...; their behaviour, colouration, transcriptome and stress responses also show a dramatic alteration when social status is altered ( Maruska, 2015 ). Huntingford (1976a , b ) found that there is a positive relationship between boldness and aggressive behaviour in the three-spined stickleback ( Gasterosteus...

... response of ectotherms to warming is associated with changes in brain morphology and function. Here, we compared aerobic metabolism, brain volume, boldness and accuracy of maze solving of common minnows ( Phoxinus phoxinus ) acclimated for 8 months to either their current optimal natural (14°C) or warm (20...

...-typical pheromone cues are entirely dependent on social experience with adult males. Experience with adults also shapes development along the shy–bold personality axis, with shy behaviors arising from exposure to risk-averse heterospecifics as a potential stress-coping strategy. In maturing females...

... ecosystems worldwide, where it may interfere with the behavior of exposed organisms. Fluoxetine exposure has been found to influence boldness and exploration in a range of fish species; however, how it might alter behavior in multiple contexts or over time is rarely examined. To this end, the effects...

... (‘swim’ reflected in sustained and sprint speeds). Together, muscle and swim had a significant positive effect on activity, and explained 71.8% of variation in the distance moved, time active and maximum voluntary speed in an open field. Activity had a significant positive effect on boldness, explaining...

... bolder behaviour than their late emerging littermates. Taken together, these results suggest that time of emergence, boldness and aggression are linked to each other, forming a behavioural syndrome in juvenile salmon. Differences in brain gene expression between early and late emerging salmon add further...
