Genetically based social communication in an inbred group-living wild mammal
… organs to communicate both within and between groups, as well as intra- and intersexually. Their exceptional breeding system, cooperative behavior and inbreeding levels make them the ideal target for investigating the effects of the MHC on fitness and its potential involvement in chemical …

Group living features can challenge predictions for the evolution of altruistic behaviors
… behaviors is also characterized by various group living features, including group structure and social interactions. In this thesis, I develop models to study how the specificities of group living can influence the evolution of altruistic behaviors. I use inclusive fitness models to …

Habitat-specific fitness benefits of sociality in Octodon degus
… focused on how ecology shapes the evolution of group-living and cooperation in social vertebrates. Evidence suggests that group-living and cooperation enhance reproductive success under harsh local conditions in some species. Across two years, I studied two populations of Octodon degus, a …

Does personality affect competition, social organization, and fitness? a study using a small social mammal, Octodon degus
… can play a large role in the interactions among group-living animals. I studied the common degu (Octodon degus), a social and group-living rodent, to evaluate whether three personality traits (aggression, boldness, and activity level) play a role in shaping competitive interactions and …

The socio-ecology and social behaviour of the brown hyaena Hyaena Brunnea, Thunberg, 1820 in the southern Kalahari.
… foragers, but most of them live in small groups which inhabit large territories. The rest of the population consists of dispersing subadults and nomadic adult males. Territory size is mainly affected by the dispersion pattern of the food in the territory and group size by the "quality" of …

The individual and collective behavior of social organisms across environments
… diversity can drive behavioral variation. For group-living organisms, this variation is present at both the individual and the collective levels, with individual behavioral phenotypes and interactions among individuals driving collective behavior. However, gaps remain in our understanding of …

Infectious disease as a cause and consequence of phenotypic responses to challenge in a songbird species
… birds, choosing to spend more time with a group of conspecifics than alone. Because this increased social preference was no longer present once birds recovered, this phenotypic change in sociality may have specific benefits for actively infected birds. Finally, my last experiment expands …

Testing the Dual Evolutionary Foundations of Political Ideology Using Incentivised Behavioural Tasks
… from two key shifts in the evolution of human group living. First, humans began to cooperate more across wider interdependent networks and share the spoils of cooperation more evenly. Second, humans became more committed to group viability, conforming to social norms in culturally marked groups …

Behavioural ecology of the Redbilled Woodhoopoe Phoeniculus purpureus in South Africa
… were to investigate (1) why woodhoopoes live in groups; (2) why nonbreeders do not breed; and, (3) why nonbreeders provision young that are not their own? Ecological and demographic data were gathered in addition to detailed behavioural observations of 54 woodhoopoe flocks. The following …

Accounting for intraspecific variation transforms our understanding of artiodactyl social evolution
… organization (84%) rather than solitary or group-living. A clear ancestral mating system for Artiodactyla, however, could not be resolved. These results show that intraspecific variation is common in artiodactyls and perissodactyls, and suggest a variable ancestral social organization for …

Mechanisms involved in eusocial evolution in bees
