Breeding systems of Bromeliaceae species: evolution of selfing in the context of sympatric occurrence
Co-occurring congener plant species in the highly diverse Atlantic forests of southeastern Brazil may act as natural laboratories for evaluating evolution of reproductive shifts. We assessed theExpand

Cladistic Relationships of Aechmea (Bromeliaceae, Bromelioideae) and Allied Genera
Aechmea (ca. 220 species) is the largest and most diverse genus in Bromelioideae (Bromeliaceae), and several dissimilar generic concepts and infrageneric classifications have been proposed,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 callExpand

Reproductive biology and natural hybridization between two endemic species of Pitcairnia (Bromeliaceae).
We investigated pollination biology and breeding systems in hybridizing populations of Pitcairnia albiflos and P. staminea; both species are endemic to rocky outcrops at Rio de Janeiro, Brazil. TheseExpand

An apparent lack of prezygotic reproductive isolation among 42 sympatric species of Bromeliaceae in southeastern Brazil
The Atlantic rainforest in southeastern Brazil is one the main centers of diversification of Bromeliaceae. Empirical estimates of the relative importance of different pre- and postzygotic barriers toExpand

Bromeliaceae diversity and conservation in Minas Gerais state, Brazil
Field work and data from herbaria collections (2686 records) representing 283 taxa (265 species and 18 infraspecific taxa) of Bromeliaceae occurring at Minas Gerais state, southeastern Brazil, wereExpand

Selfing facilitates reproductive isolation among three sympatric species of Pitcairnia (Bromeliaceae)
Abstract. The reproductive biology of three sympatric species Pitcairniaflammea, P. corcovadensis and P. albiflos (Bromeliaceae) was studied on Corcovado Mountain in the city of Rio de Janeiro,Expand

Phylogenetic Relationships in Bromeliaceae Subfamily Bromelioideae based on Chloroplast DNA Sequence Data
Abstract Of the eight subfamilies currently recognized in Bromeliaceae, Bromelioideae is perhaps the most poorly understood. Generic circumscriptions are unclear, and an exceptionally diverseExpand

High abundance of dioecious plants in a tropical coastal vegetation.
We examined the frequency of hermaphroditic, monoecious, and dioecious species of angiosperms in restinga (sandy coastal plain) vegetation in SE Brazil. The study site was a vegetation mosaicExpand
