  1. Cheetahs discriminate familiar and unfamiliar human voices

    Full-text: Available

    | Contributor(s):: Maël Leroux, Robyn Shelia Hetem, Martine Hausberger, Alban Lemasson

    Domestic species can make the distinction between several human sub-groups, especially between familiar and unfamiliar persons. The Domestication hypothesis assumes that such advanced cognitive skills were driven by domestication itself. However, such capacities have been shown in wild species...

  2. Fear vs. frustration - Possible factors behind canine separation related behaviour

    | Contributor(s):: Lenkei, R., Alvarez Gomez, S., Pongracz, P.

  3. Pet dog management practices among a representative sample of owners in Victoria, Australia

    | Contributor(s):: Howell, T. J., Mornement, K., Bennett, P. C.

    It is often assumed that pet dogs experience better welfare than livestock production animals because many owners consider them to be members of the family and, collectively, spend billions of dollars on them annually. However, this assumption is not based on scientific evidence, and a...

  4. Examining dog-human play: the characteristics, affect, and vocalizations of a unique interspecific interaction

    | Contributor(s):: Horowitz, A., Hecht, J.

    Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such routine: dog-human play. Dyadic interspecific play is known to be a common...

  5. Owners' direct gazes increase dogs' attention-getting behaviors

    | Contributor(s):: Ohkita, M., Nagasawa, M., Kazutaka, M., Kikusui, T.

  6. Bottlenose Dolphins' (Tursiops truncatus) Theory of Mind as Demonstrated by Responses to their Trainers' Attentional States

    | Contributor(s):: Masaki Tomonaga, Yuka Uwano

    The present study examined the ability of dolphins to follow the gestural signs presented by humantrainers in various attentional states in order to understand the social cognition of dolphins. Thehuman trainers enacted the gestural signs by orienting their bodies and heads in different...

  7. Dog growls express various contextual and affective content for human listeners

    | Contributor(s):: T Faragó, N Takács, A Miklósi, P Pongrácz

    Vocal expressions of emotions follow simple rules to encode the inner state of the caller into acoustic parameters, not just within species, but also in cross-species communication. Humans use these structural rules to attribute emotions to dog vocalizations, especially to barks, which match with...

  8. Owners' direct gazes increase dogs' attention-getting behaviors

    | Contributor(s):: Ohkita, M., Nagasawa, M., Kazutaka, M., Kikusui, T.

  9. Of Mice, Birds, and Men: The Mouse Ultrasonic Song System Has Some Features Similar to Humans and Song-Learning Birds

    | Contributor(s):: Gustavo Arriaga, Eric P. Zhou, Erich D. Jarvis

    Humans and song-learning birds communicate acoustically using learned vocalizations. The characteristic features of this social communication behavior include vocal control by forebrain motor areas, a direct cortical projection to brainstem vocal motor neurons, and dependence on auditory feedback...

  10. Reduced locomotor play behaviour of dairy calves following separation from the mother reflects their response to reduced energy intake

    | Contributor(s):: Rushen, J., Wright, R., Johnsen, J. F., Mejdell, C. M., Passille, A. M. de

    Play behaviour is an indicator of good welfare in young calves and is reduced by low energy intake and weaning off milk. There is renewed interest in keeping calves longer with the cow but separation leads to signs of distress, such as vocalizations. Providing calves with an alternative milk...

  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. Human classification of context-related vocalizations emitted by familiar and unfamiliar domestic cats: an exploratory study

    | Contributor(s):: Ellis, S. L. H., Swindell, V., Burman, O. H. P.

    Previous research has shown that human classification of context-specific domestic cat "meow" vocalizations is relatively poor, although improves with experience and/or general affinity to cats. To investigate whether such classification further improves when recipients (humans) of the...

  13. Evaluation of the sexual behavior and testosterone concentrations of Mangalarga Marchador stallions

    | Contributor(s):: Rua, M. A. S., Quirino, C. R., Bastos, R., Bartholazzi Junior, A., Santoro, P. N., Ribeiro, M. da S., Matos, L. F., Barreto, M. A. P.

    Assessing the sexual behavior of stallions is extremely important because sexual behavior is linked to reproductive efficiency. The objective of this study was to evaluate the sexual behavior, testosterone concentration and libido of Mangalarga Marchador stallions from northern Rio de Janeiro...

  14. Piglets call for maternal attention: vocal behaviour in Sus scrofa domesticus is modulated by mother's proximity

    | Contributor(s):: Iacobucci, P., Colonnello, V., D'Antuono, L., Cloutier, S., Newberry, R. C.

    Plasticity in the production of "separation distress" vocalizations, and seeking of caregivers beyond mere satisfaction of immediate physiological needs, are manifestations of attachment that we investigated in the domestic pig ( Sus scrofa domesticus). Female piglets from eight litters were...

  15. The Role of Speech Experience on Cue Trading in Parakeets

    | Contributor(s):: Daniel L.E. Carter, Alyssa D. Tronolone, Kanwal Asif, Ann Cheruvil

    Speech perception is a crucial element in the process of human vocal communication, but there are many unanswered questions about the role speech experience plays in this process. This research investigates if experience with human speech sounds will influence speech perception in budgerigars....

    | Contributor(s):: Chris Ramsay

    In this talk, Chris will give fascinating background into the world of dogs and how to keep man and man's best friend on their best behavior.With over a decade of study under his belt, Chris Ramsay, professional K9 specialist, can interpret the language of dogs – both vocal and...

  17. Social Influences on the Acquisition of Human-Based Codes in Parrots and Nonhuman Primates

    | Contributor(s):: Pepperberg, Irene Maxine, Snowdon, Charles T., Hausberger, Martine

  18. Cross-Fostered Chimpanzees Initiate Sign Interactions

    | Contributor(s):: Bodamer, Mark Douglas

  19. Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink

    | Contributor(s):: Malmkvist, J., Palme, R.

    Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal care...

  20. The effect of physical contact between dairy cows and calves during separation on their post-separation behavioural response

    | Contributor(s):: Johnsen, J. F., Ellingsen, K., Grondahl, A. M., Boe, K. E., Lidfors, L., Mejdell, C. M.

    Premature breaking of the maternal bond between a cow and her calf triggers a strong behavioural response which renders separation and weaning major welfare challenges in suckling systems. Fence-line separation and weaning allowing physical contact has been evaluated for beef cattle and is...
