Brood care by male bumble bees.
Male Bombus griseocollis (Hymenoptera: Apidae) share in the brood care of nestmates by incubating pupae (usually during the first few days after they emerge as adults). Male posture during incubation of a pupa is identical to that observed for females. Pupae incubated by males were 4 degrees C-6 degrees C above the temperature of unincubated pupae. Although this increase was not as great as tha...
متن کاملWhat Currency Do Bumble Bees Maximize?
In modelling bumble bee foraging, net rate of energetic intake has been suggested as the appropriate currency. The foraging behaviour of honey bees is better predicted by using efficiency, the ratio of energetic gain to expenditure, as the currency. We re-analyse several studies of bumble bee foraging and show that efficiency is as good a currency as net rate in terms of predicting behaviour. W...
متن کاملAnimal Cognition: Bumble Bees Suffer ‘False Memories’
The existence of 'false memories', where individuals remember events that they have never actually experienced, is well established in humans. Now a new study reports that insects similarly form illusory memories through merging of memory traces.
متن کاملDecline and conservation of bumble bees.
Declines in bumble bee species in the past 60 years are well documented in Europe, where they are driven primarily by habitat loss and declines in floral abundance and diversity resulting from agricultural intensification. Impacts of habitat degradation and fragmentation are likely to be compounded by the social nature of bumble bees and their largely monogamous breeding system, which renders t...
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.
