A schematic summary showing the links between behaviour and life‐history observed by Nakayama, Rapp & Arlinghaus [Nakayama, S., 2017] in wild Eurasion perch ( Perca fluviatilis ). [Colour figure can be viewed at wileyonlinelibrary.com ].In Focus: Nakayama , S. , Rapp , T. & Arlinghaus , R. ( 2017 ) Fast–slow life history is correlated with individual differences in movements and prey selection in an aquatic predator in the wild . Journal of Animal Ecology , 86 , 192 – 201 . The pace‐of‐life syndrome hypothesis (POLS) suggests that individual behavioural variation co‐evolves with life‐history variation, causing individuals on a fast life‐history trajectory to display more active or bold personalities than individuals following a slow trajectory. In the present study, Nakayama, Rapp & Arlinghaus ([Nakayama, S., 2016]) followed the detailed movement patterns of wild Eurasian perch using acoustic telemetry and studied their relationships with life‐history traits inferred from scale samples. Consistent with POLS, individuals with greater reproductive effort changed more often between active and passive behavioural modes. Moreover, individuals growing fast as a juvenile stayed active longer and moved over greater distances when adult. This study shows compelling evidence for covariance between personality and pace‐of‐life in a natural population.
