  1. 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...

  2. 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...

  3. 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...

  4. 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;...

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

    Full-text: Available

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

  6. 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.

  7. 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,...

  8. 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...

  9. 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...

  10. Deer-activated bioacoustic frightening device deters white-tailed deer

    | Contributor(s):: Hildreth, Aaron M., Hygnstrom, Scott E., VerCauteren, Kurt C.

  11. Improved methods for deterring cliff swallow nesting on highway structures

    | Contributor(s):: Delwiche, M. J., Coates, R. W., Gorenzel, W. P., Salmon, T. P.

  12. A Comparative Study of Human and Parrot Phonation: Acoustic and Articulatory Correlates of Vowels

    | Contributor(s):: Patterson, D. K., Pepperberg, I. M.

  13. Vowel Discrimination in Cats: Acquisition, Effects of Stimulus Level, and Performance in Noise

    | Contributor(s):: Hienz, Robert D., Aleszczyk, Cynthia M., May, Bradford J.

  14. Vowel Discrimination in Cats: Thresholds for the Detection of Second Formant Changes in the Vowel /(epsilon)

    | Contributor(s):: Hienz, Robert D., Aleszczyk, Cynthia M., May, Bradford J.

  15. Bioacoustic monitoring of aggression in group-housed rhesus macaques

    | Contributor(s):: McCowan, B., Rommeck, I.

    Many captive primate facilities house rhesus macaques in multimale-multifemale social groups in large enclosures that simulate the natural social and environmental features characteristic of the species, enhancing their reproductive performance as well as their psychological well-being, yet one...

  16. Acoustic communication in the domestic horse (Equus caballus)

    | Contributor(s):: Yeon, Seong C.

  17. Responses of human-habituated wild Atlantic spotted dolphins to play behaviors using a two-way human/dolphin interface

    | Contributor(s):: Herzing, Denise L., Delfour, Fabienne, Pack, Adam A.
