Cross‐species transfer of nuclear microsatellite markers: potential and limitations
Molecular ecologists increasingly require ‘universal’ genetic markers that can easily be transferred between species. The distribution of cross‐species transferability of nuclear microsatellite loci… Expand

Population differentiation and species cohesion in two closely related plants adapted to neotropical high‐altitude ‘inselbergs’, Alcantarea imperialis and Alcantarea geniculata (Bromeliaceae)
Isolated granitic rock outcrops or ‘inselbergs’ may provide a window into the molecular ecology and genetics of continental radiations under simplified conditions, in analogy to the use of oceanic… Expand

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

Genomic Admixture Analysis in European Populus spp. Reveals Unexpected Patterns of Reproductive Isolation and Mating
Admixture between genetically divergent populations facilitates genomic studies of the mechanisms involved in adaptation, reproductive isolation, and speciation, including mapping of the loci… Expand

Range-wide patterns of nuclear and chloroplast DNA diversity in Vriesea gigantea (Bromeliaceae), a neotropical forest species
The processes that have shaped the extraordinary species diversity in neotropical rainforests are poorly understood, and knowledge about the patterns of genetic diversity across species' ranges is… Expand

A set of polymorphic microsatellite loci for Vriesea gigantea and Alcantarea imperialis (Bromeliaceae) and cross-amplification in other bromeliad species
Fifteen polymorphic microsatellite markers were isolated and characterized in two species of Bromeliaceae: Vriesea gigantea and Alcantarea imperialis . The number of alleles observed for each locus… Expand

Molecular phylogenetics of the Brazilian giant bromeliads (Alcantarea, Bromeliaceae): implications for morphological evolution and biogeography.
The genus Alcantarea comprises near 30 species endemic to rocky outcrops from eastern Brazil. Most species are ornamental and several are threatened due to habitat loss and over collection. In this… Expand

Genetic relationships and variation in reproductive strategies in four closely related bromeliads adapted to neotropical 'inselbergs': Alcantarea glaziouana, A. regina, A. geniculata and A.…
BACKGROUND AND AIMS Bromeliads (Bromeliaceae) adapted to rock outcrops or 'inselbergs' in neotropical rain forests have been identified as suitable plant models for studying population divergence and… Expand

Identifying the generic limits of the Cheilanthoid genus Doryopteris
Morphology-based delimitation of genera in the Cheilanthoid ferns has proved to be problematic and understanding of the phylogeny and relationships amongst Cheilanthoid ferns based on morphological… Expand

Recombinant hybrids retain heterozygosity at many loci: new insights into the genomics of reproductive isolation in Populus
The maintenance of species barriers in the face of gene flow is often thought to result from strong selection against intermediate genotypes, thereby preserving genetic differentiation. Most… Expand
