Social interactions with conspecifics are key to the fitness of most animals and, through the
transmission opportunities they provide, are also key to the fitness of their parasites. As a …

Highlights•We studied the effects of ontogeny and personality on inhibitory control in a

Within populations, there commonly exists consistent among-individual differences in
behaviour. As a potential mechanism maintaining this variation, the pace-of-life-syndrome …

Personality is now recognized as an ecologically and evolutionarily significant phenomenon
because it can affect fitness directly. However, empirical studies specifically tackling the …

The relations of temperament dimensions obtained in tests traditionally used to assess
interindividual differences with long-term behaviors and social rank of animals are poorly …

Considerable interindividual variation in behaviour, including learning ability and
personality, exists within populations. Recent research has suggested that these two traits …

Understanding how genetic variation is maintained in ecologically important traits is a
fundamental question in evolutionary biology. Male Trinidadian guppies (Poecilia reticulata) …

There is a burgeoning interest in studying consistent individual differences in animal
behaviour. Most studies consider mainly males, but sexes are subject to distinct selection …

Within populations, individual animals vary considerably in their behaviour, including mate
choice and personality. There is mounting interest in the potential covariation between these …

The aim of this study was to evaluate the feeding activity and the rhythm of daily locomotor
activity of the convict cichlid (Amatitlania sp.) kept in different social groups under a self …
