  1. The effects of radar on avian behavior: implications for wildlife management at airports

    Contributor(s):: Sheridan, E., Randolet, J., DeVault, T. L., Seamans, T. W., Blackwell, B. F., Fernandez-Juricic, E.

    Airports often contain foraging, breeding, and roosting resources for wildlife. Airports also have different types of radars to assist with air traffic control, monitoring weather, and tracking wildlife that could become a risk for collision with aircraft. The effect of radar electromagnetic...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. Bird consumption of sweet and tart cherries

    Contributor(s):: Lindell, C. A., Eaton, R. A., Lizotte, E. M., Rothwell, N. L.

  7. Bird strikes and aircraft fuselage color: a correlational study

    Contributor(s):: Fernandez-Juricic, E., Gaffney, J., Blackwell, B. F., Baumhardt, P.

  8. Early life behavioural differences in wild caught and domesticated sea bass (Dicentrarchus labrax)

    Contributor(s):: Benhaim, D., Pean, S., Lucas, G., Blanc, N., Chatain, B., Begout, M. L.

  9. The influence of access to aerial perches on fearfulness, social behaviour and production parameters in free-range laying hens

    Contributor(s):: Donaldson, C. J., O'Connell, N. E.

  10. Wildlife risk to aviation: a multi-scale issue requires a multi-scale solution

    Contributor(s):: Martin, J. A., Belant, J. L., Devault, T. L., Blackwell, B. F., Burger, L. W., Jr., Riffell, S. K., Wang, G.

  11. 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...

  12. 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...

  13. 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...

  14. 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....

  15. Is the avoidance distance test for the assessment of animals' responsiveness to humans influenced by either the dominant or flightiest animal in the group?

    Contributor(s):: Mazurek, M., McGee, M., Minchin, W., Crowe, M. A., Earley, B.

    A previously described (Windschnurer et al., 2009) avoidance distance test was used to assess animals' fear of humans in order to quantify the human-animal relationship (HAR). This study investigated the influence of the dominant and flightiest animals within a group on the responsiveness of...

  16. Quality of handling and holding yard environment, and beef cattle temperament: 1. Relationships with flight speed and fear of humans

    Contributor(s):: Petherick, J. C., Doogan, V. J., Holroyd, R. G., Olsson, P., Venus, B. K.

    Numerous tests have been used to measure beef cattle temperament, but limited research has addressed the relationship between such tests and whether temperament can be modified. One-hundred-and-forty-four steers were given one of three human handling and yarding experiences on six occasions...

  17. Quality of handling and holding yard environment, and beef cattle temperament: 2. Consequences for stress and productivity

    Contributor(s):: Petherick, J. C., Doogan, V. J., Venus, B. K., Holroyd, R. G., Olsson, P.

    This experiment assessed the effects of different quality and quantity of handling and quality of the holding yard environment on the productivity and physiological parameters indicative of stress in beef cattle. One-hundred-and-forty-four steers were given one of three human handling and yarding...

  18. The genetics of temperament in merino sheep and relationships with lamb survival

    Contributor(s):: Plush, K. J., Hebart, M. L., Brien, F. D., Hynd, P. I.

    Investigations were made into the genetics of several temperament traits in Merino ewes, with particular emphasis on those aspects which might be associated with maternal behaviour at lambing and consequently, the postnatal survival of lambs. If a beneficial relationship between ewe temperament...

  19. The relationships between temperament during routine handling tasks, weight gain and facial hair whorl position in frequently handled beef cattle

    Contributor(s):: Olmos, G., Turner, S. P.

    A relationship has been described between facial hair whorl position and temperament in infrequently handled beef cattle when both traits were measured on categorical scales. Hair whorl position has also been found to relate to daily weight gain in dairy heifers. Using both a categorical scale...

  20. 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...
