Black-backed Dwarf Kingfisher
The black-backed dwarf kingfisher (''Ceyx erithaca''), also known as the three-toed kingfisher, is a pocket-sized bird in the 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 migrant that is endemic to parts of the 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 formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae''. He placed it with the other kingfishers in the genus '' Alcedo'' and c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mangaon
Mangaon is a small town (and ''taluka'') in the Konkan region of Maharashtra, India. It is located in the Raigad district, from Alibag, Alibaug headquarters, and from the state capital of Mumbai, towards the Panjim side. 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.

Systema Naturae
' (originally in Latin written ' with the ligature æ) is one of the major works of the Swedish botanist, zoologist and physician Carl Linnaeus (1707–1778) and introduced the Linnaean taxonomy. Although the system, now known as binomial nomenclature, was partially developed by the Bauhin brothers, Gaspard and Johann, Linnaeus was first to use it consistently throughout his book. The first edition was published in 1735. The full title of the 10th edition (1758), which was the most important one, was ' or translated: "System of nature through the three kingdoms of nature, according to classes, orders, genera and species, with characters, differences, synonyms, places". The tenth edition of this book (1758) is considered the starting point of zoological nomenclature. In 1766–1768 Linnaeus published the much enhanced 12th edition, the last under his authorship. Another again enhanced work in the same style and titled "'" was published by Johann Friedrich Gmelin between 1788 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sumatra
Sumatra is one of the Sunda Islands of western Indonesia. It is the largest island that is fully within Indonesian territory, as well as the sixth-largest island in the world at 473,481 km2 (182,812 mi.2), not including adjacent islands such as the Simeulue, Nias, Mentawai, Enggano, Riau Islands, Bangka Belitung and Krakatoa archipelago. Sumatra is an elongated landmass spanning a diagonal northwest–southeast axis. The Indian Ocean borders the northwest, west, and southwest coasts of Sumatra, with the island chain of Simeulue, Nias, Mentawai, and Enggano off the western coast. In the northeast, the narrow Strait of Malacca separates the island from the Malay Peninsula, which is an extension of the Eurasian continent. In the southeast, the narrow Sunda Strait, containing the Krakatoa Archipelago, separates Sumatra from Java. The northern tip of Sumatra is near the Andaman Islands, while off the southeastern coast lie the islands of Bangka and Belitung, Karim ...

Malay Peninsula
The Malay Peninsula (Malay: ''Semenanjung Tanah Melayu'') is a peninsula in Mainland Southeast Asia. The landmass runs approximately north–south, and at its terminus, it is the southernmost point of the Asian continental mainland. The area contains Peninsular Malaysia, Southern Thailand, and the southernmost tip of Myanmar (Kawthaung). The island country of Singapore also has historical and cultural ties with the region. The indigenous people of the peninsula are the Malays, an Austronesian people. The Titiwangsa Mountains are part of the Tenasserim Hills system and form the backbone of the peninsula and the southernmost section of the central cordillera, which runs from Tibet through the Kra Isthmus, the peninsula's narrowest point, into the Malay Peninsula. The Strait of Malacca separates the Malay Peninsula from the Indonesian island of Sumatra, and the south coast is separated from the island of Singapore by the Straits of Johor.

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...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. 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.

Molecular Genetic
Molecular genetics is a sub-field 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. Researchers search for mutations in a gene or induce mutations in a gene to link a gene sequence to a specific phenotype. Molecular genetics is a powerful methodology for linking mutations to genetic conditions that may aid the search for treatments/cures for various genetics diseases. History For molecular genetics to develop as a discipline, several scientific discoveries were necessary. The discovery of DNA as a means to transfer the genetic code of life from one cell ...

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 fu ... [...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 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 Buffon's Natural History ('' 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 Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''. Meantime he wrote two treatises, ''Essai sur l'électricité'' (1781) and ''Physique générale et particuliè ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 oriental 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. The little kingfisher, azure kingfisher, Bismarck kingfisher, silvery kingfisher and Indigo-banded kingfisher were moved from ''Alcedo'' to ''Ceyx''. All except one of the birds in the reconstituted genus have three rather than the usual four toes. The exception is the Sulawesi dwarf kingfisher which retains a vestigial fourth toe. The Moluccan dwarf kingfisher (''Ceyx lepidus'') was previous named the variable d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eleazar Albin
Eleazar Albin ( fl. 1690 – c. 1742)Michael A. Salmon, Peter Marren, Basil Harley. ''The Aurelian Legacy'' (University of California Press, 2000) pp. 109-110. was an English naturalist and watercolourist illustrator who wrote and illustrated a number of books including ''A Natural History of English Insects'' (1720), ''A Natural History of Birds'' (1731–38) and ''A Natural History of Spiders and other Curious Insects'' (1736). He has been described as one of the "great entomological book illustrators of the 18th century". Biography Nothing is known of Albin's early life, though he may have been German-born; he claimed to have been in Jamaica in 1701. In 1708 he is known to have been married and living in Piccadilly, London. According to autobiographical details in ''A Natural History of English Insects'', Albin taught watercolour painting before being instructed in natural history by silk weaver and naturalist Joseph Dandridge.

Latin
Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the Roman Republic it became the dominant language in the Italian region and subsequently throughout the Roman Empire. Even after the fall of Western Rome, Latin remained the common language of international communication, science, scholarship and academia in Europe until well into the 18th century, when other regional vernaculars (including its own descendants, the Romance languages) supplanted it in common academic and political usage, and it eventually became a dead language in the modern linguistic definition. Latin is a highly inflected language, with three distinct genders (masculine, feminine, and neuter), six or seven noun cases (nominative, accusative, genitive, dative, ablative, and vocative), five declensions, four verb conjuga ...
