Oak vs Strasbourg

Informations

An oak is a tree or shrub in the genus Quercus (; Latin "oak tree") of the beech family, Fagaceae. There are approximately 500 extant species of oaks. The common name "oak" also appears in the names of species in related genera, notably Lithocarpus (stone oaks), as well as in those of unrelated species such as Grevillea robusta (silky oaks) and the Casuarinaceae (she-oaks). The genus Quercus is native to the Northern Hemisphere, and includes deciduous and evergreen species extending from cool temperate to tropical latitudes in the Americas, Asia, Europe, and North Africa. North America contains the largest number of oak species, with approximately 90 occurring in the United States, while Mexico has 160 species of which 109 are endemic. The second greatest center of oak diversity is China, which contains approximately 100 species.

Oaks have spirally arranged leaves, with lobate margins in many species; some have serrated leaves or entire leaves with smooth margins. Many deciduous species are marcescent, not dropping dead leaves until spring. In spring, a single oak tree produces both male flowers (in the form of catkins) and small female flowers, meaning that the trees are monoecious. The fruit is a nut called an acorn or oak nut borne in a cup-like structure known as a cupule; each acorn contains one seed (rarely two or three) and takes 6–18 months to mature, depending on their species. The acorns and leaves contain tannic acid, which helps to guard from fungi and insects. The live oaks are distinguished for being evergreen, but are not actually a distinct group and instead are dispersed across the genus.

Strasbourg (UK: , US: , French: [stʁazbuʁ, stʁasbuʁ] (listen); Bas Rhin Alsatian: Strossburi [ˈʃd̥ʁɔːsb̥uʁi] (listen), Haut Rhin Alsatian: Strossburig [ˈʃd̥ʁɔːsb̥uʁiɡ̊] (listen); German: Straßburg [ˈʃtʁaːsbʊʁk] (listen) Latin: Argentoratum) is the capital and largest city of the Grand Est region of France and is the official seat of the European Parliament. Located at the border with Germany in the historic region of Alsace, it is the capital of the Bas-Rhin department. In 2017, the city proper had 280,966 inhabitants and both the Eurométropole de Strasbourg (Greater Strasbourg) and the Arrondissement of Strasbourg had 494,089 inhabitants. Strasbourg's metropolitan area had a population of 790,087 in 2017 (not counting the section across the border in Germany), making it the ninth-largest metro area in France and home to 13% of the Grand Est region's inhabitants. The transnational Eurodistrict Strasbourg-Ortenau had a population of 958,421 inhabitants.Strasbourg is one of the de facto four main capitals of the European Union (alongside Brussels, Luxembourg and Frankfurt), as it is the seat of several European institutions, such as the European Parliament, the Eurocorps and the European Ombudsman of the European Union. An organization separate from the European Union, the Council of Europe (with its European Court of Human Rights, its European Directorate for the Quality of Medicines most commonly known in French as "Pharmacopée Européenne", and its European Audiovisual Observatory) is also located in the city.

Together with Basel (Bank for International Settlements), Geneva (United Nations headquarters in Europe), The Hague (International Court of Justice) and New York City (United Nations world headquarters), Strasbourg is among the few cities in the world that is not a state capital that hosts international organisations of the first order. The city is the seat of many non-European international institutions such as the Central Commission for Navigation on the Rhine and the International Institute of Human Rights. It is the second city in France in terms of international congress and symposia, after Paris. Strasbourg's historic city centre, the Grande Île (Grand Island), was classified a World Heritage Site by UNESCO in 1988, the first time such an honour was placed on an entire city centre. Strasbourg is immersed in Franco-German culture and although violently disputed throughout history, has been a cultural bridge between France and Germany for centuries, especially through the University of Strasbourg, currently the second-largest in France, and the coexistence of Catholic and Protestant culture. It is also home to the largest Islamic place of worship in France, the Strasbourg Grand Mosque.Economically, Strasbourg is an important centre of manufacturing and engineering, as well as a hub of road, rail, and river transportation. The port of Strasbourg is the second-largest on the Rhine after Duisburg in Germany, and the second-largest river port in France after Paris.
