Reproductive isolation in plants occurs through multiple barriers that restrict gene flow
between populations, but their origins remain uncertain. Work in the past decade has shown …

Autopolyploidy is more common in plants than traditionally assumed, but has received little
attention compared with allopolyploidy. Hence, the advantages and disadvantages of …

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 has long been considered a major force in plant evolution. G. Ledyard Stebbins,
Jr., an architect of the Modern Synthesis, elegantly addressed a broad range of topics, from …

Abstract Since Darwin published the “Origin,” great progress has been made in our
understanding of speciation mechanisms. The early investigations by Mayr and Dobzhansky …

In plant conservation, restoration (the augmentation or reestablishment of an extinct
population or community) is a valuable tool to mitigate the loss of habitat. However …

Polyploidy is a mutation with profound phenotypic consequences and thus hypothesized to
have transformative effects in plant ecology. This is most often considered in the context of …

Despite the importance of polyploidy and the increasing availability of new genomic data,
there remain important gaps in our knowledge of polyploid population genetics. These gaps …

Mixed-ploidy species harbor a unique form of genomic and phenotypic variation that
influences ecological interactions, facilitates genetic divergence, and offers insights into the …

Speciation is characterized by the evolution of reproductive isolation between two groups of
organisms. Understanding the process of speciation requires the quantification of barriers to …
