    • Context-specific close-range "hoo" calls in wild gibbons (Hylobates lar) 

      Clarke, Esther; Reichard, Ulrich H.; Zuberbuehler, Klaus (2015-04-08) - Journal article
      Background: Close range calls are produced by many animals during intra-specific interactions, such as during home range defence, playing, begging for food, and directing others. In this study, we investigated the most ...
    • The evolutionary roots of creativity : mechanisms and motivations 

      Wiggins, Geraint A.; Tyack, Peter Lloyd; Scharff, Constance; Rohrmeier, Martin (2015-03) - Journal article
      We consider the evolution of cognition and the emergence of creative behaviour, in relation to vocal communication. We address two key questions: (i) what cognitive and/or social mechanisms have evolved that afford aspects ...
    • Food-offering calls in wild golden lion tamarins (Leontopithecus rosalia) : evidence for teaching behavior? 

      Troisi, Camille Aurelie; Hoppitt, Will J.; Ruiz-Miranda, Carlos R.; Laland, Kevin Neville (2018-11-21) - Journal article
      Many animals emit calls in the presence of food, but researchers do not always know the function of these calls. Evidence suggests that adult golden lion tamarins (Leontopithecus rosalia) use food-offering calls to teach ...
    • Vervet monkeys greet adult males during high-risk situations 

      Mercier, Stéphanie; Neumann, Christof; van de Waal, Erica; Chollet, Emmeline; de Bellefon, Jade Meric; Zuberbuhler, Klaus (2017-10) - Journal article
      Many animal species produce ritualized signals during dyadic encounters but the functions of such ‘greeting’ behaviour vary considerably, or are often unknown. One established function is to acknowledge existing dominance ...
    • Vocal communication in bonobos (Pan paniscus) : studies in the contexts of feeding and sex 

      Clay, Zanna (University of St Andrews, 2011-06) - Thesis
      Despite having being discovered nearly 80 years ago, bonobos (Pan paniscus) are still one of the least well understood of the great apes, largely remaining in the shadow of their better known cousins, the chimpanzees (Pan ...
    • Vocal correlates of individual sooty mangabey travel speed and direction 

      Neumann, Christof; Zuberbühler, Klaus (2016-07-28) - Journal article
      Many group-living animals coordinate movements with acoustic signals, but so far most studies have focused on how group movements are initiated. In this study, we investigated movement patterns of wild sooty mangabeys ...
