Argas Walkerae
''Argas walkerae'' Kaiser & Hoogstraal, 1969, as its common name "fowl tampan" reflects, is a soft-bodied argasid tick primarily parasitizing chickens and other domestic fowl. In South Africa its natural range spans the eastern region of Eastern Cape Province from the warmer coastal regions on the Indian Ocean in the south to the cooler mountainous Drakensberg range in the northeast of the Province, with local distribution more strongly associated with the presence of fowls and wooden fowl houses, than climate alone. The specific epithet honors the scientific contributions of Dr. Jane Brotherton Walker Jane Brotherton Walker (31 January 1925 – 3 April 2009) was a Kenyan-South African scholar in the field of tick taxonomy, particularly in Africa.Ivan G.

Harry Hoogstraal
Harry Hoogstraal (February 24, 1917 Chicago, Illinois – February 24, 1986 Cairo, Egypt) was an American entomologist and parasitologist. He was described as "the greatest authority on ticks and tickborne diseases who ever lived." The American Society of Tropical Medicine and Hygiene's ''Harry Hoogstraal Medal for Outstanding Achievement in Medical Entomology'' honors his contributions to science. Life and work Hoogstraal earned B.A. and M.S. degrees (1938 and 1942) from the University of Illinois at Chicago, before his training was interrupted by World War II to serve as an officer entomologist (1943–1946) in the United States Army. He later received Ph.D. (1959) and D.Sc. (1971) degrees from the London School of Hygiene and Tropical Medicine. As a master's degree candidate at the University of Illinois, he organized and led (1938–1941) four multi-disciplinary biological expeditions into the mountain and desert portions of western and southwestern Mexico. These resulted i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Argasidae
The Argasidae are the family of soft ticks, one of the three families of ticks. The family contains 193 species, although the composition of the genera is less certain, and more study is needed before the genera can become stable. The currently accepted genera are '' Antricola'', '' Argas'', '' Nothoaspis'', ''Ornithodoros'', and '' Otobius''. The Argasidae are very common in South Asia, along with 96 other species of ticks, making South Asia the region with the highest biodiversity of ticks worldwide. Soft ticks are resistant to desiccation and can live for several years in arid Aridity is the condition of geographical regions which make up approximately 43% of total global available land area, characterized by low annual precipitation, increased temperatures, and limited water availability.Perez-Aguilar, L.

Tick
Ticks are parasitic arachnids of the order Ixodida. They are part of the mite superorder Parasitiformes. Adult ticks are approximately 3 to 5 mm in length depending on age, sex, and species, but can become larger when engorged. Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are around 100 million years old, and come from the Cretaceous period. Ticks are widely distributed around the world, especially in warm, humid climates. Ticks belong to two major families: the Ixodidae, or hard ticks, and the Argasidae, or soft ticks. '' Nuttalliella'', a genus of tick from southern Africa, is the only member of the family Nuttalliellidae, and represents the most primitive living lineage of ticks. Adults have ovoid/pear-shaped bodies (idiosomas) which become engorged with blood when they feed, and eight legs. Their cephalotho ...

Chickens
The chicken (''Gallus gallus domesticus'') is a domesticated subspecies of the red junglefowl (''Gallus gallus''), originally native to Southeast Asia. It was first domesticated around 8,000 years ago and is now one of the most common and widespread domesticated animals in the world. Chickens are primarily kept for their meat and eggs, though they are also kept as pets. As of 2023, the global chicken population exceeds 26.5 billion, with more than 50 billion birds produced annually for consumption. Specialized breeds such as broilers and laying hens have been developed for meat and egg production, respectively. A hen bred for laying can produce over 300 eggs per year. Chickens are social animals with complex vocalizations and behaviors, and feature prominently in folklore, religion, and literature across many societies. Their economic importance makes them a central component of global animal husbandry and agriculture. Nomenclature Terms for chickens include: * ' ...

Fowl
Fowl are birds belonging to one of two biological orders, namely the gamefowl or landfowl ( Galliformes) and the waterfowl ( Anseriformes). Anatomical and molecular similarities suggest these two groups are close evolutionary relatives; together, they form the fowl clade which is scientifically known as Galloanserae or Galloanseres (initially termed Galloanseri) (Latin ''gallus'' ("rooster") + ''ānser'' ("goose")). This clade is also supported by morphological and DNA sequence data as well as retrotransposon presence/absence data. Terminology As opposed to "fowl", " poultry" is a term for any kind of domesticated bird or bird captive-raised for meat, eggs, or feathers; ostriches, for example, are sometimes kept as poultry, but are neither gamefowl nor waterfowl. In colloquial speech, however, the term "fowl" is often used near-synonymously with "poultry", and many languages do not distinguish between "poultry" and "fowl". Nonetheless, the fact that the Galliformes and An ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eastern Cape Province
The Eastern Cape ( ; ) is one of the nine provinces of South Africa. Its capital is Bhisho, and its largest city is Gqeberha (Port Elizabeth). Due to its climate and nineteenth-century towns, it is a common location for tourists. It is also known for having been home to many anti-apartheid activists, including Nelson Mandela. The second largest province in the country (at 168,966 km2) after the Northern Cape, it was formed in 1994 out of the Xhosa people, Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area, which was known as the Xhosa Kingdom, began to be settled by Europeans who originally came from England, Scotland and Ireland. Eastern Cape is the only province in South Africa were the number of Black Africans declined from 86.6% to 85.7% since Apartheid ended in 1994. History The Eastern Cape p ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or approximately 20% of the water area of Earth#Surface, Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia (continent), Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. The Indian Ocean has large marginal or regional seas, including the Andaman Sea, the Arabian Sea, the Bay of Bengal, and the Laccadive Sea. Geologically, the Indian Ocean is the youngest of the oceans, and it has distinct features such as narrow continental shelf, continental shelves. Its average depth is 3,741 m. It is the warmest ocean, with a significant impact on global climate due to its interaction with the atmosphere. Its waters are affected by the Indian Ocean Walker circulation, resulting in unique oceanic currents and upwelling patterns. The Indian Ocean is ecologically diverse, with important ecosystems such ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Specific Epithet (zoology)
In zoological nomenclature, the specific name (also specific epithet, species epithet, or epitheton) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Etymology Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the sp ...
