Bees associate colour cues with differences in pollen rewards.
In contrast to the wealth of knowledge concerning sucrose-rewarded learning, the question of whether bees learn when they collect pollen from flowers has been little addressed. The nutritional value of pollen varies considerably between species, and it may be that bees learn the features of flowers that produce pollen best suited to the dietary requirements of their larvae. It is still unknown,...
متن کاملRed mason bees cannot compete with honey bees for floral resources in a cage experiment
Intensive beekeeping to mitigate crop pollination deficits and habitat loss may cause interspecific competition between bees. Studies show negative correlations between flower visitation of honey bees (Apis mellifera) and wild bees, but effects on the reproduction of wild bees were not proven. Likely reasons are that honey bees can hardly be excluded from controls and wild bee nests are general...
متن کاملColour and emotion: children also associate red with negative valence.
The association of colour with emotion constitutes a growing field of research, as it can affect how humans process their environment. Although there has been increasing interest in the association of red with negative valence in adults, little is known about how it develops. We therefore tested the red-negative association in children for the first time. Children aged 5-10 years performed a fa...
متن کاملBumble bees forage widely for species - rich floral patches
PNAS u January 8, 2013 u vol. 110 u no. 2 u 385–386 www.pnas.org/cgi/doi/10.1073/iti0213110 Studies in rats and mice have suggested that the metabotropic glutamate receptor 5 (mGluR5) plays a key role in mediating addiction and substance abuse, but whether the receptor plays a role in human addiction has been unclear. Funda Akkus et al. (pp. 737– 742) used positron emission tomography to measur...
متن کاملFloral Nectar Guide Patterns Discourage Nectar Robbing by Bumble Bees
Floral displays are under selection to both attract pollinators and deter antagonists. Here we show that a common floral trait, a nectar guide pattern, alters the behavior of bees that can act opportunistically as both pollinators and as antagonists. Generally, bees access nectar via the floral limb, transporting pollen through contact with the plant's reproductive structures; however bees some...
