Nutritional state influences shoaling preference for familiars.
Preferences for grouping with familiar individuals are shown in many animal species, including the three-spined stickleback (Gasterosteus aculeatus). Shoaling with familiars is advantageous because of more precise anti-predator behaviours or more stable dominance hierarchies. Additionally, associations with familiar individuals facilitate the evolution of altruistic behaviour. Thus, in situatio...
متن کاملInfluence of genetic relatedness and shoal size on shoaling preferencesin juvenile Puntius sarana subnasutus (Hamilton Valenciennes).
When presented with stimulus shoals of siblings and conspecifics in equal number, P. sarana subnasutus were able to discriminate their siblings and preferred to associate with them. Given a choice between large shoal and a small shoal consisting of siblings, the juvenile fish preferred to associate with larger stimulus group to the smaller one. However, juveniles traded off their preference for...
متن کاملExperience influences shoal member preference in a species pair of sticklebacks
Recognition of suitable group members can be learned through experience or can be genetically based. To determine when learning may be important in social recognition, we compared the social recognition of juveniles and adults of 2 sympatric species of three-spined sticklebacks (Gasterosteus spp.). We altered the social environment of both species, rearing individuals with varying numbers of co...
متن کاملTiming and plasticity of shoaling behaviour in the zebrafish, Danio rerio.
The zebrafish has become a major model system for biomedical research and is an emerging model for the study of behaviour. While adult zebrafish express a visually mediated shoaling preference, the onset of shoaling behaviour and of this preference is unknown. To assess the onset of these behaviours, we first manipulated the early social environment of larval zebrafish subjects, giving them thr...
متن کاملHow selection affects phenotypic fluctuation
The large degree of phenotypic fluctuation among isogenic cells highlighted by recent studies on stochastic gene expression confers fitness on some individuals through a 'bet-hedging' strategy, when faced with different selective environments. Under a single selective environment, the fluctuation may be suppressed through evolution, as it prevents maintenance of individuals around the fittest s...
