  1. The Zoological Paradox

    Contributor(s):: Thorfun Chutchawanjumrut

    Through on-site field investigation, studies of animal behaviors, and Jon Coe’s zoo enrichment principles, this thesis proposes that zoo architec-ture should prioritize the needs of the animals by incorporating behavioral and environmental enrichments into its...

  2. Evaluation of an innovative approach for sensory enrichment in zoos: semiochemical stimulation for captive lions ( Panthera leo)

    Contributor(s):: Martinez-Macipe, M., Lafont-Lecuelle, C., Manteca, X., Pageat, P., Cozzi, A.

    Despite improvements in zoo housing and management conditions over the last years, zoo animals may still present undesirable behaviours, such as aggression, stereotypies, boredom and a general absence of natural behaviours. In order to improve animal welfare, researchers are constantly looking...

  3. Animal Enrichment Strategies for Promoting Natural Behaviors in Captive Populations of Tasmanian Devils (Sarcophilus harrisii)

    Contributor(s):: Tierney O\'neal

    The population of Tasmanian devils (Sarcophilus harrisii) is in rapid decline due to Devil Facial Tumour Disease, and insurance populations have been created in captivity for potential future introduction into the wild. Many problems can arise within captive animal populations including loss of...

  4. A case study of orangutan and siamang behavior within a mixed-species zoo exhibit

    Contributor(s):: Pearson, E. L., Davis, J. M., Litchfield, C. A.

    This empirical case study assessed the behavior and welfare of 2 orangutans (Pongo abelii) and 2 siamangs (Symphalangus syndactylus) within a mixed-species zoo exhibit. The study used instantaneous scan-sampling to record behavior, location, and interspecies proximity over 174 hr and...

  5. Effect of enclosure quality on reactivity and welfare of captive Soemmerring's gazelle ( Gazella soemmerringii )

    Contributor(s):: Mansour, A. A. H., Zakaria, A. H., Fraser, A. F.

    The welfare of nonhuman animals in zoos is a great challenge to the zookeeper. Changes in the behavioral response of captive animals to their immediate environment can be used as a method for evaluating their welfare status. This study evaluates reactive responses of 3 groups of captive...

  6. The use of positive reinforcement in training zebra sharks ( Stegostoma fasciatum)

    Contributor(s):: Marranzino, A.

    Positive reinforcement training (PRT) was used on 4 adult zebra sharks, Stegostoma fasciatum, housed at the Downtown Aquarium, Denver, to determine the ability of zebra sharks to become desensitized to various stimuli associated with veterinary procedures. One male and 3 female sharks were...

  7. Evaluation of factors affecting emotional responses in zoo visitors and the impact of emotion on conservation mindedness

    Contributor(s):: Powell, D. M., Bullock, E. V. W.

    Creating experiences for visitors that increase their biological knowledge and inspire conservation mindedness is a critical task for zoos and aquariums. A growing body of literature suggests that emotional stimulation is affected by characteristics of both the visitor and the visitor's...

  8. Welfare by the ear: comparing relative durations and frequencies of ear postures by using an automated tracking system in sheep

    Contributor(s):: Vogeli, S., Wechsler, B., Gygax, L.

    Given the increased interest in animal emotional reactions for assessing welfare, indicators for such reactions are sought. Ear postures and movements have been found to be promising indicators of emotional states in sheep and other animals. The manual recording of ear postures, however, is very...

  9. A survey of stakeholders' opinions on the priority issues affecting the welfare of companion dogs in Great Britain

    Contributor(s):: Buckland, E. L., Whiting, M. C., Abeyesinghe, S. M., Asher, L., Corr, S., Wathes, C. M.

  10. Electromagnetic induction of insensibility in animals: a review

    Contributor(s):: Small, A., McLean, D., Owen, J. S., Ralph, J.

  11. How "natural" training methods can affect equine mental state? A critical approach - a review

    Contributor(s):: Rozempolska-Rucinska, I., Trojan, M., Kosik, E., Prochniak, T., Gorecka-Bruzda, A.

  12. Measuring faecal glucocorticoid metabolites as a non-invasive tool for monitoring adrenocortical activity in South American camelids

    Contributor(s):: Arias, N., Requena, M., Palme, R.

  13. Acute effects of cage cleaning at different frequencies on laboratory rat behaviour and welfare

    Contributor(s):: Burn, C. C., Peters, A., Mason, G. J.

  14. Measuring the success of a farm animal welfare education event

    Contributor(s):: Jamieson, J., Reiss, M. J., Allen, D., Asher, L., Wathes, C. M., Abeyesinghe, S. M.

  15. Pain perception at slaughter

    Contributor(s):: Johnson, C. B., Gibson, T. J., Stafford, K. J., Mellor, D. J.

  16. Sensory stimulation as environmental enrichment for captive animals: a review

    Contributor(s):: Wells, D. L.

    In the wild, animals are exposed to an ever-changing array of sensory stimuli. The captive environment, by contrast, is generally much more impoverished in terms of the sensory cues it offers the animals housed within. In a bid to remedy this, and promote better welfare, researchers have started...

  17. A note on the influence of visual conspecific contact on the behaviour of sheltered dogs

    Contributor(s):: Wells, D. L., Hepper, P. G.

    The effects of visual contact with other dogs on the behaviour of dogs housed in a rescue shelter were examined. 407 dogs were studied: 212 dogs were housed in cages that allowed for visual contact with dogs in opposite pens; 195 dogs were deprived of visual contact with other dogs by being...

  18. Exploration as an indicator of good welfare in beef bulls: an attempt to develop a test for on-farm assessment

    Contributor(s):: Westerath, H. S., Laister, S., Winckler, C., Knierim, U.

    Exploration appears to be carried out for its own purpose due to being self-rewarding. Furthermore, it increases environmental certainty with the effect of increased predictability and control of the environment. We, therefore, supposed that exploratory behaviour is associated with positive...

  19. The effect of environmental stimulation on the development of behaviour in pigs

    Contributor(s):: Petersen, V., Simonsen, H. B., Lawson, L. G.

    16 litters were reared in barren or enriched environments from birth to slaughter. Enriched pens contained straw, logs and branches, whereas barren pens contained no floor materials or objects. Piglets were weaned at 5 weeks of age. Behaviour was monitored during weeks 4, 7 and 18. Pigs in the...

  20. Auditory stimulation as enrichment for zoo-housed Asian elephants ( Elephas maximus )

    Contributor(s):: Wells, D. L., Irwin, R. M.

    This study explored the effect of auditory stimulation on the behaviour and welfare of four zoo-housed, female Asian elephants (Elephas maximus). All animals were exposed, in an ABA design, to two conditions of auditory stimulation: a 'control' (no auditory stimulation), and an 'experimental'...
