Makira Dwarf Kingfisher
The Makira dwarf kingfisher (''Ceyx gentianus'') is a species of bird in the family Alcedinidae that is endemic to Makira Island. Its natural habitat is subtropical or tropical moist lowland forests. This species was formerly considered one of the 15 recognised subspecies of what was then known as the variable dwarf kingfisher (''Ceyx lepidus'' or ''Alcedo lepidus''). A molecular phylogenetic study published in 2013 found that most of the insular subspecies had substantially diverged from one another. The variable dwarf kingfisher was therefore split and 12 of the subspecies, including the Makira dwarf kingfisher, were promoted to species status. The name of the variable dwarf kingfisher was simultaneously changed to the Moluccan dwarf kingfisher. Taxonomy The holotype of ''Ceyx gentiana'' TristramIbis, 1879, p. 438, pl. 11. is held in the vertebrate zoology collection of National Museums Liverpool at World Museum, with accession number NML-VZ T3959.

Henry Baker Tristram
Henry Baker Tristram FRS (11 May 1822 – 8 March 1906) was an English clergyman, Bible scholar, traveller and ornithologist. As a parson-naturalist he was an early, but short-lived, supporter of Darwinism, attempting to reconcile evolution and creation. Biography He was the son of the Rev. Henry Baker Tristram, born at Eglingham vicarage, near Alnwick, Northumberland. He studied at Durham School and Lincoln College, Oxford. In 1846 he was ordained a priest. Diplomatic, scientific and missionary work Tristram was secretary to the governor of Bermuda from 1847 to 1849. He explored the Sahara desert, and in 1858 visited Palestine, returning there in 1863 and 1872, and dividing his time between natural history observations and identifying localities mentioned in the Old and New Testaments. In 1873 he became canon of Durham Cathedral. In 1881 he travelled again to Palestine, the Lebanon, Mesopotamia, and Armenia. He also made a second voyage to Japan to visit his daughter, K ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Makira Island
The island of Makira (previously known as San Cristóbal) is the largest island of Makira-Ulawa Province in Solomon Islands. It is third most populous of the Solomon Islands after Malaita and Guadalcanal, with a population of 55,126 as of 2020. The island is located east of Guadalcanal and south of Malaita. The largest and capital city is Kirakira, Solomon Islands, Kirakira. History The first recorded sighting by Europeans of Makira was by the Spanish expedition of Álvaro de Mendaña de Neira, Álvaro de Mendaña in June 1568. More precisely the sighting and also landing in San Cristóbal was due to a local voyage that set out from Guadalcanal in a small boat, in the accounts the brigantine ''Santiago'', commanded by Alférez (rank), Alférez Hernando Enriquez and having Hernán Gallego as pilot. They charted it as ''San Cristóbal''.Brand, Donald D. ''The Pacific Basin: A History of its Geographical Explorations'' The American Geographical Society, New York, 1967, p.133. E ...

Habitat
In ecology, habitat refers to the array of resources, biotic factors that are present in an area, such as to support the survival and reproduction of a particular species. A species' habitat can be seen as the physical manifestation of its ecological niche. Thus "habitat" is a species-specific term, fundamentally different from concepts such as Biophysical environment, environment or vegetation assemblages, for which the term "habitat-type" is more appropriate. The physical factors may include (for example): soil, moisture, range of temperature, and Luminous intensity, light intensity. Biotic index, Biotic factors include the availability of food and the presence or absence of Predation, predators. Every species has particular habitat requirements, habitat generalist species are able to thrive in a wide array of environmental conditions while habitat specialist species require a very limited set of factors to survive. The habitat of a species is not necessarily found in a ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an ecosystem characterized by a dense ecological community, community of trees. Hundreds of definitions of forest are used throughout the world, incorporating factors such as tree density, tree height, land use, legal standing, and ecological function. The United Nations' Food and Agriculture Organization (FAO) defines a forest as, "Land spanning more than 0.5 hectares with trees higher than 5 meters and a Canopy (biology), canopy cover of more than 10 percent, or trees able to reach these thresholds ''in situ''. It does not include land that is predominantly under agricultural or urban use." Using this definition, ''Global Forest Resources Assessment (FRA), Global Forest Resources Assessment 2020'' found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the largest Terrestrial ecosystem, terrestrial ecosystems of Earth by area, and are found around the globe. 45 percent of forest land is in the Tropical forest, trop ...

Variable Dwarf Kingfisher
Variable dwarf kingfisher is a common name of a group of kingfishers in the genus, ''Ceyx (bird), Ceyx''. The variable dwarf kingfisher (''Ceyx lepidus'' or ''Alcedo lepidus'') formerly included 15 subspecies. A molecular phylogenetic study published in 2013 found that most of the insular subspecies had substantially diverged from one another. The variable dwarf kingfisher was therefore split and 12 of the subspecies were promoted to species status. At the same time the name of the variable dwarf kingfisher was changed to the Moluccan dwarf kingfisher. The species in the group are: * Moluccan dwarf kingfisher, ''Ceyx lepidus'' * Dimorphic dwarf kingfisher, ''Ceyx margarethae'' * Sula dwarf kingfisher, ''Ceyx wallacii'' * Buru dwarf kingfisher, ''Ceyx cajeli'' * Papuan dwarf kingfisher, ''Ceyx solitarius'' * Manus dwarf kingfisher, ''Ceyx dispar'' * New Ireland dwarf kingfisher, ''Ceyx mulcatus'' * New Britain dwarf kingfisher, ''Ceyx sacerdotis'' * North Solomons dwarf kingf ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Moluccan Dwarf Kingfisher
The Moluccan dwarf kingfisher (''Ceyx lepidus''), formerly known as the variable dwarf kingfisher, is a species of bird in the family Alcedinidae. Taxonomy This species was previous named the variable dwarf kingfisher and had 15 recognised subspecies. A molecular phylogenetic study published in 2013 found that most of the taxa had substantially diverged from each other. The species was therefore split and 12 of the subspecies were promoted to species status. At the same time the name was changed to the Moluccan dwarf kingfisher. Some taxonomic authorities further split this species into the Seram dwarf kingfisher, and refer to the other group as the North Moluccan dwarf kingfisher. The Seram dwarf kingfisher is then limited to the southern Moluccas. Distribution This species is endemic to the Moluccas. ...

Holotype
A holotype (Latin: ''holotypus'') is a single physical example (or illustration) of an organism used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany and mycology, an isotype is a duplicate of the holotype, generally pieces from the same individual plant or samples from the same genetic individual. A holotype is not necessarily "ty ...

National Museums Liverpool
National Museums Liverpool, formerly National Museums and Galleries on Merseyside, comprises several museums and art galleries in and around Liverpool in Merseyside, England. All the museums and galleries in the group have free admission. The museum is a non-departmental public body sponsored by the Department for Culture, Media and Sport (DCMS) and an exempt charity under English law. Until 1974 the institutions were under the auspices of the former Liverpool Corporation. The reorganisation of English local government that year resulted in the newly created Merseyside Metropolitan County Council assuming custodianship by mutual agreement with the city authority. In 1978 the Charity Commission transferred to the County Council the trusteeship of the then privately operated Lady Lever Art Gallery and its collection. The Conservative government of Margaret Thatcher subsequently resolved to abolish the Metropolitan Counties and reassign many of their assets to the lower tier City an ...
