Consistency in the strength of laterality in male, but not female, guppies across different behavioural contexts

Laterality, the division of brain functions into separate hemispheres, is widespread across animal taxa. Lateralized individuals exhibit cognitive advantages yet substantial variation in laterality exists, particularly between the sexes. Why variation is maintained is unknown as few studies consider differences in lateralized behaviours between the sexes, and their underlying selection pressures, across different contexts. We investigated if...
