    | Contributor(s):: Ma, Meina, Hua, Rui, Bao, Darhan, Ye, Guohui, Tang, Zhuangsheng, Hua, Limin

    Acoustic communication plays a vital role in passing or sharing information between individuals. Identifying the biological meaning of vocal signals is crucial in understanding the survival strategies of animals. However, there are many challenges in identifying the true meaning of such...

  4. There You Are! Automated Detection of Indris’ Songs on Features Extracted from Passive Acoustic Recordings

    Full-text: Available

    | Contributor(s):: Ravaglia, Davide, Ferrario, Valeria, De Gregorio, Chiara, Carugati, Filippo, Raimondi, Teresa, Cristiano, Walter, Torti, Valeria, Hardenberg, Achaz Von, Ratsimbazafy, Jonah, Valente, Daria, Giacoma, Cristina, Gamba, Marco

    The growing concern for the ongoing biodiversity loss drives researchers towards practical and large-scale automated systems to monitor wild animal populations. Primates, with most species threatened by extinction, face substantial risks. We focused on the vocal activity of the indri (Indri...

  5. Vocal expression of emotions in farmed spotted paca (Cuniculus paca)

    | Contributor(s):: Lima, Allison F., Lima, Stella G. C., Nogueira-Filho, Sérgio L. G., Held, Suzanne, Paul, Elizabeth, Mendl, Michael, Nogueira, Selene S. C.

  6. Music for animal welfare: A critical review & conceptual framework

    | Contributor(s):: Kriengwatana, Buddhamas P., Mott, Richard, ten Cate, Carel

    Music can have powerful effects on human health and wellbeing. These findings have inspired an emerging field of research that focuses on the potential of music for animal welfare, with most studies investigating whether music can enhance overall wellbeing. However, this sole focus on discovering...

  7. Acoustic variables of high-pitched vocalizations in dairy sheep breeds

    | Contributor(s):: Papadaki, Kallirroi, Laliotis, George P., Bizelis, Iosif

    The source–filter theory of voice production is widely used on mammal vocal communication research allowing a better understanding of individual and context variations. Generally, mammals with less complex repertoires have received little attention regarding the influence of different...

  8. Automatic Classification of Cat Vocalizations Emitted in Different Contexts

    Full-text: Available

    | Contributor(s):: Stavros Ntalampiras, Luca Andrea Ludovico, Giorgio Presti, Emanuela Prato Previde, Monica Battini, Simona Cannas, Clara Palestrini, Silvana Mattiello

    Cats employ vocalizations for communicating information, thus their sounds can carry a wide range of meanings. Concerning vocalization, an aspect of increasing relevance directly connected with the welfare of such animals is its emotional interpretation and the recognition of the production...

  9. Effective and accurate discrimination of individual dairy cattle through acoustic sensing

    | Contributor(s):: Yajuvendra, Singh, Lathwal, Surender S., Rajput, Nitendra, Raja, Thiruvothur V., Gupta, Ashok K., Mohanty, Tushar K., Ruhil, Anand P., Chakravarty, Atish K., Sharma, Prakash C., Sharma, Vijay, Chandra, Gulab

    Acoustic sensing seems to be one of the best methods for monitoring of dairy animals at an organized farm for their better care and management. The main aim of present investigation was to establish the existence of significant differences for various acoustic features of vocal signals uttered...

  10. Indicators of age, body size and sex in goat kid calls revealed using the source–filter theory

    | Contributor(s):: Briefer, Elodie, McElligott, Alan G.

    The source–filter theory is an important framework recently applied to the study of animal vocalisations, which links the mode of vocal production to call parameters. Vocalisations can be good indicators of a sender's characteristics, such as identity, body size, age, and even hormonal status and...

  11. Comparison of methods to quantify the number of bites in calves grazing winter oats with different sward heights

    | Contributor(s):: Nadin, Laura B., Chopa, Federico Sánchez, Gibb, Malcolm J., Trindade, Júlio Kuhn da, Amaral, Glaucia Azevedo do, de Faccio Carvalho, Paulo C., Gonda, Horacio L.

    The requirement to measure the constituents of ingestive behaviour in grazing ruminants, such as the number and type of jaw movements, is essential for understanding the herbage intake process. In this experiment, three methods of recording grazing behaviour were compared: visual observation (VO;...

  12. Cross-modal perception of human emotion in domestic horses (Equus caballus)

    Full-text: Available

    | Contributor(s):: Nakamura, K., Takimoto-Inose, A., Hasegawa, T.

    Humans have domesticated many kinds of animals in their history. Dogs and horses have particularly close relationships with humans as cooperative partners. However, fewer scientific studies have been conducted on cognition in horses compared to dogs. Studies have shown that horses cross-modally...

  13. The Impact of Equine Therapy and an Audio-Visual Approach Emphasizing Rhythm and Beat Perception in Children with Developmental Coordination Disorder

    | Contributor(s):: Hession, C. E., Law Smith, M. J., Watterson, D., Oxley, N., Murphy, B. A.

  14. An unexpected acoustic indicator of positive emotions in horses

    Full-text: Available

    | Contributor(s):: Mathilde Stomp, Maël Leroux, Marjorie Cellier, Séverine Henry, Alban Lemasson, Martine Hausberger

    Indicators of positive emotions are still scarce and many proposed behavioural markers have proven ambiguous. Studies established a link between acoustic signals and emitter’s internal state, but few related to positive emotions and still fewer considered non-vocal sounds. One of them,...

  15. Domestic dogs' understanding of human emotional cues

    | Contributor(s):: Min Hooi Yong

    Past research has focused on the ability of domestic dogs to recognise human communicative cues such as human pointing, eye gaze, attachment behaviour, social learning, and responses to affective stimuli. However, there is still much to be learned about dogs’ ability to recognise human...

  16. Hemodynamic (fNIRS) and EEG (N200) correlates of emotional inter-species interactions modulated by visual and auditory stimulation

    Full-text: Available

    | Contributor(s):: Balconi, M., Vanutelli, M. E.

    The brain activity, considered in its hemodynamic (optical imaging: functional Near-Infrared Spectroscopy, fNIRS) and electrophysiological components (event-related potentials, ERPs, N200) was monitored when subjects observed (visual stimulation, V) or observed and heard...
