Bees do not use nearest-neighbour rules for optimization of multi-location routes.
Animals collecting patchily distributed resources are faced with complex multi-location routing problems. Rather than comparing all possible routes, they often find reasonably short solutions by simply moving to the nearest ...
Signatures of a globally optimal searching strategy in the three-dimensional foraging flights of bumblebees.
(Nature Publishing Group, 2016-07)

Unexpected rewards induce dopamine-dependent positive emotion-like state changes in bumblebees.
Whether invertebrates exhibit positive emotion-like states and what mechanisms underlie such states remain poorly understood. We demonstrate that bumblebees exhibit dopamine-dependent positive emotion-like states across ...
