Rosemary Lowe-McConnell
Rosemary Helen Lowe-McConnell (née Rosemary Helen Lowe; 24 June 1921 – 22 December 2014) was an English ichthyologist, ecologist, and limnologist known for research on tilapia and aquaculture. Working in the tropical waters of Africa and South America, Lowe-McConnell was a pioneer in the study of tropical fish ecology and an early adopter of the use of scuba diving for scientific research. Biography Rosemary Helen Lowe was educated at Howell's School in Denbigh, Wales before receiving B.S., M.Sc., and D.Sc. degrees from the University of Liverpool. She went from there to the Freshwater Biological Association, Far Sawrey working on various projects aimed at producing wartime food from fresh waters. Following World War II, in 1945, Lowe-McConnell conducted a survey of tilapia fisheries in the southern part of Lake Nyasa, continuing the previous survey done in 1939 by Ethelwynn Trewavas, Kate Ricardo Bertram, and John Borley. Lowe-McConnell received no support from any fisheri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century. The English language, the Anglican Church, and Eng ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethelwynn Trewavas
Ethelwynn Trewavas (5 November 1900 – 16 August 1993) was an ichthyologist at the British Museum of Natural History. She was known for her work on the families Cichlidae and Sciaenidae.

Botswana
Botswana (, ), officially the Republic of Botswana ( tn, Lefatshe la Botswana, label= Setswana, ), is a landlocked country in Southern Africa. Botswana is topographically flat, with approximately 70 percent of its territory being the Kalahari Desert. It is bordered by South Africa to the south and southeast, Namibia to the west and north, and Zimbabwe to the northeast. It is connected to Zambia across the short Zambezi River border by the Kazungula Bridge. A country of slightly over 2.3 million people, Botswana is one of the most sparsely populated countries in the world. About 11.6 percent of the population lives in the capital and largest city, Gaborone. Formerly one of the world's poorest countries—with a GDP per capita of about US$70 per year in the late 1960s—it has since transformed itself into an upper-middle-income country, with one of the world's fastest-growing economies. Modern-day humans first inhabited the country over 200,000 years ago. The Tswa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bechuanaland Protectorate
The Bechuanaland Protectorate () was a protectorate established on 31 March 1885, by the United Kingdom of Great Britain and Ireland (later the United Kingdom of Great Britain and Northern Ireland) in Southern Africa. It became the Republic of Botswana on 30 September 1966. History Scottish missionary John Mackenzie (1835–1899), a Congregationalist of the London Missionary Society (LMS), who lived at Shoshong from 1862–1876, "believed that the BamaNgwato and other African peoples with whom he worked were threatened by Boer freebooters encroaching on their territory from the south". He campaigned for the establishment of what became the Bechuanaland Protectorate, to be ruled directly from Britain. ''Austral Africa: Losing It or Ruling It'' is Mackenzie's account of events leading to the establishment of the protectorate. Influenced by Mackenzie, in January 1885 the British cabinet decided to send a military expedition to South Africa to assert British sovereig ...

Colonial Service
The Colonial Service, also known as His/Her Majesty's Colonial Service and replaced in 1954 by Her Majesty's Overseas Civil Service (HMOCS), was the British government service that administered most of Britain's overseas possessions, under the authority of the Secretary of State for the Colonies and the Colonial Office in London. It did not operate in British India, where the same function was delivered by the Indian Civil Service, nor in the Anglo-Egyptian Sudan, which was administered by the Sudan Political Service, nor in the internally self-governing colony of Southern Rhodesia. History The British Government's overall responsibility for the management of the territories overseas in the early 19th century lay with successive departments dealing with the various colonies and "plantations", until in 1854 a separate Colonial Office was created headed by a Secretary of State for the Colonies. That office was not responsible for the territories of the Indian Empire, including ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichlid
Cichlids are fish from the family Cichlidae in the order Cichliformes. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of ''Fishes of the World'' as the two families in the Cichliformes, part of the subseries Ovalentaria. This family is both large and diverse. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. New species are discovered annually, and many species remain undescribed. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. Many cichlids, particularly tilapia, are important food fishes, while others, such as the '' Cichla'' species, are valued game fish. The family also includes many popular freshwater ...

Humphry Greenwood
Peter Humphry Greenwood FRS FIBiol (21 April 1927 – 3 March 1995) was an English ichthyologist. Humphry married fellow student Marjorie George (1924 – 2006) in 1950. He was elected a Fellow of the Royal Society in 1985. He was known for his work on the species flocks of cichlids in the African Great Lakes, and for studies of the phylogeny and systematics of teleosts. Tribute The cichlid fish ''Diplotaxodon greenwoodi'' is named for him. Also '' Brachyaetoides greenwoodi'' Bonde, 2008 is named for him.

Crocodile
Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators and caimans (family Alligatoridae), the gharial and false gharial (family Gavialidae) among other extinct taxa. Although they appear similar, crocodiles, alligators and the gharial belong to separate biological families. The gharial, with its narrow snout, is easier to distinguish, while morphological differences are more difficult to spot in crocodiles and alligators. The most obvious external differences are visible in the head, with crocodiles having narrower and longer heads, with a more V-shaped than a U-shaped snout compared to alligators and caimans. Another obvious trait is that the upper and lower jaws of the crocodiles are the same width, and the teeth in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
