AbstractPremiseAnimal pollination is critical to plant reproduction and may cause convergent evolution of pollination syndromes. Pollination syndromes in Castilleja have been distinguished based on floral traits and historical observations of floral visitors. Here we addressed these questions: (1) Can pollination syndromes be distinguished using floral

Relative pollination effectiveness of floral visitors of Pitcairnia angustifolia (Bromeliaceae)
American Journal of Botany, 2007The effectiveness of flower visitors as pollinators will determine their potential role as selective agents on flower traits. Pitcairnia angustifolia has floral characters that would fit pollination by long‐billed hummingbirds, and they should be the most effective pollinators for this plant.

The effects of floral microclimate on pollen viability and visitor behavior
Current BiologyFlowers represent intricate microcosms shaped by their physical, chemical, and micrometeorological properties. Both thermogenic and non-thermogenic flowers (passively heated by insolation) that present a warm microclimate have been shown to attract pollinators, but emerging evidence suggests that floral humidity can also serve as an attractive cue ...

Floral biology and flower visitors on subantarctic Campbell Island
New Zealand Journal of Botany, 2013Abstract Island plants often show reduced floral pigmentation and display size compared with mainland relatives, which is commonly thought to relate to a lack of specialized pollinators. Some species on New Zealand's subantarctic islands have spectacular, highly pigmented inflorescences, yet the depauperate insect

Identification of Floral Visitors ofIris nelsonii
Southeastern Naturalist, 2012Abstract Floral visitors of the homoploid hybrid species, Iris nelsonii (Abbeville Red Iris), were observed and identified in order to determine whether Abbeville Red Iris flowers are visited by similar floral visitors as its progenitor Iris species. The most common floral visitors to Abbeville Red Iris flowers were Archilochus colubris (Ruby-throated ...

Floral visitors and ant scent marks: noticed but not used?
Ecological Entomology, 20121. Bee behaviour when visiting flowers is mediated by diverse chemical cues and signals, from the flower itself and from previous visitors to the flower. Flowers recently visited by bees and hoverflies may be rejected for a period of time by subsequent bee visitors. 2.

Pollination efficiency of cockroaches and other floral visitors of Clusia blattophila
Plant Biology, 2019Abstract Cockroaches have rarely been documented as pollinators. In this paper we examine whether this is because they might be inefficient at pollination compared to other pollinators. Clusia blattophila, a dioecious shrub growing on isolated rocky outcrops in French Guiana, is pollinated by Amazonina platystylata cockroaches and provides a valuable

The effect of resource limitation on floral visitors of Monardella odoratissima
2019Fluctuating flowering patterns affect an environments floral abundance, impacting the spatial structure of nectar and pollen resources, ultimately influencing floral visitor foraging behavior. We examined the effect of reducing floral resources on floral visitors of Monardella odoratissima, commonly known as the mountain coyote mint.

Floral Visitor Profile and Their Relative Abundance on Buckwheat (Fagopyrum esclentum M.)
UTTAR PRADESH JOURNAL OF ZOOLOGYThe aim of the present study was to investigate the floral visitor profile, their reward forage from the inflorescence of buckwheat in addition to their abundance in different blooming phases of the crop. Totally 46 insect floral visitors were documented during different bloom phases during 2024, which included both Apis and non-Apis species, out of ...
