Cervus Nippon Yakushimae
''Cervus'' is a genus of deer that primarily are native to Eurasia, although one species occurs in northern Africa and another in North America. In addition to the species presently placed in this genus, it has included a whole range of other species now commonly placed in other genera. Additionally, the species-level taxonomy is in a state of flux. Taxonomy Genus Until the 1970s, ''Cervus'' also included the members of the genera '' Axis'', ''Dama'', and ''Elaphurus'', and until the late 1980s, it included members of '' Rucervus'' and '' Rusa''. Species In the third edition of '' Mammal Species of the World'' from 2005, only the red deer (''C. elaphus'') and sika deer (''C. nippon'') were recognized as species in the genus ''Cervus''. Genetic and morphological evidence suggest more species should be recognized. For example, the species ''Cervus canadensis'' (elk/wapiti) is considered a separate species.

Cervus Elaphus
The red deer (''Cervus elaphus'') is one of the largest deer species. A male red deer is called a stag or hart, and a female is called a hind. The red deer inhabits most of Europe, the Caucasus Mountains region, Anatolia, Iran, and parts of western Asia. It also inhabits the Atlas Mountains of Northern Africa; its early ancestors are thought to have crossed over to Morocco, then to Algeria, Libya and Tunisia via the Strait of Gibraltar, becoming the only species of true deer (Cervidae) to inhabit Africa. Red deer have been introduced to other areas, including Australia, New Zealand, the United States, Canada, Peru, Uruguay, Chile and Argentina. In many parts of the world, the meat (venison) from red deer is used as a food source. Red deer are ruminants, characterized by a four-chambered stomach. Genetic evidence indicates that the red deer, as traditionally defined, is a species group, rather than a single species, though exactly how many species the group includes remains disp ...

Père David's Deer
The Père David's deer (''Elaphurus davidianus''), also known as the ''milu'' () or elaphure, is a species of deer native to the subtropical river valleys of China. It grazes mainly on grass and aquatic plants. It is the only extant member of the genus ''Elaphurus''. Some experts suggest demoting ''Elaphurus'' to a subgenus of ''Cervus''. Based on genetic comparisons, Père David's deer is closely related to Eld's deer. Père David's deer were hunted almost to extinction in their native China by the late 19th century, but a number were taken to zoos in France and Germany and the deer was bred successfully in captivity. In the early 20th century, the British nobleman and politician Herbrand Russell, 11th Duke of Bedford, acquired a few Père David's deer from the Berlin Zoo and built up a large herd on his estate at Woburn Abbey. In the 1980s, the duke's great-grandson Robin Russell, 14th Duke of Bedford, donated several dozen deer to the Chinese government for reintroducing t ...

Kashmir Stag
The Kashmir stag (''Cervus hanglu hanglu''), also called hangul (), is a subspecies of Central Asian red deer endemic to Kashmir and surrounding areas. It is found in dense riverine forests in the high valleys and mountains of Jammu and Kashmir and northern Himachal Pradesh. In Kashmir, it is found primarily in the Dachigam National Park where it receives protection, and elsewhere it is more at risk. In the 1941s, the population was between 3000 and 5000 individuals, but since then habitat destruction, over-grazing by domestic livestock and poaching have reduced population dramatically. Earlier believed to be a subspecies of red deer (''Cervus elaphus''), a number of mitochondrial DNA genetic studies later had the hangul as a part of the Asian clade of the elk (''Cervus canadensis''). The IUCN and American Society of Mammalogists, however, includes it in the new grouping of Central Asian red deer (''Cervus hanglu''), with the Kashmir stag being the type subspecies (''Cervu ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Bactrian Deer
The Bactrian deer (''Cervus hanglu bactrianus''), also called the Bukhara deer, Bokhara deer, or Bactrian wapiti, is a lowland subspecies of Central Asian red deer native to Central Asia. It is similar in ecology to the related Yarkand deer (''C. h. yarkandensis'') in occupying riparian corridors surrounded by deserts. The subspecies are separated from one another by the Tian Shan Mountains and probably form a primordial subgroup of the red deer. Description This deer is usually ashy-gray with yellowish sheen, and a grayish white rump patch. It also has a slightly marked dorsal stripe and a white margin of the upper lip, lower lip, and chin. The antlers are light in color. Usually, four tines are present, with the absence of bez tines. The fourth tine is better developed than the third. Full-grown individuals, however, have five tines on each antler with a bend after the third tine that is characteristic of most Central Asian red deer subspecies. In contrast to the Yarkand deer ...

