Whole‐genome duplication (polyploidy) occurs frequently and repeatedly within species,
often forming new lineages that contribute to biodiversity, particularly in plants …

Deciphering the global distribution of polyploid plants is fundamental for understanding
plant evolution and ecology. Many factors have been hypothesized to affect the uneven …

Polyploid speciation entails substantial and rapid postzygotic reproductive isolation of
nascent species that are initially sympatric with one or both parents. Despite strong …

Aim Emerging polyploids may depend on environmental niche shifts for successful
establishment. Using the alpine plant Ranunculus kuepferi as a model system, we explore …

Premise of the Study Successful establishment of neopolyploids, and therefore polyploid
speciation, is thought to be contingent on environmental niche shifts from their progenitors …

Highlights•Rapid population growth and dispersal foster polyploid species establishment.•
Introgressive hybridization enhances the persistence of polyploid species.•Multiple …

Habitat divergence plays a driving role in speciation. Severe environmental fluactuations
and/or stress may bring about unreduced gamete formation in germline or mitotic errors in …

Investigators have long searched for a polyploidy paradigm—rules or principles that might
be common following polyploidization (whole‐genome duplication, WGD). Here we attempt …

Polyploidy is important in the evolutionary history of plants, and it has played a crucial role in
shaping the genome structures of all eukaryotes. New and rapidly improving techniques in …

Abstract Background and Aims Niche divergence between polyploids and their lower ploidy
progenitors is one of the primary mechanisms fostering polyploid establishment and …
