Genetic and spatial variation in vegetative and floral traits across a hybrid zone. [PDF]

open access: yesAm J Bot, 2022
PremiseGenetic variation influences the potential for evolution to rescue populations from impacts of environmental change. Most studies of genetic variation in fitness-related traits focus on either vegetative or floral traits, with few on floral scent.

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.

AN ASSOCIATION BETWEEN A FLORAL TRAIT AND INBREEDING DEPRESSION [PDF]

open access: yesEvolution, 2000
Inbreeding depression is a general phenomenon that is well documented in many plants and animals. Furthermore, it is generally considered to be the driving force behind mating-system evolution. Traditionally, the focus has been on the mean level of inbreeding depression in populations.

Phenotypic selection on floral traits in an urban landscape [PDF]

open access: yesProceedings of the Royal Society B: Biological Sciences, 2018
Native species are increasingly living in urban landscapes associated with abiotic and biotic changes that may influence patterns of phenotypic selection. However, measures of selection in urban and non-urban environments, and exploration of the mechanisms associated with such changes, are uncommon.

The mean and variability of a floral trait have opposing effects on fitness traits [PDF]

open access: yesAnnals of Botany, 2016
Floral traits are essential for ensuring successful pollination and reproduction in flowering plants. In particular, style and anther positions are key for pollination accuracy and efficiency. Variation in these traits among individuals has been well studied, but less is known about variation within flowers and plants and its effect on pollination and ...

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.

Seasonal variation in the response of a monoecious crop to increased temperature and fertilizers

open access: yesFrontiers in Plant Science, 2022
Climate warming may affect the performance of plants directly through altering vegetative or reproductive traits, and indirectly through modifying interactions with their pollinators.
