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 ...

Fragrance chemistry, nocturnal rhythms and pollination “syndromes” in Nicotiana
Phytochemistry, 2003GC-MS analyses of nocturnal and diurnal floral volatiles from nine tobacco species (Nicotiana; Solanaceae) resulted in the identification of 125 volatiles, including mono- and sesquiterpenoids, benzenoid and aliphatic alcohols, aldehydes and esters. Fragrance chemistry was species-specific during nocturnal emissions, whereas odors emitted diurnally ...

3-D pollination syndromes in Aquilegia
2023Flowers of the genus Aquilegia are pentamerous and have two petaloid perianth whorls, of which the inner one is spurred; nevertheless, their morphology is highly diverse. In Asia and Europe pollinators are mostly bumblebees and bees, while in North America shifts to hummingbird and hawkmoth pollination have occurred.

The American Midland Naturalist, 2014
Abstract The red tubular flowers of Penstemon eatonii (Plantaginaceae) typify the classic pollination syndrome for hummingbirds. Bees are thought to diminish its seed siring potential, but we found that foraging female generalist bees (Apis, Anthophora) deposited substantial amounts of conspecific pollen on P. eatonii stigmas.

Pollination Fluctuations Drive Evolutionary Syndromes Linking Dispersal and Mating System
The American Naturalist, 2009The existence of a syndrome linking dispersal rate and mating system has long been debated in evolutionary ecology, especially in plants. Some verbal models hypothesize that the ability to self-fertilize may be associated with high dispersal, since completely outcrossing species cannot reproduce when they disperse to an empty destination site. However,

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 ...

Flora - Morphology, Distribution, Functional Ecology of Plants, 2006
Pollination of Cyclamen persicum (Primulaceae) was studied in two wild populations in Israel. Buzz-pollination proved to be extremely rare, and performed by a large Anthophora bee only. The most frequent pollinators were various unspecialized species of thrips (Thysanoptera) and hoverflies (Syrphidae).

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
1980
Recently I came across a paper on the pollination of the terrestrial orchid Listera ovata and I have observed with pleasure that the author also checked on the ’reverse’ side of pollination, viz. the question whether cross-pollination by insects is compulsory. This reminded me of the large list of Malesian orchids which Dr. J.J.
