Rennison,Julia Schwarzer,E. Watson,Anja M. Westram,Alex Widmer +33 more
TL;DR: Emergent trends and gaps in understanding are identified, new approaches to more fully integrate genomics into speciation research are proposed, and an integrative definition of the field of speciation genomics is provided.
Journal ArticleDOI
Orchid diversity: an evolutionary consequence of deception?
Salvatore Cozzolino,Alex Widmer +1 more
TL;DR: It is argued that pollination by deceit is one of the keys to orchid floral and species diversity and a better understanding of its evolutionary consequences could help evolutionary biologists to unravel the reasons for the evolutionary success of orchids.
Journal ArticleDOI
The genetic architecture necessary for transgressive segregation is common in both natural and domesticated populations
TL;DR: The results indicate that transgressive segregation provides a general mechanism for the production of extreme phenotypes at both above and below the species level and testify to the possible creative part of hybridization in adaptive evolution and speciation.
Journal ArticleDOI
Evolution of reproductive isolation in plants.
TL;DR: Plant species are typically isolated not by a single factor, but by a large number of different pre- and postzygotic barriers, and their potentially complex interactions, and this phenomenon has often been ignored to date.
Journal ArticleDOI
Glacial refugia: sanctuaries for allelic richness, but not for gene diversity
Alex Widmer,Christian Lexer +1 more
TL;DR: A more complex situation in the European beech Fagus sylvatica is demonstrated, for which some measures of genetic diversity are higher in newly colonized areas than in refugia.
