Pigeon Control
Feral pigeons (''Columba livia domestica'' or ''Columba livia forma urbana''), also called city doves, city pigeons, or street pigeons,Nagy, Kelsi, and Johnson, Phillip David. ''Trash animals: how we live with natures filthy, feral, invasive, and unwanted species''. Minneapolis (Minn.), University of Minnesota Press, 2013.Blechman, Andrew D. ''Pigeons: The Fascinating Saga of the World’s Most Revered and Reviled Bird'', St Lucia, Qld., University of Queensland Press, 2007. are descendants of domestic pigeons (''Columba livia domestica'') that have returned to the wild. The domestic pigeon was originally bred from the wild rock dove, which naturally inhabits sea-cliffs and mountains. Rock, domestic, and feral pigeons are all the same species and will readily interbreed. Feral pigeons find the ledges of buildings to be a substitute for sea cliffs, have become adapted to urban life, and are abundant in towns and cities throughout much of the world. Owing to their abilities to crea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN Red List Of Threatened Species
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the International Union for Conservation of Nature, IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to International Unio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Livestock
Livestock are the domesticated animals raised in an agricultural setting to provide labor and produce diversified products for consumption such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to animals who are raised for consumption, and sometimes used to refer solely to farmed ruminants, such as cattle, sheep, goats and pigs. Horses are considered livestock in the United States. The USDA classifies pork, veal, beef, and lamb (mutton) as livestock, and all livestock as red meat. Poultry and fish are not included in the category. The breeding, maintenance, slaughter and general subjugation of livestock, called '' animal husbandry'', is a part of modern agriculture and has been practiced in many cultures since humanity's transition to farming from hunter-gatherer lifestyles. Animal husbandry practices have varied widely across cultures and time periods. It continues to play a major economic and cultural role in numerous communities. Lives ...

Vector (epidemiology)
In epidemiology, a disease vector is any living agent that carries and transmits an infectious pathogen to another living organism; agents regarded as vectors are organisms, such as parasites or microbes. The first major discovery of a disease vector came from Ronald Ross in 1897, who discovered the malaria pathogen when he dissected a mosquito. Arthropods Arthropods form a major group of pathogen vectors with mosquitoes, flies, sand flies, lice, fleas, ticks, and mites transmitting a huge number of pathogens. Many such vectors are haematophagous, which feed on blood at some or all stages of their lives. When the insects feed on blood, the pathogen enters the blood stream of the host. This can happen in different ways. The ''Anopheles'' mosquito, a vector for malaria, filariasis, and various arthropod-borne-viruses (arboviruses), inserts its delicate mouthpart under the skin and feeds on its host's blood. The parasites the mosquito carries are usually located in its salivary gla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Reservoirs
In infectious disease ecology and epidemiology, a natural reservoir, also known as a disease reservoir or a reservoir of infection, is the population of organisms or the specific environment in which an infectious pathogen naturally lives and reproduces, or upon which the pathogen primarily depends for its survival. A reservoir is usually a living host of a certain species, such as an animal or a plant, inside of which a pathogen survives, often (though not always) without causing disease for the reservoir itself. By some definitions a reservoir may also be an environment external to an organism, such as a volume of contaminated air or water. Because of the enormous variety of infectious microorganisms capable of causing disease, precise definitions for what constitutes a natural reservoir are numerous, various, and often conflicting. The reservoir concept applies only for pathogens capable of infecting more than one host population and only with respect to a defined target popula ...

Confidence Interval
In frequentist statistics, a confidence interval (CI) is a range of estimates for an unknown parameter. A confidence interval is computed at a designated ''confidence level''; the 95% confidence level is most common, but other levels, such as 90% or 99%, are sometimes used. The confidence level represents the long-run proportion of corresponding CIs that contain the true value of the parameter. For example, out of all intervals computed at the 95% level, 95% of them should contain the parameter's true value. Factors affecting the width of the CI include the sample size, the variability in the sample, and the confidence level. All else being the same, a larger sample produces a narrower confidence interval, greater variability in the sample produces a wider confidence interval, and a higher confidence level produces a wider confidence interval. Definition Let be a random sample from a probability distribution with statistical parameter , which is a quantity to be estimate ...

Trafalgar Square
Trafalgar Square ( ) is a public square in the City of Westminster, Central London, laid out in the early 19th century around the area formerly known as Charing Cross. At its centre is a high column bearing a statue of Admiral Nelson commemorating the victory at the Battle of Trafalgar. The battle of 21 October 1805, established the British navy's dominance at sea in the Napoleonic Wars over the fleets of France and Spain. The site around Trafalgar Square had been a significant landmark since the 1200s. For centuries, distances measured from Charing Cross have served as location markers. The site of the present square formerly contained the elaborately designed, enclosed courtyard of the King's Mews. After George IV moved the mews to Buckingham Palace, the area was redeveloped by John Nash, but progress was slow after his death, and the square did not open until 1844. The Nelson's Column at its centre is guarded by four lion statues. A number of commemorative statues and sc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gateway Of India
The Gateway of India is an arch-monument built in the early 20th century in the city of Mumbai (Bombay), India. It was erected to commemorate the landing of King-Emperor George V, the first British monarch to visit India, in December 1911 at Strand Road near Wellington Fountain. The foundation stone was laid in March 1913 for a monument built in the Indo-Islamic style, inspiring by elements of 16th-century Gujarati architecture. The final design of the monument by architect George Wittet was sanctioned only in 1914, and construction was completed in 1924. The structure is a memorial arch made of basalt, which is high, with an architectural resemblance to a triumphial arch as well as Gujarati architecture of the time. After its construction the Gateway was used as a symbolic ceremonial entrance to India for important colonial personnel. The Gateway is also the monument from where the last British troops left India in 1948, following Indian independence. It is located o ...

Piazza San Marco
Piazza San Marco (; vec, Piasa San Marco), often known in English as St Mark's Square, is the principal public square of Venice, Italy, where it is generally known just as ''la Piazza'' ("the Square"). All other urban spaces in the city (except the Piazzetta and the Piazzale Roma) are called ''campi'' ("fields"). The Piazzetta ("little Piazza/Square") is an extension of the Piazza towards San Marco basin in its southeast corner (see plan). The two spaces together form the social, religious and political centre of Venice and are commonly considered together. This article relates to both of them. A remark usually attributed (though without proof) to Napoleon calls the Piazza San Marco "the drawing room of Europe". Description The square is dominated at its eastern end by St Mark's Basilica. It is described here by a perambulation starting from the west front of the church (facing the length of the piazza) and proceeding to the right. The church is described in the article ...
