The ontogeny of bumblebee flight trajectories: from naïve explorers to experienced foragers.

Understanding strategies used by animals to explore their landscape is essential to predict how they exploit patchy resources, and consequently how they are likely to respond to changes in resource distribution. Social bees provide a good model for this and, whilst there are published descriptions o...
