Anders Sandøe Ørsted, also written as ''Anders Sandoe Oersted'' or ''Anders Sandö Örsted'' (21 June 1816 – 3 September 1872) was a Danish botanist, mycologist, zoologist and marine biologist. He was the nephew of physicist H.C. Ørsted and of politician Anders Sandøe Ørsted.〔Spärck, R. (1932) Anders Sandöe Örsted, pp. 128-130 in: Meisen, V. Prominent Danish Scientists through the Ages. University Library of Copenhagen 450th Anniversary. Levin & Munksgaard, Copenhagen.〕 In his early career, he published on Danish and arctic nematodes〔Ørsted, A.S. (1843) Grønlands Annulata dorsibranchiata. Kongelige Danske Videnskabernes Selskab, Naturhistorisk- mathematiske Afhandliger 10: 153-216.〕〔Ørsted, A.S. (1843) Annulatorum Danicorum Conspectus. I.

(1844) De regionibus marinis: Elementa Topographiae Historiconaturalis Freti Oeresund. Respondente ornatissimo E. Petit; publice defendere studebit A.S. Ørsted. J.C. Scharling, Copenhagen.〕 Between 1845 and 1848, he travelled extensively in Central America and the Caribbean and published numerous papers on the flora, concentrating on the plant families Acanthaceae and Fagaceae.〔Ørsted, A.S.

(1863) (L'Amérique Centrale: Recherches sur sa flora et sa géographie physique ). Copenhague, Bianco Luno〕 He was appointed professor of botany at the University of Copenhagen in 1851, a post he held until 1862. He was succeeded by Ferdinand Didrichsen. His studies of what has since been known as juniper-pear rust showed that this fungus annually switches between two hosts, ''Juniperus sabina'' is the primary (telial) host and pear ''Pyrus communis'' is the secondary (aecial) host. He thus was the first to discover that some plant-parasitic fungi are heteroecious.〔Ørsted, A.S. (1963) Om Sygdomme hos Planterne, som foraarsages af Snyltesvampe, navnlig om Rust og Brand og om Midlerne til deres Forebyggelse. Kjøbenhavn.〕 These studies were continued on other ''Gymnosporangium'' species〔Ørsted, A.S. (1866) Indpodningsforsøg, hvorved det bevises, at der finder et Generationsskifte Sted mellem den paa Enens Grene snyltende Bævrerust (''Podisoma juniperinum'') og den par Rønnens Blade voxende Hornrust (''Roestelia cornuta''). Resumé: Nouvelles observations sur un champignon parasite etc. Bulletin de l'Académie Royale des Sciences et des Lettres de Danemark 1866.〕 The orchid genus ''Oerstedella'' Reichenbach f. is named for him. He is the author of several hundred plant names still in use.〔(IPNI list of plant names with Oerst. as author. )〕 ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Anders Sandøe Ørsted (botanist)」の詳細全文を読む スポンサード リンク
