Despite the importance of polyploidy and the increasing availability of new genomic data,
there remain important gaps in our knowledge of polyploid population genetics. These gaps …

Abstract Background and Aims Differential responses of closely related species to
submergence can provide insight into the evolution and mechanisms of submergence …

• Premise of the study: Hybridization has played an important role in the evolution and
ecological adaptation of diploid and polyploid plants. Artemisia tridentata (Asteraceae) …

Background Effects of polyploidisation on gene flow between natural populations are little
known. Central European diploid and tetraploid populations of Arabidopsis arenosa and A …

Despite their complex evolutionary histories, aquatic plants are highly underrepresented in
contemporary biosystematic studies. Of them, the genus Callitriche is particularly interesting …

Allopolyploidization often happens recurrently, but the evolutionary significance of its
iterative nature is not yet fully understood. Of particular interest are the gene flow dynamics …

Triploids can play an important role in polyploid evolution. However, their frequent sterility is
an obstacle for the origin and establishment of neotetraploids. Here we analyzed the …

Turnera sidoides is a complex of outcrossing, perennial, rhizomatous herbs that is widely
distributed in southern South America. Five subspecies are recognized taxonomically based …

Ecological niche shifts between diploid and tetraploid plants remains a topic with potential
for plant ecology and evolution. Here, we identified populations of Fragaria (Rosaceae) from …
