Yu Ito

Yu Ito is an aquatic botanist who has been working in several universities and/or institutes, such as the University of Tokyo (PhD: 2006-2010), University of West Hungary (PostDoc: 2010-2011), University of Saskatchewan (PostDoc: 2011-2012), Aarhus University (PostDoc: 2012), University of Canterbury (PostDoc: 2013-2014), and Xishuangbanna Tropical Botanical Garden (2015-). His area of expertise is taxonomy and systematics.

Dr. Ito is an expert on the family Ruppiaceae, and in 2010 published a worldwide molecular phylogeny of the family,^[1] proposing a new taxonomic classification of three species and one species complex. The Ruppia maritima complex defined there was updated to include in total eight entities.^[2] The systematics of the genus was further changed by the discovery of a new and the most basal species from Western Cape, South Africa (Ruppia bicarpa Yu Ito et Muasya, sp. nov.).^[3] Lectotypification of R. cirrhosa and R. spiralis is made and as a result the former one is synonymized under R. maritima: Buccaferra cirrhosa Petagna in Institutiones Botanicae 5: 1826. 1787 ≡ Ruppia cirrhosa (Petagna) Grande in Bull. Orto Bot. Regia Univ. Napoli 5: 58. 1918. – Lectotype (designated here): [illustration in] P. Micheli, Nova Plantarum Genera: pl. 72, tab. 35. 1729. Ruppia spiralis L. ex Dumort. in Fl. Berg. (Dumotier) 164. 1827 – Lectotype (designated here): origin unknown (LINN 176.2 [digital image!]).^[4] The phylogeny of Zannichelliaceae is among his research interests, in which based on molecular and morphological evidence Australasian Lepilaena is merged into Afro-Eurasian Althenia with the following taxonomic treatment: Althenia F.Petit, Ann. Sci. Observ. 1: 451 (1829) = Lepilaena J. Drumm. ex Harv., Hooker's J. Bot. Kew Gard. Misc. 7: 57. (1855), syn. nov.; Althenia marina (E.L. Robertson) Yu Ito, comb. nov., � Lepilaena marina E.L. Robertson, H.B.S. Womersley, Mar. Benth. Fl. South Australia 1: 80 (1984) = Lepilaena patentifolia E.L. Robertson, Fl. S. Australia 4: 1736. (1986), syn. nov.^[5]

Among the other contributions of him to science include botanical surveys of aquatic plants in tropical Asia, such as Myanmar and Thailand.^[6]^[7]^[8]
