The study of individual behavioral variation, sometimes called animal personalities or
behavioral types, is now a well-established area of research in behavioral ecology and …

Highlights•Many behavioural and physiological studies quantify broad sense 'repeatability'.•'
Repeatability'estimates whether individual trait scores are maintained over time.•R (an …

Science requires replication. The development of many cloned or isogenic model organisms
is a testament to this. But researchers are reluctant to use these traditional animal model …

The study of animal personality variation promises to provide significant new insight into the
way that behavior evolves in animals, along with its ecological and evolutionary influences …

Abstract Knowledge on animal personality has provided new insights into evolutionary
biology and animal ecology, as behavioural types have been shown to affect fitness. Animal …

While there are now a number of theoretical models predicting how consistent individual
differences in behaviour may be generated and maintained, so far, there are few empirical …

Intraspecific competition is a major force in mediating population dynamics, fuelling
adaptation, and potentially leading to evolutionary diversification. Among the evolutionary …

Highlights•The role of recent social conditions on boldness repeatability is tested in
fish.•Social isolation before individual trials had a positive effect on repeatability.•Recent …

Highlights•Repeated social interactions may generate individual differences in social
behaviour.•Familiar groups did not show greater between-individual variation in …

Using social groups (ie schools) of the tropical damselfish Chromis viridis, we test how
familiarity through repeated social interactions influences fast-start responses, the primary …
