“…However, studies exploring how individual differences in social information use (especially in a mate choice context) relate to individual differences in personality traits are scarce [64] and no study to date has made an attempt to link variation in males' tendency to show MCC to variation in personality traits but see [65] for an investigation of the link between personality and female MCC in zebra finches. In our study, we explored the relationship between male MCC and three behavioral parameters that are widely used to characterize animal personality in fish, namely boldness [66][67][68][69][70], activity [42,68,70,71] and sociability [68,69,[72][73][74].…”

“…Especially early life experience was found to influence boldness in fish (Chapman et al 2010). A previous study on Atlantic mollies (P. mexicana, the maternal ancestor of P. formosa) found variation in a trait associated with boldness (time to emerge from shelter) to be almost entirely phenotypically plastic (i.e., to be shaped by ecological habitat differences; Riesch et al 2009) and to be lost in common garden-reared fish (but see Brown et al 2007a;Dingemanse et al 2009 for heritability of boldness traits in other fishes). In their natural habitats, P. formosa and its sexual host species form mixed shoals (Schlupp and Ryan 1996).…”

“…In their natural habitats, P. formosa and its sexual host species form mixed shoals (Schlupp and Ryan 1996). Therefore, both species are equally exposed to ecological factors influencing boldness, like predation and resource availability (Brown and Braithwaite 2004;Ward et al 2004;Brown et al 2005Brown et al , 2007aRiesch et al 2009). Brown and Braithwaite (2004) reported an effect of body size on boldness traits in another poeciliid fish, the Panamanian bishop Brachyrhaphis episcopi, and this effect was also documented in the eastern mosquitofish Gambusia holbrooki ).…”

Examination of boldness traits in sexual and asexual mollies (Poecilia latipinna, P. formosa)

Considering the high costs of sexual reproduction (e.g., the production of males), its maintenance and predominance throughout the Animal Kingdom remain elusive. Especially the mechanisms allowing for a stable coexistence of closely related sexual and asexual species are still subject to a lively debate. Asexuals should rapidly outnumber sexuals due to higher population growth rates, unless they face some disadvantages. Here, we investigate potential differences in feeding behavior in a system of sexual (sailfin mollies, Poecilia latipinna) and coexisting gynogenetic fishes (Amazon mollies, Poecilia formosa). In two different experiments, we tested for differences in behavioral traits associated with boldness. Bold individuals take higher risks for gains in resources, so shyer individuals should be less competitive. Our study was motivated by the recent finding that P. formosa are less likely to be preyed upon by piscine predators than P. latipinna. We asked whether this result is indicative of low boldness in P. formosa. However, no differences between the two species were detectible in our behavioral experiments measuring (a) time to emerge from shelter to explore a novel environment, (b) latency time until feeding in a novel environment, and (c) recovery time until feeding restarted after a simulated predator attack. Furthermore, different boldness measures were not correlated with each other within individuals.

Boldness as a consistent personality trait in the noble crayfish, Astacus astacus

et al. 2010

Consistent individual differences in behavioural responses to perceived predation risk may have extensive ecological and evolutionary implications. We studied the repeatability of boldness across time and its relation to resource holding potential in the noble crayfish, Astacus astacus L., using predator-naïve immature individuals. We followed individual's shelter use both with and without exposure to the chemical and physical cues of predators, and with and without the presence of a conspecific. In addition, we examined if armament, i.e. relative chelae size, would be correlated with individual differences in behaviour. Individuals showed repeatable behaviours across time and context. Individuals that occupied the shelter in competitive dyadic tests also spent more time in the shelter during individual control observations, suggesting that boldness is a personality trait that does not necessarily relate positively to high resource holding potential in the noble crayfish. The relative size of chelae did not correlate with any of the measured behavioural variables. Our results suggest that boldness can be considered as individually consistent and ecologically important personality trait in the noble crayfish.
