Arabian Woodpecker
The Arabian woodpecker (''Dendrocoptes dorae'') or Sarat woodpecker, is a bird species of the family Picidae, native to the Sarawat Mountains of Saudi Arabia and Yemen. It is the only woodpecker that breeds on the Arabian Peninsula. This species was first described in 1935 by the American naturalist George Latimer Bates and the Scottish zoologist Norman Boyd Kinnear, the scientific name being proposed by their occasional co-worker, the British Arabist St John Philby, in honour of his wife Dora. Some taxonomic authorities continue to place the species in ''Dendrocopos'', while others place it genus ''Dendropicos''. Description The Arabian woodpecker grows to a length of about . The male has a brownish or pale grey head with a bright red patch on the crown and nape. The back, wings, and tail are olive-grey to brown streaked with white, and the wings are barred with white. The underparts are grey streaked with white and the belly has the central area suffused with red. The female ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George Latimer Bates
George Griswold Latimer Bates (March 21, 1863, Abingdon, Illinois US – January 31, 1940 Chelmsford UK), LL.D., British Ornithologists' Union, M.B.O.U. was an American natural history, naturalist. He lived in central Africa and travelled widely, collecting specimens of natural history from which numerous new species were described. As many as 62 new species of mammals, reptiles and amphibians were described from his collections, including the Goliath frog, the hairy frog, and the Goliath shrew Goliath shrew, ''Crocidura goliath''. He published a ''Handbook of the Birds of West Africa'' (1930) and was compiling a catalogue of the birds of Arabia. Life and work Bates was born near Abingdon, Illinois. He went to school where he learned Latin and became interested in languages. He got an interest in natural history from his teacher Leanna Hague who took the class on botanical trips. He went to study at Lincoln, Illinois, and then transferred to Knox College (Illinois), Knox College ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pandanus
''Pandanus'' is a genus of monocots with about 578 accepted species. They are palm-like, dioecious trees and shrubs native to the Old World tropics and subtropics. Common names include pandan, screw palm and screw pine. The genus is classified in the order Pandanales, family Pandanaceae, and is the largest in the family. Description The species vary in size from small shrubs less than tall, to medium-sized trees tall, typically with a broad canopy, heavy fruit, and moderate growth rate. The trunk is stout, wide-branching, and ringed with many leaf scars. Mature plants can have branches. Depending on the species, the trunk can be smooth, rough, or warty. The roots form a pyramidal tract to hold the trunk. They commonly have many thick stilt roots near the base, which provide support as the tree grows top-heavy with leaves, fruit, and branches. These roots are adventitious and often branched. The top of the plant has one or more crowns of strap-shaped leaves that may be s ...

Taxa Named By George Latimer Bates
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Described In 1935
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] |
Dendrocoptes
''Dendrocoptes'' is a genus of woodpeckers in the (Family (biology), family Picidae) native to Eurasia. Taxonomy The genus ''Dendrocoptes'' was erected by the German ornithologists Jean Cabanis and Ferdinand Heine in 1863 with the middle spotted woodpecker (''Dendrocoptes medius '') as the type species. The name combines the Ancient Greek ''dendron'' meaning "tree" and ''koptō'' meaning "to strike". A 2015 molecular phylogenetic analysis of the nuclear and mitochondrial DNA sequences from pied woodpeckers found that the genus ''Dendrocopos'' was polyphyletic. As part of the reorganisation to create monophyletic genera, three species from ''Dendrocopos'' were moved to the resurrected genus ''Dendrocoptes''. The taxonomic committee of the British Ornithologists' Union recommended an alternative arrangement in which the genera ''Dendrocoptes'' and ''Leiopicus'' were combined into a larger ''Dendropicos''. The yellow-crowned woodpecker (''Leiopicus mahrattensis'') is closely relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Near Threatened
A near-threatened species is a species which has been Conservation status, categorized as "Near Threatened" (NT) by the International Union for Conservation of Nature (IUCN) as that may be vulnerable to Endangered species, endangerment in the near future, but it does not currently qualify for the threatened status. The IUCN notes the importance of reevaluating near-threatened taxon, taxa at appropriate intervals. The rationale used for near-threatened taxa usually includes the criteria of Vulnerable species, vulnerable which are plausible or nearly met, such as reduction in numbers or range. Those designated since 2001 that depend on conservation efforts to not become threatened are no longer separately considered conservation-dependent species. IUCN Categories and Criteria version 2.3 Before 2001, the IUCN used the version 2.3 Categories and Criteria to assign conservation status, which included a separate category for conservation-dependent species ("Conservation Dependen ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partners ...

Charcoal
Charcoal is a lightweight black carbon residue produced by strongly heating wood (or other animal and plant materials) in minimal oxygen to remove all water and volatile constituents. In the traditional version of this pyrolysis process, called charcoal burning, often by forming a charcoal kiln, the heat is supplied by burning part of the starting material itself, with a limited supply of oxygen. The material can also be heated in a closed retort. Modern charcoal briquettes used for outdoor cooking may contain many other additives, e.g. coal. The early history of wood charcoal production spans ancient times, rooted in the abundance of wood in various regions. The process typically involves stacking wood billets to form a conical pile, allowing air to enter through openings at the bottom, and igniting the pile gradually. Charcoal burners, skilled professionals tasked with managing the delicate operation, often lived in isolation to tend their wood piles . Throughout histo ...

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] |
Dracaena (plant)
''Dracaena'' () is a genus of about 200 species of trees and succulent shrubs. The formerly accepted genera '' Pleomele'' and '' Sansevieria'' are now included in ''Dracaena''. In the APG IV classification system, it is placed in the family Asparagaceae, subfamily Nolinoideae (formerly the family Ruscaceae). It has also formerly been separated (sometimes with '' Cordyline'') into the family Dracaenaceae or kept in the Agavaceae (now Agavoideae). The name ''dracaena'' is derived from the romanized form of the Ancient Greek – ''drakaina'', "female dragon". The majority of the species are native to Africa and the Canary Islands, southern Asia through to northern Australia, with two species in tropical Central America. Description Species of ''Dracaena'' have a secondary thickening meristem in their trunk, termed Dracaenoid thickening by some authors, which is quite different from the thickening meristem found in dicotyledonous plants. This characteristic is shared with me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olea
''Olea'' ( ) is a genus of flowering plants in the family Oleaceae. It includes 12 species native to warm temperate and tropical regions of the Middle East, southern Europe, Africa, southern Asia, and Australasia. They are evergreen trees and shrubs, with small, opposite, entire leaves. The fruit is a drupe. Leaves of ''Olea'' contain trichosclereids. For humans, the most important and familiar species is by far the olive (''Olea europaea''), native to the Mediterranean region, Africa, southwest Asia, and the Himalayas, which is the type species of the genus. The native olive (''O. paniculata'') is a larger tree, attaining a height of 15–18 m in the forests of Queensland, and yielding a hard and tough timber. The yet harder wood of the black ironwood ''O. capensis'', an inhabitant of Natal, is important in South Africa. ''Olea'' species are used as food plants by the larvae of some Lepidoptera Lepidoptera ( ) or lepidopterans is an order (biology), order of winged i ...
