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 intraspecific taxonomy. Dianthus sylvestris in the Balkan Peninsula encompasses six subspecies (D. sylvestris subspp. alboroseus, bertisceus, kozjakensis, nodosus, sy...

Editorial to the topical collection "Plants of the Balkan Peninsula in Space and Time"

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 heterogeneity and diverse mosaic of habitats, coupled with relatively high environmental stability over long periods, have enabled the diversification of lineages and simultaneously fost...

The mustard family (Brassicaceae) is a scientifically and economically important family, containing the model plant Arabidopsis thaliana and numerous crop species that feed billions worldwide. Despite its relevance, most published family phylogenies are incompletely sampled, generally contain massive polytomies, and/or show incongruent topologies b...

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 morphological or environmental factors, as well as its geographical segregation. We estimated a relative GS (RGS) of 707 individuals from 162 populations of Dianthus sylvest...

The Balkan Peninsula played an important role in the evolution of many Mediterranean plants and served as a major source for post-Pleistocene colonisation of central and northern Europe. Its complex geo-climatic history and environmental heterogeneity significantly influenced spatiotemporal diversification and resulted in intricate phylogeographic...

The nomenclature of 14 taxa from Central and Southern Europe within the Dianthus virgineus group is discussed.

Within the isophyllous group of Campanula ser. Garganicae, represented by species of prevalent Adriatic and Ionian distribution , a rare new endemic species named C. cremnophila is described and illustrated from Pelješac Peninsula and the nearby Elaphite islands of Olipa and Jakljan (southern Croatia). It is a chasmophyte growing on calcareous rock...

Alyssum austrodalmaticum was originally described as an endemic species from southern Croatia. It has been considered a dubious taxon because its holotype specimen got lost and because of the scant information contained in the protologue. To settle the interpretation of the name and its application to other Western Balkan populations, a neotype was...

Until now, the genus Alyssum L. has been represented by a total of 19 taxa in the Flora Croatica Database (FCD). In this paper a detailed review of this genus in Croatian flora was carried out based on most recent phylogenetic, taxonomic, and nomenclatural studies. Based on the presented results five of the current taxa are not subjected to any nom...

The evolution of species or ecotypes can occur gradually through neutral and adaptive genetic changes. To explore the influence of natural selection during early phases of divergence, morphological and ecological discontinuity and its adaptive significance were investigated in six pairs of alpine and independently evolved montane populations of Hel...

Background Polyploidy is one of the most important evolutionary pathways in flowering plants and has significantly contributed to their diversification and radiation. Due to the prevalence of reticulate evolution spanning three ploidy levels, Knautia is considered one of the taxonomically most intricate groups in the European flora. On the basis of...
