Aggressiveness and locomotion activity related to hatching time in Matrinxa, Brycon amazonicus (Spix and Agassiz, 1829)
Contributor(s):: Souza, E. C. M. de, Silva, J. P. da, Villacorta-Correa, M. A., Carvalho, T. B.
Since agonistic interaction has been a major obstacle for fish hatchery and represents great economic losses for fish farmers, aggressiveness during the different post-hatching stages of the matrinxa, Brycon amazonicus, is analyzed and compared. Each group of three larvae was observed at six...

Behavioral and hormonal consequences of transporting giant pandas from China to the United States
Contributor(s):: Snyder, R. J., Perdue, B. M., Powell, D. M., Forthman, D. L., Bloomsmith, M. A., Maple, T. L.
Zoological institutions strive to ensure the welfare of nonhuman animals in captivity. Part of this effort involves reducing the level of distress experienced by an animal to the greatest extent possible. However, some necessary zoo management practices such as transportation induce stress...
Behavioural and physiological responses of captive wombats ( Lasiorhinus latifrons ) to regular handling by humans
Contributor(s):: Hogan, L. A., Johnston, S. D., Lisle, A. T., Keeley, T., Wong, P., Nicolson, V., Horsup, A. B., Janssen, T., Phillips, C. J. C.
The response of animals to handling by humans has been extensively evaluated in domesticated livestock, but rarely examined in wildlife species. Twelve captive wombats (Lasiorhinus latifrons) were subjected to two treatments in a replicated design: (1) daily handling, involving 15 min of tactile...
Behavioural fear and heart rate responses of horses after exposure to novel objects: effects of habituation
Contributor(s):: Leiner, L., Fendt, M.
The emotion fear promotes the fitness of wild animals. In a farm environment, exaggerated fear, e.g., in horses, can cause several problems. Therefore, knowledge about fear in horses helps to prevent or to handle potential fear-inducing situations. The present study investigated which behavioural...

Choice of conflict resolution strategy is linked to sociability in dog puppies
Contributor(s):: Riemer, S., Muller, C., Viranyi, Z., Huber, L., Range, F.
Measures that are likely to increase sociability in dog puppies, such as appropriate socialisation, are considered important in preventing future fear or aggression related problems. However, the interplay between sociability and conflict behaviour has rarely been investigated. Moreover, while...
Consistency and stability of behavioural fear responses of heifers to different fear-eliciting situations involving humans
Contributor(s):: Mazurek, M., McGee, M., Crowe, M. A., Prendiville, D. J., Boivin, X., Earley, B.
This study investigated the consistency and stability of fear responses in housed beef heifers over time using three behavioural tests. The flight (time to join peers and avoidance distance), docility (isolation and handling) and fear (4 phases; responses of isolated heifers in (i), the absence...
Consistency of flight speed and response to restraint in a crush in dairy cattle
Contributor(s):: Gibbons, J. M., Lawrence, A. B., Haskell, M. J.
Flight speed (FS) is an objective measure of the behavioural response to handling procedures in beef cattle but to date there is no published work on dairy cattle. It is useful to determine whether there is consistency in FS in dairy cattle, and assess the relationship between FS and other...
Early life behavioural differences in wild caught and domesticated sea bass (Dicentrarchus labrax)

Effects of human handling during early rearing on the behaviour of dairy calves

Effects of obstructed take-off and landing perches on the flight accuracy of laying hens
Contributor(s):: Moinard, C., Rutherford, K. M. D., Haskell, M. J., McCorquodale, C., Jones, R. B., Green, P. R.
Laying hens housed in extensive systems may be at risk of injury when many birds compete for use of the same perch space. Experiments were carried out to determine the space required by laying hens to move between obstructed perches. Eighty Lohmann Brown layer hens were reared in floor pens...
Estimation of red-winged blackbird mortality from toxic bait application
Contributor(s):: James F. Glahn, Michael L. Avery
Application of slow-acting toxic bait is one method of reducing local populations of depredating blackbirds. Estimating numbers of birds killed in such baiting operations is difficult because affected birds die off-site and are seldom recovered. We conducted bioassays and flight pen studies of...
Exploration behaviour and flight response toward a stimulus in three sea bass strains ( Dicentrarchus labrax L.)
Contributor(s):: Millot, S., Begout, M. L., Chatain, B.
Domestication and selection may affect fish behaviour, sometime as soon as at the first generation of domestication. However, knowledge about how both processes impact on fish spatial exploration and swimming activity still is to be improved. The objective of this experiment was (i) to evaluate...
Exploring heifers' perception of 'positive' treatment through their motivation to pursue a retreated human
Contributor(s):: Bertenshaw, C. E., Rowlinson, P.
This pilot study investigates dairy heifers' perception of 'positive treatment' by a human (stroking and brushing) through a test of appetitive motivation. The hypothesis was that positive treatment by a human results in heifers pursuing a human to seek further positive treatment. Thirty-seven...
Fear reactions in trained and untrained horses from dressage and show-jumping breeding lines
Contributor(s):: Borstel, U. U. K. von, Duncan, I. J. H., Lundin, M. C., Keeling, L. J.
Horses' fear reactions are hazardous to both horses and human beings, but it is not clear whether fear is influenced more by training or by other factors such as genetics. The following study was designed to detect differences between young, untrained (U) and older, well-trained (T) horses of...
Fearfulness in horses: a temperament trait stable across time and situations
Contributor(s):: Lansade, L., Bouissou, M. F., Erhard, H. W.
The purpose of this study was to test the existence of a "fearfulness" trait in horses, by testing the stability across situations and over time of the responses to different fear-eliciting situations. It was also to identify which behavioural parameters are the best indicators of this trait....
Flight distance and reaction to fawn handling are greater in high- than in low-ranked pampas deer ( Ozotoceros bezoarticus) females
Contributor(s):: Ungerfeld, R., Morales-Pineyrua, J. T., Freitas-de-Melo, A.
The flight distance from humans and the reaction of the mother to human handling of their offspring are measures that can be used to assess the quality of the human-animal relationship which could vary according to animals' position in a group. The objective was to determine if the flight...
