Given the question: Information: - A university ("a whole", "a corporation") is an institution of higher (or tertiary) education and research which grants academic degrees in various subjects. Universities typically provide undergraduate education and postgraduate education. - Richard "Dick" Levins (June 1, 1930 January 19, 2016) was an ex-tropical farmer turned ecologist, a population geneticist, biomathematician, mathematical ecologist, and philosopher of science who had researched diversity in human populations. Until his death, Levins was a university professor at the Harvard T.H. Chan School of Public Health and a long-time political activist. He was best known for his work on evolution and complexity in changing environments and on metapopulations. Levins' writing and speaking is extremely condensed. This, combined with his Marxism, has made his analyses less well-known than those of some other ecologists and evolutionists who were adept at popularization. One story of his Chicago years is that, in order to understand his lectures, his graduate students each needed to attend Levins' courses three times: the first time to acclimate themselves to the speed of his delivery and the difficulty of his mathematics; the second to get the basic ideas down; and the third to pick up his subtleties and profundities. - The Royal Academy of Turku (or "Abo Kungliga Akademi", ) was the first university in Finland, and the only Finnish university that was founded when the country still was a part of Sweden. In 1809, after Finland became a Grand Duchy under the suzerainty of the Russian Tzar, it was renamed the "Imperial Academy of Turku". In 1828, after the Great Fire of Turku, the institution was moved to Helsinki, in line with the relocation of the Grand Duchy's capital. It was finally renamed the University of Helsinki when Finland became a sovereign nation-state in 1917. - A metapopulation consists of a group of spatially separated populations of the same species which interact at some level. The term metapopulation was coined by Richard Levins in 1969 to describe a model of population dynamics of insect pests in agricultural fields, but the idea has been most broadly applied to species in naturally or artificially fragmented habitats. In Levins' own words, it consists of "a population of populations". - Ilkka A. Hanski ForMemRS ( born 14 February 1953 ) is a Finnish scientist , working in the field of ecology , at the University of Helsinki , Finland . The Metapopulation Research Center led by Hanski has been nominated as a Center of Excellence by the Academy of Finland . The group studies species living in fragmented landscapes and attempts to advance such research of metapopulation ecology that can be applied to preserving nature . Metapopulation ecology itself studies populations of plants and animals which are separated in space by occupying patches . Ilkka Hanski took his Bachelor 's degree and Licentiate 's degree in the University of Helsinki in 1976 and Doctoral degree from the University of Oxford in 1979 . He was appointed as a docent in the University of Helsinki in 1981 and in the University of Joensuu in 1983 . Hanski was a graduate student in Oxford from 1976 to 1979 . He has worked in the Academy of Finland from 1978 to 1988 as well as from 1991 to 1992 . He worked as an acting professor of zoology in the University of Helsinki from 1988 to 1991 , and was appointed ( full ) professorship of zoology in 1993 . Hanski has served as an Academy Professor for the Academy of Finland from 1996 ( also currently ) . In 2000 he was awarded the Balzan Prize for Ecological Sciences . In 2000 , he was elected a foreign members of the Royal Swedish Academy of Sciences . In June 2005 , he was the second Finnish scientist ever made an Honorary Fellow of the Royal Society of London . In April 2006 , he was made an Honorary Fellow of the National Academy of Sciences . He was awarded the Crafoord Prize in biosciences 2011 '' for his pioneering studies on how spatial variation affects the dynamics of animal and plant populations '' . Hanski is married with three children and lives in Helsinki , Finland . The central questions of metapopulation biology studies by Hanski have several practical applications . For example , understanding biodiversity and population variability is essential for practical work in... - The Academy of Finland is a governmental funding body for scientific research in Finland. It is based in Helsinki. Yearly, the Academy administers over 260 million euros to Finnish research activities. Over 5,000 researchers are working on the projects supported by the academy. The Academy functions as a funding body only and is not a school. However, personnel funded by the Academy can use the title referring to it, e.g. professors will be called "akatemiaprofessori". Academy professor funding has a term of 5 years. - Saint Petersburg is Russia's second-largest city after Moscow, with fivemillion inhabitants in 2012, and an important Russian port on the Baltic Sea. It is politically incorporated as a federal subject (a federal city). Situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, it was founded by Tsar Peter the Great on May . In 1914, the name was changed from Saint Petersburg to Petrograd, in 1924 to Leningrad, and in 1991 back to Saint Petersburg. Between 17131728 and 17321918, Saint Petersburg was the imperial capital of Russia. In 1918, the central government bodies moved to Moscow. - The University of Helsinki (, , abbreviated UH) is a university located in Helsinki, Finland since 1829, but was founded in the city of Turku (in Swedish "Abo") in 1640 as the "Royal Academy of Turku", at that time part of the Swedish Empire. It is the oldest and largest university in Finland with the widest range of disciplines available. Around 36,500 students are currently enrolled in the degree programs of the university spread across 11 faculties and 11 research institutes. - Russia (from the Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara. - Stockholm (or ) is the capital of Sweden and the most populous city in the Nordic countries; 932,917 people live in the municipality, approximately 1.5 million in the urban area, and 2.3 million in the metropolitan area. The city is spread across 14 islands on the coast in the southeast of Sweden at the mouth of Lake Malaren, by the Stockholm archipelago and the Baltic Sea. The area has been settled since the Stone Age, in the 6th millennium BC, and was founded as a city in 1252 by a Swedish statesman Birger Jarl. It is also the capital of Stockholm County. - The Gulf of Finland is the easternmost arm of the Baltic Sea. It extends between Finland (to the north) and Estonia (to the south) all the way to Saint Petersburg in Russia, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbours are located farthest in, near Saint Petersburg (including Primorsk). As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. - Tallinn (or ) is the capital and largest city of Estonia. It is situated on the northern coast of the country, on the shore of the Gulf of Finland, south of Helsinki, east of Stockholm and west of Saint Petersburg.
