Hybridization has long been recognized as a fundamental evolutionary process in plants
but, until recently, our understanding of its phylogenetic distribution and biological …

Radiations are especially important for generating species biodiversity in mountainous
ecosystems. The contribution of hybridization to such radiations has rarely been examined …

Whole‐genome duplication has shaped the evolution of angiosperms and other organisms,
and is important for many crops. Structural reorganization of chromosomes and repatterning …

Theoretically, the coexistence of diploids and related polyploids is constrained by
reproductive and competitive mechanisms. Although niche differentiation can explain the …

Premise Hybridization and polyploidization are common in vascular plants and important
drivers of biodiversity by facilitating speciation and ecological diversification. A primary …

Homoploid hybrid speciation is challenging to document because hybridization can lead to
outcomes other than speciation. Thus, some authors have argued that establishment of …

Rapid evolution may play an important role in the range expansion of invasive species and
modify forecasts of invasion, which are the backbone of land management strategies …

Allopolyploidy is a common speciation mechanism in plants; however, its physiological and
ecological consequences in niche partitioning have been scarcely studied. In this sense …

Hybrid zones occur in nature when populations with limited reproductive barriers overlap in
space. Many hybrid zones persist over time, and different models have been proposed to …

Both hybridization and intraspecific morphological variation across environmental gradients
complicate species delineation. We aimed to discern both possibilities that may blur species …
