Hybridization is an evolutionary phenomenon that has fascinated biologists for centuries.
Prior to the advent of whole-genome sequencing, it was clear that hybridization had played …

The brown algae (Phaeophyceae) are a group of multicellular heterokonts that are
ubiquitous in today's oceans. Large brown algae from multiple orders are the foundation to …

Northern Hemisphere forests changed drastically in the early Eocene with the diversification
of the oak family (Fagaceae). Cooling climates over the next 20 million years fostered the …

Homoploid hybrid speciation in animals has been inferred frequently from patterns of
variation, but few examples have withstood critical scrutiny. Here we report a directly …

I consider how the study of genetic variation has influenced efforts to conserve natural
populations over the last 50 years. Studies with allozymes in the 1970s provided the first …

The species problem has triggered the publication of an almost infinite number of theoretical
and practical studies, including quite a number of books. I should, therefore, perhaps briefly …

Hybridization, defined as breeding between two distinct taxonomic units, can have an
important effect on the evolutionary patterns in cross-breeding taxa. Although interspecific …

It has long been recognized that hybridization and polyploidy are prominent processes in
plant evolution. Although classically recognized as significant in speciation and adaptation …

The study of reproductive isolation and species barriers frequently focuses on mitochondrial
genomes and has produced two alternative and almost diametrically opposed narratives. On …

Hybridization between naturally co-occurring species that normally do not interbreed is
being documented following anthropogenic habitat modifications for an increasing number …
