“…Hybrid origins for Mibora minima (2 n =14) and Echinaria capitata are not likely explanations for conflicting gene trees in these species because both are diploid (Ortiz et al 1999, Rice et al 2015). There is, however, considerable polyploidy in the more diverse Sesleria , some of which has been attributed to autopolyploidy (Kuzmanović et al 2013). …”

Circumscriptions of and relationships among many genera and suprageneric taxa of the diverse grass tribe Poeae remain controversial. In an attempt to clarify these, we conducted phylogenetic analyses of >2400 new DNA sequences from two nuclear ribosomal regions (ITS, including internal transcribed spacers 1 and 2 and the 5.8S gene, and the 3’-end of the external transcribed spacer (ETS)) and five plastid regions (matK, trnL–trnF, atpF–atpH, psbK–psbI, psbA–rps19–trnH), and of more than 1000 new and previously published ITS sequences, focused particularly on Poeae chloroplast group 1 and including broad and increased species sampling compared to previous studies. Deep branches in the combined plastid and combined ITS+ETS trees are generally well resolved, the trees are congruent in most aspects, branch support across the trees is stronger than in trees based on only ITS and fewer plastid regions, and there is evidence of conflict between data partitions in some taxa. In plastid trees, a strongly supported clade corresponds to Poeae chloroplast group 1 and includes Agrostidinae p.p., Anthoxanthinae, Aveninae s.str., Brizinae, Koeleriinae (sometimes included in Aveninae s.l.), Phalaridinae and Torreyochloinae. In the ITS+ETS tree, a supported clade includes these same tribes as well as Sesleriinae and Scolochloinae. Aveninae s.str. and Sesleriinae are sister taxa and form a clade with Koeleriinae in the ITS+ETS tree whereas Aveninae s.str. and Koeleriinae form a clade and Sesleriinae is part of Poeae chloroplast group 2 in the plastid tree. All species of Trisetum are part of Koeleriinae, but the genus is polyphyletic. Koeleriinae is divided into two major subclades: one comprises Avellinia, Gaudinia, Koeleria, Rostraria, Trisetaria and Trisetum subg. Trisetum, and the other Calamagrostis/Deyeuxia p.p. (multiple species from Mexico to South America), Peyritschia, Leptophyllochloa, Sphenopholis, Trisetopsis and Trisetum subg. Deschampsioidea. Graphephorum, Trisetum cernuum, T. irazuense and T. macbridei fall in different clades of Koeleriinae in plastid vs. nuclear ribosomal trees, and are likely of hybrid origin. ITS and matK trees identify a third lineage of Koeleriinae corresponding to Trisetum subsect. Sibirica, and affinities of Lagurus ovatus with respect to Aveninae s.str. and Koeleriinae are incongruent in nuclear ribosomal and plastid trees, supporting recognition of Lagurus in its own subtribe. A large clade comprises taxa of Agrostidinae, Brizinae and Calothecinae, but neither Agrostidinae nor Calothecinae are monophyletic as currently circumscribed and affinities of Brizinae differ in plastid and nuclear ribosomal trees. Within this clade, one newly identified lineage comprises Calamagrostis coarctata, Dichelachne, Echinopogon (Agrostidinae p.p.) and Relchela (Calothecinae p.p.), and another comprises Chascolytrum (Calothecinae p.p.) and Deyeuxia effusa (Agrostidinae p.p.). Within Agrostidinae p.p., the type species of Deyeuxia and Calamagrostis s.str. are closely related, supporting classification of Dey...

