Animal Behaviour: Task Differentiation by Personality in Spider Groups
نویسندگان
چکیده
In social animals, group efficiency is often assumed to increase with task differentiation, but this requires that individuals are better than generalists at the task they specialize in. A new study finds that individual Anelosimus studiosus spiders do predominantly perform the task they excel at, in line with their individual personality type, when they are placed in groups.

Individual personalities shape task differentiation in a social spider.
Deciphering the mechanisms involved in shaping social structure is key to a deeper understanding of the evolutionary processes leading to sociality. Individual specialization within groups can increase colony efficiency and consequently productivity. Here, we test the hypothesis that within-group variation in individual personalities (i.e. boldness and aggression) can shape task differentiation...

متن کاملParticipation in cooperative prey capture and the benefits gained from it are associated with individual personality
In animal societies, behavioral idiosyncrasies of the individuals often guide which tasks they should perform. Such personality-specific task participation can increase individual task efficiency, thereby improving group performance. While several recent studies have documented group-level benefits of within-group behavioral (i.e., personality) diversity, how these benefits are realized at the ...
متن کاملRecent social conditions affect boldness repeatability in individual sticklebacks
Animal personalities are ubiquitous across the animal kingdom and have been shown both to influence individual behaviour in the social context and to be affected by it. However, little attention has been paid to possible carryover effects of social conditions on personality expression, especially when individuals are alone. Here we investigated how the recent social context affected the boldnes...
متن کاملPersistent social interactions beget more pronounced personalities in a desert-dwelling social spider.
The social niche specialization hypothesis predicts that repeated social interactions will generate social niches within groups, thereby promoting consistent individual differences in behaviour. Current support for this hypothesis is mixed, probably because the importance of social niches is dependent upon the ecology of the species. We test whether repeated interactions among group mates gener...
