Population structure parameters commonly used for diploid species are reexamined for the
particular case of tetrasomic inheritance (autotetraploid species). Recurrence equations that …

Hybridization and polyploidy have been considered as significant evolutionary forces in
adaptation and speciation, especially among plants. Interspecific gene flow generates novel …

Many regional floras contain a high proportion of recently introduced plant species.
Occasionally, hybridization between an introduced species and another species (introduced …

Hybrid speciation has played a significant role in the evolution of angiosperms at the
polyploid level. However, relatively little is known about the importance of hybrid speciation …

• Premise of the study: Long‐distance dispersal can affect speciation processes in two
opposing ways. Dispersal can promote geographic isolation or it can bring together …

Chloroplast DNA sequences were obtained from 331 Asplenium ceterach plants
representing 143 populations from throughout the range of the complex in Europe, plus …

Extensive sharing of chloroplast haplotypes among the silver birch, Betula pendula Roth.,
the downy birch, B. pubescens Ehrh., and the dwarf birch, B. nana L., was discovered using …

The present review summarizes results from the past decade on the systematics, population
genetics, and evolutionary biology of the mustard family, Brassicaceae (Cruciferae). The …

On both recent and ancient time scales, polyploidy (genome doubling) has been a
significant evolutionary force in plants. Here, we examined multiple individuals from …

Of the many processes that generate gene duplications, polyploidy is unique in that entire
genomes are duplicated. This process has been important in the evolution of many …
