Floral 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...
متن کاملSocial transmission of nectar-robbing behaviour in bumble-bees.
Social transmission of acquired foraging techniques is rarely considered outside of a vertebrate context. Here, however, we show that nectar robbing by bumble-bees (Bombus terrestris)-an invertebrate behaviour of considerable ecological significance-has the potential to spread through a population at the accelerated rates typical of social transmission. Nectar robbing occurs when individuals ei...
متن کاملSocial Learning: Nectar Robbing Spreads Socially in Bumble Bees
Social transmission of learned behaviour is well documented in vertebrates but much less so among invertebrates. New research shows that nectar robbing can spread socially among bumble bees, even in the absence of nectar-robbing models.
متن کاملYeasts in nectar of an early-blooming herb: sought by bumble bees, detrimental to plant fecundity.
Through their effects on physicochemical features of floral nectar, nectar-dwelling yeasts can alter pollinator behavior, but the effect of such changes on pollination success and plant reproduction is unknown. We present results of experiments testing the effects of nectar yeasts on foraging patterns of captive and free-ranging bumble bees, and also on pollination success and fecundity of the ...
متن کاملForaging responses of bumble bees to rewardless floral patches: importance of within-plant variance in nectar presentation
Spatiotemporal variation in nectar distribution is a key factor affecting pollinator movements between flowers and plants within a population. Pollinators having systematic searching ability can flexibly respond to the reward condition of floral patches, and they tend to revisit rewarding patches. However, foraging behaviour may be influenced by the nectar distribution within populations. To ev...
