    • Anti-predator behaviour of black-fronted titi monkeys (Callicebus nigrifrons) 

      Cäsar, Cristiane (University of St Andrews, 2012-06) - Thesis
      Titi monkeys have long been known for their complex vocal behaviour with numerous high- and low-pitched calls, which can be uttered singly or combined in more complex structures. However, up to date very little is known ...
    • Anti-predator behaviour of Guereza colobus monkeys (Colobus guereza) 

      Schel, Anne Marijke (University of St Andrews, 2009-06-24) - Thesis
      Black-and-white colobus monkeys are renowned for their impressive vocal behaviour, but up to date there have been only very few systematic efforts to study this. These monkeys are able to produce loud and low-pitched roars ...
    • Assessing host-virus codivergence for close relatives of Merkel cell polyomavirus infecting African great apes 

      Madinda, Nadège F.; Ehlers, Bernhard; Wertheim, Joel O.; Akoua-Koffi, Chantal; Bergl, Richard A.; Boesch, Christophe; Akonkwa, Dieudonné Boji Mungu; Eckardt, Winnie; Fruth, Barbara; Gillespie, Thomas R.; Gray, Maryke; Hohmann, Gottfried; Karhemere, Stomy; Kujirakwinja, Deo; Langergraber, Kevin; Muyembe, Jean Jacques; Nishuli, Radar; Pauly, Maude; Petrzelkova, Klara J.; Robbins, Martha M.; Todd, Angelique; Schubert, Grit; Stoinski, Tara S.; Wittig, Roman M.; Zuberbühler, Klaus; Peeters, Martine; Leendertz, Fabian H.; Calvignac-Spencer, Sébastien (2016-10) - Journal article
      It has long been hypothesized that polyomaviruses (PyV; family Polyomaviridae) codiverged with their animal hosts. In contrast, recent analyses suggested that codivergence may only marginally influence the evolution of ...
    • Attention following and nonverbal referential communication in bonobos (Pan paniscus), chimpanzees (Pan troglodytes) and orangutans (Pongo pygmaeus) 

      Madsen, Elainie Alenkær (University of St Andrews, 2011-06-22) - Thesis
      A central issue in the study of primate communication is the extent to which individuals adjust their behaviour to the attention and signals of others, and manipulate others’ attention to communicate about external events. ...
    • Automated face detection for occurrence and occupancy estimation in chimpanzees 

      Crunchant, Anne-Sophie; Egerer, Monika; Loos, Alexander; Burghardt, Tilo; Zuberbühler, Klaus; Corogenes, Katherine; Leinert, Vera; Kulik, Lars; Kühl, Hjalmar S. (2017-03) - Journal article
      Surveying endangered species is necessary to evaluate conservation effectiveness. Camera trapping and biometric computer vision are recent technological advances. They have impacted on the methods applicable to field surveys ...
    • A cognitive approach to the study of culture in wild chimpanzees (Pan troglodytes schweinfurthii) 

      Gruber, Thibaud (University of St Andrews, 2011-11-30) - Thesis
      The question of animal culture has been of interest for decades. Chimpanzees (Pan troglodytes) have played a key role in the debate of whether or not it is appropriate to use the term ‘culture’ to describe animal behaviour ...
    • Compositionality in animals and humans 

      Townsend, Simon W.; Engesser, Sabrina; Stoll, Sabine; Zuberbühler, Klaus; Bickel, Balthasar (2018-08-15) - Journal article
      A key step in understanding the evolution of human language involves unravelling the origins of language’s syntactic structure. One approach seeks to reduce the core of syntax in humans to a single principle of recursive ...
    • Coordination of joint activities and communication in wild chimpanzees (Pan troglodytes) of the Budongo Forest, Uganda 

      Mullins, Caroline (University of St Andrews, 2015) - Thesis
      Evidence from captive studies suggests that chimpanzees (Pan troglodytes) lack the motivation to complete cooperative tasks and there is little evidence for communication that coordinates their behaviour during joint ...
    • Enduring voice recognition in bonobos 

      Keenan, Sumir; Mathevon, Nicolas; Stevens, Jeroen M. G.; Guéry, Jean Pascal; Zuberbühler, Klaus; Levréro, Florence (2016-02-25) - Journal article
      Long-term social recognition is vital for species with complex social networks, where familiar individuals can encounter one another after long periods of separation. For non-human primates who live in dense forest ...
    • Exorcising Grice's ghost : an empirical approach to studying intentional communication in animals 

