Abstract The Balkan Peninsula is widely acknowledged as one of the centers of European
biodiversity and a major glacial refugium for plant species. Its extensive geographic …

Species with wide ranges often exhibit morphological variability that is mostly shaped by
ecological and evolutionary processes, and the resulting diversity is frequently reflected in …

Aim Species responses to global warming will depend on intraspecific diversity, yet studies
of factors governing biogeographic patterns of variability are scarce. Here, we investigate …

Groups of recent speciation are characterized by high levels of introgression and gene flow,
which often confounds delimitation of species on a DNA basis. We analyzed nuclear DNA …

Abstract Heteroploid Knautia sect. Trichera constitutes a taxonomically intricate assemblage
of taxa with highly complex genetic architecture, which is mirrored in high morphological …

Deciduous forests form the dominant natural vegetation of Europe today, but were restricted
to small refugia during Pleistocene cold stages, implying an evolutionary past shaped by …

Abstract Although the Balkan Peninsula belongs to the most mountainous regions of
Europe, phylogeographic structure of its alpine flora remains insufficiently understood …

Species groups spanning large areas of southeastern Europe gained little attention in
phylogenetic studies. We here inferred relationships within the Euphorbia epithymoides …

Abstract The Balkan Peninsula is a hotspot of European biodiversity, harbouring many
endemic species. Cerastium decalvans is a heteroploid species endemic to mountainous …

Picea koraiensis is major silvicultural and timber species in northeast China, and its
distribution area is an important transition zone for genus spruce migration. The degree of …
