Gradual pollen release in a buzz‐pollinated plant: Investigating pollen presentation theory under bee visitation

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract The rate at which flowers dispense pollen across successive pollinator visits is a key functional trait influencing male reproductive success. Pollen presentation theory (PPT) predicts that when pollinators are abundant and actively groom their bodies to collect pollen,

The draft genome sequence of the Japanese honey bee, Apis cerana japonica (Hymenoptera: Apidae)

open access: yesEuropean Journal of Entomology, 2018
Honey bees are not only important for honey production but also as pollinators of wild and cultivated plants. The Eastern honeybee (Apis cerana) is more resistant to several pathogens than the Western honeybee (Apis mellifera), and the genomes of two ...

Infestation levels of Varroa destructor in local honey bees of Jordan [PDF]

open access: yes, 2008
To determine Varroa mite infestation levels in Jordan, a survey covering 180 colonies of two bee types (Apis m. syriaca and Apis m. syriaca hybrids) from six locations of 4 climatic zones was conducted during August, 8 month after the last treatment ...

The dose makes the poison: have “field realistic” rates of exposure of bees to neonicotinoid insecticides been overestimated in laboratory studies? [PDF]

open access: yes, 2014
Recent laboratory based studies have demonstrated adverse sub-lethal effects of neonicotinoid insecticides on honey bees and bumble bees, and these studies have been influential in leading to a European Union moratorium on the use of three neonicotinoids,

Temperature influences pollinators' choice of floral partners independently of community composition

open access: yesJournal of Animal Ecology, EarlyView.
This paper presents novel research that empirically demonstrates a direct link between temperature and plant–pollinator interaction patterns, independently of changes to community composition in either guild. We find that even without changes to community composition, pollinators including bumblebees exhibit different interactions across temperatures ...

Carbonic anhydrase from Apis mellifera: purification and inhibition by pesticides

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2017
Carbonic anhydrase (CA) enzymes have been shown to play an important role in ion transport and in pH regulation in several organisms. Despite this information and the wealth of knowledge regarding the significance of CA enzymes, few studies have been ...

Metabolomics-based biomarker discovery for bee health monitoring : a proof of concept study concerning nutritional stress in Bombus terrestris [PDF]

open access: yes, 2019
Bee pollinators are exposed to multiple natural and anthropogenic stressors. Understanding the effects of a single stressor in the complex environmental context of antagonistic/synergistic interactions is critical to pollinator monitoring and may serve ...
