Social defeat is a powerful experience leading to drastic changes in physiology and behavior, many of which are negative. For example, repeated social vertebrates results reduced reproductive success, sickness behavioral abnormalities that threaten individual survival species persistence. However, little known about what neural mechanisms involved determining whether an resilient or susceptible stress. It also remains unknown exclusive use reactive behaviors after maintained over time impacts future during subsequent contests. We used resident-intruder experiment the African cichlid fish Astatotilapia burtoni investigate behavior correlates these two opposing groups. Behavior was quantified by watching trials distinguish individuals. Both started with searching freezing behaviors, decreasing increasing defeat. After 4 day break period, both encounter new resident, while almost exclusively behaviors. By quantifying activation using pS6 socially relevant brain regions, we identified differential patterns associated found nuclei co-varied may represent functional networks. These data provide first evidence specific conserved networks underlying stress resilience susceptibility fishes.

Evolution towards complex forms of sociality is dependent on overcoming conflicts interest between prospective social partners. Competition for limited resources a key aspect such conflicts. Behaviour that results in conflict resolution without termination the relationship thus predicted to be more prevalent species. We here tested this hypothesis by staging contests conspecifics over crucial resource, using three lamprologine cichlid species differ their sociality. The cooperatively breeding (Neolamprologus pulcher) indeed demonstrated improved resolution, showing egalitarian sharing resource and establishing mutually tolerant relationships often compared pair-bonded (Variabilichormis moorii) mostly solitary (Lepidiolamprologus elongatus). suggest result behavioural differences these cichlids: N. pulcher already showed de-escalating behaviour during earliest stages increased rates behaviours response heightened levels aggression.

Abstract A key challenge in animal behavior is disentangling the social stimuli that drive conspecific behaviors. For behaviors like birdsong, insights can be made through experimental isolation of relevant cues affect behavior. However, for some species teleost fish, putative sexual signaling are inextricably linked to others, making it difficult parse precise roles distinct signals play driving In African cichlid Astatotilapia burtoni , males dominant or subordinate, wherein bright coloration and territorial courtship correlate positively with rank. Here, we leveraged androgen receptor (AR) mutant male A. lack dominance-typical but not isolate role female mating this species. We found independent behavioral assays females behave aggressively towards AR WT still mated both types males.
