Journal ArticleDOI
Cross-species transfer of nuclear microsatellite markers: potential and limitations.
Thelma Barbará,Clarisse Palma-Silva,Gecele Matos Paggi,Fernanda Bered,Michael F. Fay,Christian Lexer +5 more
TL;DR: The potential for successful cross‐species transfer appears highest in species with long generation times, mixed or outcrossing breeding systems, and where genome size in the target species is small compared to the source.
Journal ArticleDOI
Population differentiation and species cohesion in two closely related plants adapted to neotropical high-altitude 'inselbergs', Alcantarea imperialis and Alcantarea geniculata (Bromeliaceae).
TL;DR: The results indicate a high potential for inselbergs as venues for studies of the molecular ecology and genetics of continental radiations, such as the one that gave rise to the extraordinary diversity of adaptive strategies and phenotypes seen in Bromeliaceae.
Journal ArticleDOI
Sympatric bromeliad species (Pitcairnia spp.) facilitate tests of mechanisms involved in species cohesion and reproductive isolation in Neotropical inselbergs.
Clarisse Palma-Silva,Tânia Wendt,Fábio Pinheiro,Thelma Barbará,Thelma Barbará,Michael F. Fay,Salvatore Cozzolino,Christian Lexer +7 more
TL;DR: The results suggest that incomplete lineage sorting, hybridization and introgression form integral aspects of adaptive radiation in Neotropical inselberg ‘archipelagos’, which should be of special interest to students of speciation in mountain systems, and to ongoing conservation programmes in the Atlantic Rainforest biodiversity hotspot.
Journal ArticleDOI
Range-wide patterns of nuclear and chloroplast DNA diversity in Vriesea gigantea (Bromeliaceae), a neotropical forest species
Clarisse Palma-Silva,Clarisse Palma-Silva,Clarisse Palma-Silva,Christian Lexer,Christian Lexer,Gecele Matos Paggi,Thelma Barbará,Thelma Barbará,Fernanda Bered,Maria Helena Bodanese-Zanettini +9 more
TL;DR: The link between patterns of genetic and species diversity supports the hypothesis that both were shaped by the same biogeographic processes, triggered by the climatic oscillations of the Pleistocene.
Journal ArticleDOI
Genomic Admixture Analysis in European Populus spp. Reveals Unexpected Patterns of Reproductive Isolation and Mating
Christian Lexer,Christian Lexer,Jeffrey A. Joseph,Marcela van Loo,Thelma Barbará,Thelma Barbará,Berthold Heinze,Dénes Bartha,Stefano Castiglione,Michael F. Fay,C. Alex Buerkle +10 more
TL;DR: It is shown that reproductive isolation between these species is much stronger than previously assumed but this cannot prevent the introgression of neutral or advantageous alleles, and unexpected genotypic gaps exist between recombinant hybrids and their parental taxa.
