Alleles that introgress between species can influence the evolutionary and ecological fate of
species exposed to novel environments. Hybrid offspring of different species are often unfit …

Hybridization has played an important role in the evolution of many lineages. With the
growing availability of genomic tools and advancements in genomic analyses, it is becoming …

The importance of hybridization in plant speciation and evolution has been debated for
decades, with opposing views of hybridization as either a creative evolutionary force or …

Reduced fitness in interpopulation hybrids can be a first indication of genetic
incompatibilities that may ultimately lead to reproductive isolation and speciation. A growing …

An unintended consequence of global change is an increase in opportunities for
hybridization among previously isolated lineages. Here we illustrate how global change can …

Ecology affects each of the three principal processes leading to speciation: genetic
differentiation among populations within species, acquisition of reproductive isolation …

Sunflowers of the genus Helianthus are models for hybridization research and contain three
of the best-studied examples of homoploid hybrid speciation. To understand a broader …

Hybridization is a potent evolutionary process that can affect the origin, maintenance, and
loss of biodiversity. Because of its ecological and evolutionary consequences, an …

Rates of hybridization are predicted to increase due to climate change and human activity
that cause redistribution of species and bring previously isolated populations into contact. At …

Interspecies relationships in Nicotiana (Solanaceae) are complex because 40 species are
diploid (two sets of chromosomes) and 35 species are allotetraploid (four sets of …
