Indian Roller
The Indian roller (''Coracias benghalensis'') is a bird of the family Coraciidae. It is long with a wingspan of and weighs . The face and throat are pinkish, the head and back are brown, with blue on the rump and contrasting light and dark blue on the wings and tail. The bright blue markings on the wing are prominent in flight. The sexes are similar in appearance. Two subspecies are recognised. The Indian roller occurs widely from West Asia to the Indian subcontinent. Often found perched on roadside trees and wires, it is common in open grassland and scrub forest habitats, and has adapted well to human-modified landscapes. It mainly feeds on insects, especially beetles. The species is best known for the aerobatic displays of males during the breeding season. Adult males and females form pair bonds and raise the young together. The female lays 3–5 eggs in a cavity or crevice, which is lined with a thin mat of straw or feathers. The roller is the state bird of three Indian sta ...

Kanha National Park
Kanha Tiger Reserve, also known as Kanha–Kisli National Park, is one of the tiger reserves of India and the largest national park of the state of Madhya Pradesh. The present-day Kanha area is divided into two protected areas, Hallon and Banjar, of , respectively. Kanha National Park was created on 1 June 1955 and was designated a tiger reserve in 1973. Today, it encompasses an area of in the two districts Mandla and Balaghat. Together with a surrounding buffer zone of and the neighbouring Phen Sanctuary, it forms the Kanha Tiger Reserve, which is one of the biggest in the country. This makes it the largest national park in central India. The park hosts Bengal tiger, Indian leopard, sloth bear, barasingha and dhole. It is also the first tiger reserve in India to officially introduce a mascot, Bhoorsingh the Barasingha. Flora Kanha Tiger Reserve is home to over 1000 species of flowering plants. The lowland forest is a mixture of sal (''Shorea robusta'') and other mixe ...

Joseph Dandridge
Joseph Dandridge (January 1665 Winslow, Buckinghamshire – 23 December 1747 London), was an English silk-pattern designer of Huguenot descent, a natural history illustrator, an amateur naturalist specialising in entomology, and a leading figure in the Society of Aurelians of which he was a founder member. Despite having left no published works, and not being part of the close-knit collectors of the Royal Society, Dandridge is credited by numerous entomologists of his time with having provided invaluable assistance and access to his extensive collections of specimens, and even near the end of his life remaining 'affable and communicative'. The collections spanned, besides insects and arachnids, shells, fossils, birds' eggs and skins, flowering plants, lichens, mosses and fungi. A volume of 119 water-colours by Dandridge dating from before 1710 of the arachnids, accompanied by meticulous notes, is in the Sloane Collection of the British Museum and is designated Sloane MS 3999.

Nuclear DNA
Nuclear DNA (nDNA), or nuclear deoxyribonucleic acid, is the DNA contained within each cell nucleus of a eukaryotic organism. It encodes for the majority of the genome in eukaryotes, with mitochondrial DNA and plastid DNA coding for the rest. It adheres to Mendelian inheritance, with information coming from two parents, one male and one female—rather than matrilineally (through the mother) as in mitochondrial DNA. Structure Nuclear DNA is a nucleic acid, a polymeric biomolecule or biopolymer, found in the nucleus of eukaryotic cells. Its structure is a double helix, with two strands wound around each other, a structure first described by Francis Crick and James D. Watson (1953) using data collected by Rosalind Franklin. Each strand is a long polymer chain of repeating nucleotides. Each nucleotide is composed of a five-carbon sugar, a phosphate group, and an organic base. Nucleotides are distinguished by their bases: purines, large bases that include adenine and guanine; and ...

Assam
Assam (; ) is a state in northeastern India, south of the eastern Himalayas along the Brahmaputra and Barak River valleys. Assam covers an area of . The state is bordered by Bhutan and Arunachal Pradesh to the north; Nagaland and Manipur to the east; Meghalaya, Tripura, Mizoram and Bangladesh to the south; and West Bengal to the west via the Siliguri Corridor, a wide strip of land that connects the state to the rest of India. Assamese and Boro are the official languages of Assam, while Bengali is an additional official language in the Barak Valley. Assam is known for Assam tea and Assam silk. The state was the first site for oil drilling in Asia. Assam is home to the one-horned Indian rhinoceros, along with the wild water buffalo, pygmy hog, tiger and various species of Asiatic birds, and provides one of the last wild habitats for the Asian elephant. The Assamese economy is aided by wildlife tourism to Kaziranga National Park and Manas National Park, which are ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending 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 hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ...

