In the past decade, several conceptual papers have linked variation in animal personality to
variation in cognition, and recent years have seen a flood of empirical studies testing this …

Animal domestication leads to diverse behavioral, physiological, and neurocognitive
changes in domesticated species compared to their wild relatives. However, the widely held …

Having recognized that variation around the population-level “Golden Mean” of labile traits
contains biologically meaningful information, behavioural ecologists have focused …

Domestication is an evolutionary process during which the biobehavioural profile
(comprising eg social and emotional behaviour, cognitive abilities, as well as hormonal …

Natural selection can act on between-individual variation in cognitive abilities, yet
evolutionary responses depend on the presence of underlying genetic variation. It is …

Guinea pigs are included in various animal-assisted interventions (AAIs), but no research
has been published to date on behavioral changes in guinea pigs interacting with humans …

Highlights•Problem solving and social learning are stable traits in guinea pigs.•Associative
learning is not consistent across contexts.•Problem solving and social learning form a …

The intense selection of chickens for production traits, such as egg laying, is thought to
cause undesirable side effects and changes in behavior. Trade-offs resulting from energy …

Domestication is a process by which humans select some phenotypes of wild animal
species (ie, morphological traits or growth), but as all traits are linked, the selection of a …

Background Sexual selection has driven sexual dimorphism in agonistic behaviour in many
species. Agonistic behaviour is fundamentally altered by domestication and captivity, but it is …