      Townsend, Simon W.; Koski, Sonja E.; Byrne, Richard W.; Slocombe, Katie E.; Bickel, Balthasar; Boeckle, Markus; Braga Goncalves, Ines; Burkart, Judith M.; Flower, Tom; Gaunet, Florence; Glock, Hans Johann; Gruber, Thibaud; Jansen, David A. W. A. M.; Liebal, Katja; Linke, Angelika; Miklósi, Ádám; Moore, Richard; van Schaik, Carel P.; Stoll, Sabine; Vail, Alex; Waller, Bridget M.; Wild, Markus; Zuberbühler, Klaus; Manser, Marta B. (2017-08) - Journal article
      Language's intentional nature has been highlighted as a crucial feature distinguishing it from other communication systems. Specifically, language is often thought to depend on highly structured intentional action and ...
    • Form and function of non-linguistic calls in human infants 

      Kersken, Verena (University of St Andrews, 2012-06-19) - Thesis
      Before infants speak their first word, they already produce a large variety of sounds. Whilst the developmental process that leads to speech production is very well documented, little attention is given to how non-linguistic ...
    • Formal monkey linguistics 

      Schlenker, Philippe; Chemla, Emmanuel; Schel, Anne M.; Fuller, James; Gautier, Jean-Pierre; Kuhn, Jeremy; Veselinović, Dunja; Arnold, Kate; Cäsar, Cristiane; Keenan, Sumir; Lemasson, Alban; Ouattara, Karim; Ryder, Robin; Zuberbühler, Klaus (2016-07-05) - Journal article
      We argue that rich data gathered in experimental primatology in the last 40 years can benefit from analytical methods used in contemporary linguistics. Focusing on the syntactic and especially semantic side, we suggest ...
    • Formal monkey linguistics : the debate 

      Schlenker, Philippe; Chemla, Emmanuel; Schel, Anne M.; Fuller, James; Gautier, Jean Pierre; Kuhn, Jeremy; Veselinović, Dunja; Arnold, Kate; Cäsar, Cristiane; Keenan, Sumir; Lemasson, Alban; Ouattara, Karim; Ryder, Robin; Zuberbühler, Klaus (2016-07-05) - Journal article
      We explain why general techniques from formal linguistics can and should be applied to the analysis of monkey communication - in the areas of syntax and especially semantics. An informed look at our recent proposals shows ...
    • Identity information in bonobo vocal communication: from sender to receiver 

      Keenan, Sumir (University of St Andrews, 2017-06-01) - Thesis
      Identity information is vital for highly social species as it facilitates individual recognition and allows for differentiation between social partners in many contexts, such as dominance hierarchies, territorial defence, ...
    • Impact of snare injuries on parasite prevalence in wild chimpanzees (Pan troglodytes) 

      Yersin, Harmony; Asiimwe, Caroline; Voordouw, Maarten J.; Zuberbühler, Klaus (2017-02) - Journal article
      Many primate populations are severely threatened by human activity. Illegal hunting with snares frequently causes fatal injuries and permanent mutilations in wild primates. Traumatic injuries and stressful experiences can ...
    • Intra-sexual competition and vocal counter-strategies in wild female chimpanzees (Pan troglodytes schweinfurthii) 

      Townsend, Simon W. (University of St Andrews, 2009) - Thesis
      A growing body of behavioural data is beginning to show that, like their male counterparts, female chimpanzees can be competitive and aggressive, particularly when resources come under pressure. These observations are ...
    • Kin-based cultural transmission of tool use in wild chimpanzees 

      Lamon, Noemie; Neumann, Christof; Gruber, Thibaud; Zuberbühler, Klaus (2017-04-26) - Journal article
      Current research on animal culture has focused strongly on cataloging the diversity of socially transmitted behaviors and on the social learning mechanisms that sustain their spread. Comparably less is known about the ...
    • Listeners can extract meaning from non-linguistic infant vocalisations cross-culturally 

      Kersken, Verena; Zuberbühler, Klaus; Gomez, Juan-Carlos (2017-01-25) - Journal article
      We present empirical evidence showing that the acoustic properties of non-linguistic vocalisations produced by human infants in different cultures can be used cross-culturally by listeners to make inferences about the ...
    • Morphologically structured vocalizations in female Diana monkeys 

      Coye, Camille; Zuberbühler, Klaus; Lemasson, Alban (2016-05) - Journal article
      Social complexity is often thought of as a driving force in the evolution of communication and cognition, but this is at odds with the fact that nonhuman primates generally display only very limited flexibility in vocal ...
    • Pant-grunts in wild chimpanzees (Pan troglodytes schweinfurthii): the vocal development of a social signal 

      Laporte, Marion N.C. (University of St Andrews, 2011-06-21) - Thesis
      While the gestural communication of apes is widely recognised as intentional and flexible, their vocal communication still remains considered as mostly genetically determined and emotionally bound. Trying to limit the ...
