“…

Previous formulations (McNamara & Houston 2002) considered the unrealistic case where P2 always cooperated or always defected. Typically, however, heritable behavioural traits are continuously distributed within populations (Dall et al 2004; Dingemanse et al 2004; van Oers et al 2005; Blumstein et al 2006; Penke et al 2007). To reflect this, we model an individual's heritable (unconditional) tendency to cooperate in role P2 as specified by p (0≤ p ≤1), where p is the probability of cooperating.

To highlight the importance of social awareness, P1 individuals have the option of obtaining information on P2s at a cost.

Evolution of trust and trustworthiness: social awareness favours personality differences

Interest in the evolution and maintenance of personality is burgeoning. Individuals of diverse animal species differ in their aggressiveness, fearfulness, sociability and activity. Strong trade-offs, mutation–selection balance, spatio-temporal fluctuations in selection, frequency dependence and good-genes mate choice are invoked to explain heritable personality variation, yet for continuous behavioural traits, it remains unclear which selective force is likely to maintain distinct polymorphisms. Using a model of trust and cooperation, we show how allowing individuals to monitor each other's cooperative tendencies, at a cost, can select for heritable polymorphisms in trustworthiness. This variation, in turn, favours costly ‘social awareness’ in some individuals. Feedback of this sort can explain the individual differences in trust and trustworthiness so often documented by economists in experimental public goods games across a range of cultures. Our work adds to growing evidence that evolutionary game theorists can no longer afford to ignore the importance of real world inter-individual variation in their models.

“…Haage et al (2013) sugges ted that captive European mink exhibit different 'personalities' (sensu Gosling 2001). Individual personality types may differ in their exploratory or dispersal behaviour (Dingemanse et al 2003) and/or in their response to predators (Blumstein et al 2006); therefore, this phenomenon may be worth further consideration in future reintroductions.…”

N aïve captive-bred animals often make excessive movements when released into the wild, which may increase vulnerability to predation, take animals into unsuitable habitat and/or increase the probability of conflict with humans. We analysed the post-release movements of captive-bred European mink Mustela lutreola reintroduced to Hiiumaa Island, Estonia. We tested the effect of pre-release enclosure type, sex, generations in captivity, pregnancy and age on post-release movements, investigated the settlement process and explored the relationship between post-release movements and survival. We found no effect of enclosures on post-release movements in the first 2 wk following release (except that individuals from large naturalistic enclosures spent less time close to water than did animals from standard zoo enclosures) but some evidence of a slight effect at 1 mo post-release. Males moved further at 3 d (but not 2 wk) postrelease than did females, and juveniles appeared to move further in the first 3 d post-release than did 1 yr olds. We were unable to detect a relationship between post-release movements and survival. The largest known cause of mortality was predation, but it was not clear why mink were vulnerable to predation, and the locational data presented here were unable to shed light on this issue. Individual variation also made it difficult to define patterns. These are common problems in reintroductions, and we suggest that in future releases of captive-bred animals, more detailed post-release behavioural observations and investigation of personality types might be insightful.

“…Information on the extent to which specific behaviours are learnt is valuable in conservation, particularly for practices involving captive rearing (Griffin, 2004). Captive‐rearing programmes with objectives to re‐establish wild populations should aim to maintain a high level of natural function, including behavioural repertoires, in target species (Sutherland, 1998; Singh & Kaumanns, 2005; Blumstein, Holland & Daniel, 2006). For example, the retention and possession of predator–response behaviours, as well as abilities to recognize conspecifics and their alarm vocalizations, are critical for successful re‐introduction to the wild (Hákansson & Jensen, 2005).…”

Consequently, it is valuable to determine the influence of experience and learning in general and social learning in particular, on such fitness‐relevant behaviours (Blumstein et al , 2006). The benefit of this information is to be able to make informed management decisions regarding how to minimize developmental interference and the loss of species‐specific behavioural traits and traditions (Sutherland, 1998).…”

Alarm responses are maintained during captive rearing in chicks of endangered kaki

The maintenance of species-specific behavioural repertoires and traditions is an important but often implicit goal of conservation efforts. When captive rearing is used as a conservation practice, it becomes critical to address its possible implications for the social and behavioural traits of developing individuals. In particular, animals must retain or acquire many of their behavioural abilities to increase the likelihood of survival upon release into the wild. This study investigated the behavioural development of critically endangered kaki (black stilt: Himantopus novaezelandiae) chicks reared without live adult conspecifics. The captive rearing programme included playbacks of adult kaki alarm calls during cleaning and handling of precocial chicks housed as groups. We used videotaped observations and playback experiments to address the following questions: do kaki chicks respond differentially to (1) familiar versus unfamiliar adult kaki alarm calls and (2) conspecific alarm versus heterospecific control vocalizations. Adultnaı¨ve kaki chicks exhibited a varied behavioural repertoire over their early development. In multivariate analyses, when age was statistically controlled, chicks showed responses to familiar and unfamiliar alarm calls that were similar in magnitude. In contrast, following conspecific alarm calls chicks had longer average latencies to resume pre-playback activities than following heterospecific vocalizations. Although the generality of these conclusions is limited by experimental constraints stemming from working with an endangered species, the findings suggest that current management techniques produce captive-reared kaki for release into the wild that possess many of the behavioural and auditory recognition skills that are required for survival.
