Polyploidy is a common feature in plants with 35% of angiosperms being polyploid species. Polyploidization has been proposed as one of the most important speciation mechanism in plants, with 15% of all speciation events in flowering plants and 31% in ferns entailing an increase in the number of complete chromosome sets. The frequency of polyploid species formation under natural conditions is often found to be enhanced by environmental changes, such as the large-scale re-structuring of species… 

On the Leucanthemopsis alpina (L.) Heywood growing in the Illyrian region

Results from the investigation suggest that the only population of the species in the Dinaric Alps is found in the Vranica Mts (Bosnia and Herzegovina), and both the ploidy and their genetic distinction indicate that Vranic Mts most probably served as a refugium for the species during the Pleistocene glaciations.

RECONSTRUCTING RETICULATION HISTORY IN A PHYLOGENETIC FRAMEWORK AND THE POTENTIAL OF ALLOPATRIC SPECIATION DRIVEN BY POLYPLOIDY IN AN AGAMIC COMPLEX IN CRATAEGUS (ROSACEAE)

This study demonstrates the use of a variety of phylogenetic approaches to unravel origins and infer reticulation history in a diploid–polyploid complex of black‐fruited Crataegus.

Genetic structure and evolution of Alpine polyploid complexes: Ranunculus kuepferi (Ranunculaceae) as a case study

This study shows the contrasting role played by diploid lineages mostly restricted to persistent refugia and by tetraploids, whose dispersal abilities have permitted their range extension all over the previously glaciated Alpine area and throughout neighbouring mountain massifs.

Plant polyploidy and the evolutionary ecology of plant / animal interactions

Because a large number of plant lineages include polyploid species, the evolution ofPolyploidy may have had major effects on the interaction structure of terrestrial communities.

The frequency of polyploid speciation in vascular plants

It is established that 15% of angiosperm and 31% of fern speciation events are accompanied by ploidy increase, and frequency estimates are higher by a factor of four than earlier estimates and lead to a standing incidence of polyploid species within genera of 35% (n = 1,506).

Phylogeny of a Genomically Diverse Group of Elymus (Poaceae) Allopolyploids Reveals Multiple Levels of Reticulation

The work illustrates the interpretation of complicated phylogenetic results through the sequential consideration of numerous possible explanations, and the results highlight the value of careful inspection of multiple independent molecular phylogenetic estimates, with particular focus on the differences among them.

Polyploid incidence and evolution.

New estimates for the incidence of polyploidy in ferns and flowering plants are presented based on a simple model describing transitions between odd and even base chromosome numbers, and it is indicated that ploidy changes may represent from 2 to 4% of speciation events in flowering plants and 7% in f Ferns.

At the seed and seedling stages, neither niche differentiation nor tetraploid competitive superiority appears sufficient to explain neotetraploids success in the presence of their diploid progenitors.

Diploid and tetraploid snow buttercups have nonoverlapping regional distributions and Habitat differentiation between cytotypes or reproductive exclusion of minority cytotypes may explain the observed segregation at both microgeographic and regional scales.

Phylogenetic patterns and polyploid evolution within the Mediterranean genus Centaurium (Gentianaceae - Chironieae)

Phylogenetic relationships, inferred from sequences of both nrDNA and cpDNA regions, confirm the monophyly of Centaurium and reveal the importance of polyploidy within the genus.
