One- and Two-Month-Old Dog Puppies Exhibit Behavioural Synchronization with Humans Independently of Familiarity
| Contributor(s):: Duranton, Charlotte, Courby-Betremieux, Cécile, Gaunet, Florence
Behavioural synchronization is a widespread skill in social species as it helps increase group cohesion among individuals. Such a phenomenon is involved in social interactions between conspecifics as well as between individuals from different species. Most importantly, familiarity and...

Play Behavior in Two Captive Bottlenose Dolphin Calves (Tursiops Truncatus): Ethogram, Ontogeny, and Individual Differences
| Contributor(s):: Soriano Jimenez, Ana Isabel, Drago, Massimiliano, Vinyoles, Dolors, Maté, Carmen
This research focused on different aspects of play behavior including ethogram, ontogeny, and individual differences, in one male and one female captive bottlenose dolphin calves (Tursiops truncatus) from November 2003 to June 2004. We presented the first peer-reviewed description of a play...

Loss of light colour preference after chronic embryonic stress in rainbow trout fry: A novel and potential indicator of fish welfare?
| Contributor(s):: Colson, Violaine, Ferreira, Vitor Hugo Bessa, Luchiari, Ana Carolina, Valotaire, Claudiane, Borel, Frédéric, Bugeon, Jérôme, Prigent, Sylvain, Dickel, Ludovic, Calandreau, Ludovic, Guesdon, Vanessa
For many fish species, environmental colour may act either as a source of stress or as a stress-buffer, alleviating behavioural and physiological responses after a stressful situation. While much is known on the effects of environmental colour on fish stress parameters, knowledge on the effects...

Development and consistency of fearfulness in horses from foal to adult
| Contributor(s):: Christensen, Janne Winther, Beblein, Carina, Malmkvist, Jens
Understanding the development and consistency of behavioural responses across life stages is of both fundamental and applied interest. In horses, fearfulness is particularly important because fear reactions are a major cause of human-horse accidents, and because fear is a negative emotional state...

The role of genes, epigenetics and ontogeny in behavioural development
| Contributor(s):: Rodenburg, T. Bas
This review focuses on the role of genes, epigenetics and ontogeny in behavioural development of animals. The behavioural characteristics of an individual are determined by its genes and by its physical and social environment. Not only the individual's early life and current environment are of...

Chewable materials before weaning reduce tail biting in growing pigs
| Contributor(s):: Telkänranta, Helena, Swan, Kirsi, Hirvonen, Heikki, Valros, Anna
Tail biting in pigs is a multi-factorial problem, and the early rearing environment has been proposed as a potential previously unidentified factor. The aim of this study was to test whether access to chewable material from birth to weaning reduces later tail biting. Undocked litters of 59 sows...

Can sow pre-lying communication or good piglet condition prevent piglets from getting crushed?
| Contributor(s):: Melišová, Michala, Illmann, Gudrun, Andersen, Inger Lise, Vasdal, Guro, Haman, Jiří
This study focused on the impact of sow–piglet communication during pre-lying behaviour and piglet condition on piglet location before the sow was lying down and on the incidence of piglet crushing. Eighteen loose-housed, Yorkshire×Norwegian Landrace sows and their litters were studied on Day 1...

Individual and group level trajectories of behavioural development in Border collies
| Contributor(s):: Riemer, Stefanie, Müller, Corsin, Virányi, Zsófia, Huber, Ludwig, Range, Friederike
In order to assess dogs’ personality changes during ontogeny, a cohort of 69 Border collies was followed up from six to 18–24 months. When the dogs were 6, 12, and 18–24 months old, their owners repeatedly filled in a dog personality questionnaire (DPQ), which yielded five personality factors...

A Tinbergian review of self-injurious behaviors in laboratory rhesus macaques
| Contributor(s):: Polanco, Andrea
Self-injurious behaviors (SIBs) are a welfare and practical concern in laboratory rhesus macaques (Macaca mulatta), and may share a similar etiology to human SIBs. This review uses a Tinbergian perspective to investigate why rhesus monkeys perform SIBs. In addition to reviewing research...

