Biogeographic history of green alder ( Alnus alnobetula (Ehrh.) K. Koch s.l.) in Eurasia and North America: evidence from genetic and morphological analyses
The green alder ( Alnus alnobetula s.l.) is a cold-resistant boreal-arctic shrub species with a complex intraspecific taxonomy and a wide distribution range covering northern Eurasia and North America. In this study, we assess the level and distribution of diversity in five subspecies ( A. alnobetul...

The green alder ( Alnus alnobetula s.l.) is a cold-resistant boreal-arctic shrub species with a complex intraspecific taxonomy and a wide distribution range covering northern Eurasia and North America.
