White-crowned Shama
The white-crowned shama (''Copsychus stricklandii'') is a medium sized passerine bird in the Old World flycatcher family Muscicapidae. It is endemic to the Southeast Asian island of Borneo. The Maratua shama was formerly treated as a subspecies. Taxonomy It is closely related to the white-rumped shama (''Copsychus malabaricus''), and has in the past been sometimes considered a subspecies of that species. The Maratua shama was formerly treated as a subspecies but is now treated as a separate species based on the differences in morphology and mitochondrial DNA sequences. The white-crowned shama is now monotypic: no subspecies are recognised. The specific name was bestowed in honour of Hugh Edwin Strickland Description The white-crowned shama is about in length (including a tail in adult males) and in weight. Mainly blue-black upperparts contrast with orange-rufous underparts. It has a white rump and black throat. It is largely similar in appearance to the white-rumped shama s ...

James Motley
James Motley (2 May 1822 – 1 May 1859) was a Yorkshireman closely associated with South Wales and Borneo. Life Born in Leeds, the son of Thomas Motley (1781–1863) and Caroline Osburn (1795–1869), sister of noted Egyptologist William Osburn. James was educated at St Peter's School, York and St John's College, Cambridge. He spent at least some of his youth in South Wales where his father, a woolstapler, had investments in iron, coal, and tin works, being an early partner in the Maesteg Ironworks, Yskyn Colliery at Briton Ferry, Margam tinworks, and the Dafen tinworks at Llanelli. He published a volume of poetry ''Tales of Cymry'' in 1848. He worked as an engineer and manager (at Tewgoed (or 'Terrgoed') Colliery at Cwmavon); then underground surveyor to William Chambers of Llanelli; and finally, at Abercrave colliery, iron works, iron mines, and limestone quarries while maintaining an active interest in natural history, especially botany (he left a herbarium at the Roya ...

Mitochondrial
A mitochondrion () is an organelle found in the cells of most eukaryotes, such as animals, plants and fungi. Mitochondria have a double membrane structure and use aerobic respiration to generate adenosine triphosphate (ATP), which is used throughout the cell as a source of chemical energy. They were discovered by Albert von Kölliker in 1857 in the voluntary muscles of insects. The term ''mitochondrion'', meaning a thread-like granule, was coined by Carl Benda in 1898. The mitochondrion is popularly nicknamed the "powerhouse of the cell", a phrase popularized by Philip Siekevitz in a 1957 ''Scientific American'' article of the same name. Some cells in some multicellular organisms lack mitochondria (for example, mature mammalian red blood cells). The multicellular animal '' Henneguya salminicola'' is known to have retained mitochondrion-related organelles despite a complete loss of their mitochondrial genome. A large number of unicellular organisms, such as microsporidia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Endemic Birds Of Borneo
The island of Borneo, located in southeast Asia at the southern edge of the South China Sea, is home to one endemic bird Family (biology), family, three endemic bird genera and 61 endemic bird species. All but one of the latter are forest dwellers, with most restricted to the spine of hills and mountains running down the middle of the island. The avian endemism has been shaped by the island's geological history. Borneo sits on a continental shelf. During glacial periods, when water levels were lower, Borneo was linked with other islands on the shelf and with the Malay Peninsula in a large landmass known as Sundaland. This allowed bird species to move freely throughout the region until the waters rose again as the glaciers melted. Separated from their relatives by the sea, some of these species evolved over millennia into the endemics now found on the island. BirdLife International has designated the mountainous central spine of the island as an Endemic Bird Area (EBA) because of th ...

Copsychus
The magpie-robins or shamas (from ''shama'', Bengali and Hindi for ''C. malabaricus'') are medium-sized insectivorous birds (some also eat berries and other fruit) in the genus ''Copsychus''. They were formerly in the thrush family Turdidae, but are now treated as part of the Old World flycatcher family Muscicapidae. They are garden- and forest-dwelling species found in Africa and Asia. The genus ''Copsychus'' was introduced by the German naturalist Johann Georg Wagler in 1827. The type species was subsequently designated as the oriental magpie-robin (''Copsychus saularis'') by the English zoologist George Robert Gray in 1840. The name ''Copsychus'' is from the Ancient Greek Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek ... ''kopsukhos'' or ''kopsikhos'', meaning "blackbird". The ...

