The long-standing hypothesis, that widely disjunct geographic ranges of various extant liverwort groups have been largely resulted from vicariance events from fragmentation of widespread ancestors through tectonic plate movements, has been challenged by the recent studies based on molecular data. In this thesis, two groups of the leafy liverworts in the order Jungermanniales were investigated in order to better... VO - IS - SP - OP - KW - Plant Science N1 - PP - ER -
