Crab spiders (Araneae: Thomisidae) in flowering plants in a Brazilian "Cerrado" ecosystem [PDF]

Brazilian Journal of Biology, 2011
Although crab spiders are common in flowering plants, their relations with plant species and its floral traits have been poorly known in the Neotropics. Observations regarding plant habits, floral visitors and also floral characteristics such as anthesis,

The associations between floral traits and pollinator groups in two Mediterranean mountainous plant communities in the Middle Atlas of Morocco [PDF]

BMC Ecology and Evolution
Background The relationships between floral traits and pollinators have been extensively studied over the last few decades. The concept of pollination syndrome suggests that plants pollinated by the same group of pollinators tend to develop similar ...

Floral ecology of Puya ctenorhyncha (Bromeliaceae) an endemic plant of Bolivia

Botan‪ical Sciences, 2023
Background: The terrestrial bromeliad Puya ctenorhyncha is a near-threatened endemic species that grows between 2,500-4,050 m asl. Hypotheses: Hummingbirds are the most important visitors of this plant given its morphological and floral traits. Study

Testing Pollination Syndromes in Oenothera (Onagraceae)

Journal of Pollination Ecology, 2021
Pollinators are considered a major selective force in shaping the diversification of angiosperms. It has been hypothesized that convergent evolution of floral form has resulted in “pollination syndromes” - i.e.

Different influences of phylogenetically conserved and independent floral traits on plant functional specialization and pollination network structure

Frontiers in Plant Science, 2023
Plant specialization and pollination network structure play important roles in community assembly. Floral traits can mediate plant–pollinator interactions and thus have important impacts on nestedness and modularity of pollination network.

Style lateral bending and its pollination adaptation in Gyrocheilos (Gesneriaceae)

Guangxi Zhiwu, 2023
Gyrocheilos is a small genus of Gesneriaceae endemic to hight altitude mountains in Southwest China and Guangdong Province, with only five species. This genus is characterized by laterally bending style, which curves 90° at the top of the style and the ...

Evolution of Bird and Insect Flower Traits in Fritillaria L. (Liliaceae)

Frontiers in Plant Science, 2021
Pollinators are often perceived as a primary selective agent influencing flower traits such as colour, size, and nectar properties. The genus Fritillaria L.

A few essential genetic loci distinguish Penstemon species with flowers adapted to pollination by bees or hummingbirds.

PLoS Biology, 2023
In the formation of species, adaptation by natural selection generates distinct combinations of traits that function well together. The maintenance of adaptive trait combinations in the face of gene flow depends on the strength and nature of selection ...

Rethinking the pollination syndromes in Hymenaea (Leguminosae): the role of anthesis in the diversification

Anais da Academia Brasileira de Ciências, 2021
Floral traits associated with functional groups of pollinators have been largely employed to understand mechanisms of floral diversification. Hymenaea is a monophyletic legume genus widely recognized to being bat-pollinated, with nocturnal anthesis and ...

Genetic architecture of pollination syndrome transition between hummingbird-specialist and generalist species in the genus Rhytidophyllum (Gesneriaceae) [PDF]

PeerJ, 2015
Adaptation to pollinators is a key factor of diversification in angiosperms. The Caribbean sister genera Rhytidophyllum and Gesneria present an important diversification of floral characters.