“…In the two plant species, South‐Eastern Carpathian populations showed a closer affinity to the Balkan populations than to the Western Carpathians (which in turn were more closely‐related to the Alps and other northerly parts of the range; see also above). Other studies also confirm the historical links between the two areas and confirm the importance of complex episodes of isolation and expansion (Kuzmanović et al ., ). Finally, in some cases, populations in the Carpathians and the Balkan Peninsula formed allopatric groups that underwent long‐term isolation and eventual speciation (Ronikier & Zalewska‐Gałosz, ).…”

The Carpathians are the largest mountain range in Central Europe. Their geographical position, extent, isolation, landscape heterogeneity, well‐preserved environment, and relatively low impact of Quaternary glaciations make them of utmost importance for studies on European biodiversity and biogeography. In this review, introducing a Special Issue of the Biological Journal of the Linnean Society, we provide an overview of current research and focus on three main aspects: (1) distribution patterns and species richness including endemism; (2) phylogeographical patterns, inference of major barriers, and divergence areas; and (3) cytological studies and cytogeography inferred from vascular plant polyploid complexes. Our survey shows that, although accurate estimation is not possible for several important taxonomic entities because of unavailable or dispersed data, the Carpathians are a clear hotspot of European diversity for many groups of organisms, such as mammals, breeding birds, amphibians, lichens, and vascular plants. Certain groups, not necessarily those with high species richness, are rich in endemic taxa. This holds mainly for subterranean invertebrates, molluscs, grasshoppers, beetles, spiders, and vascular plants. Distribution patterns of endemic richness vary across taxonomic groups, as well as geographically, reflecting both history and habitat features. In general, the South‐Eastern Carpathians have a significantly higher proportion of endemic taxa than the northerly‐situated Western Carpathians. Molecular clock‐based estimations have provided some insight into the diversification age of the Carpathian biota, including a Tertiary origin for some endemic taxa and lineages, especially those confined to environmentally stable habitats. Distribution patterns, as well as phylogeographical and phylogenetic data, corroborate the persistence of many high‐mountain and forest taxa during the Quaternary climatic oscillations, often in multiple spatially delimited areas isolated by physical barriers. Several studies show that the Carpathian massifs played an important role as refugia for rare lineages and/or as stepping stones in migrations. Phylogeographical analysis reveals clear patterns of biogeographical breaks, as well as links, although clear exceptions also confirm that extant distribution patterns are often shaped more by idiosyncratic processes acting at different geological times. Cytogeographical data also uncover several consistent patterns, which probably reflect a deeper evolutionary history. In conclusion, the available data highlight the unique position of the Carpathians in the evolution and preservation of European biota within the European Alpine System.

Background and Aims The Balkan Peninsula is one of the most important centres of plant diversity in Europe.Here we aim to fill the gap in the current knowledge of the evolutionary processes and factors modelling this astonishing biological richness by applying multiple approaches to the Cyanus napulifer group.Methods To reconstruct the mode of diversification within the C. napulifer group and to uncover its relationships with potential relatives with x ¼ 10 from Europe and Northern Africa, we examined variation in genetic markers (amplified fragment length polymorphisms [AFLPs]; 460 individuals), relative DNA content (4 0 ,6-diamidino-2-phenylindole [DAPI] flow cytometry, 330 individuals) and morphology (multivariate morphometrics, 40 morphological characters, 710 individuals). To elucidate its evolutionary history, we analysed chloroplast DNA (cpDNA) sequences of the genus Cyanus deposited in the GenBank database.Key Results The AFLPs revealed a suite of closely related entities with variable levels of differentiation. The C. napulifer group formed a genetically well-defined unit. Samples outside the group formed strongly diversified and mostly species-specific genetic lineages with no further geographical patterns, often characterized also by a different DNA content. AFLP analysis of the C. napulifer group revealed extensive radiation and split it into nine allopatric (sub)lineages with varying degrees of congruence among genetic, DNA-content and morphological patterns. Genetic admixture was usually detected in contact zones between genetic lineages. Plastid data indicated extensive maintenance of ancestral variation across Cyanus perennials.Conclusion The C. napulifer group is an example of a rapidly and recently diversified plant group whose genetic lineages have evolved in spatio-temporal isolation on the topographically complex Balkan Peninsula. Adaptive radiation, accompanied in some cases by long-term isolation and hybridization, has contributed to the formation of this species complex and its mosaic pattern.
