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...

We argue that financial analysts can be viewed as participants of two tournaments (the “All-star” tournament and the intrafirm tournament) and examine whether analysts are incentivized by the tournament compensation structure. Using data from 1991 to 2007, we find that interim losers are more likely to increase the boldness of their forecasts in the remainder of the tournament period than inter...

Despite increasing evidence of the importance repeatable among-individual differences in behaviour (animal personality) ecology and evolution, little remains known about role animal personalities sexual selection. Here, we present an investigation hypothesis that individuals their partners play a different episodes selection, extent to which these effects are modulated by social environment. We...

Intraspecific variation in personality traits is increasingly recognized as an important determinant of invasion success and associated with the dispersal ability several invasive species. However, previous studies have focused on species through continuous habitats, despite high levels anthropogenic fragmentation modern environments. This study investigated how influences behaviour aquatic at ...

Behavioral syndromes are widely recognized as important for ecology and evolution, but most predictions about ecological impacts are based on conceptual models and are therefore imprecise. Borrowing insights from the theory of demographic heterogeneity, we derived insights about the population-dynamic effects of behavioral syndromes. If some individuals are consistently more aggressive than oth...

The present study investigated how triarchic psychopathy domains are related to self-rated organizational citizenship behavior (OCB) and whether job attitudes, such as satisfaction affective commitment, mediate these relationships. Results from a sample of 434 employees indicated that OCB was positively correlated with boldness, negatively meanness, uncorrelated disinhibition. Structural equati...
