The evolution of Ericaceae flowers and their pollination syndromes at a global scale.

American-Eurasian journal of botany, 2023
PREMISE OF THE STUDY Floral evolution in large clades is difficult to study not only because of the number of species involved, but also because they often are geographically widespread and include a diversity of outcrossing pollination systems.

Relationship between Pollination Syndromes, Pollen Morphology and Plant Ecology in Quaternary Deposits of the Cerrado

Palynology, 2023
This study presents morphological descriptions and ecological information for 58 terrestrial pollen taxa and seven water-related pollen taxa from the Brazilian Cerrado, obtained from two sediment cores, Lake Feia (LFB1) and Getulio Swamp (VGE-17 ...

Pollination syndromes in a specialised plant-pollinator interaction: does floral morphology predict pollinators in Calceolaria?

Plant Biology, 2015
AbstractPollination syndromes are defined as suites of floral traits evolved in response to selection imposed by a particular group of pollinators (e.g., butterflies, hummingbirds, bats). Although numerous studies demonstrated their occurrence in plants pollinated by radically different pollinators, it is less known whether it is possible to identify ...

Does pollination syndrome reflect pollinator efficiency in Silene nutans?

Acta Oecologica, 2020
Abstract Despite the specialization of floral traits towards particular floral visitors (pollination syndrome), insect-pollinated plants can display generalist rather than specialist interactions with their pollinators. This is the case of several Silene species that were viewed as nocturnally pollinated but are factually visited, and then ...

Darwin’s inflorescence syndrome is indeed associated with bee pollination

Plant Reproduction, 2023
A relationship between vertical acropetal inflorescences with protandrous flowers and bee pollination was hypothesized by Darwin back in 1877. Here we provide empirical evidence supporting this association across the angiosperms. Plant reproduction is not only determined by flower traits but also by the arrangement of flowers within inflorescences ...

The genetic dissection of floral pollination syndromes

Current Opinion in Plant Biology, 2006
A major factor in the evolution of the angiosperms is the adaptation of plants to animal pollinators. The specific morphology of a flower, its color, nectar composition and scent production can all contribute to reproductive success by attracting pollinators and by limiting out-crossing with other species.

Pollinator specialization and pollination syndromes of three related North AmericanSilene

Ecology, 2009
Community and biogeographic surveys often conclude that plant–pollinator interactions are highly generalized. Thus, a central implication of the pollination syndrome concept, that floral trait evolution occurs primarily via specialized interactions of plants with their pollinators, has been questioned. However, broad surveys may not distinguish whether

Pollination biology of Annona squamosa L. (Annonaceae): Evidence for pollination syndrome

Scientia Horticulturae, 2012
Abstract Pollination biology of Annona squamosa was investigated in the context of functional specialization and pollination syndrome. Hermaphroditic flower exhibited protogynous dichogamy as stigma became receptive a day before anther dehiscence. Flowers produce moderately high number (16,280 ± 324) of spherical and medium size (98.6 μm × 87.3 μm ...

Testing pollination syndromes in Melastomataceae

2021
The concept of pollination syndromes is used to study and analyze convergences in floral trait combinations across flowering plants. Pollination syndromes are based on the assumption that pollinators with similar behavior, morphology and sensory system (functional group) exert similar selective pressure on a flower, leading to convergent floral ...

The pollination syndrome ofDeplanchea tetraphylla (Bignoniaceae)

Plant Systematics and Evolution, 1986
The reproductive structures ofDeplanchea tetraphylla (Bignoniaceae) exhibit a significant number of unusual features: inflorescence with an apical “platform”; flowers yellow, short-tubed, strongly zygomorphic; mouth closed through lateral compression; stamens and style long-exserted, erect or slightly reclined; nectar dark brown, exposed in the spoon ...
