Species integrity and ploidy stability despite extensive gene flow via introgressive hybridization: the case of Betula species in Iceland
Abstract Background Introgressive hybridization is common in natural birch woodlands in Iceland, where two birch (Betula) species (diploid dwarf birch B. nana and tetraploid tree birch B. pubescens) coexist and hybridize readily. Our previous morphological, cytogenetic and palynological studies show...
