Ammomanes Grayi
Gray's lark (''Ammomanopsis grayi'') is a species of lark in the family Alaudidae. It is found in south-western Africa in its natural habitat of hot deserts. Taxonomy and systematics Gray's lark was originally described as a species within the genus ''Alauda''. It was then placed in the sister genus ''Ammomanes'' until re-classified in 2009 by the IOC into the monotypic genus ''Ammomanopsis''. Some authorities still consider the species as ''Ammomanes grayi''. Other names for Gray's lark include Gray's desert lark and Gray's sand lark. Subspecies Two subspecies are recognized: * ''A. g. hoeschi'' - ( Niethammer, 1955): Found in north-western Namibia and south-western Angola * ''A. g. grayi'' - ( Wahlberg, 1855): Found in west-central and south-western Namibia References Gray's lark Birds of Southern Africa Gray's lark Gray's lark Gray's lark (''Ammomanopsis grayi'') is a species of lark in the family Alaudidae.

Valentin Bianchi
Valentin Lvovich Bianchi (Russian: Валенти́н Льво́вич Биа́нки; 18 February 1857 – 10 January 1920) was a Russian ornithologist. He is honoured in the common and scientific names of Bianchi's warbler (''Seicercus valentini''), described by Ernst Hartert. Of Italian descent, Bianchi graduated from the Imperial Military Medical Academy as a military doctor (1882). There years later, he was working as a general practitioner in the rural district of Staritsa, when Professor Eduard Brandt, learning about his interest in ornithology, invited him to join the staff of his alma mater. He moved to the Zoological Museum in 1887. Bianchi was the Head of the Department of Ornithology at the Imperial Academy of Sciences from 1896 to 1920. He worked mainly on birds from Middle and Central Asia. An active member of the Russian Geographical Society, he took part in its major enterprises such as the Toll Expedition (1900) and the Kamchatka Expedition of 1908. His so ...

Johan August Wahlberg
Johan August Wahlberg (9 October 1810, in Lackarebäck, Sweden – 6 March 1856, in Lake Ngami, Bechuanaland) was a Swedish naturalist and explorer. Wahlberg started studying chemistry at the University of Uppsala in 1829, and later forestry, agronomy and natural science, graduating from the Swedish Forestry Institute in 1834. In 1832 he joined Professor Carl Henrik Boheman, a famous entomologist, on a collecting trip to Norway. In 1833 and 1834 he travelled in Sweden and Germany on forestry research projects. He joined the Office of Land Survey and was appointed an engineer in 1836, becoming an instructor at the Swedish Land Survey College. He travelled in southern Africa between 1838 and 1856, sending thousands of natural history specimens back to Sweden. He was exploring the Okavango area along with Frederick Joseph Green (1829-1876) when he was killed, along the Thamalakane river about 10 km northwest of Maun in today's Botswana, by a wounded elephant.

Lark
Larks are passerine birds of the family Alaudidae. Larks have a cosmopolitan distribution with the largest number of species occurring in Africa. Only a single species, the horned lark, occurs in North America, and only Horsfield's bush lark occurs in Australia. Habitats vary widely, but many species live in drier regions. When the word "lark" is used without specification, it often refers to the Eurasian skylark ''(Alauda arvensis)''. Taxonomy and systematics The family Alaudidae was introduced in 1825 by the Irish zoologist Nicholas Aylward Vigors as a subfamily Alaudina of the finch family Fringillidae. Larks are a well-defined family, partly because of the shape of their . They have multiple Scute#Birds, scutes on the hind side of their tarsi, rather than the single plate found in most songbirds. They also lack a pessulus, the bony central structure in the syrinx of songbirds. They were long placed at or near the beginning of the songbirds or oscines (now often called Pas ...

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] |
Desert
A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or Semi-arid climate, semi-arid. This includes much of the Polar regions of Earth, polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location. Deserts are formed by weathering processes as large variations in temperature between day and night strain the Rock (geology), rocks, which consequently break in pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting frag ...

Alauda
''Alauda'' is a genus of larks found across much of Europe, Asia and in the mountains of north Africa, and one of the species (the Raso lark) endemic to the islet of Raso in the Cape Verde Islands. Further, at least two additional species are known from the fossil record. The current genus name is from Latin ''alauda'', "lark". Pliny the Elder thought the word was originally of Celtic origin. Taxonomy and systematics The genus ''Alauda'' was introduced by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae''. The type species In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the spe ... was subsequently designated as the Eurasian skylark.

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 ...

Subspecies
In Taxonomy (biology), biological classification, subspecies (: subspecies) is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (Morphology (biology), morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated as subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific name, infraspecific ranks, such as variety (botany), variety, may be named. In bacteriology and virology, under standard International Code of Nomenclature of Prokaryotes, bacterial nomenclature and virus clas ...

Günther Niethammer
Günther Theodor Niethammer (28 September 1908 Waldheim, Saxony, Waldheim – 14 January 1974, Kottenforst) was a German ornithologist who served during the Second World War with the Nazi Waffen-SS at various places including the Auschwitz concentration camp where he conducted studies on birds. Life and work Niethammer was born in Waldheim, the eighth son of Konrad Niethammer, a paper manufacturer (owner of Kübler & Niethammer paper mills) and politician. After studying zoology at Tübingen in 1927 he moved to Leipzig in 1929 and then worked on the anatomy of the avian crop under Johannes Meisenheimer, J. Meisenheimer. Through Hans Kummerlöwe, also in Leipzig, he met Erwin Stresemann who gave him the task of compiling the ''Handbuch der Deutschen Vogelkunde''. The publication of the first volume led to a position as a curator at the Museum Koenig in Bonn from 1937 and he continued to work on the remaining two volumes, the last published in 1942. In 1937, Niethammer joined the Na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birds Of Southern Africa
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.