Yarkand Deer
The Yarkand deer (''Cervus hanglu yarkandensis''), also known as the Theenivs deer, Tarim deer, or Lop Nor stag, is a subspecies of the Central Asian red deer that is native to the province of Xinjiang, China. It is similar in ecology to the related Bactrian deer (''C. h. bactrianus'') in occupying lowland riparian corridors surrounded by deserts. Both populations are isolated from one another by the Tian Shan Mountains and probably form a primordial subgroup of the Central Asian red deer. Description This deer is light rufous in color with a large light-colored patch, including the tail. Its antlers usually have five tines with a terminal fork pointing forward. The fifth tine is usually larger than the fourth and is inclined inward. Range and habitat The Yarkand deer lives in the Tarim Basin deciduous forests and steppe ecoregion of the Tarim, Kaidu, and Qiemo river basins in China's Xinjiang Autonomous Region (East Turkestan). They are dependent on the lowland riparian cor ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

People's Republic Of China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Caspian Sea
The Caspian Sea is the world's largest inland body of water, often described as the world's largest lake or a full-fledged sea. An endorheic basin, it lies between Europe and Asia; east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau of Western Asia. It covers a surface area of (excluding the highly saline lagoon of Garabogazköl to its east) and a volume of . It has a salinity of approximately 1.2% (12 g/L), about a third of the salinity of average seawater. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the southwest, Iran to the south, and Turkmenistan to the southeast. The sea stretches nearly from north to south, with an average width of . Its gross coverage is and the surface is about below sea level. Its main freshwater inflow, Europe's longest river, the Volga, enters at the shallow north end. Two deep ...

Species Group
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Cervus Canadensis
The elk (''Cervus canadensis''), also known as the wapiti, is one of the largest species within the deer family, Cervidae, and one of the largest terrestrial mammals in its native range of North America and Central and East Asia. The common name of "elk" is open to confusion, as "elk" is the name used in British English for the larger ''Alces alces'', with similar names used by other European languages (German ''Elch'', Swedish ''älg'', and French ''élan''). In North America, the common name for ''Alces alces'' is "moose". The name "wapiti" is sometimes used for ''Cervus canadensis'', which derives from the Shawnee and Cree word ''waapiti'', meaning 'white rump'. Elk range in forest and forest-edge habitat, feeding on grasses, plants, leaves, and bark. Male elk have large antlers which they shed each year. Males also engage in ritualized mating behaviors during the rut, including posturing, antler wrestling (sparring), and ''bugling'', a loud series of vocalizations ...

Morphology (biology)
Morphology is a branch of biology dealing with the study of the form and structure of organisms and their specific structural features. This includes aspects of the outward appearance (shape, structure, colour, pattern, size), i.e. external morphology (or eidonomy), as well as the form and structure of the internal parts like bones and organs, i.e. internal morphology (or anatomy). This is in contrast to physiology, which deals primarily with function. Morphology is a branch of life science dealing with the study of gross structure of an organism or taxon and its component parts. History The etymology of the word "morphology" is from the Ancient Greek (), meaning "form", and (), meaning "word, study, research". While the concept of form in biology, opposed to function, dates back to Aristotle (see Aristotle's biology), the field of morphology was developed by Johann Wolfgang von Goethe (1790) and independently by the German anatomist and physiologist Karl Friedrich Burdach ...

Genetics
Genetics is the study of genes, genetic variation, and heredity in organisms.Hartl D, Jones E (2005) It is an important branch in biology because heredity is vital to organisms' evolution. Gregor Mendel, a Moravian Augustinian friar working in the 19th century in Brno, was the first to study genetics scientifically. Mendel studied "trait inheritance", patterns in the way traits are handed down from parents to offspring over time. He observed that organisms (pea plants) inherit traits by way of discrete "units of inheritance". This term, still used today, is a somewhat ambiguous definition of what is referred to as a gene. Trait inheritance and molecular inheritance mechanisms of genes are still primary principles of genetics in the 21st century, but modern genetics has expanded to study the function and behavior of genes. Gene structure and function, variation, and distribution are studied within the context of the cell, the organism (e.g. dominance), and within the ...
