Flies and Flowers II: Floral Attractants and Rewards

Journal of Pollination Ecology, 2014
This paper comprises Part II of a review of flower visitation and pollination by Diptera (myiophily or myophily). While Part I examined taxonomic diversity of anthophilous flies, here we consider the rewards and attractants used by flowers to procure ...

Crop Domestication Alters Floral Reward Chemistry With Potential Consequences for Pollinator Health [PDF]

Frontiers in Plant Science, 2018
Crop domestication can lead to weakened expression of plant defences, with repercussions for herbivore and pathogen susceptibility. However, little is known about how domestication alters traits that mediate other important ecological interactions in ...

Foraging bee species differentially prioritize quantity and quality of floral rewards. [PDF]

PNAS Nexus
Abstract Pollinator–plant interactions represent a core mutualism that underpins biodiversity in terrestrial ecosystems, and the loss of flowering plants is a major driver of pollinator declines. Bee attraction to flowers is mediated by both quantity of resources (the number of available flowers for exploration) and quality of resources (

Impacts of soil nutrition on floral traits, pollinator attraction, and fitness in cucumbers (Cucumis sativus L.)

Scientific Reports, 2022
Annual plants allocate soil nutrients to floral display and pollinator rewards to ensure pollination success in a single season. Nitrogen and phosphorus are critical soil nutrients whose levels are altered by intensive land use that may affect plants ...

Mutualist- and antagonist-mediated selection contribute to trait diversification of flowers [PDF]

PeerJ, 2022
Flowers are generally short-lived, and they all face a multidimensional challenge because they have to attract mutualists, compel them to vector pollen with minimal investment in rewards, and repel floral enemies during this short time window.

Floral reward production is timed by an insect pollinator [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2007
Interval timing—sensitivity to elapsing durations—has recently been found to occur in an invertebrate pollinator, the bumble-bee ( Bombus impatiens ). Here, bumble-bees were required to time the interval between the start of foraging in a patch of low-quality artificial flowers providing 25% sucrose and the ...

Exploitation of Strobilanthes ixiocephala (Acanthaceae) flower buds by bees

Journal of Pollination Ecology, 2021
Floral larceny by bees has been studied mostly in open flowers although it is also experienced in buds. Until now, only few studies have recorded larceny of unopened flowers.

Flower Production, Headspace Volatiles, Pollen Nutrients, and Florivory in Tanacetum vulgare Chemotypes

Frontiers in Plant Science, 2021
Floral volatiles and reward traits are major drivers for the behavior of mutualistic as well as antagonistic flower visitors, i.e., pollinators and florivores.

Pollinarium Morphology and Floral Rewards inBrazilian Maxillariinae (Orchidaceae) [PDF]

Annals of Botany, 2004
There is strong support for the monophyly of the orchid subtribe Maxillariinae s.l., yet generic boundaries within it are unsatisfactory and need re-evaluation. In an effort to assemble sets of morphological characters to distinguish major clades within this subtribe, the pollinarium morphology and floral rewards of representative Brazilian species of ...

Caffeine in Floral Nectar Enhances a Pollinator's Memory of Reward [PDF]

Science, 2013
Bees Get That Caffeine "Buzz" Caffeine improves memory in humans, millions of whom find that their daily dose enhances clarity, focus, and alertness. The human relationship with caffeine is relatively recent, however, and thus its impact on our brains is likely a by-product of its true ecological role.
