In the past two decades our understanding of plant biogeography has been improved
substantially by the introduction of various molecular marker systems. Especially within the …

The impact of unknowingly including a hybrid or an allopolyploid in which rDNA
homogenization (via gene loss, concerted evolution, or some other mechanism) has not …

Early in the development of plant evolutionary biology, genetic drift, fluctuations in
population size, and isolation were identified as critical processes that affect the course of …

TAXON 54 (3) August 2005: 593-604 Vriesendorp & Bakker Reconstructing reticulate
evolution particular taxa (Ellstrand & al, 1996). When hybrid species are included in …

Hybridization is an important cause of abrupt speciation. Hybrid speciation without a change
in ploidy (homoploid hybrid speciation) is well‐established in plants but has also been …

Reliable methods for clone identification are desired to characterise and distinguish
breeding products within the genus Populus L.(Salicaceae). Ten nuclear microsatellite loci …

Genomic studies of speciation often report the presence of highly differentiated genomic
regions interspersed within a milieu of weakly diverged loci. The formation of these …

Plants have unique biological attributes of great interest to researchers investigating
population dynamics. Yet, until recently, organelle DNA had been seldom utilized for …

Environmental gradients are very common and many plant species respond to them through
adaptive genetic change. This can be a first step along a continuum of change that leads …

In this chapter we adopt the broader term ecological speciation, as we review the forms it
may take in flowering plants, or angiosperms, and explore whether there is evidence for …
