The floral relationships existing between the mainly New World genus Sisyrinchium (Iridaceae) and oil-collecting bees were investigated in southern South America. In addition to a single species known before as producing ...

Bee pollen gathering from a few related plant species is a specialisation known as oligolecty. Although it is an extended phenomenon, it has been scarcely explored in oil-collecting bees. At the geographic level, there is ...

It is reported for the first time oil collecting by bees of the genus Caenonomada on flowers of Plantaginaceae. Females of Caenonomada unicalcarata were observed collecting oil on flowers of Angelonia cornigera, and males ...

Pollination interactions between plants bearing oil-flowers and oil-collecting bees are regarded as specialized, and within the major group of bees,oil-collecting bees are considered a special functional group of pollinators, ...

Pollinator species are widely accepted as an important factor in plant reproductive isolation. Although mostly investigated in plants visited by different groups of pollinators (e.g., hummingbirds vs bees), few studies ...

Pollinators' features, especially those with a functional role during the pollination process, have been shown to be a good predictor of pollen load for some bee species, but little is known about solitary bees. Here, I ...

Detailed studies on the distribution, structure, and secretion activity of floral glands are important to understand the relationship of flowers with oil-collecting bees in Malpighiaceae. Here, we characterised the floral ...
