“…Individuals that provided more parental care (food provisioning) were also more exploratory and less aggressive (Budaev et al, 1999). Other studies have also reported evidence of a trade-off between parental behavior and aggression.…”

“…For example, Budaev et al (1999) found that parental convict cichlids differed in how they behaved toward their offspring, and those differences were correlated with behavior in other contexts. Individuals that provided more parental care (food provisioning) were also more exploratory and less aggressive (Budaev et al, 1999).…”

“…The causal relationships between these factors remain to be determined. Personality characteristics have been described in the convict cichlid and appear to have important consequences for parental behaviour (Budaev et al 1999). Females and males usually assume different roles in the parental care process but these roles are somewhat variable (Itzkowitz et al 2005), and some animals adhere to their sex role more tightly than others.…”

Aggression, sex and individual differences in cerebral lateralization in a cichlid fish

Cerebral lateralization is an evolutionarily ancient adaptation, apparently ubiquitous among vertebrates. Despite demonstrated advantages of having a more lateralized brain, substantial variability in the strength of lateralization exists within most species. The underlying reasons for the maintenance of this variation are largely unknown. Here, we present evidence that the strength of lateralization is linked to a behavioural trait, aggressiveness, in the convict cichlid ( Archocentrus nigrofasciatus ), and that this relationship depends on the sex of the fish. This finding suggests that individual variation in behaviour may be linked to variation in cerebral lateralization, and must be studied with regard to the sex of the animal.

“…Cronbach's 183 alpha, an internal consistency statistic that has previously been used to assess the stability of 184 animal behaviour types (e.g. Budaev 1997; Budaev et al 1999), was high for our measures 185 9 for three days following day 9. We did not find evidence that birds altered dominance 188 throughout the experiment.…”

34There is an increasing understanding of the context-dependent nature of parasite 35 virulence. Variation in parasite virulence can occur when infected individuals compete with 36 conspecifics that vary in infection status; virulence may be higher when competing with 37 uninfected competitors. In vertebrates with social hierarchies, we propose that these 38 competition-mediated costs of infection may also vary with social status. Dominant 39 individuals have greater competitive ability than competing subordinates, and consequently 40 may pay a lower prevalence-mediated cost of infection. In this study we investigated whether 41 costs of malarial infection were affected by the occurrence of the parasite in competitors and 42 social status in domestic canaries (Serinus canaria). We predicted that infected subordinates 43 competing with non-infected dominants would pay higher costs than infected subordinates 44 competing with infected dominants. We also predicted that these occurrence-mediated costs 45 of infection would be ameliorated in infected dominant birds. We found that social status and 46 the occurrence of parasites in competitors significantly interacted to change haematocrit in 47 infected birds. Namely, subordinate and dominant infected birds differed in haematocrit 48 depending on the infection status of their competitors. However, in contrast to our prediction 49 dominants fared better with infected subordinates, whereas subordinates fared better with 50 uninfected dominants. Moreover, we found additional effects of parasite occurrence on 51 mortality in canaries. Ultimately, we provide evidence for costs of parasitism mediated by 52 social rank and the occurrence of parasites in competitors in a vertebrate species. This has 53 important implications for our understanding of the evolutionary processes that shape parasite 54 virulence and group living. 55
