Bold crickets have a shorter life

An individual’s behaviour in risky situations is a distinct personality trait that can have an immediate impact on longevity. Researchers from the Max Planck Institute for Ornithology in Seewiesen have now found differences in personality types for the first time in free living field crickets. Risk-prone individuals showed a higher mortality as they stayed more often outside their burrow where they can be easily detected by predators. Moreover, shy individuals are not encountered so often by researchers, causing potential bias in collected scientific data. This methodological problem has been neglected in many personality studies but has been accounted for uniquely in the present study.
