Nectar guide fluctuating asymmetry does not relate to female fitness in Mimulus luteus
(2004)
Most studies assessing the importance of developmental instability of floral characters for pollinator visits and plant fitness have focused on the fluctuating asymmetry (FA) of the corolla phenotype. The importance of ...
Can plant hybridization and polyploidy lead to pollinator shift?
(Soc Botanica Brasil, 2020-04-01)
Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are ...
Floral micromorphology and nectar composition of the early evolutionary lineage Utricularia (subgenus Polypompholyx, Lentibulariaceae)
(2019-01-01)
Utricularia (Lentibulariaceae) is a genus comprising around 240 species of herbaceous, carnivorous plants. Utricularia is usually viewed as an insect-pollinated genus, with the exception of a few bird-pollinated species. ...
Self-Compatibility Not Associated with Morphological or Genetic Diversity Reduction in Oil-Rewarding Calceolaria Species
(MDPI Multidisciplinary Digital Publishing Institute, 2020-10)
One of the most common evolutionary transitions in angiosperms is the reproductive change from outcrossing to selfing, commonly associated with changes in floral biology and genetic diversity. Here, we aim to test whether ...
Floral scent evolution in the genus jaborosa (Solanaceae): Influence of ecological and environmental factors
(MDPI AG, 2021-08)
Floral scent is a key communication channel between plants and pollinators. However,the contributions of environment and phylogeny to floral scent composition remain poorly understood. In this study, we characterized ...
Crepuscular pollination and reproductive ecology of Trembleya laniflora (Melastomataceae), an endemic species in mountain rupestrian grasslands
(2018-01-01)
The “pollination syndrome” hypothesis predicts a direct relationship between a set of floral characters and the principal pollinating agent. The presence of flowers with poricidal anthers, heterostemony and pollen as the ...
Reproductive biology of Trichocentrum pumilum: an orchid pollinated by oil-collecting bees
(WILEY-BLACKWELL, 2011)
The reproductive biology, reward production and pollination mechanism of Trichocentrum pumilum were studied in a gallery forest in the interior of the State of Sao Paulo, southeast Brazil. The floral visitors and pollination ...
