Background There are conflicting views between palaeobotanists and plant systematists/
evolutionary biologists regarding the occurrence of plant speciation in the Quaternary …

The use of DNA sequence data in plant systematics has brought us closer than ever to
formulating well-founded hypotheses about phylogenetic relationships, and phylogenetic …

By harbouring ca. 3500 native vascular plant species in an area of ca. 170 000 km 2, the
European Alps represent a region of very high species diversity. Using the most recently …

Water-crowfoots (Ranunculus sect. Batrachium) are one of the taxonomically most intricate
groups of aquatic plants. Investigation of its species is complicated by morphological …

The largest alpine–nival vegetation permanent plot site in the Alps, the GLORIA mastersite
Schrankogel (Tirol, Austria), provided evidence of warming-driven vegetation changes …

Genome size (GS) is an important characteristic that may be helpful in delimitation of taxa,
and multiple studies have shown correlations between intraspecific GS variation and …

The Eurasian steppes occupy a significant portion of the worldwide land surface and their
biota have been affected by specific past range dynamics driven by ice ages-related climatic …

Abstract Background and Aims Ecological differentiation is recognized as an important factor
for polyploid speciation, but little is known regarding whether the ecological niches of …

Speciation among populations connected by gene flow is driven by adaptation to different
environments, but underlying gene–environment associations remain largely unknown …

Leaf shape exhibits tremendous diversity in angiosperms. It has long been argued that leaf
shape can affect major physiological and ecological properties of plants and thus is likely to …
