DESCRIPTION:Sleep is vital for health and fitness\, and its expression is s
 haped by ecological and social contexts that may either promote or disturb
  it. Most research\, however\, has focused on captive settings\, detached 
 from natural environments that can modify the balance between benefits and
  drawbacks of sleeping in a group. Using direct recording of sleep using a
  custom-made\, infrared remote camera\, mounted on a telescopic pole s\, w
 e examined the impact of social rank and context on sleep in wild chimpanz
 ees in Uganda. High-ranking males experienced shorter\, more fragmented an
 d less efficient sleep than subordinates. Party composition also influence
 d sleep: whereas sleeping in groups generally prolonged sleep duration and
  reduced wake-bout durations compared to sleeping alone\, increasing the n
 umber of adult males in the sleeping party delayed nesting time and reduce
 d sleep duration in high-ranking individuals. The presence of sexually act
 ive females delayed nesting time and advanced waking time in males\, tende
 d to reduce sleep duration and increased sleep fragmentation. These findin
 gs emphasize the need to study sleep in ecological contexts to gain a deep
 er understanding of the trade-offs shaped by social dynamics in sleep patt
 erns.\nSpeaker: Clara Hozer
