  1. Activity budgets of captive Cape fur seals ( Arctocephalus pusillus) under a training regime

    Contributor(s):: Wierucka, K., Siemianowska, S., Wozniak, M., Jasnosz, K., Kieliszczyk, M., Kozak, P., Sergiel, A.

    Ethograms and time budgets are crucial for the behavioral assessment of nonhuman animals in zoos, and they serve as references for welfare research. This study was conducted to obtain detailed time budgets of trained Cape fur seals ( Arctocephalus pusillus) in captivity, to evaluate variations of...

  2. An empirical case study examining effectiveness of environmental enrichment in two captive Australian Sea Lions ( Neophoca cinerea )

    Contributor(s):: Smith, B. P., Litchfield, C. A.

    This case study examined the effect of environmental enrichment on the activity budgets of a male and female Australian Sea Lion (Neophoca cinerea) housed together at Adelaide Zoo. Using non-food-related (intrinsic) and food-related (extrinsic) enrichment objects, the study conducted an ABABA...

  3. The effect of land based seal watching tourism on the haul-out behaviour of harbour seals ( Phoca vitulina) in Iceland

    Contributor(s):: Granquist, S. M., Sigurjonsdottir, H.

    The effect of land-based seal watching on the haul-out pattern of harbour seals ( Phoca vitulina) was investigated between June and August of 2008-2010 on Vatnsnes, NW Iceland. The results showed that the behaviour and spatial haul-out pattern of seals was affected by the tourists. In 2009 the...

  4. The Canadian harp seal hunt: observations on the effectiveness of procedures to avoid poor animal welfare outcomes

    Contributor(s):: Daoust, P. Y., Caraguel, C.

  5. Behavioural responses of juvenile steller sea lions to abdominal surgery: developing an assessment of post-operative pain

    Contributor(s):: Walker, K. A., Horning, M., Mellish, J. A. E., Weary, D. M.

    Marking and tracking of marine mammals is required to gain a better understanding of life history traits; however, some marking procedures used are likely painful. Recent technological advances include intra-abdominally implanted archival telemetry devices for the life-long monitoring of...

  6. Behavioural responses of South American fur seals to approach by tourists - a brief report

    Contributor(s):: Cassini, M. H.

    I studied the responses (retreats, threats, attacks or leaving the rookery) of South American fur seals Arctocephalus australis to tourist approaches at a non-reproductive, continental colony of located in Cabo Polonio, Uruguay (34 degrees 24'S, 53 degrees 46'W). Fur seals tolerated relatively...

  7. Behavioural responses of juvenile Steller sea lions to hot-iron branding

    Contributor(s):: Walker, K. A., Mellish, J. A. E., Weary, D. M.

    Here we present the first data showing the post-branding behavioural responses in a marine mammal. Eleven captive juvenile Steller sea lions (Eumetopias jubatus) were observed for 3 days before and 3 days after hot-iron branding. Four of six monitored behaviours changed significantly after...

  8. A preliminary investigation of the effect of repeated pedestrian approaches to Weddell seals ( Leptonychotes weddellii )

    Contributor(s):: Petel, T. van P., Giese, M., Hindell, M.

    Repeated exposure to human activity can change the behavioural response of wildlife, having implications for management. Weddell seals (Leptonychotes weddellii) breeding close to Antarctic research stations are easily accessible and regularly visited by people. To investigate the responses of...

  9. Embodying anthropomorphism: contextualizing commonality in the material landscape

    Contributor(s):: Lulka, D.

    The status of anthropomorphism has changed in recent decades, allowing for in-depth consideration of its meaning and salience. Advocates of anthropomorphism have put forth a series of scientific and theoretical arguments to establish the concept's legitimacy. Nonetheless, while many advocates of...

  10. 'Animal Ethics Dilemma': an interactive learning tool for university and professional training

    Contributor(s):: Hanlon, A. J., Algers, A., Dich, T., Hansen, T., Loor, H., Sandoe, P.

    'Animal Ethics Dilemma' is a freely available computer-supported learning tool (www.animalethicsdilemma.net or www.aedilemma.net) which has been developed primarily for veterinary undergraduates but is applicable also to students in other fields of animal science. The objectives of the computer...

  11. Environmental enrichment reduces the performance of stereotypic circling behaviour in captive common seals ( Phoca vitulina )

    Contributor(s):: Grindrod, J. A. E., Cleaver, J. A.

    A simple, cheap and effective method of adding complexity to a captive environment is the use of environmental enrichment techniques. A number of enrichment devices were used in this study, focusing primarily on occupying more time in feeding/foraging behaviours of common seals. The performance...

  12. Serum cortisol in California sea lion pups ( Zalophus californianus californianus )

    Contributor(s):: Pedernera-Romano, C., Aurioles-Gamboa, D., Valdez, R. A., Brousset, D. M., Romano, M. C., Galindo, F.

    Marine ecosystems are exposed to a wide variety of factors that may produce disturbances in their structure and functioning. The Gulf of California supports fisheries, tourism, intensive agriculture, mining, and more recently, shrimp aquaculture. Under such conditions, animals are forced to cope...
