DESCRIPTION: There are both costs and benefits to group living. Benefits in
 clude reduced predation risk\, while costs involve increased competition a
 mong group members for resources. Some social groups manage these trade-of
 fs through fission-fusion dynamics\, where groups regularly split into sub
 groups (fission) and later merge back together (fusion). Understanding the
  factors that drive these events and the mechanisms group members use to n
 avigate these processes can provide insights into the proximate and ultima
 te drivers of group living. In this thesis\, I use white-nosed coatis as a
  study system to investigate the extent and nature of their fission-fusion
  dynamics and the role of vocal signalling during these processes. By leve
 raging advanced tracking technologies\, I simultaneously recorded the loca
 tions and vocalisations of all members of three wild white-nosed coati gro
 ups in Soberania National Park and on Barro Colorado Island\, Panama. Util
 ising these data\, I characterise the extent of white-nosed coati fission-
 fusion dynamics and investigate the role of social and demographic factors
  in shaping their subgrouping behaviours. I found that individuals have co
 nsistent social preferences when deciding whom to split with\, and these p
 references are driven by relatedness rather than demographic factors such 
 as age and sex. I characterise different fission and fusion types\, provid
 ing a framework for investigating these processes that can be applied acro
 ss diverse social and ecological contexts. I show that coatis use vocalisa
 tions to coordinate fission and fusion events and suggest that these event
 s are driven by varying preferences for when to travel and foraging compet
 ition. These results offer new insights into the factors that shape decisi
 on-making processes\, shedding light on the drivers of group living.\nSpea