Aviculture
Aviculture is the practice of keeping and breeding birds, especially of wild birds in captivity. Aviculture Aviculture is the practice of keeping birds (class '' Aves'') in captivity in controlled conditions, normally within the confines of a cage or an aviary. Some reasons for aviculture are: breeding birds as a hobby, a business like a zoo, or sometimes for research and conservation purposes to preserve and protect some endangered avian species that are at risk due to habitat destruction, the illegal wildlife trade, diseases, and natural disasters. Aviculture encourages conservation, provides education about avian species, provides companion birds for the public, and includes research on avian behaviour. Popular birds people like to keep and breed include budgerigars, cockatiels, finches, macaws, domestic canaries, columbidae (pigeons and doves), loriini (lories and lorikeets), cockatoos, conures, and African grey parrots.

Flight Feather
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices ( or ), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. The flight feathers of some birds perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on them. Even flightless birds still r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Crown (anatomy)
The crown is the top portion of the head behind the Vertex (anatomy), vertex. The anatomy of the crown varies between different organisms. The human crown is made of three layers of the scalp above the skull. The crown also covers a range of Fibrous joint, bone sutures, and contains blood vessels and branches of the trigeminal nerve. The structure of the human crown provides a protective cavity for the brain and optimizes the crown's ability to ensure the Neocortex#:~:text=The neocortex, also called the,commands, spatial reasoning and language., neocortex is safe. Different parts of the neocortex, such as the frontal lobe and the parietal lobe, are protected by the meninges and bone structures. Other organisms, such as whales, have their Blowhole (anatomy), blowholes on their crown, causing a flattened head shape. Some bird species have a Crest (feathers), crest located on their crown, used for communication and courtship. Macroevolution of the human crown has led to different s ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate 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 hybridization, which include genetic and morph ...

Hugh Edwin Strickland
Hugh Edwin Strickland (2 March 1811 – 14 September 1853) was an English geologist, ornithology, ornithologist, naturalist and systematist. Through the British Association, he proposed a series of rules for the nomenclature of organisms in zoology, known as the Strickland Code, that was a precursor of later codes for nomenclature. Biography Strickland was born at Reighton, in the East Riding of Yorkshire. He was the second son of Henry Eustatius Strickland of Apperley, Gloucestershire, by his wife Mary, daughter of Edmund Cartwright, inventor of the power loom, and grandson of Sir George Strickland, bart., of Boynton, East Riding of Yorkshire, Boynton. In 1827 he was sent as a pupil to Thomas Arnold (1795–1842), a family friend. As a boy he acquired a taste for natural history which dominated his life. He received his early education from private tutors and in 1829 entered Oriel College, Oxford. He attended the anatomical lectures of John Kidd (chemist), John Kidd and the g ...

Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...

White-rumped Shama
The white-rumped shama (''Copsychus malabaricus'') is a passerine bird in the Old World flycatcher family Muscicapidae. Native to densely vegetated habitats in the Indian subcontinent and Southeast Asia, its popularity as a cage-bird and songster has led to it being introduced elsewhere. The Larwo shama, the Kangean shama and the Sri Lanka shama were formerly considered to be conspecific with the white-rumped shama. Taxonomy The white-rumped shama was formally described in 1786 by the Austrian naturalist Giovanni Antonio Scopoli under the binomial name ''Muscicapa malabarica''. Scopoli based his account on "Le gobe-mouches à longue queue de Gingi" that had been described in 1782 by the French naturalist Pierre Sonnerat in the second volume of his book ''Voyage aux Indes orientales et à la Chine''. Sonnerat mentioned that the bird was found on the Malabar Coast of India. The type locality is Mahé. The white-rumped shama is now one of 17 species placed in the genus '' Cops ...

Lewis Llewelyn Dillwyn
Lewis Llewelyn Dillwyn (19 May 1814 – 19 June 1892) was a Welsh industrialist and Liberal politician who served as MP for Swansea for 37 years. Early life Dillwyn was born in Swansea, Wales, the fourth of six children of Lewis Weston Dillwyn and Mary Dillwyn. He had two brothers and three sisters. His grandfather, William Dillwyn, was an American Quaker, who, alongside others such as William Wilberforce had campaigned for the abolition of the slave trade. His father had been sent to Swansea by his father William, to take over the management of the Cambrian Pottery, and lived at Sketty Hall. He was educated at Kilvert's Academy in Bath but, following his father's election to Parliament as one of the two members for Glamorgan in 1832 he and chose to follow a business career by taking over the management of Cambrian Pottery, rather than enter Oriel College, Oxford as had been intended.
