SUMMARY:Social structure\, collective decision-making and responses to the
  rise of inequality in animal societies - Danai Papageorgiou (University o

DESCRIPTION:Animals living in stable and cohesive groups acquire critical 
 resources for survival while moving together. These groups can vary in siz
 e and composition\, facing challenges induced by environmental heterogenei
 ty. To shed light on the effects of the social and physical environment on
  collective behavior\, I studied groups of vulturine guineafowl (Acryllium
  vulturinum) in the Kenyan savannah using high-resolution GPS tracking\, f
 ield observations\, video tracking\, and environmental data. My collaborat
 ive work demonstrates that vulturine guineafowl\, as well as other bird sp
 ecies\, can form multilevel societies where stable groups associate prefer
 entially\, forming super-groups. Inter-group associations in turn are shap
 ed by habitat features and seasonality. Guineafowl groups of intermediate 
 size exhibit optimal ranging behavior and higher reproductive success. Ext
 reme environmental conditions\, such as droughts\, significantly expand th
 e areas used by the groups. Despite changing environments\, guineafowl mai
 ntain cohesion through shared decision-making\, ensuring that group member
 s satisfy their needs\, even during conflicts over food. Collective respon
 ses to emerging inequality during such conflicts play a crucial role in ma
 intaining the benefits of group-living across species. Overall\, this stud
 y highlights the shaping of outcomes and dynamics of collective behavior i
 n wild group-living animals through the interaction between the social and
  physical environment.
