Grey Wagtail
The grey wagtail (''Motacilla cinerea'') is a member of the wagtail family, Motacillidae, measuring around 18–19 cm overall length. The species looks somewhat similar to the yellow wagtail but has the yellow on its underside restricted to the throat and vent. Breeding males have a black throat. The species is widely distributed, with several populations breeding in Eurosiberia and migrating to tropical regions in Asia and Africa. The species is always associated with running water when breeding, although they may use man-made structures near streams for the nest. Outside the breeding season, they may also be seen around lakes, coasts and other watery habitats. Like other wagtails, they frequently wag their tail and fly low with undulations and they have a sharp call that is often given in flight. Taxonomy and systematics The binomial name of the grey wagtail ''Motacilla cinerea'' was introduced by Marmaduke Tunstall in his 1771 publication ''Ornithologia Britannica''. '' ...

Hyderabad
Hyderabad ( ; , ) is the capital and largest city of the Indian state of Telangana and the ''de jure'' capital of Andhra Pradesh. It occupies on the Deccan Plateau along the banks of the Musi River, in the northern part of Southern India. With an average altitude of , much of Hyderabad is situated on hilly terrain around artificial lakes, including the Hussain Sagar lake, predating the city's founding, in the north of the city centre. According to the 2011 Census of India, Hyderabad is the fourth-most populous city in India with a population of residents within the city limits, and has a population of residents in the metropolitan region, making it the sixth-most populous metropolitan area in India. With an output of 74 billion, Hyderabad has the fifth-largest urban economy in India. Muhammad Quli Qutb Shah established Hyderabad in 1591 to extend the capital beyond the fortified Golconda. In 1687, the city was annexed by the Mughals. In 1724, Asaf Jah I, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protein Subunit
In structural biology, a protein subunit is a polypeptide chain or single protein molecule that assembles (or "''coassembles''") with others to form a protein complex. Large assemblies of proteins such as viruses often use a small number of types of protein subunits as building blocks. A subunit is often named with a Greek or Roman letter, and the numbers of this type of subunit in a protein is indicated by a subscript. For example, ATP synthase has a type of subunit called α. Three of these are present in the ATP synthase molecule, leading to the designation α3. Larger groups of subunits can also be specified, like α3β3-hexamer and c-ring. Naturally-occurring proteins that have a relatively small number of subunits are referred to as oligomeric.Quote: ''Oligomer molecule: A molecule of intermediate relative molecular mass, the structure of which essentially comprises a small plurality of units derived, actually or conceptually, from molecules of lower relative molecular ...

Isospora
''Isospora'' is a genus of internal parasites in the subclass Coccidia. It is responsible for the condition isosporiasis, which causes acute, non-bloody diarrhoea in immunocompromised individuals. Taxonomy At least 248 species were originally described in this genus. For instance, the house sparrow The house sparrow (''Passer domesticus'') is a bird of the Old World sparrow, sparrow family Passeridae, found in most parts of the world. It is a small bird that has a typical length of and a mass of . Females and young birds are coloured pale ... has 12 species of ''Isospora''. However, most species are little studied, and some authors doubt whether all should be recognized as distinct species. In 2005, all former ''Isospora'' species that infect mammalian hosts were reclassified as members of the genus '' Cystoisospora'', a member of the Sarcocystidae family.

Borrelia
''Borrelia'' is a genus of bacteria of the spirochete phylum. Several species cause Lyme disease, also called Lyme borreliosis, a zoonotic, vector-borne disease transmitted by ticks. Other species of ''Borrelia'' cause relapsing fever, and are transmitted by ticks or lice, depending on the species of bacteria. A few ''Borrelia'' species as ''Candidatus'' Borrelia mahuryensis harbor intermediate genetic features between Lyme disease and relapsing fever ''Borrelia''. The genus is named after French biologist Amédée Borrel (1867–1936), who first documented the distinction between a species of ''Borrelia'', ''B. anserina'', and the other known type of spirochete at the time, ''Treponema pallidum''. This bacterium must be viewed using dark-field microscopy, which make the cells appear white against a dark background. ''Borrelia'' species are grown in Barbour-Stoenner-Kelly medium. Of 52 known species of ''Borrelia'', 20 are members of the Lyme disease group (with an additional 3 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ixodes Ricinus
''Ixodes ricinus'', the castor bean tick, is a chiefly European species of hard-bodied tick. It may reach a length of when engorged with a blood meal, and can transmit both bacterial and viral pathogens such as the causative agents of Lyme disease and tick-borne encephalitis. Description In common with other species of '' Ixodes'', ''I. ricinus'' has no eyes and is not ornate; it has no festoons (wrinkles along the posterior margin). The palpi are longer than they are wide, and an anal groove is above the anus. It has a hard dorsal shield which covers the entire opisthosoma (abdomen), but only part of it in females and nymphs. ''I. ricinus'' is the largest of the three common species of ''Ixodes'' in the British Isles (the other two being '' I. canisuga'', the British dog tick, and '' I. trianguliceps'', the vole tick). Adult males are long, and unfed nymphs are long; females are long before feeding and long when engorged. Distribution ''Ixodes ric ...

