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, 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. 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.). Lectotypification of R. cirrhosa and R. spiralis are 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!]). 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.
Among the other contributions of him to science include botanical surveys of aquatic plants in tropical Asia, such as Myanmar and Thailand.
