Geographical Distribution Pattern of Macromitrium in the World and Its Biogeographical Significance

doi:10.7525/j.issn.1673-5102.2017.02.002

Abstract

Abstract: The genus Macromitrium(Orthotrichaceae, Bryophyta) is an important taxon in bryological systematics, ecology and biological conservation. On the basis of our taxonomical revision of the genus, we got the distribution data of 274 species of the genus in 14 geographical unites(suggested by "Index Muscorum") in the world.By using Clustering Analysis and Detrended Correspondence Analysis(DCA), we got a dendrogram and a three-dimensional scatter plots to reveal the distribution pattern of the genus visually. The results showed a distinctive floristic differentiation of Macromitrium among As2, Oc, As3-4, Afr2-3-4, Am2-3-4-5, and Austr1-2, with highest diversity in Tropical Asia and Tropical America. Except M.microstomum(Hook.& Grev.) Schwägr., all other species were recorded from a single or a few geographical unites. Among different global regions, Macromitrium differentiated not only in its floristic elements, but also in their morphological characters. We discussed the systematic and biogeographical significances of the genus according its global distribution pattern.

Key words: Macromitrium, geographical distribution pattern, Clustering Analysis, Detrended Correspondence Analysis(DCA)
