Why do females of so many socially monogamous species regularly engage in matings
outside the pair bond? This question has puzzled behavioural ecologists for more than two …

Within populations, individuals often show repeatable variation in behaviour, called 'animal
personality'. In the last few decades, numerous empirical studies have attempted to …

Human‐altered environmental conditions affect many species at the global scale. An
extreme form of anthropogenic alteration is the existence and rapid increase of urban areas …

Research on mate choice has primarily focused on preferences for quality indicators,
assuming that all individuals show consensus about who is the most attractive. However, in …

In evolutionary and behavioural ecology, increasing attention is being paid to the fact that
functionally distinct behaviours are often not independent from each other. Such …

In many species that form socially monogamous pair bonds, a considerable proportion of the
offspring is sired by extrapair males. This observation has remained a puzzle for …

A crucial assumption of animal personality research is that behaviour is consistent over time,
showing a high repeatability within individuals. This assumption is often made, sometimes …

A major challenge in behavioural and evolutionary ecology is to understand the evolution
and maintenance of consistent behavioural differences among individuals within …

A key question in evolutionary behavioural ecology is how species cope with changes in
their environments. In the last centuries, humans have caused dramatic changes in our …

Assessing behavioural consistency is crucial to understand the evolution of personality
traits. In the present study, we examined the short‐and long‐term repeatability and stability …
