Anther development in tribe Epidendreae: orchids with contrasting pollination syndromes [PDF]

open access: yesPeerJ, 2018
Background Epidendreae is one of the most diverse tribes among the orchids with remarkable variation in life form, floral morphology and pollination syndromes.

A global review of pollination syndromes: a response to ollerton et al. 2015 [PDF]

open access: yes, 2015
In a recent literature review, we demonstrated that the evolution of floral traits is driven by adaptation to the most effective pollinators. In a critique of this study, Ollerton et al.

Pollination syndromes in a Caatinga plant community in northeastern Brazil: seasonal availability of floral resources in different plant growth habits

open access: yesBrazilian Journal of Biology, 2014
To describe plant phenological patterns and correlate functioning for the quantity and quality of resources available for the pollinator, it is crucial to understand the temporal dynamics of biological communities.

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

open access: yesBMC 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 ...

A quantitative review of pollination syndromes: do floral traits predict effective pollinators? [PDF]

open access: yesEcology Letters, 2014
The idea of pollination syndromes has been largely discussed but no formal quantitative evaluation has yet been conducted across angiosperms. We present the first systematic review of pollination syndromes that quantitatively tests whether the most ...

Integrated Vegetative and Reproductive Traits Reveal Functional Groups and Assembly Mechanisms in a Subtropical Forest Ecotone [PDF]

open access: yesPlants
In species-rich forests, the integration of vegetative and reproductive traits defines plant ecological strategies and underpins community assembly. How these trait syndromes assemble into functional groups to facilitate species coexistence in ecotones ...

Pollination Syndromes: A Global Pattern of Convergent Evolution Driven by the Most Effective Pollinator

open access: yes, 2015
Convergent evolution of floral traits driven by pollinators has resulted in floral syndromes shared among different plant lineages. However, the flowers of many plant species are often visited by different pollinator groups, which apparently contradict ...

Selfing Can Facilitate Transitions between Pollination Syndromes [PDF]

open access: yesThe American Naturalist, 2018
Pollinator-mediated selection on plants can favor transitions to a new pollinator depending on the relative abundances and efficiencies of pollinators present in the community. A frequently observed example is the transition from bee pollination to hummingbird pollination.

Reconstructing an historical pollination syndrome: keel flowers [PDF]

open access: yesBMC Ecology and Evolution, 2022
AbstractBackgroundKeel flowers are bilaterally symmetrical, pentamerous flowers with three different petal types and reproductive organs enclosed by keel petals; generally there is also connation of floral parts such as stamens and keel petals. In this study, the evolution of keel flowers within the order Fabales is explored to investigate whether the ...
