Spectroscopic Discrimination of Bee Pollen by Composition, Color, and Botanical Origin
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

Widespread contamination of wildflower and bee-collected pollen with complex mixtures of neonicotinoids and fungicides commonly applied to crops [PDF]
There is considerable and ongoing debate as to the harm inflicted on bees by exposure to agricultural pesticides. In part, the lack of consensus reflects a shortage of information on field-realistic levels of exposure. Here, we quantify concentrations of

Megachile sculpturalis, the Giant Resin Bee, overcomes the blossom structure of Sunn Hemp (Crotalaria juncea) that impedes pollination [PDF]
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.

Conservation Conundrum: At-risk Bumble Bees (Bombus spp.) Show Preference for Invasive Tufted Vetch (Vicia cracca) While Foraging in Protected Areas [PDF]
In recent decades, some bumble bee species have declined, including in North America. Declines have been reported in species of bumble bees historically present in Ontario, including: yellow bumble bee (Bombus fervidus) (Fabricus, 1798), American bumble ...

Metric and Spectral Insight into Bee-Pollen-to-Bee-Bread Transformation Process
Due to numerous bioactive constituents, both bee pollen (BP) and bee bread (BB) represent valuable food supplements. The transformation of BP into BB is a complex biochemical in-hive process that enables the preservation of the pollen’s nutritional value. The aim of this study was to determine the depth of the honeycomb cells in which bees store pollen

Pollen elicits proboscis extension but does not reinforce PER learning in honeybees [PDF]
The function of pollen as a reward for foraging bees is little understood, though there is evidence to suggest that it can reinforce associations with visual and olfactory floral cues.
