Large contribution of clonal reproduction to the distribution of deciduous liana species (Wisteria floribunda) in an old-growth cool temperate forest: evidence from genetic analysis

Extensive clonal (vegetative) reproduction in lianas is a common and important life history strategy for regeneration and colonization success. However, few studies have evaluated the contribution of clonal reproduction to stand-level distribution of lianas in their natural habitat using genetic tools. The objectives of the present study were to investigate (1) the contribution of clonal reproduction to the distribution of Wisteria floribunda, (2) the size of clonal patches and (3) how the distribution patterns of W. floribunda clones are affected by micro-topography