Behaviour of gilts before and at parturition after intensified human-animal contact, training to be driven, or exposure to a farrowing pen
| Contributor(s):: Brötje, Anska, Gygax, Lorenz, Hillmann, Edna, Wechsler, Beat
During rearing and until first insemination, housing conditions of gilts are relatively constant and the few human-animal interactions negative. Around first parturition, however, gilts experience intensified contact with stockpersons and are subjected to new management procedures such as being...

Human-directed behaviour in goats is not affected by short-term positive handling
| Contributor(s):: Jan Langbein, Annika Krause, Christian Nawroth
In addition to domestication, interactions with humans or task-specific training during ontogeny have been proposed to play a key role in explaining differences in human–animal communication across species. In livestock, even short-term positive interactions with caretakers or other...

Association between personality and stereotypic behaviours in the African striped mouse Rhabdomys dilectus
| Contributor(s):: Joshi, Sneha, Pillay, Neville
Stereotypic behaviours, which are abnormal, repetitive and invariant behaviours caused by frustration and/or central nervous system dysfunction, develop as a result of sub-optimal captive conditions that provide inadequate motor and sensory stimulation. However, not all individuals housed under...

Individual hunting behaviour and prey specialisation in the house cat Felis catus: implications for conservation and management
| Contributor(s):: Dickman, C. R., Newsome, T. M.
Predators are often classed as prey specialists if they eat a narrow range of prey types, or as generalists if they hunt multiple prey types. Yet, individual predators often exhibit sex, size, age or personality-related differences in their diets that may alter the impacts of predation on...

Dietary fatty acid composition significantly influenced the proactive-reactive behaviour of Senegalese sole ( Solea senegalensis) post-larvae
| Contributor(s):: Ibarra-Zatarain, Z., Morais, S., Bonacic, K., Campoverde, C., Duncan, N.
Few studies have examined the influence of diet on larval proactive-reactive behavioural dimension of stress coping style responses. The present study evaluated the influence of using different vegetables oils (Linseed; Soybean; Olive) and fish oil (Cod liver) for Artemia metanauplii nutritional...

"Do not choose as I do!" - Dogs avoid the food that is indicated by another dog's gaze in a two-object choice task
| Contributor(s):: Balint, A., Farago, T., Meike, Z., Lenkei, R., Miklosi, A., Pongracz, P.
Family dogs successfully follow human-given cues in a two-object choice test. However, whether this ability has any roots in dog-dog visual communication, has been seldom investigated. We designed a test where a video-projected, life-sized dog 'demonstrator' provided directional cues for...

Ontogeny of daily activity and circadian rhythm in the Iberian lynx (Lynx pardinus)
| Contributor(s):: Yerga, J., Calzada, J., Manteca, X., Vargas, A., Perez, M. J., Palomares, F., Rivas, A.
The aim of this paper is to describe the ontogeny of the circadian activity rhythms in captive-born Iberian lynx ( Lynx pardinus) from birth to subadult age and to verify if they develop a bimodal circadian pattern similar to the one they show in the wild. The amount of daily activity and the...

A comparison of pet and purpose-bred research dog (Canis familiaris) performance on human-guided object-choice tasks
| Contributor(s):: Lazarowski, L., Dorman, D. C.
Several studies have shown that domestic dogs respond to human social cues such as pointing. Some experiments have shown that pet dogs outperformed wolves in following a momentary distal point. These findings have lent support to the hypothesis that domestication is responsible for domestic...

Contagious yawning in domestic dog puppies ( Canis lupus familiaris): the effect of ontogeny and emotional closeness on low-level imitation in dogs
| Contributor(s):: Madsen, E. A., Persson, T.
Contagious yawning is a well-documented phenomenon in humans and has recently attracted much attention from developmental and comparative sciences. The function, development and underlying mechanisms of the phenomenon, however, remain largely unclear. Contagious yawning has been demonstrated in...
