Using the social clown anemonefish Amphiprion ocellaris, whether individuals exhibited consistency in activity levels, boldness and sociability in a paired context, and whether these three behavioural traits were positively correlated within a single behavioural syndrome, was investigated. The results highlight that consistent individual differences in behaviour are expressed in a social fish a...

• We studied if monoamines underly variation in animal personality, crickets. Our monoamine manipulation via Fluphenazine lowered both boldness and exploration. show that effects can be dose- behaviour-dependent. Latency to emerge from shelter used as a measure of Behavioural results depend on the drug used. Despite prevalence research interest its underlying mechanisms are not yet fully unders...

Leptokurtic distributions of movement distances observed in field-release studies, in which some individuals move long distances while most remain at or near their release point, are a common feature of mobile animals. However, because leptokurtosis is predicted to be transient in homogeneous populations, persistent leptokurtosis suggests a population heterogeneity. We found evidence for a hete...

Recent studies have focused on the role of behavior in biological invasions. Individuals may differ consistently in time for several behavioral traits (personality) which covary (behavioral syndrome) resulting in different behavioral types, some of them favoring invasion. Social hymenopterans have a strong potential to be invaders and their success depends primarily on the foundresses' ability ...

Recently, there has been growing recognition that fish harvesting practices can have important impacts on the phenotypic distributions and diversity of natural populations through a phenomenon known as fisheries-induced evolution. Here we experimentally show that two common recreational angling techniques (active crank baits versus passive soft plastics) differentially target wild largemouth ba...

To investigate the link between personality and maximum food intake of inactive individuals, food-deprived three-spined sticklebacks Gasterosteus aculeatus at rest in their home compartments were provided with ad libitum prey items. Bolder individuals ate considerably more than shyer individuals, even after accounting for body size, while sociability did not have an effect. These findings suppo...

Individual animals, including fish, often differ consistently in their behaviours, which is known as personality. An individual’s values on the five axes of personality, are activity, aggression, anxiety, boldness, and sociality, come together form syndromes. The major syndromes, proactive or reactive, characterize an expected behaviour. cunner wrasse, (Tautogolabrus adspersus), only warm-water...
