Mating system variation and assortative mating of sympatric bromeliads (Pitcairnia spp.) endemic to neotropical inselbergs

Palma-Silva, Clarisse ; Cozzolino, Salvatore ; Paggi, Gecele Matos ; Lexer, Christian ; Wendt, Tânia

In: American Journal of Botany, 2015, vol. 102, no. 5, p. 758–764

Premise of the study: The mating system is an important component of the complex set of reproductive isolation barriers causing plant speciation. However, empirical evidence showing that the mating system may promote reproductive isolation in co-occurring species is limited. The mechanisms by which the mating system can act as a reproductive isolation barrier are also largely unknown. Methods:...

Components of reproductive isolation between Orchis mascula and Orchis pauciflora

Studies of the strength and nature of reproductive isolation (RI) between species can greatly contribute to our understanding of speciation. Although the role of RI in speciation is well recognized, there is a dearth of information on the contributions of different barriers between related plant species. Here, we estimated multiple components of RI between two Mediterranean orchid sister species...

Phylogeography and genetic differentiation along the distributional range of the orchid Epidendrum fulgens: a Neotropical coastal species not restricted to glacial refugia

Pinheiro, Fábio ; Barros, Fábio De ; Palma-Silva, Clarisse ; Fay, Michael F. ; Lexer, Christian ; Cozzolino, Salvatore

In: Journal of Biogeography, 2011, vol. 38, no. 10, p. 1923–1935

Aim Phylogeographical studies in the Brazilian Atlantic Forest (BAF) have mostly included species associated with forest habitats, whereas taxa associated with grassland and sand-dune plant communities have so far been largely overlooked. This study examines the phylogeography of the orchid Epidendrum fulgens, which occurs on coastal sand dunes and granitic outcrops, in order to identify major...

Sympatric bromeliad species (Pitcairnia spp.) facilitate tests of mechanisms involved in species cohesion and reproductive isolation in Neotropical inselbergs

Palma-Silva, Clarisse ; Wendt, T. ; Pinheiro, Fábio ; Barbará, Thelma ; Fay, Michael F. ; Cozzolino, Salvatore ; Lexer, Christian

In: Molecular Ecology, 2011, vol. 20, no. 15, p. 3185–3201

The roles of intra- and interspecific gene flow in speciation and species evolution are topics of great current interest in molecular ecology and evolutionary biology. Recent modelling studies call for new empirical data to test hypotheses arising from the recent shift from a ‘whole-genome reproductive isolation’ view to a ‘genic’ view of species and speciation. Particularly scarce (and...

Polymorphism of postmating reproductive isolation within plant species

Scopece, Giovanni ; Lexer, Christian ; Widmer, Alex ; Cozzolino, Salvatore

In: Taxon, 2010, vol. 59, no. 5, p. 1367-1374

Speciation can be viewed as the evolution of reproductive isolation between formerly interbreeding populations. Recent years have seen great advances in our understanding of the genetic mechanisms underlying postmating reproductive isolation during plant speciation. Nevertheless, little is known about the early stages of species divergence and the evolution of reproductive isolation at the...

Hybridization and introgression across different ploidy levels in the neotropical orchids Epidendrum fulgens and E. puniceoluteum (Orchidaceae)
