Anti-Locust Research Centre
The Anti-Locust Research Centre (ALRC) was set up in London, United Kingdom, by the Colonial Office in 1945, with the aim of improving the worldwide forecasting and control of locusts. The Russian-British entomologist Boris Uvarov was appointed as its first director. Prior to that, Uvarov had been in charge of a small locust research unit in London, formed in the 1920s within the Imperial Bureau of Entomology. The unit later became known as the Centre for Overseas Pest Research. During World War II, the ALRC concentrated on its forecasting and advisory services with regard to anti-locust campaigns in the Middle East and Africa. After the war it became a dedicated research centre on locusts, making important contributions in the areas of taxonomy, population biology and locust control. Its primary aims at this time were the coordination of international research into the biology of locusts and the organisation of international cooperation in the control of locusts. In 1964, both the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colonial Office
The Colonial Office was a government department of the Kingdom of Great Britain and later of the United Kingdom, first created to deal with the colonial affairs of British North America but required also to oversee the increasing number of colonies of the British Empire. Despite its name, the Colonial Office was never responsible for all Britain's Imperial territories; for example, protectorates fell under the purview of the Foreign Office, and British India was ruled by the East India Company until 1858 (the British Raj ruled the India Office as a result of the Indian Mutiny), while the role of the Colonial Office in the affairs of the Dominions changed as time passed. It was headed by the Secretary of State for the Colonies, also known more informally as the Colonial Secretary. First Colonial Office (1768–1782) Prior to 1768, responsibility for the affairs of the British colonies was part of the duties of the Secretary of State for the Southern Department and a committee ...

Locust
Locusts (derived from the Vulgar Latin ''locusta'', meaning grasshopper) are various species of short-horned grasshoppers in the family Acrididae that have a swarming phase. These insects are usually solitary, but under certain circumstances they become more abundant and change their behaviour and habits, becoming gregarious. No taxonomic distinction is made between locust and grasshopper species; the basis for the definition is whether a species forms swarms under intermittently suitable conditions; this has evolved independently in multiple lineages, comprising at least 18 genera in 5 different acridid subfamilies. Normally, these grasshoppers are innocuous, their numbers are low, and they do not pose a major economic threat to agriculture. However, under suitable conditions of drought followed by rapid vegetation growth, serotonin in their brains triggers dramatic changes: they start to breed abundantly, becoming gregarious and nomadic (loosely described as migrator ...

Boris Uvarov
Sir Boris Petrovitch Uvarov (3 November 1886 – 18 March 1970) was a Russian-British entomologist best known for his work on the biology and ecology of locusts. He has been called the father of acridology. Biography Boris Petrovitch Uvarov was born in Ural'sk, in the Russian Empire (now Oral, Kazakhstan), the youngest of three sons of Pyotr P. Uvarov, a state bank employee, and his wife, Aleksandra. His interest in natural history was aided in young life by his father's gift of six volumes of Brehm's ''Tierleben''. He went to a school in Uralsk from 1895 to 1902 where he was encouraged by S. M. Zhuravlev. He then studied briefly at the School of Mining at Ekaterinoslav (now Dnepropetrovsk) but transferred in 1906 to study biology in the Saint Petersburg State University, graduating in 1910. He was influenced by the teachings of Shimkevitch, Wagner, and Palladin but enjoyed most the meetings of the Russian Entomological Society where he was influenced by, among others, D. N. Bo ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the ...

Population Biology
The term population biology has been used with different meanings. In 1971 Edward O. Wilson ''et al''. used the term in the sense of applying mathematical models to population genetics, community ecology, and population dynamics. Alan Hastings used the term in 1997 as the title of his book on the mathematics used in population dynamics. The name was also used for a course given at UC Davis in the late 2010s, which describes it as an interdisciplinary field combining the areas of ecology and evolutionary biology. The course includes mathematics, statistics, ecology, genetics, and systematics Biological systematics is the study of the diversification of living forms, both past and present, and the relationships among living things through time. Relationships are visualized as evolutionary trees (synonyms: cladograms, phylogenetic t .... Numerous types of organisms are studied. The journal '' Theoretical Population Biology'' is published.

Department For International Development
The Department for International Development (DFID) was a department of HM Government responsible for administering foreign aid from 1997 to 2020. The goal of the department was "to promote sustainable development and eliminate world poverty". DFID was headed by the United Kingdom's Secretary of State for International Development. The position was last held between 13 February 2020 and the department's abolishment on 2 September 2020 by Anne-Marie Trevelyan. In a 2010 report by the Development Assistance Committee (DAC), DFID was described as "an international development leader in times of global crisis". The UK aid logo is often used to publicly acknowledge DFID's development programmes are funded by UK taxpayers. DFID's main programme areas of work were Education, Health, Social Services, Water Supply and Sanitation, Government and Civil Society, Economic Sector (including Infrastructure, Production Sectors and Developing Planning), Environment Protection, Research, and Hu ...

Chatham, Kent
Chatham ( ) is a town located within the Medway unitary authority in the ceremonial county of Kent, England. The town forms a conurbation with neighbouring towns Gillingham, Rochester, Strood and Rainham. The town developed around Chatham Dockyard and several Army barracks, together with 19th-century forts which provided a defensive shield for the dockyard. The Corps of Royal Engineers is still based in Chatham at Brompton Barracks. The Dockyard closed in 1984, but the remaining major naval buildings are an attraction for a flourishing tourist industry. Following closure, part of the site was developed as a commercial port, other parts were redeveloped for business and residential use, and part was used as the Chatham Historic Dockyard museum. Its attractions include the submarine . The town has important road links and the railway and bus stations are the main interchanges for the area. It is the administrative headquarters of Medway unitary authority, as well as its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
