Humans Share More Preferences for Floral Phenotypes With Pollinators Than With Pests

open access: yesFrontiers in Plant Science, 2021
Studies on the selection of floral traits usually consider pollinators and sometimes herbivores. However, humans also exert selection on floral traits of ornamental plants.

The effect of molecular, morphological and spectral reflectance evolution on nicotiana polyploids of different ages [PDF]

open access: yes, 2010
PhDInterspecific hybridisation accompanied by multiplication of chromosome number, or allopolyploidy, results in rapid genetic, epigenetic, chromosomal and morphological changes.

Convergence without divergence in North American red-flowering Silene

open access: yesFrontiers in Plant Science, 2022
Combinations of correlated floral traits have arisen repeatedly across angiosperms through convergent evolution in response to pollinator selection to optimize reproduction.

Floral Longevity of Paphiopedilum and Cypripedium Is Associated With Floral Morphology

open access: yesFrontiers in Plant Science, 2021
Floral longevity (FL) is an important trait influencing plant reproductive success by affecting the chance of insect pollination. However, it is still unclear which factors affect FL, and whether FL is evolutionarily associated with structural traits ...

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

open access: yesAnais 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 ...

Pollinator-Mediated Selection on Floral Traits of Primula tibetica Differs Between Sites With Different Soil Water Contents and Among Different Levels of Nutrient Availability

open access: yesFrontiers in Plant Science, 2022
Abiotic environmental factors are predicted to affect plant traits and the intensity of plant-pollinator interactions. However, knowledge of their potential effects on pollinator-mediated selection on floral traits is still limited.

Floral traits are associated with the quality but not quantity of heterospecific stigmatic pollen loads

open access: yesBMC Ecology, 2020
Background In flowering communities, plant species commonly share pollinators and therefore plant individuals receive heterospecific pollen (HP). However, the patterns of HP transfers can deviate from patterns of plant-pollinator visitations.

Effect of floral traits mediated by plant-soil feedback on the relationship between plant density and fecundity: Case study of Tamarix chinensis in the Yellow River Delta, China

open access: yesGlobal Ecology and Conservation, 2021
Density-dependent fecundity is important for the successful recruitment and reproduction of plant populations, especially for plants inhabiting saltmarshes with highly varied environmental gradients.

Ants as flower visitors : floral ant-repellence and the impact of ant scent-marks on pollinator behaviour [PDF]

open access: yes, 2012
As flower visitors, ants rarely benefit a plant, commonly disrupting pollination by deterring other flower visitors, or stealing nectar. This thesis examines three aspects of ant-flower interactions, focusing on the occurrence of floral traits that ...
