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...

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...
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...

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...
