives its name from the Greek myth of Alcyone and Ceyx. The type species is the black-backed dwarf kingfisher (''Ceyx erithaca''). A molecular phylogenetic study of the alcedinine kingfishers published in 2007 found that the genera as then defined did not form monophyletic groups. The species were subsequently rearranged into four monophyletic genera.

Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area around Rome, Italy. Through the expansion of the Roman Republic, it became the dominant language in the Italian Peninsula and subsequently throughout the Roman Empire. It has greatly influenced many languages, Latin influence in English, including English, having contributed List of Latin words with English derivatives, many words to the English lexicon, particularly after the Christianity in Anglo-Saxon England, Christianization of the Anglo-Saxons and the Norman Conquest.

Binomial Name
In taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Latin grammatical forms, although they can be based on words from other languages. Such a name is called a binomial name (often shortened to just "binomial"), a binomen, name, or a scientific name; more informally, it is also called a Latin name. In the International Code of Zoological Nomenclature (ICZN), the system is also called nomenclature, with an "n" before the "al" in "binominal", which is a typographic error, meaning "two-name naming system". The first part of the name – the '' generic name'' – identifies the genus to which the species belongs, whereas the second part – the specific name or specific epithet – distinguishes the species within the genus. For example, modern humans belong to the genus ''Homo'' and within this genus to the species ''Hom ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alcedo
''Alcedo'' is a genus of birds in the kingfisher subfamily Alcedininae. The genus was introduced by Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, 10th edition of his ''Systema Naturae''. The type species is the common kingfisher (''Alcedo ispida'', now ''Alcedo atthis ispida''). ''Alcedo'' is the Latin for "kingfisher". Species The genus contains the following eight species: Unlike many kingfishers, all members of ''Alcedo'' are specialist fish-eaters. They all have some blue feathers on their upper-parts and most species have a black bill. Except for the cerulean kingfisher they all have some rufous in their plumage. The female generally has more red on the lower mandible than the male. The smallest species is the cerulean kingfisher which is around in length; much the largest is Blyth's kingfisher with a length of .

Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...
