Pollinators of Oxypetalum (Asclepiadaceae) in Southeastern Brazil
(Revista Brasileira de Biologia, 2017)
Evaluating the effects of pollinator-mediated interactions using pollen transfer networks: Evidence of widespread facilitation in south Andean plant communities
(Wiley Blackwell Publishing, Inc, 2016-05)
Information about the relative importance of competitive or facilitative pollinator-mediated interactions in a multi-species context is limited. We studied interspecific pollen transfer (IPT) networks to evaluate quantity ...
Temporal variation in pollinarium size after its removal in species of Bulbophyllum: a different mechanism preventing self-pollination in Orchidaceae
(Springer-verlag WienViennaAustria, 1999)
Pollination biology and breeding system of syntopic Adenocalymma nodosum and A. peregrinum (Bignonieae, Bignoniaceae) in the Brazilian savanna
(Elsevier B.V., 2016-08-01)
The tropical Bignoniaceae is mostly late-acting self-incompatible (LSI) and depends on a guild of medium to large sized bees for their pollination. Adenocalymma nodosum and A. peregrinum are syntopic shrubs in savanna areas ...
Reproductive systems and crossing potential in three species of Bulbophyllum (Orchidaceae) occurring in Brazilian 'campo rupestre' vegetation
(Springer-verlag WienViennaAustria, 1999)
Pollination ecology of two species of (Orchidaceae): novel mechanisms and underlying adaptations to hummingbird pollination
(2015)
Relationships among floral biology, floral micromorphology and pollinator behaviourin bird-pollinated orchids are important issues to understand the evolution of thehuge flower diversity within Orchidaceae. We aimed to ...
Pollinators and crossability as reproductive isolation barriers in two sympatric oil rewarding Calceolaria (Calceolariaceae) species
(Springer, 2017)
Pollinator species are widely accepted as an important factor in plant reproductive
isolation. Although mostly investigated in plants visited by different groups of
pollinators (e.g., hummingbirds vs bees), few studies ...
Is floral diversification associated with pollinator divergence? Flower shape, flower colour and pollinator preference in chilean Mimulus
(OXFORD UNIV PRESS, 2008-04)
Background and Aims Adaptation to different pollinators is thought to drive divergence in flower colour and morphology, and may lead to interspecific reproductive isolation. Floral diversity was tested for association with ...
Sistema reprodutivo de Oxypetalum appendiculatum Mart. e Oxypetalum banksii Roem. & Schult. subsp. banksii (Asclepiadaceae)
(Acta Botanica Brasilica, 2019)
