Evolutionary processes fuelling rapid species diversification are not yet fully understood,
although their major contribution to overall patterns of plant biodiversity is well established …

Background The genomes of higher plants are, on the majority, polyploid, and hybridisation
is more frequent in plants than in animals. Both polyploidisation and hybridisation contribute …

Traditionally, the Arctic has been viewed as an 'evolutionary freezer'with low evolutionary
rates caused by extreme environmental constraints and depauperated by repeated …

The geology and climate of the western Mediterranean area were strongly modified during
the Late Tertiary and the Quaternary. These geological and climatic events are thought to …

We examined the evolutionary history of the diploid representatives of the genus
Leucanthemum Mill.(Compositae, Anthemideae), which constitutes an extensive polyploid …

As human society has become more mobile, the transfer of species beyond their native
ranges has similarly increased. Human-induced biological invasions now occur around the …

White water–lilies (Nymphaea) provide an excellent model for studying evolutionary
diversification in a discontinuous habitat system, which has experienced dramatic …

• Premise of study: A difference in chromosome numbers (ploidy variation) between species
is usually considered a major barrier to gene flow. Therefore, it is surprising that little is …

Rare plant species are often restricted to small and/or isolated populations that can have
reduced reproductive output and adaptive potential, resulting in an increased probability of …

Most perennial herbaceous plants are able to reproduce vegetatively as well as sexually.
Sometimes, such plants may lose the capacity for sexual reproduction. We have studied the …