Indochinese Roller
The Indochinese roller (''Coracias affinis'') or Burmese roller, is a member of the roller bird family. It occurs widely from eastern India to Myanmar and Southeast Asia. It is listed as Least Concern on the IUCN Red List. Taxonomy The Indochinese roller was formally described in 1840 by the American naturalist Thomas Horsfield under the binomial name ''Coracias affinis'' based on specimens that had been collected in Assam by the naturalist John McClelland. The specific epithet ''affinis'' is from Latin ''adfinis'' or ''affinis'' meaning "related" or "allied". McClelland has sometimes been credited as the authority but under the rules of the International Code of Zoological Nomenclature Horsfield now receives the credit. The Indochinese roller was formerly considered as a subspecies of the Indian roller because of a narrow hybrid zone in northeast India but a molecular phylogenetic study published in 2018 found that the Indochinese roller was more closely related to the purp ...

Vindhya Range
The Vindhya Range (also known as Vindhyachal) () is a complex, discontinuous chain of mountain ridges, hill ranges, highlands and plateau escarpments in west-central India. Technically, the Vindhyas do not form a single mountain range in the geological sense. The exact extent of the Vindhyas is loosely defined, and historically, the term covered a number of distinct hill systems in central India, including the one that is now known as the Satpura Range. Today, the term principally refers to the escarpment and its hilly extensions that runs north of and roughly parallel to the Narmada River in Madhya Pradesh. Depending on the definition, the range extends up to Gujarat in the west, Uttar Pradesh and Bihar in the north, and Chhattisgarh in the east. The Vindhyas have a great significance in Indian mythology and history. Several ancient texts mention the Vindhyas as the southern boundary of the '' Āryāvarta'', the territory of the ancient Indo-Aryan peoples. Although today I ...

Western Asia
Western Asia, West Asia, or Southwest Asia, is the westernmost subregion of the larger geographical region of Asia, as defined by some academics, UN bodies and other institutions. It is almost entirely a part of the Middle East, and includes Anatolia, the Arabian Peninsula, Iran, Mesopotamia, the Armenian Highlands, the Levant, the island of Cyprus, the Sinai Peninsula, and partly the Caucasus Region ( Transcaucasia). The region is considered to be separated from Africa by the Isthmus of Suez in Egypt, and separated from Europe by the waterways of the Turkish Straits and the watershed of the Greater Caucasus. Central Asia lies to its northeast, while South Asia lies to its east. Twelve seas surround the region (clockwise): the Aegean Sea, the Sea of Marmara, the Black Sea, the Caspian Sea, the Persian Gulf, the Gulf of Oman, the Arabian Sea, the Gulf of Aden, the Red Sea, the Gulf of Aqaba, the Gulf of Suez, and the Mediterranean Sea. Western Asia covers an area of , with a ...

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 fun ...

Bengal
Bengal ( ; bn, বাংলা/বঙ্গ, translit=Bānglā/Bôngô, ) is a geopolitical, cultural and historical region in South Asia, specifically in the eastern part of the Indian subcontinent at the apex of the Bay of Bengal, predominantly covering present-day Bangladesh and the Indian state of West Bengal. Geographically, it consists of the Ganges-Brahmaputra delta system, the largest river delta in the world and a section of the Himalayas up to Nepal and Bhutan. Dense woodlands, including hilly rainforests, cover Bengal's northern and eastern areas, while an elevated forested plateau covers its central area; the highest point is at Sandakphu. In the littoral southwest are the Sundarbans, the world's largest mangrove forest. The region has a monsoon climate, which the Bengali calendar divides into six seasons. Bengal, then known as Gangaridai, was a leading power in ancient South Asia, with extensive trade networks forming connections to as far away as Roman Egy ...

Madras Presidency
The Madras Presidency, or the Presidency of Fort St. George, also known as Madras Province, was an administrative subdivision (presidency) of British India. At its greatest extent, the presidency included most of southern India, including the whole of the Indian states of Tamil Nadu, Andhra state and some parts of Kerala, Karnataka, Odisha and the union territory of Lakshadweep. The city of Madras was the winter capital of the Presidency and Ootacamund or Ooty, the summer capital. The coastal regions and northern part of Island of Ceylon at that time was a part of Madras Presidency from 1793 to 1798 when it was created a Crown colony. Madras Presidency was neighboured by the Kingdom of Mysore on the northwest, Kingdom of Cochin on the southwest, and the Kingdom of Hyderabad on the north. Some parts of the presidency were also flanked by Bombay Presidency ( Konkan) and Central Provinces and Berar ( Madhya Pradesh). In 1639, the English East India Company purchased the v ...
