  1. When dogs look back: inhibition of independent problem-solving behaviour in domestic dogs ( Canis lupus familiaris) compared with wolves ( Canis lupus)

    Contributor(s):: Udell, M. A. R.

    Domestic dogs have been recognized for their social sensitivity and aptitude in human-guided tasks. For example, prior studies have demonstrated that dogs look to humans when confronted with an unsolvable task; an action often interpreted as soliciting necessary help. Conversely, wolves persist...

  2. And say the cat responded? Getting closer to the feline gaze

    Contributor(s):: White, K.

  3. Animals in war, animals on war: new perspectives from a theater of species

    Contributor(s):: Chaudhuri, U.

  4. The effect of morphine on changes in behaviour and physiology in intraperitoneally vaccinated Atlantic salmon ( Salmo salar)

    Contributor(s):: Nordgreen, J., Bjorge, M. H., Janczak, A. M., Poppe, T., Koppang, E. O., Ranheim, B., Horsberg, T. E.

  5. Guidelines for police officers when responding to emergency animal incidents

    Contributor(s):: Hanyok, P. M.

  6. Behaviour of temperate and sub-tropical reef fishes towards a stationary SCUBA diver

    Contributor(s):: Watson, Dianne L., Harvey, Euan S.

  7. Comparative behaviour of free-ranging blackbirds (Turdus merula) and silvereyes (Zosterops lateralis) with hexose sugars in artificial grapes

    | Contributor(s):: Saxton, V. P., Hickling, G. J., Trought, M. C. T., Creasy, G. L.

    In order to detect bird responses to sugar parameters of ripening grapes, artificial grapes containing controlled concentrations of hexose sugars were offered to free-range blackbirds (Turdus merula) and silvereyes (Zosterops lateralis). Time-lapse video was used to observe the two species of...

  8. Do the stereotypies of pigs, chickens and mink reflect adaptive species differences in the control of foraging?

    | Contributor(s):: Mason, G., Mendl, M.

    Species differences in food-related stereotypies and natural foraging behaviour are discussed, and evolutionary explanations for these species differences, and reasons why apparent species differences in stereotypy may be artefacts of husbandry are postulated.

  9. A survey assessment of variables related to stereotypy in captive giraffe and okapi

    | Contributor(s):: Bashaw, M. J., Tarou, L. R., Maki, T. S., Maple, T. L.

    Stereotypic behaviour has been investigated in a wide variety of animals, but little published information is available on this problem in captive exotic ungulates. A survey was used to gather information on the prevalence of stereotypic behaviour in giraffe and okapi and to identify variables...

  10. Do variations in scanning behavior affect tolerance to human disturbance?

    | Contributor(s):: Fernandez-Juricic, E., Schroeder, N.

    Tolerance to human disturbance can be estimated as the distance at which animals become noticeably alert to humans. Although this alert distance has been studied before, no consideration has been devoted to the relationship between vigilance behaviour and the probabilities of detecting...

  11. Effects of mixed-species stocking and space allowance on the behaviour and growth of red deer hinds and ewes at pasture

    | Contributor(s):: Blanc, F., Theriez, M., Brelurut, A.

    A study was conducted to test whether the effects of space allowance on social interactions, activity patterns and growth rates of hinds reared at pasture in single-species groups, were modified by mixing them with ewes. 30 red deer hinds (10 months old) from the same breeding group and 30 ewes...

  12. Factor analysis of behaviour in the porcine and murine elevated plus-maze models of anxiety

    | Contributor(s):: Janczak, A. M., Andersen, I. L., Boe, K. E., Faerevik, G., Bakken, M.

    The elevated plus-maze, a widely used and well-validated test for studying anxiety-related behaviour in rodents, has recently been suggested for studying anxiety- or fear-related behaviour in swine. There are, however, clear evolutionary, and thus behavioural differences, between these two...

  13. Attachment to humans: a comparative study on hand-reared wolves and differently socialized dog puppies

    | Contributor(s):: Topal, J., Gacsi, M., Miklosi, A., Viranyi, Z., Kubinyi, E., Csanyi, V.

    Using the Strange Situation Test originally developed for testing the mother–infant relationship in humans, we compared the attachment behaviour of extensively socialized (hand-reared) dog, Canis familiaris, and wolf, Canis lupus, puppies towards their human caregiver with that of pet dog...

  14. A comparative approach to the study of Keeper-Animal Relationships in the zoo. (Special Issue: Zoo animal welfare.)

    | Contributor(s):: Carlstead, K.

    Research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal's fear of humans, can markedly limit the productivity and welfare of farm animals. This article begins to explore some of the factors that need to be considered to...

  15. Assessment of the welfare of working horses, mules and donkeys, using health and behaviour parameters

    | Contributor(s):: Pritchard, J. C., Lindberg, A. C., Main, D. C. J., Whay, H. R.

    Working animals provide an essential transport resource in developing countries worldwide. Many of these animals are owned by poor people and work in harsh environments, so their welfare is a cause for concern. A protocol was developed to assess the welfare of working horses, mules and donkeys in...

  16. Testing the efficacy of deterring systems in two gull species

    | Contributor(s):: Soldatini, C., Albores-Barajas, Y. V., Torricelli, P., Mainardi, D.

    During recent decades, populations of some gull species have dramatically increased causing management problems; as a result of this, a number of deterring systems have been implemented. In this study, three commonly used scaring methods (visual, acoustic, falconry) were tested at a refuse dump....

  17. Sexual stimulation in male sheep and goats

    | Contributor(s):: Price, E. O., Borgwardt, R., Orihuela, A., Dally, M. R.

    Previous research has shown that the sexual performance of male goats is enhanced by viewing the mating activities of other males prior to being placed with sexually receptive females. This same experience has no effect on the sexual performance of male sheep. In this experiment, 14 male goats...

  18. Site use of grazing cattle and sheep in a large-scale pasture landscape: a GPS/GIS assessment

    | Contributor(s):: Putfarken, D., Dengler, J., Lehmann, S., Hardtle, W.

    Year-round mixed-species grazing at low densities in large-scale pasture systems has become a popular conservation concept as it is assumed to maintain the valuable biodiversity of semi-open cultural landscapes. This study aims to elucidate which vegetation types are preferentially grazed by...

  19. Analysing dominance relationships by sociometric methods - a plea for a more standardized and precise approach in farm animals

    | Contributor(s):: Langbein, J., Puppe, B.

    Social dominance is a multidimensional phenomenon occurring in all gregarious farm animals and finds its reflection in a dominance hierarchy. Hence, numerous studies have tried to analyse dominance relationships as well as to correlate outcoming results (mostly individual ranks) with other...

  20. Comparative foraging strategies of sheep and goats in a T-maze apparatus

    | Contributor(s):: Hosoi, E., Swift, D. M., Rittenhouse, L. R., Richards, R. W.

    The foraging behaviour of 8 sheep and 11 goats was studied using a T-maze. In experiment 1, animals were given two free choices in the maze. In each case, selection of either arm would result in their obtaining high quality feed, a situation classified as a 'win'. Both species tended to return to...
