Pollinator specialization and pollination syndromes of three related North AmericanSilene
Ecology, 2009Community 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

The evolution of Ericaceae flowers and their pollination syndromes at a global scale
American Journal of Botany, 2023AbstractPremiseFloral 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. The cosmopolitan blueberry family (Ericaceae) is one such example, most notably pollinated by bees and multiple ...

Darwin’s inflorescence syndrome is indeed associated with bee pollination
Plant Reproduction, 2023A 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 ecological pollination syndromes of insect‐pollinated plants in an alpine meadow
Ecological Research, 1986Abstract The insect pollination of an alpine plant community consisting of herbs and shrubs, was observed on Mt. Kisokoma‐ga‐take, central Honshu, Japan. There were two main groups of pollinators, syrphid flies and bumble bees. Although some shrubs were visited by both types of insects, other shrubs and the herbs were visited by ...

Pollination biology of Annona squamosa L. (Annonaceae): Evidence for pollination syndrome
Scientia Horticulturae, 2012Abstract 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 ...

Pollination Syndromes—The Evidence
2007AbstractThe concept of the pollination syndrome has underlain much of floral biology for many years. This chapter assesses the usefulness of the concept in understanding flowers and flowering. It begins by considering why and how the pollination syndrome concept has become so entrenched in the literature on flowering, and then examines whether the key ...

The pollination syndrome ofDeplanchea tetraphylla (Bignoniaceae)
Plant Systematics and Evolution, 1986The 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 ...

The pollination biology of Burmeistera (Campanulaceae): specialization and syndromes
American Journal of Botany, 2006The floral traits of plants with specialized pollination systems both facilitate the primary pollinator and restrict other potential pollinators. To explore interactions between pollinators and floral traits of the genus Burmeistera, I filmed floral visitors and measured pollen deposition for 10 species in six cloud forest sites throughout northern ...

Genomic and Molecular Bases of Pollination Syndrome Evolution
Annual Review of Plant BiologyThe transition from one pollination syndrome to another should be difficult as it requires coordinated changes of multiple component traits, with each involving multiple genes, yet these transitions occur frequently in nature. Here, we explore the genetic and genomic properties that facilitate such rapid pollination syndrome switches.

Pollination syndromes and pollinator shifts in melastomataceae
Angiosperm flowers have a large spectrum of animal pollinators including among others bees, flies, birds, and bats. Shifts between different functional groups of pollinators (e.g., from bees to hummingbirds) are thought to be key drivers of floral morphological diversity (disparity).openaire +1 more source
