“…Finally, it has recently Personality and the spread of invasion J. Cote et al 1577 been shown that the expression of personality might depend on group composition and even that the personality of others matters in the formation of a group (Harcourt et al 2009;Magnhagen & Bunnefeld 2009) and the behaviours of conspecifics also matter in dispersal decisions. More experiments are needed to test how individual social behaviour interacts with average social behaviour in the population.…”

Personality traits and dispersal tendency in the invasive mosquitofish (Gambusia affinis)

Ecological invasions, where non-native species spread to new areas, grow to high densities and have large, negative impacts on ecological communities, are a major worldwide problem. Recent studies suggest that one of the key mechanisms influencing invasion dynamics is personality-dependent dispersal: the tendency for dispersers to have a different personality type than the average from a source population. We examined this possibility in the invasive mosquitofish (Gambusia affinis). We measured individual tendencies to disperse in experimental streams and several personality traits: sociability, boldness, activity and exploration tendency before and three weeks after dispersal. We found that mosquitofish display consistent behavioural tendencies over time, and significant positive correlations between all personality traits. Most notably, sociability was an important indicator of dispersal distance, with more asocial individuals dispersing further, suggesting personality-biased dispersal on an invasion front. These results could have important ecological implications, as invasion by a biased subset of individuals is likely to have different ecological impacts than invasion by a random group of colonists.

“…For instance, consistent differences in activity and exploratory behaviour in Siberian chipmunks (Tamias sibiricus) predict tick infection risk because the activity patterns and space use of bold individuals make them more prone to encountering ticks in the environment [56]. In other systems, bolder individuals are more likely to interact with conspecifics (great tits, Parus major [57]), and the presence of bold individuals in a group can even attract new individuals to join (sticklebacks, Gasterosteus aculeatus [58]). Thus, across a suite of parasite transmission modes, bold animals may function as 'superreceivers', or individuals that are disproportionately more likely to acquire parasites than the general population.…”

Host behaviour–parasite feedback: an essential link between animal behaviour and disease ecology

et al. 2016

Animal behaviour and the ecology and evolution of parasites are inextricably linked. For this reason, animal behaviourists and disease ecologists have been interested in the intersection of their respective fields for decades. Despite this interest, most research at the behaviour-disease interface focuses either on how host behaviour affects parasites or how parasites affect behaviour, with little overlap between the two. Yet, the majority of interactions between hosts and parasites are probably reciprocal, such that host behaviour feeds back on parasites and vice versa. Explicitly considering these feedbacks is essential for understanding the complex connections between animal behaviour and parasite ecology and evolution. To illustrate this point, we discuss how host behaviour-parasite feedbacks might operate and explore the consequences of feedback for studies of animal behaviour and parasites. For example, ignoring the feedback of host social structure on parasite dynamics can limit the accuracy of predictions about parasite spread. Likewise, considering feedback in studies of parasites and animal personalities may provide unique insight about the maintenance of variation in personality types. Finally, applying the feedback concept to links between host behaviour and beneficial, rather than pathogenic, microbes may shed new light on transitions between mutualism and parasitism. More generally, accounting for host behaviour-parasite feedbacks can help identify critical gaps in our understanding of how key host behaviours and parasite traits evolve and are maintained.

“…Water quality was maintained through an undergravel filtration system. Fish were allowed to acclimate for two days in the compartments, and then individual temperament was assessed using the same set-up adopted in our previous experiments [11,15,21,25,28,29]. An experimental tank (70 Â 30 Â 30 cm) was divided lengthwise into two long lanes with an opaque plastic partition (figure 1).…”

“…From the tracking, we determined the time fish spent in each area ('safe' versus 'risky'), and estimated individual temperament as the proportion of time spent in the 'risky' area. This measure is known to be highly repeatable in this species [15], and we have used this measure in our previous works [11,15,21,25,28,29].…”

In many animal groups, coordinated activity is facilitated by the emergence of leaders and followers. Although the identity of leaders is to some extent predictable, most groups experience frequent changes of leadership. How do group members cope with such changes in their social role? Here, we compared the foraging behaviour of pairs of stickleback fish after a period of either (i) role reinforcement, which involved rewarding the shyer follower for following, and the bolder leader for leading, or (ii) role reversal, which involved rewarding the shyer follower for leading, and the bolder leader for following. We found that, irrespective of an individual's temperament, its tendency to follow is malleable, whereas the tendency to initiate collective movement is much more resistant to change. As a consequence of this lack of flexibility in initiative, greater temperamental differences within a pair led to improved performance when typical roles were reinforced, but to impaired performance when typical roles were reversed.
