Personality affects zebra finch feeding success in a producer-scrounger game

Recent evidence strongly suggests that natural selection can favour the evolution of consistent individual differences in behaviour ([`]personalities’). Indeed, personality shows heritable variation and has been linked to fitness in many species. However, the fitness effects of personality are highly variable within and between species. Furthermore, the nature of the causal influence of personality on […]

Personality predicts decision making only when information is unreliable

Phenotypic plasticity in decision making should be selected for when reliable information on current conditions is available. When current information is unreliable, however, selection should favour unresponsive behavioural phenotypes, which might lead to the emergence of personalities. We tested the hypothesis that personality will affect decision making when information is unreliable, but not when it […]