Interspecific Feeding
Interspecific feeding refers to behaviour reported in wild animals, particularly birds where adults of one species feed the young of another species. This usually excludes the case of birds feeding brood parasites. The behaviour has been of theoretical interest since it appears to be provide little evolutionary benefit to the feeding bird. Some researchers have suggested that it is mainly male birds that are lured into feeding a fledgling that begs Such behaviour is also related to alloparenting, cross-fostering and brood adoption Adoption is a process whereby a person assumes the parenting of another, usually a child, from that person's biological or legal parent or parents. Legal adoptions permanently transfer all rights and responsibilities, along with filiation, fro .... Several situations have been suggested that lead to this including: # Bird raised in a mixed clutch # Original nest and brood of bird destroyed # Nests in very close proximity # Calling of young birds s ...

White-throated Dipper
The white-throated dipper (''Cinclus cinclus''), also known as the European dipper or just dipper, is an aquatic passerine bird found in Europe, Middle East, Central Asia and the Indian Subcontinent. The species is divided into several subspecies, based primarily on colour differences, particularly of the pectoral band. The white-throated dipper is Norway's national bird. Taxonomy and systematics The white-throated dipper was described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Sturnus cinclus''. The current genus ''Cinclus'' was introduced by the German naturalist Moritz Balthasar Borkhausen in 1797. The name ''cinclus'' is from the Ancient Greek word that was used to describe small tail-wagging birds that resided near water. Of the five species now placed in the genus, a molecular genetic study has shown that the white-throated dipper is most closely related to the other Eurasian species, the ...

Grey Wagtail- Breeding Male I IMG 6705
Grey (more common in British English) or gray (more common in American English) is an intermediate color between black and white. It is a neutral or achromatic color, meaning literally that it is "without color", because it can be composed of black and white. It is the color of a cloud-covered sky, of ash and of lead. The first recorded use of ''grey'' as a color name in the English language was in 700 CE.Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 196 ''Grey'' is the dominant spelling in European and Commonwealth English, while ''gray'' has been the preferred spelling in American English; both spellings are valid in both varieties of English. In Europe and North America, surveys show that grey is the color most commonly associated with neutrality, conformity, boredom, uncertainty, old age, indifference, and modesty. Only one percent of respondents chose it as their favorite color. Etymology ''Grey'' comes from the Middle English ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viktor Von Tschusi Zu Schmidhoffen
Viktor von Tschusi zu Schmidhoffen (28 December 1847 – 5 March 1924) was an Austrian ornithologist. Biography Tschusi was born on 28 December 1847 in the Smíchov district of Prague. His father was a former officer in the Austro-Hungarian Army from a noble family of Tyrol, and Tschusi held the title of Reichsritter. Tschusi's father, and his mother Josephine, inspired an early interest in natural history. Tschusi attended gymnasium school at a Jesuit college at Kalksburg, near Vienna. He began his scientific studies under a private tutor when his family moved to Krems an der Donau, and to Schloss Arntsdorf after his father's death when he was 17. Tschusi learned to prepare bird specimens from a preparator at the Imperial Natural History Museum, and became skilled at collecting and preparing bird specimens. From 1868 to 1870, he travelled extensively in Austria, Bohemia, northern Italy, northern Germany, and Heligoland, meeting other ornithologists and visiting important bi ...
