Behavioural trait assortment in a social network: patterns and implications

Abstract: 24The social fine structure of a population plays a central role in ecological and 25 evolutionary processes. Whilst many studies have investigated how morphological traits 26 such as size affect social structure of populations, comparatively little is known about the 27 influence of behaviours such as boldness and shyness. Using information on social 28 interactions in a wild population of Trinidadian guppies (Poecilia reticulata) we construct 29 a social network. For each individual in the network we quantif… Show more

“…Most commonly, animals socially assort based on genetic relatedness to form family groups. However, social assortment and variation in interactions can also be determined by reproductive state [58], dominance rank [54,59], familiarity [60], behavioural traits [61], task [4,37,62], body size [63] and location [64]. In ants, the structure of interaction networks may depend on colony age, the amount of brood and stored food or ecological conditions such as seasonal changes.…”

“…Therefore, empirical studies of the processes that drive social network formation are crucial for our understanding of disease dynamics. A common mechanism of network formation is assortativity according to a certain trait, that is, individuals often tend to interact with others of similar phenotypes [21]. Just as common is the complementary mechanism, disassortativity, where individuals tend to interact with individuals of opposing phenotypes [22,23].…”

“…Individuals also associate selectively according to personality: guppies (Poecilia reticulata) that leave the shoal to inspect predators prefer to associate with others of the same behavioural type (Croft et al 2009). Third, sociability as a personality trait is likely to be an important factor in social interactions.…”
