American Journal of Botany, EarlyView.Abstract Premise Flowers that present their anthers and stigma in close proximity can achieve precise animal‐mediated pollen transfer, but risk self‐pollination. One evolutionary solution is reciprocal herkogamy. Reciprocity of anther and style positions among different plants (i.e., a genetic dimorphism) is common in distylous plants, but very rare in

Journal of Pollination Ecology, 2017 Biotic pollination is an important factor for ecosystem functioning and provides a substantial ecosystem service to human food security. Not all flower visitors are pollinators, however, and pollinators differ in their pollination performances.

Diversity, 2021 Small beetles are important pollinators of Annonaceae whose flower chambers are small and have diurnal and/or nocturnal anthesis. The pollinators of these flowers belong to the families Nitidulidae, Staphylinidae, Chrysomelidae, and Curculionidae.

The Capability of Some Butterflies as Carriers of Common Milkweed Pollen [PDF]
, 2017 The common milkweed, Asclepias syriaca L., is remarkably adapted for cross pollination by insects. Its pollen sacs (pollinia) are often found attached to the appendages of bees, wasps, butterflies, and other insects that visit milkweed for its nectar ...

Nested structure is dependent on visitor sex in the flower‒visitor networks in Kyoto, Japan
Ecology and Evolution, 2022 AbstractThe characteristics of flower‒visitor networks, comprised of multiple species interacting with each other, predict ecological and evolutionary processes. Intraspecific and interspecific variations in interaction patterns should affect network structures.

American Journal of Botany, EarlyView.Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Zygomorphic flowers have fewer visitors
, 2019 ABSTRACT Botanists have long identified bilaterally symmetrical (zygomorphic) flowers as having more specialized pollination interactions than radially symmetrical (actinomorphic) flowers. Zygomorphic flowers facilitate more precise contact with pollinators, guide pollinator behaviour, and exclude less effective pollinators. However, to our knowledge,

American Journal of Botany, EarlyView.Abstract Premise High‐latitude plants initiate flower primordia at least 1 year before flowering. While impacts of rising temperatures on phenology in the flowering year are well studied, the effects of warmer temperatures in the initiation year (IY; the year before flowering) are virtually unknown.

Journal of Pollination Ecology, 2011 Floral syndromes are traditionally thought to be associated with particular pollinator groups. Ornithophilous flowers tend to have traits that facilitate bird pollination such as having long, narrow, tubular corollas, often vivid coloration and diluted ...

Hand pollination to increase seed-set of red helleborine Cephalanthera rubra in the Chiltern Hills, Buckinghamshire, England [PDF]
, 2007 In 2007 and in previous years, as part of ongoing attempts to improve red helleborine Cephalanthera rubra seed-set, hand pollination of florets has been undertaken at a small colony of this species in Buckinghamshire, southern England.
