The effect of polyploidy and hybridization on the evolution of floral colour in Nicotiana (Solanaceae). [PDF]

open access: yes, 2015
Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization ...

Phenotypic Selection on Flower Color and Floral Display Size by Three Bee Species

open access: yesFrontiers in Plant Science, 2021
Plants exhibit a wide array of floral forms and pollinators can act as agent of selection on floral traits. Two trends have emerged from recent reviews of pollinator-mediated selection in plants.

Ant species identity mediates reproductive traits and allocation in an ant-garden bromeliad [PDF]

open access: yes, 2011
Background and Aims Determining the sources of variation in floral morphology is crucial to understanding the mechanisms underlying Angiosperm evolution.

Floral signals evolve in a predictable way under artificial and pollinator selection in Brassica rapa

open access: yesBMC Evolutionary Biology, 2020
Background Angiosperms employ an astonishing variety of visual and olfactory floral signals that are generally thought to evolve under natural selection. Those morphological and chemical traits can form highly correlated sets of traits.

Petal Morphology Is Correlated with Floral Longevity in Paeonia suffruticosa

open access: yesAgronomy, 2023
Floral longevity (FL) is an important floral functional trait which is critical for flowering plants. FL shows great diversity among angiosperms; however, there is limited information on the mechanisms that influence differences in floral longevity ...

The FloRes Database: A floral resources trait database for pollinator habitat-assessment generated by a multistep workflow [PDF]

open access: yesBiodiversity Data Journal, 2022
The decline of pollinating insects in agricultural landscapes proceeds due to intensive land use and the associated loss of habitat and food sources. The feeding of those insects depends on the spatial and temporal distribution of nectar and pollen as ...

FLORAL TRAITS IN CASTILLEJA

open access: yes, 2022
One of the major goals of evolutionary biology is to explain trait variation within and among species. Much of the tremendous diversity in floral traits across angiosperm lineages is thought to reflect a history of close ecological associations with animals.

Florivory shapes both leaf and floral interactions

open access: yesEcosphere, 2016
Florivory, or the consumption of flowers, is a ubiquitous interaction that can reduce plant reproduction directly by damaging reproductive tissues and indirectly by deterring pollinators.

Testing Pollination Syndromes in Oenothera (Onagraceae)

open access: yesJournal 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.

The effect of flower position on variation and covariation in floral traits in a wild hermaphrodite plant

open access: yesBMC Plant Biology, 2010
Background Floral traits within plants can vary with flower position or flowering time. Within an inflorescence, sexual allocation of early produced basal flowers is often female-biased while later produced distal flowers are male-biased.
