Sula Dwarf Kingfisher
The Sula dwarf kingfisher (''Ceyx wallacii''), is a species of bird in the family Alcedinidae that is endemic to the Sula Islands in Indonesia. Its natural habitat is subtropical or tropical moist lowland forests. It was formerly considered to be a subspecies of the variable dwarf kingfisher. 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 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.

Richard Bowdler Sharpe
Richard Bowdler Sharpe (22 November 1847 – 25 December 1909) was an English zoologist and ornithologist who worked as curator of the bird collection at the British Museum of natural history. In the course of his career he published several monographs on bird groups and produced a multi-volume catalogue of the specimens in the collection of the museum. He described many new species of bird and also has had species named in his honour by other ornithologists including Sharpe's longclaw (''Macronyx sharpei'') and Sharpe's starling (''Poeoptera sharpii''). Biography Richard was born in London, the first son of Thomas Bowdler Sharpe. His grandfather, Reverend Lancelot Sharpe was Rector of All Hallows Staining. His father was a publisher on Skinner Street and was best known for being the publisher of ''Sharpe's London Magazine'', an illustrated periodical (weekly but monthly from 1847). His care from the age of six was under an aunt, Magdalen Wallace, widow of the headmaster at Gramm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bird
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the ostrich. There are about ten thousand living species, more than half of which are passerine, or "perching" birds. Birds have 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 loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some waterbirds, have further evolved for swimming. B ...

Sula Islands
The Sula Islands Regency ( id, Kabupaten Kepulauan Sula) is one of the regencies in North Maluku province of Indonesia. It covers a land area of 3,338.67 km2 and consists of two of the three large islands comprising the Sula Archipelago, together with minor adjacent islands. These two islands are Sulabesi (formerly Sanama) and Mangoli (formerly Mangole). The third island, Taliabu, was split off from the Sula Islands Regency in 2013 to form a separate regency. Pre-Indonesian Independence saw the Sula Islands also known as the Xulla Islands, with Taliabo as Xulla Taliabo, Sanana as Xulla Bessi, and Mangoli as Xulla Mangola. Administration Sula Islands Regency comprises twelve districts (''kecamatan''), tabulated below with their areas and populations at the 2010 Census and the 2020 Census. The table also includes the locations of the district administrative centres, and the number of villages (rural ''desa'' and urban ''kelurahan'') in each district. History The Dutch built ...

Habitat
In ecology, the term habitat summarises the array of resources, physical and 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 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 light intensity. Biotic factors will include the availability of food and the presence or absence of predators. Every species has particular habitat requirements, with habitat generalist species able to thrive in a wide array of environmental conditions while habitat specialist species requiring a very limited set of factors to survive. The habitat of a species is not necessarily found in a geographical area, it can be the interior ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forest
A forest is an area of land dominated by 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 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 2020'' (FRA 2020) found that forests covered , or approximately 31 percent of the world's land area in 2020. Forests are the predominant terrestrial ecosystem of Earth, and are found around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, Russia, and the United States). The largest share of forests (45 percent) are in th ...

Variable Dwarf Kingfisher
Variable dwarf kingfisher is a common name of a group of kingfishers in the genus, '' 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 kingfisher ...

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. [...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] |
