Organisation in eusocial insect colonies emerges from the decisions and actions of its individual members. In turn, these decisions and actions are influenced by the individual's behaviour (or temperament). Although there is variation in the behaviour of individuals within a colony, we know surprisingly little about how (or indeed if) the types of behaviour(More)
If the cognitive performance of animals reflects their particular ecological requirements, how can we explain appreciable variation in learning ability amongst closely related individuals (e.g. foraging workers within a bumble bee colony)? One possibility is that apparent ‘errors’ in a learning task actually represent an alternative foraging strategy. In(More)
Despite a presumed fitness advantage for individuals with well-developed cognitive abilities, learning performance is usually found to be highly variable within a population. Although little is currently known about the mechanisms responsible for maintaining such variation, there is correlative evidence to suggest that learning performance may be linked to(More)
