Discernment of bee pollen loads using computer vision and one-class classification techniques [PDF]
, 2012 In this paper, we propose a system for authenticating local bee pollen against fraudulent samples using image processing and classification techniques. Our system is based on the colour properties of bee pollen loads and the use of one-class classifiers ...

Journal of Pollination Ecology, 2023 Cucurbita pepo crops (pumpkin, squash) are entirely dependent upon insect pollinators for reproduction. In Ontario, Canada, their most important pollinator is the hoary squash bee (Eucera pruinosa), a wild ground-nesting, solitary bee whose only source ...

Diet characterisation of solitary bees on farmland: dietary specialisation predicts rarity [PDF]
, 2016 Changes in agricultural practice across Europe and North America have been associated with declines in wild bee populations. Bee diet breadth has been associated with sensitivity to agricultural intensification, but much of this analysis has been ...

Pollen-borne microbes shape bee fitness [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2019 Teeming within pollen provisions are diverse communities of symbiotic microbes, which provide a variety of benefits to bees. Microbes themselves may represent a major dietary resource for developing bee larvae. Despite their apparent importance in sustaining bee health, evidence linking pollen-borne microbes to larval health is currently lacking.

Bio-Functional Properties of Bee Pollen: The Case of “Bee Pollen Yoghurt” [PDF]
Coatings, 2018 The objectives of the present work were: (a) to characterize bee pollen from the region of Epirus in terms of biofunctional activity parameters as assessed by (i) the determination of specific polyphenols using high performance liquid chromatography electrospray ionization mass spectrometry (HPLC/ESI-MS), (ii) antioxidant capacity (DPPH assay), and ...

Effects of drying techniques on chemical composition and volatile constituents of bee pollen
Czech Journal of Food Sciences, 2020 Bee pollen is used as a food supplement by humans as it is rich in carbohydrates, proteins, lipids, vitamins, minerals and trace elements. Bee pollen has many biological activities such as antibacterial, antifungal, antitumor and antioxidant.

Spectroscopic Discrimination of Bee Pollen by Composition, Color, and Botanical Origin
Foods, 2021 Bee pollen samples were discriminated using vibrational spectroscopic methods by connecting with botanical sources, composition, and color. SEM and light microscope images of bee pollen loads were obtained and used to assess the botanical origin. Fourier

Megachile sculpturalis, the Giant Resin Bee, overcomes the blossom structure of Sunn Hemp (Crotalaria juncea) that impedes pollination [PDF]
, 2016 Bee species that are effective pollinators of sunn hemp (Crotalaria juncea L.: Fabaceae: Crotalarieae) are few in number because of the large size and papilionaceous structure of the plant’s blossom.
