... considered together and the extent to which metabolic rates and frequency of gas exchange vary and co-vary across climatic gradients remains unclear. We tested the MCA and hygric hypotheses within a species of endemic Fijian bee, Homalictus fijiensis , and among four Fijian bee species across an altitudinal...

... with a vector memory allows insects to take novel shortcuts between their current location and the vector memory location. For example, a bee reaching an empty feeder may take a (novel) flight directly towards an alternative (known) feeder location ( Menzel et al., 2011 ); and an ant forced to make a detour...

... direction from the landmark in task 2 was opposite to that in task 1. The context in which task 2 took place was either the same as the task-1 context or different: being a short distance away, having different surrounding landmarks, and a different colour on the training table. After each task, the bees...

... information obtained from these environmental features is encoded in memory. This paper reviews recent progress by my colleagues and me towards understanding three specific aspects of this problem in honeybees: (1) how bees learn the spatial relationships among widely separated locations in a familiar terrain...

.... The temperatures recorded are commonly accepted as slight underestimates of actual values prior to capture due to passive cooling between capture and insertion of the thermocouple. Here we present laboratory experiments involving tethered flight which show that bees often warm up on cessation of flight...
