It has been suggested that individual behavioural traits influence the potential to successfully colonize new areas. Identifying the genetic basis of behavioural variation in invasive species thus represents an important step towards understanding the evolutionary potential of the invader. Here, we sequenced a candidate region for neophilic/neophobic and activity behaviour – the complete exon 3 of the DRD4 gene – in 100 Yellow‐crowned bishops (Euplectes afer) from two invasive populations in… 

The behavioural response of Great Tits to novel environment and handling is affected by the DRD4 gene

It is concluded that the same DRD4 gene variants affect behavioural responses in a controlled environment and wild contexts in the same directions, but that these relationships are not sex-speci fi c under standardized conditions.

DRD4 gene polymorphism in great tits: gender-specific association with behavioural variation in the wild

It is concluded that DRD4 gene polymorphism in wild birds can be associated with behaviour related to fearfulness, and this effect is supposedly gender-specific during the breeding time, potentially explained by sex differences in parental care or hormonal levels.

Selection on a behaviour‐related gene during the first stages of the biological invasion pathway

Pre‐establishment stages of a biological invasion do not only determine the number of propagules that are introduced (their quantity), but also their phenotypic and genetic characteristics (their quality).

Population differentiation and behavioural association of the two ‘personality’ genes DRD4 and SERT in dunnocks (Prunella modularis)

This work compared the genetic variation of the two ‘personality’ genes, DRD4 and SERT, between a native and an introduced population of dunnocks and found 38 significant associations between the two behavioural traits and the studied genes.

Personality and its fitness consequences in the Seychelles warbler (Acrocephalus sechellensis)

The results show that there are consistent among individual differences in behaviour in wild cooperative breeders that may be generated by future fitness potential and are associated with reproductive behaviour within the social pair.

Is there evidence of selection in the dopamine receptor D4 gene in Australian invasive starling populations

It is suggested that sequence data from putatively nonneutral loci are a useful addition to studies of invasive populations, where low genetic variability is expected.

A genetic perspective on rapid evolution in cane toads (Rhinella marina)

The dramatically rapid phenotypic evolution of cane toads in Australia has been accompanied by substantial shifts in gene expression, suggesting that this system is well suited to investigating the genetic underpinnings of invasiveness.

Mediterranean blue tits as a case study of local adaptation

Evidence suggesting that the striking phenotypic differentiation observed in Mediterranean blue tits is a fascinating case of local adaptation is reviewed, and it is argued that most phenotypically differentiated traits display heritable variation, a fundamental requirement for evolution to occur.

Rapid loss of antipredatory behaviour in captive-bred birds is linked to current avian invasions

Assessment of the response of wild-caught and captive-bred cage birds facing an approaching predator and their ability to escape from human capture offers a link between behaviour, fitness, and the invasion syndrome in birds.



Association between DRD4 gene polymorphism and personality variation in great tits: a test across four wild populations

The confirmation of an association between SNP830 genotype and personality‐related behaviour in a wild bird population warrants further research into potential fitness effects of the polymorphism, while also the population differences in the strength of the association deserve further investigation.

Variation in personality and behavioural plasticity across four populations of the great tit Parus major.

The findings imply that individual variation in both average level of behaviour and behavioural plasticity may generally characterize wild great tit populations and may largely be shaped by mechanisms acting within populations.

Drd4 gene polymorphisms are associated with personality variation in a passerine bird

It is suggested that an association between Drd4 gene polymorphisms and animal personality variation predates the divergence of the avian and mammalian lineages and heralds the possibility of following microevolutionary changes in frequencies of behaviourally relevantDrd4 polymorphisms within populations where natural selection acts differentially on different personality types.

Haplotype structure, adaptive history and associations with exploratory behaviour of the DRD4 gene region in four great tit (Parus major) populations

It is hypothesize that variation in exploratory and other dopamine‐related behaviour evolves locally by occasional adaptive shifts in the frequency of underlying genetic variants.

Personality traits and dispersal tendency in the invasive mosquitofish (Gambusia affinis)

It is found that mosquitofish display consistent behavioural tendencies over time, and significant positive correlations between all personality traits, suggesting personality-biased dispersal on an invasion front.

Realized heritability of personalities in the great tit (Parus major)

The great tit is bred, a classical model species for the study of behaviour under natural conditions, in captivity and the presence of considerable amounts of genetic variation for personality types in a wild bird is established.

Personality traits are related to ecology across a biological invasion

Behavioral differences among individuals are common and are organized into personalities in a wide variety of species. Hypotheses for the coexistence of behavioral differences fall into 3 categories:

Social Personality Polymorphism and the Spread of Invasive Species: A Model

A simulation model that integrates insights from life-history theory, animal personalities, network theory, and spatial ecology is used to derive a new mechanism for explaining variation in animal invasion success, showing that spread occurs most rapidly when a species includes a mix of life- history or personality types that differ in density-dependent performance and dispersal tendencies.

Exploratory behaviour and stressor hyper-responsiveness facilitate range expansion of an introduced songbird

It is suggested that certain behavioural and neuroendocrine traits may influence the ability of species to colonize novel habitats as well as native species shifting their ranges as climate conditions change.

DRD4 Genotype Predicts Longevity in Mouse and Human

The hypothesis that DRD4 gene variants contribute to longevity in humans and in mice is supported and it is suggested that this effect is mediated by shaping behavioral responses to the environment.
